A. Heart rate 148/min – Correct. A heart rate of 148/min in a 3-year-old is elevated (tachycardia) and may indicate worsening dehydration or shock.

B. Potassium 3.9 mEq/L – Incorrect. This potassium level is within the normal range (3.5–5.0 mEq/L).

C. Respiratory rate 22/min – Incorrect. This is within the expected range for a 3-year-old.

A. Administer the medication subcutaneously. B. Initiate seizure precautions. C. Administer the medication with an antacid. D. Initiate contact precautions.

Correct Answer is B

Explanation

A. Administer the medication subcutaneously – Diazepam should be given orally or intravenously in severe cases, not subcutaneously.

B. Initiate seizure precautions – This is the correct answer. Alcohol withdrawal can lead to seizures due to central nervous system hyperactivity. Diazepam, a benzodiazepine, is used to prevent seizures and manage withdrawal symptoms.

C. Administer the medication with an antacid – There is no need to administer diazepam with an antacid; doing so can interfere with absorption.

D. Initiate contact precautions – Alcohol withdrawal is not an infectious condition, so contact precautions are unnecessary.
