## Question

A client 12 hours after thyroidectomy reports tingling around the mouth and muscle cramps. Which complication should the nurse suspect?

## Option

1. Hyperglycemia.
2. Fluid volume overload.
3. Hypocalcemia from parathyroid injury. **✔ Correct answer**
4. Expected postoperative anxiety only.

**Correct answer: 3**

## Explanation

Perioral tingling and muscle cramps after thyroidectomy suggest hypocalcemia, which can occur if the parathyroid glands are affected. This can progress to tetany or airway risk. The findings should not be dismissed as anxiety only.

## In-depth explanation

Clinical Judgment
Use the client cues, timing, labs, and safety risks to select the response that best fits Post-thyroidectomy hypocalcemia.

Memory Tip
Match the strongest cue cluster to the safest nursing judgment.

KR vs US
NCLEX items reward cue-based priority thinking rather than isolated recall.

## Clinical scenario

Clinical Practice Guide
For Post-thyroidectomy hypocalcemia, compare the complete cue pattern with the client's current stability, ordered data, and expected nursing scope.

Caution
Do not choose an action from one isolated cue when the full scenario changes priority or safety.

## Key concepts

- **Thyroidectomy** — Surgical removal of part or all of the thyroid gland.
- **Hypocalcemia** — A low calcium level that can cause tingling, cramps, or tetany.
- **Parathyroid Glands** — Small glands that help regulate calcium balance.
