Gentamicin Dose Calculation and Monitoring
A timed 10-minute pharmacology OSCE station with reading time, a warning bell and an examiner-style weighted checklist including critical items, marked the way a real examiner would mark it.

Candidate instructions
You are a foundation doctor on a medical ward. A 64-year-old male patient (75 kg) is admitted with a complicated urinary tract infection and suspected sepsis. His serum creatinine is 105 micromol/L and eGFR is 58 mL/min/1.73 m^2. You are asked to prescribe the initial once-daily dose of intravenous gentamicin and explain the level monitoring to the examiner. The examiner will role-play a nurse or colleague. You have 10 minutes. Calculate the dose, state the important safety considerations, and explain when and why serum gentamicin levels should be monitored.
How the station runs
- 60 seconds of reading time with the instructions above, and nothing else.
- 10 minutes on the clock, with a warning bell before the end.
- The examiner's checklist, 13 weighted items worth 24 marks, revealed only when the station ends.
- Your score, with a critical-fail flag if a safety-critical item was missed.
The checklist stays hidden until the station is over, exactly as it would outside the exam room.
