For a patient on methotrexate and Humira, which lab value is most important to monitor for drug safety?
Show answer and explanation
Correct answer: A. Creatinine (renal function)
- A. Correct. Methotrexate is renally excreted; impaired renal function raises toxicity risk, so creatinine (with LFTs and CBC) is monitored.
- B. Sodium is not a primary methotrexate-monitoring parameter.
- C. Calcium is unrelated to methotrexate safety monitoring.
- D. Uric acid is not the key monitored value for these drugs.
