In which scenario is it appropriate to initiate a urinary catheter?

• A. Vaccinations
• B. Urinary catheter
• C. Perform surgery
• D. Prescribe antibiotics

Answer: (B)

Initiating a urinary catheter is appropriate whenever there is a clear need to drain the bladder or to measure urine output accurately. This is important for managing fluid balance, preventing urinary retention, and ensuring the bladder remains empty during procedures or in patients who cannot void normally. Vaccinations and prescribing antibiotics do not involve bladder drainage, so they don’t require catheter initiation. While surgery often involves catheter use to monitor urine output and keep the bladder empty, the core reason to start a catheter is the need to manage urine flow and output, which is why the scenario described by using a urinary catheter is the appropriate choice.
