A nurse is reviewing laboratory data for a client who has a new prescription for valproic acid. Which of the following baseline results should the nurse review prior to administering the first dose of the medication?

Potassium level

Thyroid function tests

Uric acid level

Liver function tests

Answer and Explanation

The Correct Answer is D

A. Potassium level – Valproic acid does not significantly affect potassium levels, so this is not a necessary baseline test.

B. Thyroid function tests – Valproic acid is not known to significantly impact thyroid function, making this an unnecessary test.

C. Uric acid level – Uric acid levels are more relevant for conditions like gout, and valproic acid does not typically cause hyperuricemia.

D. Liver function tests – This is the correct answer because valproic acid is metabolized in the liver and can cause hepatotoxicity. Baseline liver function tests (LFTs) should be reviewed before starting the medication to assess liver health.

Correct Answer is C

Explanation

A. Sore throat – A sore throat is expected following a tonsillectomy due to the surgical site trauma. It is not an immediate concern unless accompanied by other abnormal findings such as severe pain or difficulty breathing.

B. Blood-tinged mucus – Small amounts of blood-tinged mucus are normal after surgery. However, active bleeding would present as bright red blood rather than a small amount of tinged mucus.

C. Frequent swallowing – This is the priority finding because it may indicate active bleeding at the surgical site. Children may not always report bleeding but may swallow frequently as blood drips into their throat. If left undetected, excessive bleeding can lead to hemorrhage and airway compromise. The nurse should inspect the throat immediately and notify the provider.

D. Dark brown emesis – Vomiting old blood (which appears dark brown) may occur if the child swallowed some blood postoperatively. While this should be monitored, it is not as concerning as active bleeding, which presents as bright red blood.

A. Heart rate 148/min B. Potassium 3.9 mEq/L C. Respiratory rate 22/min D. Sodium 142 mEq/L

Correct Answer is A

Explanation

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.

D. Sodium 142 mEq/L – Incorrect. This sodium level is within the normal range (135–145 mEq/L).
