Carbamazepine has a boxed warning for which adverse effect?

A. Offer the client fluids with meals. Offering fluids with meals may decrease the client's appetite by creating a sense of fullness, which could further reduce calorie intake and not aid in weight gain.

B. Increase fiber in the client's diet. While fiber is important for digestive health, it may also contribute to a feeling of fullness and might not directly help in increasing body weight in clients with anorexia.

C. Encourage the client to eat less protein. Protein is essential for maintaining muscle mass and overall health, especially in clients with AIDS. Reducing protein intake would not be beneficial for weight gain or health maintenance.

D. Provide supplemental vitamins and supplemental nutrition. Offering supplemental nutrition and vitamins can help increase caloric intake and ensure that the client receives essential nutrients to support weight gain and overall health. This is the most appropriate action to help increase the client's body weight.

A. drowsiness: Drowsiness is a common side effect of many antianxiety medications, especially benzodiazepines. This can impair the client’s ability to safely drive or perform tasks requiring alertness, making this the most appropriate choice.

B. confusion: While confusion can occur with some antianxiety drugs, it is less common than drowsiness and typically occurs at higher doses or with prolonged use.

C. behavior changes: Behavior changes can occur but are less common and are not the primary reason for caution with activities requiring mental alertness.

D. sleep disorders: Sleep disorders are not a typical side effect of antianxiety medications; in fact, these drugs are often used to treat sleep disturbances.
