Which term describes severe tissue death due to lack of blood supply?

• A. Edema
• B. Cholecystectomy
• C. Necrosis
• D. Analgesia

Answer: (C)

Severe tissue death due to loss of blood supply is necrosis. When blood flow is blocked or significantly reduced, cells are starved of oxygen and nutrients and die, leading to nonfunctional, often discolored tissue that can break down and become prone to infection. This differs from edema, which is swelling from fluid buildup, analgesia, which is pain relief, and cholecystectomy, which is surgical removal of the gallbladder. In patient care, recognizing necrosis helps guide decisions about cleaning, protection, and pursuing interventions to prevent further damage.
