Correct Answer is D

Explanation

A. Disturbed body image related to depression: While body image disturbances can occur with depression, it is not the primary concern following a suicide attempt.

B. Imbalanced nutrition: Less than body requirements related to depression: While nutritional imbalances may be present in clients with depression, the most pressing concern after a suicide attempt is safety.

C. Hygiene self-care deficit related to depression: A self-care deficit is often present in depression but is not the most urgent diagnosis after a suicide attempt.

D. Risk for self-directed violence related to depression: This is the most appropriate nursing diagnosis following a suicide attempt, as it directly addresses the client’s risk of harm to themselves.

A. Offer the client fluids with meals. B. Increase fiber in the client's diet. C. Encourage the client to eat less protein. D. Provide supplemental vitamins and supplemental nutrition.

Correct Answer is D

Explanation

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.
