## Question

A parent asks whether viscous lidocaine can be rubbed on the gums of a 10-month-old infant for teething pain. Which response is best?

## Option

1. Use a household spoon to apply a generous amount whenever the infant cries.
2. Add viscous lidocaine to each bottle so the gums stay numb during feeding.
3. Apply the medicine before sleep because swallowing it reduces systemic absorption.
4. Avoid viscous lidocaine for teething; use supervised non-drug comfort measures and seek guidance. **✔ Correct answer**

**Correct answer: 4**

## Explanation

Viscous lidocaine should not be used for teething in infants and young children because swallowing or excessive exposure can cause seizures, cardiopulmonary arrest, severe brain injury, and death.

## In-depth explanation

Quick answer
Keep viscous lidocaine away from infant teething care.

Why this is correct
Topical numbing can also impair protective oral sensation. Safer approaches include gentle gum massage and a firm, nonfrozen teether under supervision.

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.
