Nursing Elites

1. A patient is taking a thiazide diuretic and reports anorexia and fatigue. The nurse suspects which electrolyte imbalance in this patient?

• A. Hypercalcemia
• B. Hypocalcemia
• C. Hyperkalemia
• D. Hypokalemia

Correct answer: D

Rationale: The correct answer is D: Hypokalemia. Thiazide diuretics lead to potassium loss, potentially causing hypokalemia. Anorexia and fatigue are common manifestations of hypokalemia. Hypercalcemia (choice A) and hypocalcemia (choice B) are not directly associated with thiazide diuretics. Hyperkalemia (choice C) is less likely than hypokalemia to be caused by thiazide diuretics.

2. A healthcare professional is reviewing laboratory results for a client who is at risk for nephrotoxicity due to medications. Which of the following serum creatinine results does the healthcare professional document as normal?

• A. 0.2 mg/dL
• B. 1.0 mg/dL
• C. 2.8 mg/dL
• D. 3.9 mg/dL

Correct answer: B

Rationale: The normal serum creatinine level typically ranges from 0.6 to 1.3 mg/dL. A result of 1.0 mg/dL falls within this normal range. A serum creatinine level of 0.2 mg/dL is abnormally low and may indicate decreased muscle mass or malnutrition. On the other hand, results of 2.8 mg/dL and 3.9 mg/dL are elevated, signifying impaired kidney function and potential nephrotoxicity from medications.

3. After teaching a client with nephrotic syndrome and a normal glomerular filtration rate, the nurse assesses the client’s understanding. Which statement made by the client indicates a correct understanding of the nutritional therapy for this condition?

• A. I must decrease my intake of fat.
• B. I will increase my intake of protein.
• C. A decreased intake of carbohydrates will be required.
• D. An increased intake of vitamin C is necessary.

Correct answer: B

Rationale: In nephrotic syndrome, there is significant renal loss of protein leading to hypoalbuminemia and edema formation. If glomerular filtration is normal or near normal, increased protein loss should be matched by an increased intake of protein. Therefore, the correct statement indicating a correct understanding of the nutritional therapy for this condition is increasing protein intake. Decreasing fat, decreasing carbohydrates, or increasing vitamin C intake is not necessary for addressing the underlying issues associated with nephrotic syndrome.

4. Which lab result would be most indicative of renal failure?

• A. Elevated creatinine levels.
• B. Low potassium levels.
• C. Low calcium levels.
• D. High sodium levels.

Correct answer: A

Rationale: The correct answer is A: Elevated creatinine levels. Creatinine is a waste product that is normally filtered by the kidneys. Elevated creatinine levels indicate impaired kidney function, which is commonly seen in renal failure. Choice B, low potassium levels, is not typically associated with renal failure. In fact, renal failure is more likely to cause high potassium levels due to the kidneys' inability to excrete potassium effectively. Choice C, low calcium levels, are not directly indicative of renal failure. Renal failure can lead to disturbances in calcium levels, but low calcium levels alone are not a specific marker for renal failure. Choice D, high sodium levels, are also not typically associated with renal failure. In renal failure, there may be disturbances in sodium levels, but high sodium levels alone are not a direct indicator of renal failure.

5. 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.
