Final answer:
A patient on valproic acid should report abdominal pain immediately to their healthcare provider, as it may indicate liver damage, a serious risk of valproic acid. Side effects like hair loss, weight gain, and ataxia are concerning but not immediately life-threatening.
Step-by-step explanation:
When taking valproic acid for seizures, it is crucial for a patient to be aware of potential side effects and to know which ones warrant immediate medical attention. Of the options provided, the client should report abdominal pain immediately to their healthcare provider as it may indicate a serious adverse effect such as hepatotoxicity (liver damage), which is a known risk of valproic acid. Other side effects such as hair loss, weight gain, and ataxia, while potentially concerning, are not typically immediate life-threatening conditions, but should still be discussed with a healthcare provider.
Considering the information about Patient B, their symptoms of weight loss, profuse sweating, increased heart rate, and difficulty sleeping are not directly related to the adverse effects of valproic acid, but they could speak to another condition, such as hyperthyroidism, and should be evaluated by a healthcare professional.
