Practice Question
Before administering an antibiotic that can cause nephrotoxicity, which laboratory value is most important for the practical nurse (PN) to review?
Answer Choices:
Correct Answer:
Serum creatinine.
Rationale:
🔶 Serum creatinine is a key indicator of renal function, which is vital to assess before administering nephrotoxic antibiotics.
🔶 Nephrotoxic drugs such as aminoglycosides or vancomycin can worsen kidney function, especially if baseline creatinine is already elevated.
🔶 A high creatinine level suggests reduced glomerular filtration rate (GFR), meaning the kidneys may not clear the drug effectively.
🔶 Reviewing creatinine helps determine whether dose adjustments or alternative therapies are necessary.
🔶 Monitoring renal function prevents complications such as acute kidney injury, electrolyte imbalance, or drug accumulation.
