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
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 B
Explanation
A. Rearrange furniture to clear walkways – While important for fall prevention, it does not directly address medication safety.
B. Use container lids of different shapes to indicate times of administration – Correct. Using distinct tactile markers helps clients with vision loss distinguish medications and adhere to their regimen.
C. Cover appliance cords with throw rugs – Incorrect. Throw rugs are a tripping hazard and should be removed, not used to cover cords.
D. Visit the client once per month to assess medication usage – Monthly visits may not be sufficient for ensuring medication adherence and safety.
Correct Answer is D
Explanation
A. Tachycardia – Digoxin toxicity typically causes bradycardia, not tachycardia, due to its effect on the AV node.
B. Hearing loss – Digoxin does not commonly cause hearing loss; ototoxicity is more associated with aminoglycoside antibiotics.
C. Insomnia – While some neurological symptoms may occur, insomnia is not a classic sign of digoxin toxicity.
D. Blurred vision – This is the correct answer. Digoxin toxicity can cause visual disturbances such as blurred vision, yellow-green halos, and scotomas. Other signs include nausea, vomiting, anorexia, fatigue, and cardiac arrhythmias.
