A nurse is caring for a client who is preoperative for cataract removal.
Which of the following statements by the client indicates an understanding of the procedure?

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.

- A. Correct. The nurse should turn off the CPM machine during mealtime to allow the client to eat comfortably and prevent aspiration.

- B. Incorrect. The nurse should maintain the client's affected hip in a neutral position to prevent dislocation of the prosthesis and promote healing.

- C. Incorrect. The nurse should not instruct the client how to adjust the CPM settings for comfort, as this could interfere with the prescribed range of motion and speed of the device. The nurse should notify the provider if the client reports discomfort or pain.

- D. Incorrect. The nurse should not store the CPM machine under the client's bed when not in use, as this could pose a safety hazard and damage the device. The nurse should place the CPM machine on a stable surface away from the bed.
