Answers and Rationale
Gauge your performance by counter checking your answers to the answers below. Learn more about the question by reading the rationale. If you have any disputes or questions, please direct them to the comments section.
1. Answer: C. Hypertension
- Option C: Hypertension, along with fever, and tenderness over the grafted kidney, reflects acute rejection.
2. Answer: A. Pain
- Option A: Sharp, severe pain (renal colic) radiating toward the genitalia and thigh is caused by urethral distention and smooth muscle spasm; relief from pain is the priority.
3. Answer: D. Decrease the size and vascularity of the thyroid gland.
- Option D: Lugol’s solution provides iodine, which aids in decreasing the vascularity of the thyroid gland, which limits the risk of hemorrhage when surgery is performed.
4. Answer: A. Liver Disease
- Option A: The client with liver disease has a decreased ability to metabolize carbohydrates because of a decreased ability to form glycogen (glycogenesis) and to form glucose from glycogen.
5. Answer: C. Leukopenia
- Option C: Leukopenia, a reduction in WBCs, is a systemic effect of chemotherapy as a result of myelosuppression.
6. Answer: C. Avoid foods that in the past caused flatus.
- Option C: Foods that bothered a person preoperatively will continue to do so after a colostomy.
7. Answer: B. Keep the irrigating container less than 18 inches above the stoma.”
- Option B: This height permits the solution to flow slowly with little force so that excessive peristalsis is not immediately precipitated.
8. Answer: A. Administer Kayexalate
- Option A: Kayexalate, a potassium exchange resin, permits sodium to be exchanged for potassium in the intestine, reducing the serum potassium level.
9. Answer: B. 28 gtt/min
- Option B: This is the correct flow rate; multiply the amount to be infused (2000 ml) by the drop factor (10) and divide the result by the amount of time in minutes (12 hours x 60 minutes)
10. Answer: D. Upper trunk
- Option D: The percentage designated for each burned part of the body using the rule of nines: Head and neck 9%; Right upper extremity 9%; Left upper extremity 9%; Anterior trunk 18%; Posterior trunk 18%; Right lower extremity 18%; Left lower extremity 18%; Perineum 1%.
11. Answer: C. Bleeding from ears
- Option C: The nurse needs to perform a thorough assessment that could indicate alterations in cerebral function, increased intracranial pressures, fractures and bleeding. Bleeding from the ears occurs only with basal skull fractures that can easily contribute to increased intracranial pressure and brain herniation.
12. Answer: D. may engage in contact sports
- Option D: The client should be advised by the nurse to avoid contact sports. This will prevent trauma to the area of the pacemaker generator.
13. Answer: A. Oxygen at 1-2L/min is given to maintain the hypoxic stimulus for breathing.
- Option A: COPD causes a chronic CO2 retention that renders the medulla insensitive to the CO2 stimulation for breathing. The hypoxic state of the client then becomes the stimulus for breathing. Giving the client oxygen in low concentrations will maintain the client’s hypoxic drive.
14. Answer: B. Facilitate ventilation of the left lung.
- Option B: Since only a partial pneumonectomy is done, there is a need to promote expansion of this remaining left lung by positioning the client on the opposite unoperated side.
15. Answer: A. Food and fluids will be withheld for at least 2 hours.
- Option A: Prior to bronchoscopy, the doctors spray the back of the throat with anesthetic to minimize the gag reflex and thus facilitate the insertion of the bronchoscope. Giving the client food and drink after the procedure without checking on the return of the gag reflex can cause the client to aspirate. The gag reflex usually returns after two hours.
16. Answer: C. hyperkalemia.
- Option C: Hyperkalemia is a common complication of acute renal failure. It’s life-threatening if immediate action isn’t taken to reverse it. The administration of glucose and regular insulin, with sodium bicarbonate, if necessary, can temporarily prevent cardiac arrest by moving potassium into the cells and temporarily reducing serum potassium levels.
- Options A, B, and D: Hypernatremia, hypokalemia, and hypercalcemia don’t usually occur with acute renal failure and aren’t treated with glucose, insulin, or sodium bicarbonate.
17. Answer: A. This condition puts her at a higher risk for cervical cancer; therefore, she should have a Papanicolaou (Pap) smear annually.
- Option A: Women with condylomata acuminata are at risk for cancer of the cervix and vulva. Yearly Pap smears are very important for early detection. Because condylomata acuminata is a virus, there is no permanent cure.
- Option C: Because condylomata acuminata can occur on the vulva, a condom won’t protect sexual partners.
- Option D: HPV can be transmitted to other parts of the body, such as the mouth, oropharynx, and larynx.
18. Answer: A. The left kidney usually is slightly higher than the right one.
- Option A: The left kidney usually is slightly higher than the right one. An adrenal gland lies atop each kidney.
- Option C: The average kidney measures approximately 11 cm (4-3/8″) long, 5 to 5.8 cm (2″ to 2¼”) wide, and 2.5 cm (1″) thick.
- Option B: The kidneys are located retroperitoneally, in the posterior aspect of the abdomen, on either side of the vertebral column.
- Option D: They lie between the 12th thoracic and 3rd lumbar vertebrae.
19. Answer: C. Blood urea nitrogen (BUN) 100 mg/dl and serum creatinine 6.5 mg/dl.
- Option C: The normal BUN level ranges 8 to 23 mg/dl; the normal serum creatinine level ranges from 0.7 to 1.5 mg/dl. The test results in option C are abnormally elevated, reflecting CRF and the kidneys’ decreased ability to remove nonprotein nitrogen waste from the blood.
- Option A: CRF causes decreased pH and increased hydrogen ions — not vice versa.
- Option B: CRF also increases serum levels of potassium, magnesium, and phosphorous, and decreases serum levels of calcium.
- Option D: A uric acid analysis of 3.5 mg/dl falls within the normal range of 2.7 to 7.7 mg/dl; PSP excretion of 75% also falls with the normal range of 60% to 75%.
20. Answer: D. Alteration in the size, shape, and organization of differentiated cells
- Option D: Dysplasia refers to an alteration in the size, shape, and organization of differentiated cells.
- Option A: The presence of completely undifferentiated tumor cells that don’t resemble cells of the tissues of their origin is called anaplasia.
- Option B: An increase in the number of normal cells in a normal arrangement in a tissue or an organ is called hyperplasia.
- Option C: Replacement of one type of fully differentiated cell by another in tissues where the second type normally isn’t found is called metaplasia.
21. Answer: D. Kaposi’s sarcoma
- Option D: Kaposi’s sarcoma is the most common cancer associated with AIDS.
- Options A, B, and C: Squamous cell carcinoma, multiple myeloma, and leukemia may occur in anyone and aren’t associated specifically with AIDS.
22. Answer: C. To prevent cerebrospinal fluid (CSF) leakage
- Option C: The client receiving a subarachnoid block requires special positioning to prevent CSF leakage and headache and to ensure proper anesthetic distribution.
- Options A, B, and D: Proper positioning doesn’t help prevent confusion, seizures, or cardiac arrhythmias.
23. Answer: A. Auscultate bowel sounds.
- Option A: If abdominal distention is accompanied by nausea, the nurse must first auscultate bowel sounds. If bowel sounds are absent, the nurse should suspect gastric or small intestine dilation and these findings must be reported to the physician.
- Option B: Palpation should be avoided postoperatively with abdominal distention.
- Options C and D: If peristalsis is absent, changing positions and inserting a rectal tube won’t relieve the client’s discomfort.
24. Answer: B. Lying on the left side with knees bent
- Option B: For a colonoscopy, the nurse initially should position the client on the left side with knees bent.
- Option A, C, and D: Placing the client on the right side with legs straight, prone with the torso elevated, or bent over with hands touching the floor wouldn’t allow proper visualization of the large intestine.
25. Answer: A. Blood supply to the stoma has been interrupted
- Option A: An ileostomy stoma forms as the ileum is brought through the abdominal wall to the surface skin, creating an artificial opening for waste elimination. The stoma should appear cherry red, indicating adequate arterial perfusion. A dusky stoma suggests decreased perfusion, which may result from interruption of the stoma’s blood supply and may lead to tissue damage or necrosis.
- Option B: A dusky stoma isn’t a normal finding.
- Option C: Adjusting the ostomy bag wouldn’t affect stoma color, which depends on blood supply to the area.
- Option D: An intestinal obstruction also wouldn’t change stoma color.
26. Answer: A. Applying knee splints
- Option A: Applying knee splints prevents leg contractures by holding the joints in a position of function.
- Option B: Elevating the foot of the bed can’t prevent contractures because this action doesn’t hold the joints in a position of function.
- Option C: Hyperextending a body part for an extended time is inappropriate because it can cause contractures.
- Option D: Performing shoulder range-of-motion exercises can prevent contractures in the shoulders, but not in the legs.
27. Answer: B. Urine output of 20 ml/hour.
- Option B: A urine output of less than 40 ml/hour in a client with burns indicates a fluid volume deficit.
- Option A: This client’s PaO2 value falls within the normal range (80 to 100 mm Hg).
- Option C: White pulmonary secretions also are normal.
- Option D: The client’s rectal temperature isn’t significantly elevated and probably results from the fluid volume deficit.
28. Answer: A. Turn him frequently.
- Option A: The most important intervention to prevent pressure ulcers is frequent position changes, which relieve pressure on the skin and underlying tissues. If pressure isn’t relieved, capillaries become occluded, reducing circulation and oxygenation of the tissues and resulting in cell death and ulcer formation.
- Option B: During passive ROM exercises, the nurse moves each joint through its range of movement, which improves joint mobility and circulation to the affected area but doesn’t prevent pressure ulcers.
- Option C: Adequate hydration is necessary to maintain healthy skin and ensure tissue repair.
- Option D: A footboard prevents plantar flexion and footdrop by maintaining the foot in a dorsiflexed position.
29. Answer: C. In long, even, outward, and downward strokes in the direction of hair growth
- Option C: When applying a topical agent, the nurse should begin at the midline and use long, even, outward, and downward strokes in the direction of hair growth. This application pattern reduces the risk of follicle irritation and skin inflammation.
30. Answer: A. Beta-adrenergic blockers
- Option A: Beta-adrenergic blockers work by blocking beta receptors in the myocardium, reducing the response to catecholamines and sympathetic nerve stimulation. They protect the myocardium, helping to reduce the risk of another infraction by decreasing myocardial oxygen demand.
- Option B: Calcium channel blockers reduce the workload of the heart by decreasing the heart rate.
- Option C: Narcotics reduce myocardial oxygen demand, promote vasodilation, and decrease anxiety.
- Option D: Nitrates reduce myocardial oxygen consumption but decrease left ventricular end-diastolic pressure (preload) and systemic vascular resistance (afterload).
31. Answer: C. Raised 30 degrees
- Option C: Jugular venous pressure is measured with a centimeter ruler to obtain the vertical distance between the sternal angle and the point of highest pulsation with the head of the bed inclined between 15 to 30 degrees.
- Options B and D: Increased pressure can’t be seen when the client is supine or when the head of the bed is raised 10 degrees because the point that marks the pressure level is above the jaw (therefore, not visible).
- Option A: In high Fowler’s position, the veins would be barely discernible above the clavicle.
32. Answer: D. Inotropic agents
- Option D: Inotropic agents are administered to increase the force of the heart’s contractions, thereby increasing ventricular contractility and ultimately increasing cardiac output.
- Options A and B: Beta-adrenergic blockers and calcium channel blockers decrease the heart rate and ultimately decreased the workload of the heart.
- Option C: Diuretics are administered to decrease the overall vascular volume, also decreasing the workload of the heart.
33. Answer: B. Less than 30% of calories from fat
- Option B: A client with low serum HDL and high serum LDL levels should get less than 30% of daily calories from fat.
- Options A, C, and D: The other modifications are appropriate for this client.
34. Answer: C. The emergency department nurse calls up the latest electrocardiogram results to check the client’s progress
- Option C: The emergency department nurse is no longer directly involved with the client’s care and thus has no legal right to information about his present condition. Anyone directly involved in his care (such as the telemetry nurse and the on-call physician) has the right to information about his condition. Because the client requested that the nurse update his wife on his condition, doing so doesn’t breach confidentiality.
35. Answer: B. Check endotracheal tube placement.
- Option B: ET tube placement should be confirmed as soon as the client arrives in the emergency department. Once the airways is secured, oxygenation and ventilation should be confirmed using an end-tidal carbon dioxide monitor and pulse oximetry.
- Option A: Next, the nurse should make sure L.V. access is established.
- Option D: If the client experiences symptomatic bradycardia, atropine is administered as ordered 0.5 to 1 mg every 3 to 5 minutes to a total of 3 mg.
- Option C: Then the nurse should try to find the cause of the client’s arrest by obtaining an ABG sample. Amiodarone is indicated for ventricular tachycardia, ventricular fibrillation, and atrial flutter – not symptomatic bradycardia.
36. Answer: C. 95 mm Hg
- Option C: Use the following formula to calculate MAP
MAP = systolic + 2 (diastolic)
MAP = 126 mm Hg + 2 (80 mm Hg)
MAP = 286 mm Hg
MAP = 95 mm Hg
37. Answer: C. Electrocardiogram, complete blood count, testing for occult blood, comprehensive serum metabolic panel.
- Option C: An electrocardiogram evaluates the complaints of chest pain, laboratory tests determine anemia, and the stool test for occult blood determines blood in the stool.
- Option A: Cardiac monitoring, oxygen, and creatine kinase and lactate dehydrogenase levels are appropriate for a cardiac primary problem. A basic metabolic panel and alkaline phosphatase and aspartate aminotransferase levels assess liver function.
- Option B: Prothrombin time, partial thromboplastin time, fibrinogen and fibrin split products are measured to verify bleeding dyscrasias.
- Option D: An electroencephalogram evaluates brain electrical activity.
38. Answer: D. Heparin-associated thrombosis and thrombocytopenia (HATT)
- Option D: HATT may occur after CABG surgery due to heparin use during surgery.
- Options B and C: Although DIC and ITP cause platelet aggregation and bleeding, neither is common in a client after revascularization surgery.
- Option A: Pancytopenia is a reduction in all blood cells.
39. Answer: B. Corticosteroids
- Option B: Corticosteroid therapy can decrease antibody production and phagocytosis of the antibody-coated platelets, retaining more functioning platelets.
- Option C: Methotrexate can cause thrombocytopenia.
- Options A and D: Vitamin K is used to treat an excessive anticoagulate state from warfarin overload, and ASA decreases platelet aggregation.
40. Answer: D. Xenogeneic
- Option D: A xenogeneic transplant is between is between human and another species.
- Options A, B, and C: A syngeneic transplant is between identical twins, allogeneic transplant is between two humans, and autologous is a transplant from the same individual.
