**Question:** Bedsore is an example of which of the following type of ulcer?

A. Pressure ulcer
B. Chemical ulcer
C. Hemostatic ulcer
D. Infective ulcer

**Correct Answer:** A. Pressure ulcer

**Core Concept:** Bedsore, also known as pressure ulcer, is a type of ulcer that occurs due to long-term pressure on the skin and underlying tissues. This pressure interferes with blood flow to the affected area, leading to tissue ischemia and subsequent necrosis.

**Why the Correct Answer is Right:** A pressure ulcer occurs when prolonged pressure is applied to bony prominences or other areas of the body, such as the hips, heels, elbows, and sacrum. The prolonged pressure results in ischaemia and tissue necrosis. The correct answer is "A. Pressure ulcer" because this type of ulcer is directly related to the pressure-induced damage to the skin and underlying tissues.

**Why Each Wrong Option is Incorrect:**

B. Chemical ulcer: This option refers to an ulcer caused by chemical agents, such as alkalis or acids, which can damage the skin and underlying tissues. Chemical ulcers are not related to prolonged pressure.

C. Hemostatic ulcer: A hemostatic ulcer refers to an ulcer resulting from the process of blood clotting, which is unrelated to prolonged pressure.

D. Infective ulcer: An infective ulcer is caused by infection, not prolonged pressure. Infective ulcers may co-occur with pressure ulcers, but they are not the primary cause.

**Clinical Pearl:** Recognizing and managing pressure ulcers is crucial for patient care, especially for those with limited mobility or at risk due to impaired circulation or compromised skin integrity. Early detection and intervention can prevent progression of the ulcer and improve patient outcomes.
