Which supplements are recommended with a high-protein, high-calorie diet for immobile patients?

• A. Vitamin D and calcium
• B. Vitamin B and C
• C. Iron and zinc
• D. Vitamin K

Answer: (B)

When a patient is on a high-protein, high-calorie diet, the body needs vitamins that help turn that protein into usable energy and support tissue repair. B vitamins act as coenzymes in energy metabolism, helping the body efficiently convert amino acids into energy and new tissue. Vitamin C is essential for collagen synthesis, wound healing, and immune defense, which is especially important for immobile patients at risk for pressure injuries. While the other vitamin and mineral options have important roles (bone health with D and calcium, clotting with vitamin K, or oxygen transport and immune support with iron and zinc), they’re not as directly tied to optimizing protein use and tissue repair in this scenario. So vitamins B and C best support the goals of a high-protein, high-calorie plan for immobile patients.
