A client with congestive heart failure is prescribed a loop diuretic. The nurse should closely monitor the client for which electrolyte imbalance associated with this medication?

Hyponatremia

Hypocalcemia

Hyperkalemia

Hypokalemia

Answer and Explanation

The Correct Answer is D

A) This choice is incorrect because loop diuretics can lead to increased sodium excretion, potentially causing hypernatremia (high sodium levels) rather than hyponatremia (low sodium levels).

B) This choice is incorrect because loop diuretics do not typically cause hypocalcemia (low calcium levels). They primarily affect sodium, potassium, and water excretion.

C) This choice is incorrect because loop diuretics are more likely to cause hypokalemia (low potassium levels) rather than hyperkalemia (high potassium levels). Loop diuretics can increase potassium excretion, leading to a potential deficiency.

D) This choice is correct. Loop diuretics are potent potassium-wasting diuretics, meaning they increase potassium excretion in the urine, potentially causing hypokalemia. The nurse should closely monitor the client's potassium levels and provide potassium supplementation if necessary.

Correct Answer is C

Explanation

A) This choice is incorrect because serum sodium levels are not directly impacted by digoxin. However, electrolyte imbalances, including hypokalemia, can potentiate digoxin toxicity, so potassium levels should be monitored.

B) This choice is incorrect because while digoxin can impact liver function, it is not the primary parameter to be monitored. Liver function tests may be performed periodically to assess liver health during digoxin therapy.

C) This choice is correct. Digoxin is a cardiac glycoside that can impact renal function. Monitoring urine output is essential to assess kidney function and the client's response to the medication.

D) This choice is incorrect because blood glucose levels are not specifically impacted by digoxin. However, hypokalemia resulting from digoxin therapy can cause alterations in glucose metabolism, so blood glucose levels should be monitored in clients taking digoxin.

A. Limit fluid intake to prevent fluid overload. B. Avoid foods high in potassium while on this medication. C. Take the medication in the morning to promote sleep. D. Monitor blood pressure daily and adjust the dose accordingly.

Correct Answer is B

Explanation

A) This choice is incorrect because limiting fluid intake is not specific to the administration of spironolactone. Fluid intake may need to be adjusted based on the client's overall fluid balance and congestive heart failure status, but it is not a direct instruction related to the medication.

B) This choice is correct. Spironolactone is a potassium-sparing diuretic that can cause hyperkalemia (high potassium levels). The client should avoid foods high in potassium to help prevent potassium overload and potential adverse effects.

C) This choice is incorrect because the timing of spironolactone administration may vary depending on the client's individual response and the presence of other medications. The client should follow the prescribed schedule given by the healthcare provider.

D) This choice is incorrect because monitoring blood pressure daily and adjusting the dose accordingly is not specific to the administration of spironolactone. While blood pressure may need to be monitored regularly, dosage adjustments should only be made under the guidance of the healthcare provider.
