Correct answer: C — Renal function and serum gentamicin concentrations
Gentamicin has nephrotoxicity and ototoxicity risks and requires therapeutic drug monitoring. Renal function affects dosing and accumulation risk. In this scenario, the correct option is renal function and serum gentamicin concentrations. The other options are plausible but do not address the key clinical, legal or safety issue as directly. This aligns with UK pharmacy practice guidance cited in the reference field.
