NCLEX Question: Nursing Review

Nursing Students: Don’t miss the early warning signs of theophylline toxicity!

This med has a narrow therapeutic range (10–20 mcg/mL) - meaning even small increases can be dangerous.

Remember:

“Restless + Insomnia = Early Toxicity”

If left unchecked, this can progress to tachycardia, arrhythmias, and seizures — so always check your patient’s med levels and watch for any signs of toxicity
