The nurse seeks to assess the renal function of an elderly client who is about to receive a nephrotoxic medication. Which of the following labs provides the best indicator for renal function?
Suggested Answer:D🗳️
Due to decreases in lean body mass, blood creatinine is not as good an indicator of the elderly clients renal function as creatinine clearance. Urinalysis and blood urea nitrogen reflect hydration status and other clues to health but are not specific for renal function. The electrolytes might be deranged in renal failure but are not a direct correlation to the kidneys capability to eliminate waste. Therefore, the best lab for renal function in the elderly is thought to be creatinine clearance, which is a widely used test for glomerular filtration rate. Safety and Infection Control
