Nursing Elites

1. The nurse is preparing to administer clarithromycin to a patient. When performing a medication history, the nurse learns that the patient takes warfarin to treat atrial fibrillation. The nurse will perform which action?

• A. Ask the provider if azithromycin may be used instead of clarithromycin.
• B. Obtain an order for continuous cardiovascular monitoring.
• C. Request an order for periodic serum warfarin levels.
• D. Withhold the clarithromycin and notify the provider.

Correct answer: C

Rationale: When a patient taking warfarin also needs to receive clarithromycin, it is essential to monitor periodic serum warfarin levels. Macrolides, including clarithromycin, can increase serum levels of drugs like warfarin. Monitoring serum drug levels helps ensure that the patient's warfarin dose can be adjusted, if necessary, to maintain therapeutic levels. Asking about using azithromycin instead is not the most appropriate action in this situation, as all macrolides can interact with warfarin. Continuous cardiovascular monitoring is not indicated solely based on the use of clarithromycin. Withholding the clarithromycin without proper assessment could delay necessary treatment and is not the best initial action.

2. A client is undergoing hemodialysis. The client’s blood pressure at the beginning of the procedure was 136/88 mm Hg, and now it is 110/54 mm Hg. What actions should the nurse perform to maintain blood pressure? (Select all that apply.)

• A. Adjust the rate of extracorporeal blood flow.
• B. Place the client in the Trendelenburg position.
• C. Administer a 250-mL bolus of normal saline.
• D. All of the above

Correct answer: D

Rationale: During hemodialysis, a drop in blood pressure can occur due to fluid removal. To maintain blood pressure, the nurse should consider adjusting the rate of extracorporeal blood flow to optimize fluid removal without causing hypotension. Placing the client in the Trendelenburg position can help improve venous return and cardiac output. Administering a bolus of normal saline can help increase intravascular volume and support blood pressure. Therefore, all the actions listed in choices A, B, and C are appropriate measures to maintain blood pressure during hemodialysis. Choice D, 'All of the above,' is the correct answer as it encompasses all the relevant actions to address the dropping blood pressure effectively. Choices A, B, and C, when implemented together, can help manage hypotension during hemodialysis.

3. A client with chronic renal failure is on a low-protein diet. Which of the following is the best response by the nurse when the client asks why this diet is necessary?

• A. It reduces the workload on your kidneys.
• B. It helps prevent the buildup of waste products.
• C. It helps maintain electrolyte balance in your body.
• D. It helps prevent dehydration.

Correct answer: B

Rationale: A low-protein diet is necessary for clients with chronic renal failure because it helps prevent the buildup of waste products, such as urea, in the body. Excess protein can lead to the accumulation of waste products that the compromised kidneys may not effectively filter out, further burdening the already impaired renal function. Choices A, C, and D are incorrect because the primary reason for a low-protein diet in chronic renal failure is to reduce the workload on the kidneys by minimizing the production of waste products that can exacerbate the condition, not specifically to reduce kidney workload, maintain electrolyte balance, or prevent dehydration.

4. Which of the following is a characteristic symptom of hypothyroidism?

• A. Fatigue.
• B. Weight gain.
• C. Cold intolerance.
• D. Heat intolerance.

Correct answer: C

Rationale: The correct answer is 'Cold intolerance.' Hypothyroidism is associated with a decreased metabolic rate, leading to a decreased ability to regulate body temperature and a feeling of being cold. Fatigue (Choice A) and weight gain (Choice B) are also common symptoms of hypothyroidism due to the overall slowing down of bodily functions. Heat intolerance (Choice D) is more commonly associated with hyperthyroidism, where the body's metabolism is overactive, leading to increased heat production.

5. The nurse is preparing to administer intravenous gentamicin to an infant through an intermittent needle. The nurse notes that the infant has not had a wet diaper for several hours. The nurse will perform which action?

• A. Administer the medication and give the infant extra oral fluids.
• B. Contact the provider to request adding intravenous fluids when giving the medication.
• C. Give the medication and obtain a serum peak drug level 45 minutes after the dose.
• D. Hold the dose and contact the provider to request a serum trough drug level.

Correct answer: D

Rationale: In this scenario, the infant not having a wet diaper for several hours indicates a potential decrease in urine output, which can be a sign of nephrotoxicity related to gentamicin. The correct action for the nurse is to hold the dose and contact the provider to request a serum trough drug level. This is important to monitor the drug levels and ensure that they are not reaching toxic levels. Administering the medication without addressing the decreased urine output could potentially lead to further nephrotoxicity. Contacting the provider to add intravenous fluids or obtaining a serum peak drug level are not the most appropriate actions in this situation as the priority is to assess for potential nephrotoxicity and ensure patient safety.
