Explanation: According to the Munro Pressure Risk Assessment Scale, a 25% weight loss in the previous 30 days or a 210% weight loss in the previous 180 days poses the greatest risk for pressure ulcer development. This significant weight loss indicates malnutrition and increased vulnerability to pressure ulcers. Malnutrition compromises tissue integrity and impairs the body's ability to heal, making the patient more susceptible to pressure ulcers. Monitoring and addressing nutritional needs are crucial in preventing pressure ulcers in surgical patients. Options A, C, and D do not specifically indicate a high risk for
