What should be monitored during antibiotic therapy for a patient with renal impairment?

• A. Only the patient’s temperature
• B. Kidney function tests and signs of drug toxicity
• C. Patient's hydration status exclusively
• D. Heart rate and rhythm

Answer: (B)

During antibiotic therapy, particularly for a patient with renal impairment, it is essential to monitor kidney function tests and signs of drug toxicity. This is because many antibiotics are excreted through the kidneys, and renal impairment can lead to decreased clearance of these medications. As a result, the accumulation of antibiotics in the bloodstream can increase the risk of adverse effects or toxicity. Monitoring kidney function tests, such as serum creatinine and blood urea nitrogen (BUN), provides valuable insights into how well the kidneys are processing the drug. Additionally, watching for signs of toxicity—such as changes in renal function, unusual symptoms, or specific side effects related to the antibiotic being administered—ensures timely intervention if issues arise. Monitoring only the patient's temperature, hydration status, or heart rate and rhythm does not comprehensively address the specific concerns related to the renal impairment and antibiotic therapy. These factors, while relevant in a broader clinical context, do not focus on the implications of renal function on the pharmacokinetics and safety of antibiotic medications.
