Nursing Elites

1. A client with a UTI and a history of recurrent infections asks why the provider has not yet prescribed an antibiotic. The nurse should explain that the provider has to wait for the results of which of the following laboratory tests to identify which antibiotic to prescribe?

• A. Gram stain
• B. Culture
• C. Sensitivity
• D. Specific gravity

Correct answer: C

Rationale: In the case of a UTI, a sensitivity test is crucial as it identifies the most effective antibiotic to target the specific microorganism causing the infection. This test helps in prescribing the appropriate antibiotic for successful treatment and preventing antibiotic resistance. While a Gram stain and culture are important in diagnosing a UTI, the sensitivity test specifically determines the most suitable antibiotic. Specific gravity, on the other hand, is not related to identifying the appropriate antibiotic for a UTI.

2. A client has a new prescription for Verapamil to treat angina. The nurse should instruct the client to monitor for which of the following adverse effects?

• A. Muscle pain
• B. Dry cough
• C. Peripheral edema
• D. Increased urination

Correct answer: C

Rationale: Verapamil, a calcium channel blocker, can cause peripheral edema due to vasodilation. Clients should monitor for this adverse effect characterized by swelling in the extremities. Muscle pain (choice A) is not a common adverse effect of Verapamil. Dry cough (choice B) is more commonly associated with ACE inhibitors. Increased urination (choice D) is not a typical adverse effect of Verapamil. Therefore, the correct answer is monitoring for peripheral edema.

3. A client has a new prescription for Verapamil. Which of the following instructions should the nurse include?

• A. Take this medication at bedtime.
• B. Monitor for signs of hyperglycemia.
• C. Avoid drinking grapefruit juice.
• D. Increase your intake of potassium-rich foods.

Correct answer: C

Rationale: The correct instruction for a client prescribed Verapamil is to avoid drinking grapefruit juice. Grapefruit juice can inhibit the metabolism of Verapamil, leading to increased blood levels of the medication. This can result in a higher risk of adverse effects, such as hypotension and bradycardia. Therefore, it is essential for the client to avoid grapefruit juice while taking Verapamil to prevent potential complications. Choices A, B, and D are incorrect because taking Verapamil at bedtime, monitoring for signs of hyperglycemia, and increasing potassium-rich foods intake are not specific instructions related to Verapamil therapy and do not address the potential interaction with grapefruit juice.

4. A client has a new prescription for Furosemide. Which of the following adverse effects should the nurse monitor?

• A. Hyperkalemia
• B. Hyponatremia
• C. Hypernatremia
• D. Hypercalcemia

Correct answer: B

Rationale: Furosemide is a diuretic that commonly causes hyponatremia (low sodium levels) due to its effect on sodium and water excretion. The nurse must closely monitor the client for signs of hyponatremia, such as weakness, confusion, and muscle cramps, and promptly intervene to prevent complications. Choices A, C, and D are incorrect because Furosemide is not associated with hyperkalemia, hypernatremia, or hypercalcemia. Understanding the medication's mechanism of action helps prioritize monitoring for potential adverse effects.

5. A client is receiving vancomycin. Which of the following laboratory results should be monitored to evaluate the therapeutic effect of this medication?

• A. BUN
• B. Creatinine
• C. Hemoglobin
• D. White blood cell count

Correct answer: B

Rationale: Corrected Rationale: Creatinine levels should be monitored to evaluate vancomycin's effect on kidney function. Vancomycin can be nephrotoxic, so monitoring creatinine levels helps assess renal function and ensure that the medication is not causing harm to the kidneys. Monitoring BUN (choice A) is important for assessing kidney function but is not as specific as monitoring creatinine levels. Hemoglobin (choice C) and white blood cell count (choice D) are not directly related to evaluating the therapeutic effect of vancomycin.
