Which nursing intervention has the highest priority as a patient diagnosed with anorexia nervosa begins to gain weight?

A) Assess for depression and anxiety.
B) Observe for adverse effects of refeeding.
C) Communicate empathy for the patient's feelings.
D) Help the patient balance energy expenditures with caloric intake.

The nursing intervention of observing for adverse effects of refeeding most directly relates to weight gain and is a priority. Assessing for depression and anxiety, as well as communicating empathy, relates to coping. Helping the patient achieve balance between energy expenditure and caloric intake is an inappropriate intervention.
