RESPIRATORY – 5 items
1. Mr. A., a patient with status asthmaticus, becomes less responsive. Arterial blood gas analysis reveals a partial pressure of carbon dioxide in arterial blood (PaCO2) of 60mmHg and PaO2 of 55mmHg. The data most likely indicate acute:A. Pneumonitis
B. Respiratory failure
C. Pulmonary edema
D. Pulmonary embolism
Rationale:
B. A patient with status asthmaticus occasionally develops acute respiratory failure late in attack. This may occur with infections or pulmonary air leak, but it commonly occurs without evident complications. Exhaustion, coma, and deteriorating pulmonary function indicate a lack of response to therapy or deterioration. ; altered arterial blood gas levels ( partial pressure of carbon dioxide in arterial blood [PaCO2] below 50mmHg, partial pressure of oxygen in arterial blood [PaO2] below 50mmHg on 50% oxygen) indicate acute respiratory failure. The patient may need intubation or supportive ventilation. Acute pulmonary embolism causes initial sharp pain, hyperinflation, and respiratory alkalosis followed by respiratory acidosis. Acute pulmonary edema causes orthopnea, crackles, paroxysmal dyspnea, and pink, frothy sputum. Pneumonitis causes temperature elevation and purulent sputum.
M., a 19-year-old college student, is on the varsity football team. During a game, he is tackled and sustains fractured ribs on the right side of the chest. He is taken to the emergency department in a local hospital.
2. Which initial manifestation should the nurse expect with this patient?A. Shallow, painful breathing
B. Diminished breath sounds on the affected side
C. A clicking sensation during inspiration
D. Paradoxical respirations
Rationale:
A. Initial assessment to a patient with fractured ribs reveals a shallow breathing to minimize pain accompanying any movement. Paradoxical respirations, in which the chest expands on expiration and contracts on inspiration, would be present only if the ribs sustain multiple fractures. Diminished breath sounds on affect side, would be present only if the patient has pneumothorax. A clicking sensation would be present only with costochondrial separation.
3. Which condition would most likely indicate that M.’s chest tube should be removed?A. Lung reexpansion on chest x-ray
B. 120 ml of chest tube drainage in 24 hours
C. Cessation of pain and dyspnea
D. Absence of fluid fluctuation in the water-seal chamber
Rationale:
A. A chest x-ray must confirm lung reexpansion before chest tubes can be removed. The amount of chest tube drainage and the cessation of pain and dyspnea are not indications for removal. The presence of chest tubes itself may be irritating and painful; the pain may increase the patient’s dyspnea. Absence of fluid fluctuation in the water-seal chamber indicates lung reexpansion, but it could also mean that the chest tubes are obstructed or the drainage system is not working.
4. Which method would best prevent the air from entering the pleural cavity after removal of M.’s chest tubes?A. Breathing with an open mouth
B. Breathing through pursed lips
C. Performing Valsalva maneuver
D. Breathing quickly and shallowly (panting)
Rationale:
C. Valsalva’s maneuver causes bearing-down effect, increasing pressure through the cavity and preventing air from entering the pleural cavity. Breathing through pursed lips, quickly and shallowly, or with an open mouth will not prevent air from entering when chest tubes are removed.
Mr. S., a 65-year-old retired steel mill worker, is admitted to the unit with dyspnea upon exertion. He has a long history of smoking. Initial assessment includes barrel chest, ankle edema, persistent cough with copious sputum production, and variable wheezing on expiration. Laboratory test results include a hematocrit greater than 60% and a partial pressure of carbon dioxide in arterial blood gas (PaCO2) of 65mmHg. The physician diagnosed chronic obstructive pulmonary disease (COPD).
5. Mr. S.’s, ankle edema and respiratory problem would make the nurses suspect hypertrophy of the which heart chamber?A. Left ventricle
B. Right ventricle
C. Right atrium
D. Left atrium
Rationale:
B. Chronic obstructive pulmonary disease (COPD) can cause hypoxemia and pulmonary hypertension. Hypoxemia causes increased production of red blood cells, making the blood more viscous. The increased viscosity combined with increased pressure forces the right side of the heart to work harder than usual, resulting in right ventricular hypertrophy. Ankle edema is a common assessment finding in this situation. The right atrium may decompensate as the hypertrophy worsens; the left atrium and left ventricle are not affected.
CARDIAC SYSTEM
1 Intermittent claudication is an indication of which condition?A. Mitral regurgitation
B. Venous insufficiency
C. Arterial insufficiency
D. Phlebitis
Rationale:
C. Intermittent claudication typically is the first symptom of arterial insufficiency. It is not associated with phlebitis, venous insufficiency, or mitral regurgitation.
2 Which statement does not accurately describe Raynaud’s disease?A. It is precipitated by exposure to cold air or by emotional stress
B. Its is characterized by episodic digital vasospasm associated with skin color changes
C. It usually occurs in men ages 40 to 60
D. It is typically seen in fingers and toes
Rationale:
C. Raynaud’s disease usually occurs in woman ages 16 to 40, not older men. Intermittent constriction of cutaneous blood vessels, precipitated by exposure to cold or by emotional stress, produces cyanosis and pallor of the fingers or toes; reactive hyperemia after vasoconstriction causes redness.
Mr. S., age 36, is admitted to the hospital with a diagnosis of congestive heart failure (CHF). The
3 When assessing Mr. S., for signs and symptoms of digoxin toxicity, the nurse should watch all of the following except:A. Anorexia, nausea and vomiting, diarrhea, and abdominal pain
B. Bradycardia, tachycardia, bigeminy, ectopic beats, and pulse deficits
C. Abdominal distention, weakness, paralysis, apathy, depression, and hallucinations
D. Headache, double or blurred vision, drowsiness, confusion, restlessness, and muscle weakness.
Rationale:
C. Abdominal distention, weakness, apathy, paralysis, depression and hallucinations are signs of potassium and calcium overdose, not digoxin toxicity. The rest are all signs and symptoms of digoxin toxicity.
Mrs. J., a 58-year-old patient with long standing hypertension, is admitted for shortness of breath. During morning rounds the nurse notices that Mrs. J. has developed an S4 gallop, crackles, and diminished breath sounds, which indicate CHF.
4 Mrs. J., is admitted a year later with a diagnosis of malignant hypertension.
Which drug is commonly used to treat this disorder?A. ACE inhibitors and diuretics administered orally
B. Vasodilators and diuretics administered intravenously
C. Beta blockers and angiotensin converting enzymes (ACE) inhibitors administered orally
D. Adrenergic blockers and vasodilators administered intravenously
Rationale:
B. Malignant hypertension-rapid progression of primary or secondary hypertension-commonly is treated with potent vasodilator and loop diuretic. Nitroprusside (Nipride), the vasodilator of choice, can be titrated for pressure reduction when monitoring is available; diazoxide (Hyperstat), which acts directly on the peripheral arteriolar smooth muscle, may be given instead. Treatment must include a loop diuretic, usually furosemide. These drugs are given IV; their onsets of action are extremely fast. ACE inhibitors (which reduces peripheral arterial resistance without affecting heart rate or cardiac workload) and alpha-adrenergic blockers (which block peripheral vascular adrenergic receptors an cause vessel wall relaxation, resulting in peripheral vasodilation) as well as beta-adrenergic blockers (which decrease sympathetic stimulation and rennin secretion by the kidneys) may be used to treat primary or essential hypertension but not medical emergency like malignant hypertension.
Mr. T., a 57-year-old steelworker with a history of angina, has been having more frequent attacks of chest pain. He is admitted to the ED with chest pain unrelieved by three nitroglycerin tablets. The physician diagnosis Prinzmetal’s variant angina.
5 Mr.T.’s MI extends, and begins to show signs of left ventricular failure. Which sign would appear first?A. An S3 heart sound
B. An S4 heart sound
C. Pink, frothy sputum
D. Crackles an cough
Rationale:
A. The third heart sound (S3) is the first objective sign of left ventricular failure. Crackles and cough and pink, frothy sputum are late signs, signifying congestion from heart failure and pulmonary edema. A fourth heart sound (S4) is not a sign of left ventricular failure.
NEUROSENSORY SYSTEM 5 ITEMS
1. Which medication is not appropriate for a patient with a craniotomy?A. Phenytoin (Dilantin)
B. Codeine
C. Meperidine (Demerol)
D. Dexamethasone (decadron)
Rationale:
C. Meperine (Demerol) is not given postoperatively to a craniotomy patient because it may mask the neurologic problems, such as changes in level of consciousness and abnormal pupillary reactions or size; the drug may also cause respiratory depression. Dexamethasone (Decadron) is given to control cerebral edema. Phenytoin (Dilantin) is given to prevent generalized tonic-clonic seizures. Codeine is used as an analgesic for severe headache; this mild narcotic’s activity does not interfere with neurologic assessment.
2. All of the following signs indicate increased intracranial pressure except:A. Decreased level of consciousness
B. Papilledema
C. Vomiting
D. Tachycardia
Rationale:
D.Bradycardia, not tachycardia, accompanied by hypertension is a sign of increased intracranial pressure (ICP). Other signs include nausea and vomiting, decreased level of consciousness, and headache; papilledema is a late sign.
3. Which assessment most strongly suggest Meniere’s disease?A. Vertigo
B. Nausea
C. Neurosensory hearing loss
D. Tinnitus
Rationale:
A. The strongest indication of Meniere’s disease is vertigo, a sensation of irregular or whirling motion of oneself or of surrounding objects. Nausea commonly accompanies vertigo, but nausea by itself may be caused by many disease. Tinnitus (a buzzing sound in the eras) and neurosensory hearing loss occur in Meniere’s disease because of cochlear labyrinth disturbances (although hearing loss may not occur early in the disease); however, these findings also could result from other diseases. Vertigo accompanied tinnitus and neurosensory hearing loss confirms the diagnosis of Meniere’s disease.
4Characteristic clinical manifestation of ALS do not include:A. Uncontrolled outburst of crying
B. Aphagia and dysarthria
C. Loss of bowel and urine control
D. Fasciculation of the involved muscles
Rationale:
C. The patient with ALS usually does not lose urinary and bowel sphincter control because the disease does not affect the spinal nerves controlling these muscles. However, other muscles that control the neck, pharynx, larynx, trunk, and legs atrophy from the gradual degeneration of motor neurons; this can lead to aphagia, dysarthria, uncontrolled outburst of laughing or crying, and fasciculation of the involved muscles.
5. rs. D.’s physician orders myelogram using a water-soluble contrast medium. Which nursing activity is most appropriate for Mrs.D after his procedure?A. Monitoring level of consciousness
B. Restricting fluids for 6 to 10 hours
C. Placing the patient in a recumbent position for 12 to 24 hours
D. Elevating the head of the bed 15 to 30 degrees
Rationale:
D. After the patient has had a myelogram using a water-soluble contrast medium, the nurse should elevate the head of the bed 15 to 30 degrees to reduce the medium’s rate of upward dispersion, preventing such complications, such as seizures and transient encephalopathy. The nurse should encourage high fluid intake after myelogram to replenish CSF leakage and to maintain adequate hydration. Monitoring the patient’s level of consciousness is not necessary because myelogram will not alter it. The physician may specify a recumbent position for 12 to 24 hours after the procedure if oil-based iodine is used; this position helps prevent headache and may help reduce CSF leakage.
(Musculo) 5 items
1. A 15-year-old is treated in the emergency room for a fractured right ankle. A plaster walking cast is applied and the client is instructed to walk with the aid of crutches once the cast has dried. While instructing the client to ambulate with crutches the nurse most appropriately teaches the client to:A. Move both crutches and the right foot forward simultaneously followed by the left foot
B. Move the right foot and the left foot forward together followed by the left foot and right crutch
C. Move crutches and feet in the following sequence: right crutch, left foot, left crutch, right foot
D. Place the crutches under the arms, bear weight on the axilla, and position both crutches 8-10 inches in front of the body
Rationale:
A. This is the three point gait, which is used when one leg is injured or weak and the other leg is capable of supporting the client’s full body weight. Most of the body weight is placed on the crutches when the fractured rib is moved forward.
2. The nurse is assisting a client who has broken ankle with crutch walking. The nurse knows the client understands the instructions when the client:A. Leans on the crutch pads to relieve pressure on the affected foot
B. Advances both crutches and the affected leg at the same time
C. Puts partial weight on the affected side
D. Advances both crutches and the unaffected leg at the same time
Rationale:
B. The three point gait is the appropriate gait for someone with a broken ankle as it allows no weight bearing on the affected leg. The client advances both crutches and the affected leg at the same time. The client then swings the involved extremity to the crutches while the body’s weight is supported by the crutches and the unaffected leg.
3. A 2-day-old infant is diagnosed as having congenital hip dysplasia of the right hip. The infant is fitted with a Pavlick harness. Which of the following would not be included in the instructions for home care of the patients?A. Turn her every 3-4 hours
B. Watch for signs of skin breakdown
C. Keep her off the affected side
D. Give her sponge baths, not tub baths
Rationale:
C. The infant in a Pavlick harness can be turned from back to abdomen but should not be positioned to other side.
Mrs. D., a 32-year-old homemaker, is admitted to the hospital with a history of urine retention. Her physician suspects multiple sclerosis (MS).
4 Which diagnostic tool helps confirm the diagnosis of MS?A. Skull x-rays
B. Cerebrospinal fluids
C. Electromyography
D. Electroencephalography
Rationale:
B. Cerebrospinal fluid (CSF) analysis showing increased lymphocytes and oligoclonal immunoglobulin G helps confirm the diagnosis of MS. Other helpful diagnostic procedures include CT, nuclear magnetic resonance, and magnetic resonance imaging. Skull x-rays, electroencephalography, and electromyography do not diagnose MS.
Mr. C., a 65-year-old retired assembly line worker, is admitted to the hospital with a diagnosis of Parkinson’s disease.
5 The physician orders 1 mg of benztropine mesylate (Cogentin) P.O. daily for Mr. C., which finding suggests a favorable effect from this medication?A. Decreased tremors
B. Decreased muscle rigidity
C. Decreased confusion
D, Decreased dizziness
Rationale:
A. Anticholinergics, such as benztropine mesylate (Cogentin), reduce the cholinergic activity caused by decreased dopamine levels and decrease tremors. Muscle rigidity typically is treated with amantadine (Symmetrel) or carbodopa-levodopa (Sinemet). Possible adverse effect of anticholinergic drugs includes increased dizziness and confusion; benztropine therapy will not decrease this symptoms.
GASTROINTESTINAL SYSTEM
1. A client who is experiencing ascites is admitted to the hospital and will be undergoing a paracentesis. What should be included in the nursing care plan? A. Place client in Trendelenberg position for the procedure
B. Monitor client closely for evidence of vascular collapse
C. Have client remain on bed rest for 24 hours following the procedure
D. Encourage the client to drink plenty of fluids to distend the bladder prior to procedure
Rationale:
B. Removing large amounts of fluids may cause hypotension leading to vascular collapse. The client should be monitored closely for decrease in blood pressure, increase in pulse and pallor.
2. A woman is admitted for a suspected duodenal ulcer. The nurse is interviewing her for an admission history. Which description of her pain would be most characteristic of duodenal ulcer?A. Right upper quadrant that increases after meals
B. Aching in the epigastric area that wakens her from sleep
C. A sensation of painful pressure in the midsternal area
D. Sharp pain in the epigastric area that radiates to the right shoulder
Rationale:
B. Pain from a duodenal ulcer is often aching or burning in character. Pain occurs when the stomach is empty. In addition, in persons who develop duodenal ulcers often hyper secrete gastric acid during REM sleep, with a resulting increase in pain that wakens them from sleep.
Mr. F., age 60, is admitted to the hospital with ascites and jaundice to rule out cirrhosis of the liver.
3 The physician schedules Mr.F., for a liver biopsy to confirm the diagnosis of cirrhosis. Which crucial information should the nurse tell Mrs.F before the procedure?A. The procedure is painless
B. He should hold his breath on exhalation when biopsy needle is inserted
C. Pressure will be applied to his right side after the procedure
D. He must maintain a side-lying position after the procedure
Rationale:
B. to prevent puncture of the diaphragm, the nurse should tell the patient to hold his breath on exhalation when the needle is inserted. Because the patient may feel discomfort during needle insertion, he should not be told that the procedure is painless. After the procedure, the patient should lie in his right side on a pillow or a sandbag to arrest bleeding; however, this information is not crucial for the patient to know before the procedure.
Mr. M., a 42-year-old accountant, is admitted to the hospital with intestinal obstruction. A flat-plate x-ray of the abdomen shows a mass, which may be malignant.
4 Which type of tube will Mr. M.’s physician require for intestinal decompression?A. Levin
B. Salem sump
C. Ewald
D. Miller-Abbott
Rationale:
D. The physician will use the Miller-Abbott tube, a double-lumen tube with an inflatable balloon, to decompress the patient’s intestine. The Levin tube is a single-lumen nasogastric tube used to decompress the stomach. The Salem sump tube is a double-lumen tube used for stomach decompression. The Ewald tube is a large-bore tube used to evacuate the stomach.
Mr. O., a 50-year-old postal worker, is admitted to the hospital with acute pancreatitis.
5 If Mr. O., begins to exhibit muscle twitching and irritability, the nurse should:A. Call the physician because the patient may have hypocalcemia
B. Administer analgesics because the symptoms may be caused by pain
C. Check his serum amylase level
D. Reassure the patient that this is common among people who abuse alcohol
Rationale:
A. The nurse should call the physician immediately, because muscle twitching and irritability are signs of hypocalcemia, which commonly accompanies acute pancreatitis; other signs and symptoms include tetany, jerking, and positive Trousseau’s sign and Chvostek’s signs. Hypocalcemia results from the fixation of calcium by the fatty acids where fat necrosis has occurred and from the increased calcium loss in the urine.
ENDOCRINE and ONCOLOGY
1. Which medication is not an oral hypoglycemic agent?A. Glipizide (Glucotrol)
B. Tolbutamide (Orinase)
C. Chlorpropamide (Diabinese)
D. Diazoxide (Hyperstat)
Rationale:
D. Diazoxide (Hyperstat) is a benzothiadiazide that causes hyperglycemia by inhibiting insulin secretions; it is used to treat hypoglycemia by excessive insulin production. Chlorpropamide (Diabinase), Glipizide (Glucotrol), and Tolbutaline (Orinase) are oral hypoglycemic agents used to treat type II (non-insulin-dependent) diabetes mellitus. Chlorpropamide and tolbutamide are first-generation sulfonylureas that have been extensively used since 1965. Glipizide is a second-generation sulfonylurea approved for use in the United States in 1984; this medication is more potent than the first-generation ones and is associated with fewer complications.
2. When caring for Mrs. B., a diabetic patient starting prednisone (Deltasone) therapy for severe arthritis, the nurse should expect:A. Worsened diabetes control
B. No effect on diabetes control
C. Improved diabetes control
D. Frequent hypoglycemic reactions
Rationale:
A. Diabetes control worsens with the use of prednisone (Deltasone), a glucocorticoids and insulin antagonist. This drug increases glucose production by the liver and inhibits glucose use by the peripheral tissues; therefore, it increases the blood glucose level in diabetic patients and impairs diabetic control. Prednisone therapy may cause frequent hyperglycemic, not hypoglycemic, reactions by increasing blood glucose levels.
3. Parenteral injections of cortisol for patients with Addison’s disease should be injected:A. After the patient eats
B. Deep into the deltoid muscle
C. Deep into the gluteal muscle
D. Into the subcutaneous tissue
Rationale:
C. Because sufficient muscle mass is necessary for acute injection of Parenteral cortisol preparations, the nurse should inject them deep into the gluteal muscle. Cortisol should not be injected subcutaneously, because it may cause sterile abscesses, tissue atrophy, and pigmentation abnormalities. Steroid therapy causes GI disturbances with oral administration, not IM injection; therefore, the patient does not need to have food in his stomach before administration.
4 According to current American Cancer Society recommendations, women age 50 and over should have a routine mammography:A. Every 2 years
B. Every year
C. Only if symptomatic
D. Every 5 years
Rationale:
B. Because the risk of breast cancer begins to rise at age 40 and progressively increases through age 80, all women age 50 and over should follow the American Cancer Society recommendation for yearly mammography examinations.
5 Which assessment finding to a patient with prostatic cancer indicates metastasis?A. Pus in urine
B. Urinary frequency and decreased urinary stream
C. Decrease serum alkaline phosphatase level
D. A complaint of lumbosacral pain
Rationale:
D. A complaint of lumbosacral pain indicates metastasis; the most common form of metastasis by the hematogenous route is osseous, and the most common sites are the pelvis, lumbar spine, and ribs. Pus in the urine indicates urinary tract infection, not metastasis. Urinary frequency and decreased urinary stream are caused by urinary obstruction, not metastasis. The serum alkaline phosphatase level would be elevated, not decreased, with metastasis as a result of increased bone activity.
Mr. V., age 55, is admitted to the hospital with a diagnosis of chronic lymphocytic leukemia
6.During routine care, the patient asks the nurse,”How can I be anemic if this disease causes increased white cell production?” the nurse’s response would be that increased number of white blood cells (WBC):A. Are not responsible for the anemia
B. Crowd out red blood cells
C. Have an abnormally short life span
D. Use nutrients from other cells
Rationale:
B. Uncontrolled proliferation of granulocytes and monocytes causes leukemia, in which WBC’s are produced at a rapid rate, crowding out RBC’s. this reduces the amount of oxygen-transporting hemoglobin, resulting in anemia. The WBC’s do not use nutrients from other cells ar have abnormal life span.
7. Diagnostic assessment of Ms. V., would probably not reveal:A. Leukocytois with a shift from the left
B. Abnormal blast cells in the marrow
C. An elevated thrombocyte count
D. A predominance of lymphocytes
Rationale:
C. Assessment of the patient with leukemia typically reveals thrombocytopenia, rather than elevated thrombocyte count; with leukemia, an increase number in immature WBC’s are produced, crowding out platelets and RBC’s. Another common clinical manifestation of leukemia is an increased WBC count with increased release of band (immature) cells by the bone marrow-leukocytosis with a shift to the left. Blast cells, which are precursors of WBC’s, accumulate in the bone marrow with leukemia.
8. Several days after admission Mr.V., becomes disoriented and complains of frequent headaches. The nurse first action would be to:A. Raise the rails of the bed
B. Call the physician
C. Document the patient’s status on detail in her chart
D. Prepare oxygen equipment
Rationale:
A. Leukemia causes disorientation and headaches in the patient through WBC infiltration of the central nervous system (CNS); the nurse should raise the bed’s side rails to prevent falls. The nurse should document the assessment finding after taking action to prevent injury. Administering oxygen will not remove WBC’s from the CNS. The nurse should notify the physician of the patient’s condition change after ensuring her safety.
9. Which statement about bone marrow transplantation-the treatment of choice for patients under age 40 with leukemia-is not correct?A. The bone marrow aspirated is mixed with heparin
B. The patient is under local anesthesia
C. The recipient receives cyclophosphasmide (cytoxan) for 4 consecutive days
D. The aspiration site is the posterior or anterior iliac crest
Rationale:
B. The patient is under general or spinal anesthesia during bone marrow transplantation. The procedure involves the aspiration of approximately 600ml of bone marrow from the iliac crest; the marrow is mixed with heparin or frozen until given intravenously to the patient. Recipients are “primed” to prevent rejection by receiving cyclophosphasmide (cytoxan0 for 4 days before the transplant. The drug’s exact action is unknown; it has been found to have an immunosuppressive effect.
Mrs. R., age 53 has been experiencing bone pain, recurrent infections and abdominal pain for the past 5 years. After ordering a battery of tests, including x-ray studies, the physician diagnosed multiple myeloma.
10.The physician orders the administration of melphalan (Alkeran) for Mrs.R., because this drug causes pancytopenia, the nurse should assess the patient for:A. Decreased WBC count
B. Alopecia
C. Skin pigmentation
D. Thrombophlebitis
Rationale:
A. Pancytopenia refers to depression in all blood’s cellular elements; the patient on melphalen (Alkeran) therapy would probably have a reduced WBC count. Skin pigmentation is governed by melanocytes, which are controlled by pituitary gland; because melphalan affects bone marrow production of blood cells, the drug would cause skin pigmentation changes. Temporary alopecia and mild thrombophlebitis at the infusion site are adverse effects of melphalen therapy, but they are not related to pancytopenia.
HEMATOLOGIC AND INFECTIOUS 5 items
Ms. X., age25, complains of chronic fatigue, particularly after menstrual periods, which she says sometimes last for 6 days; her sanitary pads often are saturated in 2 hours. After a general prescribed oral ferrous sulfate (Feosol) therapy, Ms. X., remained fatigued and pale, and tiny bruises appear on her arms. An internist refers her then to a hematologist, who diagnosed idiopathic thrombocytopenic purpura (ITP) and admitted her to the hospital.
1. Which assessment finding is not typical of ITP?A. Prolonged activated partial thromboplastin time
B. Prolonged bleeding
C. Decreased platelet count
D. Increased capillary fragility
Rationale:
A. Prolonged partial thromboplastin time is not a typical of ITP. Thrombocytopenia refers to platelet count below 100,000/mm3, which is caused by premature platelet destruction. Normally, platelets survive 9 to 10 days; with thrombocytopenia, the survival rate is 2 to 3 days. Bone marrow aspiration reveals normal or increased megakaryocytes (precursor to platelets). Platelets form temporary clots, release incomplete thromboplastin, and maintain capillary integrity; they help close opening in the capillary walls and improve clot strength and retraction. Because of the low platelet count, bleeding is prolonged, capillary fragility is increased, and megakaryocytes are normal or increased. Platelets alone do not control bleeding, other coagulation factors from the intrinsic and extrinsic systems are necessary for homeostasis. Because these factors are intact, coagulation time is not affected; the activated partial thromboplastin is normal.
Mr. V., age 24, is an AIDS patient with a diagnosis of Pneumocytis carinii pneumonia. During 2 weeks of hospitalization with isolation precautions, he has had no visitors.
2. The patient with AIDS-related complex typically has a history of:A. Hairy leukoplakia of the tongue and a chronic cough
B. Oral candidiasis, molluscum, contagiosum, and bullous impetigo
C. Sever fatigue, lymphadenopathy, and diarrhea
D. Memory loss, night sweats, and disorientation
Rationale:
C. Although a patient with HIV infection may experience no ill effects, the history of a patient with AIDS-related complex typically includes severe fatigue, lymphadenopathy, bouts of diarrhea, malaise, weight loss, night sweats, oral thrush, or several of these disorders. Oral candidiasis, molluscum contagiosum, bullous impetigo, and memory loss by themselves do not necessarily imply HIV infection. Hairy leukoplakia indicates full-blown AIDS.
3. Which type of infection control does an extremely ill hospitalized patient with AIDS require?A. Blood and body fluid precautions
B. Respiratory isolation
C. Reverse isolation
D. Contact isolation
Rationale:
A. The patients with HIV infection requires blood and body fluid precautions because HIV is found in the blood and body fluid of infected persons. Therefore, health care providers wear gloves and gown to prevent contamination with feces, urine, bronchial secretions, or other body fluids. Because HIV is not transferred by droplet inspiration and casual contact, respiratory isolation and contact isolation are inappropriate. Reverse isolation, which protects the patient against infection from caregivers and visitors, are unnecessary.
4. How is Lyme disease treated?A. Antibiotic treatment with doxycycline or amoxicillin for 7-10 days.
B. Antibiotic treatment with cefuroxime axetil or erythromycin for 7-10 days.
C. There is no treatment; the disease must run its course.
D. Antibiotic treatment with doxycycline or amoxicillin for 3-4 weeks.
Rationale:
D. According to treatment experts, antibiotic treatment for 3-4 weeks with doxycycline or amoxicillin is generally effective in early disease. Cefuroxime axetil or erythromycin can be used for persons who are allergic to penicillin or who can not take tetracyclines. Later disease, particularly with objective neurologic manifestations, may require treatment with intravenous ceftriaxone or penicillin for 4 weeks or more, depending on disease severity. In later disease, treatment failures may occur and retreatment may be necessary.
A. Antibiotic treatment for 3-4 weeks with doxycycline or amoxicillin is generally effective in early disease.
B. Cefuroxime axetil or erythromycins are for those people who are allergic to penicillin or who cannot take tetracyclines. However, treatment lasts 3-4 weeks , not 7-10 days.
C. The proper antibiotic treatment for Lyme disease is an important strategy to avoid the morbidity and cost of complicated and late-stage illness.
5. A 30-year-old nonsmoking patient who is in general good health is diagnosed with acute bronchitis and is now being discharged. Which of the following patient responses indicate a need for further patient education?A. “I need to drink 8 to 10 glasses of water daily until I’m over this.”
B. “I should get a flu shot in about 6 weeks so I don’t get this again.”
C. “I can take over-the-counter cough suppressants to reduce my coughing at night.”
D. “I should come back to the hospital or see my doctor if my sputum turns rusty colored.”
Rationale:
B. A flu shot is helpful for individuals who are at high risk for respiratory complications. These include the elderly, people with chronic disease problems, and immunocompromised patients. The patient should understand that the timing is related not to the current episode but to seasonal exposure to infectious agents and that it takes several weeks to achieve immunity.
RENAL 5 items
1. A nurse is caring for a client who has had renal biopsy. Which of the following intervention would the nurse AVOID in the care of the client after this procedure?1. Ambulating the client in the room and hall for short distances.
2. Forcing fluids to at least 3 liters in the first 24 hours.
3. Administering PRN narcotics.
4 Testing serial samples with dipstick for occults blood.
Rationale:
1. After renal biopsy the nurse ensures that the client should remain in bed rest for at least 24 hors. Vital signs and puncture site assessments are done more frequently during this time. Forcing fluids is done to reduce possible clot formation at the biopsy site. Serial urine samples are hematested with urine dipsticks to evaluate bleeding. Narcotic analgesics are often needed to manage renal colic pain that some clients feel after the procedure.
2. The nurse is receiving in transfer from post anesthesia care unit client who has had percutaneous ultrasonic lithotripsy for calculi in the renal pelvis. The nurse anticipates that the client’s care will involve monitoring which of the following?1. Jackson-Pratt drain
2. Ureteral stent
3. Suprapubic tube
4. Nephrostomy tube
Rationale:
4. A nephrostomy tube is put in place after percutaneous ultrasonic lithotripsy to treat calculi in the renal pelvis. The client may also have Foley catheter to drain urine produced by the other kidney. The nurse monitors the drainage from each of the tubes, and strains the urine to detect elimination of the calculus fragments.
3. A client is admitted to an emergency department following a motor-vehicle accident. The client was wearing a lap seat belt when the accident occurred. The client has hematuria and lower abdominal pain. To further determine whether the pain is due to bladder trauma, a nurse asks the client if the pain is referred to which of the following areas?1. Umbilicus
2. Shoulder
3. Hip
4. Costovertebral angle
Rationale:
2. Bladder trauma or injury should be considered or suspected in the clients who have low abdominal pain and hematuria .Renal cancer would not cause pain that is felt in the low abdomen; rather it would be in the flank area. Glomerulonephritis and pyelonephritis is associated with fever, and are thus not applicable to the client in this question.
4. A client with chronic renal failure (CRF) returns to the nursing unit after following a hemodialysis treatment. On assessment the nurse notes that the client’s temperature is 100.20C. which of the following is the most appropriate nursing action?1. Encourage fluids
2. Continue to monitor vital signs
3. Notify the physician
4. Monitor the site of the shunt for infection
Rationale:
2. The client may have elevated temperature after the dialysis because the dialysis machine warms the blood slightly. If the temperature remains excessive extensively, and remains elevated, sepsis would be suspected and a blood sample should be obtained as prescribed for culture and sensitivity determinations.
5. A client passes a urinary stone, and laboratory analysis of the stone indicates that the stone is composed of calcium oxalate. On the basis of this analysis, the nurse would include which of the following in the client’s dietary instructions?1. Avoid green leafy vegetables, such as spinach
2. Avoid citrus fruits and citrus juices
3. Increase intakes of meat, fish, plum and cranberries
4. Increase intake of dairy products
rationale:
1. Oxalate is found in dark green food such as spinach. Other foods that raise urinary oxalate are rhubarb, strawberries, chocolates, whet bran, nuts, beets, and teas.
Fluid & Electrolytes- 5 items
1. Your post-operative client is to receive potassium chloride. Regarding the administration of IV potassium, you know:1. potassium may be given as a straight intravenous push to avoid fluid overload
2. potassium is usually mixed 1000 mEq/1000 cc of IV fluid
3. intravenous potassium may only be mixed in normal saline
4. intravenous potassium should be administered through a large vein
A: 4. To avoid irritation, a large IV bore into a large vein is recommended when administering potassium (K). IV potassium is very irritating to tissues & veins & may cause irritation @ the injection pathway.
1. Potassium given intravenously must always be diluted. Each dose should be diluted & mixed in 100 to 1000 ml of sol’n. The mix is usually 40-80 mEq/l depending upon the degree of hypokalemia.
2. K given intravenously is usually mixed 40-80 mEq/l depending upon the degree of hypokalemia.
3. K given intravenously can be mixed w/ many IV sol’ns, including D5W, normal saline, & Ringer’s sol’n

2. A client with DM is admitted with a UTI. The initial assessment reveals T-102.5, P-98, BP-97/65, and blood glucose 300 mg/dL. Prescriptions read: Intravenous fluids 5 % dextrose in water to infuse @ 100 mL/ hr, cefoxitin (Mefoxin) 1 gm intravenously q 4 hrs, acetaminophen (Tylenol) 650 mg by mouth every 4 hrs for temp. greater than 101.5 deg. F or pain, & sliding scale insulin for elevated blood glucose. Which prescriptions will be questioned?1. cefoxitin (Mefoxin) 1 gm intravenously q 4 hrs
2. D5W intravenous infusing 100 mL/hr
3. acetaminophen (Tylenol) 650 mg by mouth q 4 hrs
4. sliding scale insulin
A: 2. The administration of D5W should be questioned in this situation. D5W contains glucose, so it is an inappropriate IV sol’n for a diabetic client. The client’s blood glucose is 3oo mg/dl. Giving additional glucose would elevate the blood glucose level further. A hypotonic sol’n of ).45% NaCl is preferred. An intravenous rate of 100 ml/hr is appropriate for rehydration.
1. Cefoxitin (Mefoxin) is the drug of choice for UTI & would not be questioned
3. Tylenol can be given as an antipyrewtic or analgesic & is appropriate for the client’s condition.
4.Sliding scale insulin is an appropriate regimen prescribed for short-term mngt. Of elevated bld glucose
Pregnancy Category: C
Client Need: Physiological Integrity
3. A client with diabetes is experiencing DKA & is to receive intravenous fluids containing sodium bicarbonate. Regarding the administration of this intravenous fluid you know:1. sodium bicarbonate administration may result in alkalosis
2. most medications are compatible with sodium bicarbonate
3. sodium bicarbonate may not be given as an intravenous bolus or push
4. sodium bicarbonate may only be given IM
A: 1. Administering sodium bicarbonate (NaHCO3) may cause alkalosis. NaHCO3 is an electrolytereplenisher & alkalizing agent. Acidotic clients (pH<7.35) are given Na HCO3 to raise the pH. Excessive administration may cause alkalosis (pH>7.45).
2. Many meds are incompatible w/ Na HCO3.
3. NaHCO3 may be given as an IV push.
4. NaHCO3 is usually only given by mouth or intravenously.

Client Need (CN): Physiological Integrity
4. A client enters the hospital in acute renal failure. The client complains of drowsiness, nausea & has Kussmaul’s breathing. Lab tests show a serum potassium of 6.8, serum sodium of 120, & bld pH of 7.2. W/c of the ff MD’s prescriptions should be questioned?1. polystyrene sodium sulfonate (Kayexalate) 50 mg per rectum as enema
2. 2000-calorie, high carbohydrate, high protein diet when nausea subsides
3. hypertonic glucose (25%) 300 cc w/ regular insulin per IV infusion over 1 hour
4. limit po fluids per 8 hrs to no more than 100cc above the urinary output for the previous 8 hrs
A: 2. Dietary protein is usually eliminated in acute renal failure to decrease nitrogenous metabolic waste products.
1. Kayexalate reduces serum potassium by exchanging sodium for potassium ions in the GIT. Inasmuch as this client is hyperkalemic & hyponatremic, this is a reasonable prescription.
3. Hypertonic glucose & insulin promote mov’t of potassium into the cells, reducing hyperkalemia.
4. Fluid balance must be carefully monitored. Intake should be slightly more than output per 24 hrs as rapid changes may occur. Intake is frequently based on the prior 8-hr fluid output.

5. A blunt trauma patient with a descending thoracic aortic tear has been rapidly transfused with 12 units of packed RBC. Based on the observation, the ED nurse should anticipate which of the following blood products?BP 96/64 mmHg PT 38 sec Hct 30%
HR 132/min PTT 105 sec
Respirations 19/min PLT 88,000/mm3
Hgb 11g/dl
A. Fresh frozen plasma
B. Cryoprecipitate
C. Platelets
D. Packed red blood cells
Rationale:
A. fresh frozen plasma expands vascular volume and restores a wide variety of clotting factors to correct the PT/PTT.
B. Cryoprecipitate restores some clotting factors but is more expensive and more complicated to prepare and administer than fresh frozen plasma. It does not expand vascular volume and is not used as an initial treatment for prolonged PT/PTT.
C. This patient’s platelet count is adequate.
D. Packed red blood cells contain no clotting factors and would not correct PT/PTT.
