Answer:
b. Repositioning the patient on a scheduled basis
Step-by-step explanation:
Prophylactic antibiotics are not prescribed commonly to prevent pressure ulcers. Proactive dressings can't be applied unless skin is broken. Continuous nutrition is required but the most appropriate way is to reposition the patient to prevent pressure ulcers and ischemia. Pressure ulcers or pressure sores develop due to too much pressure on tissue causing tissue damage.
