## Question

A client with anorexia nervosa is admitted with dizziness, heart rate 44/min, and potassium 2.8 mEq/L. Which concern is the priority?

## Option

1. Selecting a preferred meal tray
2. Encouraging group recreation immediately
3. Discussing long-term career goals
4. Risk for cardiac dysrhythmia from electrolyte imbalance **✔ Correct answer**

**Correct answer: 4**

## Explanation

Severe bradycardia and hypokalemia in anorexia nervosa create immediate risk for cardiac dysrhythmia. Physiologic stabilization is the priority before long-term psychosocial goals. Nutrition planning is important but must occur with medical safety monitoring.

## In-depth explanation

Clinical Judgment
Eating disorder care begins with medical stability when vital signs and electrolytes are dangerous.

Memory Tip
Low potassium plus bradycardia: protect the heart.

## Clinical scenario

Clinical Practice Guide
Anorexia nervosa hospitalization focuses on cardiac monitoring, electrolytes, nutrition rehabilitation, refeeding risk, and psychiatric care.

Caution
Refeeding must be monitored because electrolyte shifts can be dangerous.
