Which of the following multidisciplinary care plans best integrates appropriate roles for a young adult hospitalized for severe anorexia with electrolyte disturbances?

Admit solely to a psychiatric ward and begin long-term group therapy without medical monitoring because starvation effects will self-correct once psychological therapy begins.

Immediate medical stabilization (IV fluids, electrolyte correction, cardiac monitoring) by medical team, daily nutrition plan and monitored refeeding by a registered dietitian to restore safe intake, and concurrent psychiatric evaluation with initiation of evidence-based psychotherapy and family involvement when appropriate.

Discharge after brief observation with instructions to increase caloric intake at home using internet diet plans and follow up with a general practitioner for medication if weight does not recover.

Refer only to a diet book program led by peer mentors on campus, because peer-led nutritional advice is both sufficient and preferable for medically severe anorexia with electrolyte problems.
