Question

Arrange the pressure sore frequency in descending order.

• A. [(A)] \textbf{Heel}
• B. [(B)] \textbf{Greater trochanter}
• C. [(C)] \textbf{Malleolus (lateral then medial)}
• D. [(D)] \textbf{Ischium}

Hint:

\textbf{Clinical Relevance: Pressure Ulcer Prevention.} Understanding the high-risk areas for pressure sore development is crucial for implementing preventive measures such as frequent repositioning of the patient, using pressure-redistributing surfaces, and meticulous skin care, especially in immobile or bedridden individuals.

Answer 1

The Correct Option is B

Pressure sores, also known as bedsores or pressure ulcers, occur due to prolonged pressure on the skin, often over bony prominences. The frequency of pressure sore development at different anatomical sites is influenced by factors such as the patient's position (supine, lateral, sitting), immobility, and underlying medical conditions. The descending order of frequency is generally observed as follows: Ischium (D): Common in sitting positions due to pressure on the ischial tuberosities. Greater trochanter (B): Frequent in the lateral decubitus position (lying on the side). Sacrum (E): Common in supine (lying on the back) and semi-recumbent positions. Heel (A): Frequent in supine position, especially with prolonged bed rest. Malleolus (C): Less frequent compared to the above sites but can occur in lateral or medial positions. Therefore, the correct descending order of pressure sore frequency is Ischium, Greater trochanter, Sacrum, Heel, and Malleolus.
