A client with acute renal failure is prescribed loop diuretics to manage fluid overload. What is the nurse's responsibility when administering loop diuretics?

A. Incorrect. Fasting is not typically required before a renal nuclear scan.

B. Incorrect. The renal nuclear scan does not directly measure the glomerular filtration rate (GFR), which is typically assessed through blood tests.

C. Incorrect. A renal nuclear scan does not involve inserting a catheter into the bladder to obtain a urine sample.

D. Correct. A renal nuclear scan, also known as a renal scintigraphy, involves injecting a small amount of radioactive material intravenously. The radioactive material is taken up by the kidneys, and the scan creates images that assess kidney function and blood flow.

QUESTIONS

A. Correct. Loop diuretics can cause potassium loss and potentially lead to hypokalemia. The nurse should monitor the client's serum potassium levels frequently to assess for any imbalances.

B. Incorrect. While loop diuretics can be given intravenously for rapid action, the administration route depends on the client's condition and the healthcare provider's order.

C. Incorrect. Loop diuretics are used to promote diuresis and fluid removal from the body. Encouraging fluid restriction while on diuretic therapy may exacerbate dehydration and electrolyte imbalances.

D. Incorrect. The timing of loop diuretic administration is determined by the healthcare provider's order and the client's specific needs. Taking diuretics at bedtime may result in increased nighttime urination and sleep disruption.
