A nurse is caring for a school-age child who is taking valproic acid. The nurse should expect the provider to order which of the following diagnostic tests?

Jaundice.

Rationale:

• A. Weight loss is not a common or serious adverse effect of valproic acid. Valproic acid can cause weight gain, not weight loss.
• B. Jaundice is a sign of liver damage, which is a serious and potentially fatal adverse effect of valproic acid. Valproic acid can impair fatty acid metabolism and mitochondrial function, leading to hepatotoxicity and steatosis. The nurse should monitor the client's liver function tests and report any signs of jaundice, such as yellowing of the skin or eyes, dark urine, or clay-colored stools .
• C. Bradycardia is not a common or serious adverse effect of valproic acid. Valproic acid can cause cardiac arrhythmias, but they are usually tachycardic, not bradycardic.
• D. Polyuria is not a common or serious adverse effect of valproic acid. Valproic acid can cause hypernatremia and hypocalcemia, which can affect urine output, but polyuria is not a specific symptom of these electrolyte imbalances.

Choice A rationale:

Using isopropyl alcohol to clean hearing aids is not recommended. Isopropyl alcohol can damage the hearing aid components, especially the plastic parts. It is essential to use cleaning solutions specifically designed for hearing aids to avoid damaging them. Including this statement indicates a misunderstanding of proper hearing aid care.

Choice B rationale:

Replacing the batteries every 2 weeks is a standard recommendation for hearing aid users. Hearing aid batteries typically last 1 to 2 weeks, depending on usage. Regular battery replacement ensures the hearing aids continue to function optimally. This statement demonstrates an understanding of the basic care required for behind-the-ear hearing aids.

Choice C rationale:

Cleaning the ear with cotton swabs before inserting hearing aids is not advisable. Cotton swabs can push earwax further into the ear canal, leading to impaction. Excessive earwax can interfere with hearing aid function. Instead, clients should be encouraged to clean the outer parts of the hearing aids and avoid inserting any objects, including cotton swabs, into the ear canal.

Choice D rationale:

Disconnecting the battery when removing hearing aids is the correct practice. By disconnecting the battery, the client ensures that the hearing aids are turned off, preserving battery life and preventing unnecessary drainage. This statement indicates an understanding of proper hearing aid care and demonstrates the client's ability to maintain the device effectively.
