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 D

Explanation

A) This choice is incorrect because serum electrolyte levels are not directly measured during an echocardiogram. They are typically assessed through a blood test and are not specific to evaluating heart function using ultrasound.

B) This choice is incorrect because blood pressure readings are not directly measured during an echocardiogram. Blood pressure is typically assessed using a sphygmomanometer and is not specific to evaluating heart function using ultrasound.

C) This choice is incorrect because oxygen saturation levels are not directly measured during an echocardiogram. Oxygen saturation is typically assessed using a pulse oximeter and is not specific to evaluating heart function using ultrasound.

D) This choice is correct. Ejection fraction (EF) is a parameter measured during an echocardiogram to assess the client's heart function. It represents the percentage of blood pumped out of the heart's left ventricle with each heartbeat and is an essential indicator of heart muscle efficiency and potential heart failure.

Questions

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.
