Nursing Elites

1. A patient with heart failure is prescribed digoxin. What is the most important instruction the nurse should provide?

• A. Take an extra dose if you miss one.
• B. Avoid high-potassium foods.
• C. Report any visual disturbances.
• D. Stop taking the medication if your pulse is normal.

Correct answer: C

Rationale: The correct answer is C: 'Report any visual disturbances.' Patients taking digoxin should be instructed to report any visual disturbances, as this can be a sign of digoxin toxicity. Visual disturbances like changes in color vision, blurred vision, or seeing halos around lights can indicate an overdose of digoxin. Choices A, B, and D are incorrect. Instructing a patient to take an extra dose if they miss one can lead to overdose. Avoiding high-potassium foods is important for patients on potassium-sparing diuretics, not digoxin. Stopping the medication if the pulse is normal is incorrect, as the pulse rate alone is not an indicator of digoxin effectiveness or toxicity.

2. A patient with chronic kidney disease (CKD) is prescribed calcium acetate. What is the primary purpose of this medication?

• A. Treat hyperkalemia
• B. Reduce phosphate levels
• C. Lower blood pressure
• D. Increase hemoglobin levels

Correct answer: B

Rationale: The primary purpose of prescribing calcium acetate to a patient with chronic kidney disease (CKD) is to reduce phosphate levels. Calcium acetate binds to dietary phosphate, preventing its absorption and helping to manage hyperphosphatemia commonly seen in CKD patients.

3. Why is a low-protein diet recommended for a patient with renal failure?

• A. To prevent fluid overload
• B. To reduce nitrogenous waste
• C. To maintain electrolyte balance
• D. To prevent hyperglycemia

Correct answer: B

Rationale: A low-protein diet is crucial for patients with renal failure to reduce the generation of nitrogenous waste products like urea and creatinine, which the compromised kidneys struggle to eliminate effectively. By limiting protein intake, the production of these waste products is decreased, lessening the burden on the kidneys and helping to manage the progression of renal failure. Choices A, C, and D are incorrect because a low-protein diet primarily aims to reduce the workload on the kidneys by decreasing the production of nitrogenous waste, not to prevent fluid overload, maintain electrolyte balance, or prevent hyperglycemia.

4. The nurse is administering sevelamer (RenaGel) during lunch to a client with end-stage renal disease (ESRD). The client asks the nurse to bring the medication later. The nurse should describe which action of RenaGel as an explanation for taking it with meals?

• A. Prevents indigestion associated with the ingestion of spicy foods.
• B. Binds with phosphorus in foods and prevents absorption.
• C. Promotes stomach emptying and prevents gastric reflux.
• D. Buffers hydrochloric acid and prevents gastric erosion.

Correct answer: B

Rationale: Sevelamer (RenaGel) binds with phosphorus in foods and prevents its absorption. By taking RenaGel with meals, the binding of phosphorus helps to reduce the phosphorus load absorbed from food, thus aiding in the management of hyperphosphatemia in clients with ESRD.

5. A client with a history of hypertension is prescribed hydrochlorothiazide. Which instruction should the nurse include in the client's teaching?

• A. Take this medication in the morning.
• B. Avoid foods high in potassium.
• C. Monitor your blood pressure regularly.
• D. Decrease your intake of high-sodium foods.

Correct answer: C

Rationale: Regular monitoring of blood pressure is crucial for individuals with hypertension to assess the effectiveness of the prescribed medication and to ensure blood pressure is within the target range. This helps in managing hypertension and preventing complications associated with high blood pressure. Choices A, B, and D are incorrect because while taking the medication in the morning may be recommended for some drugs, it is not the key instruction for hydrochlorothiazide. Avoiding foods high in potassium and decreasing high-sodium foods are important dietary considerations for certain conditions, but they are not the immediate focus when starting hydrochlorothiazide.
