Certified Dietary Manager (CDM) 2025 – 400 Free Practice Questions to Pass the Exam

The term "pressure sore" specifically refers to lesions that develop on the skin and underlying tissue due to prolonged pressure, typically over bony areas of the body. These sores, also known as pressure ulcers or bedsores, occur when blood flow to a particular area is restricted, often due to immobility or prolonged sitting or lying in one position.

Understanding the mechanics of how pressure sores develop is key for dietary managers, especially when considering the nutritional needs of individuals at risk of developing these sores. Proper nutrition plays a critical role in skin integrity and healing processes.

The other options do not accurately describe pressure sores. Skin rashes can be a result of a variety of causes and are not directly related to pressure. Infections from cuts are injuries rather than pressure-related wounds, and enlarged lymph nodes are typically indicative of an immune response or infection elsewhere in the body. These distinctions highlight the specific nature of pressure sores as a clinical concern in patient care.
