Nursing Elites

1. The nurse is preparing to administer the first dose of hydrochlorothiazide (HydroDIURIL) 50 mg to a patient who has a blood pressure of 160/95 mm Hg. The nurse notes that the patient had a urine output of 200 mL in the past 12 hours. The nurse will perform which action?

• A. Administer the medication as ordered.
• B. Encourage the patient to drink more fluids.
• C. Hold the medication and request an order for serum BUN and creatinine.
• D. Request an order for serum electrolytes and administer the medication.

Correct answer: C

Rationale: The correct action is to hold the medication and request an order for serum BUN and creatinine. Thiazide diuretics, such as hydrochlorothiazide, are contraindicated in renal failure. In this case, the patient has oliguria, which is a reduced urine output, indicating potential renal insufficiency. Before administering the diuretic, it is crucial to evaluate the patient's renal function through serum BUN and creatinine levels. Encouraging the patient to drink more fluids (Choice B) may not address the underlying issue of renal function. Administering the medication as ordered (Choice A) without assessing renal function can be harmful. Requesting serum electrolytes and administering the medication (Choice D) overlooks the need for a specific evaluation of renal function in this scenario.

2. The nurse is administering intravenous fluids to a dehydrated patient. On the second day of care, the patient's weight has increased by 2.25 pounds. The nurse would expect that the patient's fluid intake has

• A. equaled urine output.
• B. exceeded urine output by 1 L.
• C. exceeded urine output by 2.5 L.
• D. exceeded urine output by 3 L.

Correct answer: B

Rationale: A weight gain of 1 kg, or approximately 2.2 to 2.5 lb, is generally equivalent to 1 liter (L) of fluid retained by the body. In this case, the patient's weight gain of 2.25 pounds suggests an excess fluid retention of approximately 1 liter, indicating that the patient's fluid intake has exceeded urine output by 1 liter. Choices C and D are incorrect as they overestimate the fluid excess based on the patient's weight gain. Choice A is incorrect as it implies an exact balance between fluid intake and urine output, which is not reflected in the given weight increase.

3. A patient has been taking spironolactone (Aldactone) to treat heart failure. The nurse will monitor for

• A. hyperkalemia.
• B. hypermagnesemia.
• C. hypocalcemia.
• D. hypoglycemia.

Correct answer: A

Rationale: The correct answer is A: hyperkalemia. Spironolactone is a potassium-sparing diuretic commonly used in heart failure management. One of the major side effects of spironolactone is hyperkalemia, which is an elevated level of potassium in the blood. Monitoring for hyperkalemia is crucial as it can lead to serious cardiac arrhythmias. Choices B, C, and D are incorrect. Hypermagnesemia (choice B) is not typically associated with spironolactone use. Hypocalcemia (choice C) and hypoglycemia (choice D) are also not directly linked to the use of spironolactone in heart failure treatment.

4. Which of the following is a common cause of chronic liver disease?

• A. Alcohol abuse.
• B. Hepatitis C infection.
• C. Obesity.
• D. Smoking.

Correct answer: B

Rationale: Hepatitis C infection is a common cause of chronic liver disease due to its long-term effects on the liver. Hepatitis C can lead to liver inflammation, fibrosis, cirrhosis, and even liver cancer. Alcohol abuse can also cause liver damage, but hepatitis C infection is specifically known for its chronic impact on liver health. Obesity and smoking, while detrimental to overall health, are not typically direct causes of chronic liver disease like hepatitis C infection.

5. When assessing the lower extremities of a client with peripheral vascular disease (PVD), the nurse notes bilateral ankle edema. The edema is related to:

• A. Competent venous valves.
• B. Decreased blood volume.
• C. Increase in muscular activity.
• D. Increased venous pressure.

Correct answer: D

Rationale: The correct answer is 'Increased venous pressure.' In peripheral vascular disease (PVD), impaired blood flow leads to increased venous pressure in the lower extremities, causing fluid to leak out of the blood vessels and accumulate as edema. Choice A, 'Competent venous valves,' is incorrect because in PVD, the venous valves may be incompetent, contributing to venous pooling and edema. Choice B, 'Decreased blood volume,' is incorrect as PVD is associated with impaired blood flow rather than reduced blood volume. Choice C, 'Increase in muscular activity,' is incorrect as it does not directly relate to the development of edema in PVD.
