Psychiatry · Child and adolescent psychiatry: desmopressin for short-term cover

Sample item

A 10-year-old with primary nocturnal enuresis responds slowly to an alarm. He is going to a school camp in three days and wants dry nights for the trip. Which treatment gives rapid short-term benefit?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Desmopressin

Desmopressin reduces night-time urine volume within days and is useful for short-term cover such as camps or sleepovers. The alarm has a higher long-term cure rate but works slowly.

Option by option

  • A. Continuing the alarm alone

    The alarm works over weeks and would not give cover in three days.

  • B. Desmopressin (correct)

    Correct. It acts quickly and suits short-term cover.

  • C. Imipramine

    Imipramine has cardiac toxicity risk and is not preferred for short-term cover.

  • D. Oxybutynin

    Oxybutynin is used for daytime urgency and detrusor overactivity.
