## Question

The nurse teaches a client who is starting levothyroxine. Which statement indicates correct understanding?

## Option

1. I will stop the medication when I feel less tired.
2. I will take it at bedtime with calcium supplements.
3. I will take it in the morning on an empty stomach. **✔ Correct answer**
4. I will double the dose if I miss one day.

**Correct answer: 3**

## Explanation

Levothyroxine is usually taken consistently in the morning on an empty stomach. It should not be stopped when symptoms improve, and calcium can interfere with absorption. Missed-dose instructions should follow provider or pharmacy guidance rather than doubling without direction.

## In-depth explanation

Clinical Judgment
Thyroid replacement is long-term and absorption-sensitive.

Memory Tip
Levothyroxine: empty stomach, same time.

## Clinical scenario

Clinical Practice Guide
Thyroid medication teaching includes consistent timing, monitoring symptoms and labs, and separating interacting supplements when directed.

Caution
Do not stop hormone replacement abruptly without guidance.
