## Question

Complete the safety plan for a 9-year-old taking desmopressin at bedtime for primary nocturnal enuresis.

Minimize fluid intake beginning ::선택::1 hour4 hours8 hours24 hours before the bedtime dose and continue until morning or at least ::선택::2 hours4 hours8 hours16 hours after the dose. During recurrent vomiting or diarrhea, ::선택::doublecontinue unchangedinterruptcrush twice the medication and contact the prescriber.

## Explanation

Fluid intake should be minimized from 1 hour before desmopressin until the next morning or for at least 8 hours. Treatment should be interrupted during vomiting or diarrhea, and headache with confusion can signal hyponatremia.

## In-depth explanation

Quick answer
Prevent desmopressin-related water intoxication and hyponatremia.

Why this is correct
Desmopressin is a potent antidiuretic. Illness, heat, vigorous exercise, or excess drinking can convert routine use into dangerous free-water retention.

Easy analogy or mental picture
Use a family-centered medication-safety loop: verify age or pregnancy context, identify the exposure and new cue, prevent further harm, stabilize the client, and confirm the response.

Memory hook
Population, indication, dose or route, contraindication, urgent cue, protective action, and reassessment.

NCLEX decision rule
Choose the action that protects the maternal, newborn, or pediatric client from the most immediate medication-related harm while preserving authorized treatment.

Why the other choices are wrong
Options that normalize a danger sign, substitute an unapproved route or dose, or delay reassessment leave the client exposed to preventable harm.References

## Clinical scenario

Maternal, newborn, and pediatric medication safety review
Verify the client's age or pregnancy stage, indication, weight or laboratory context, route, interacting therapies, contraindications, caregiver teaching, and measurable follow-up.
