What is the primary cause of death in patients with severe burns?
Explanation & Rationale
Rationale: A. CAUTI (Catheter-Associated Urinary Tract Infection) is incorrect because, although burn patients often require indwelling urinary catheters for strict intake and output monitoring, CAUTIs are typically localized infections. They are rarely the direct cause of death and do not account for the high mortality seen in patients with severe burns. B. Sepsis is correct because it is the leading cause of death in patients with severe burns. Burn injuries destroy the skin, which is the body’s primary barrier against infection. This allows bacteria to easily enter the bloodstream. Additionally, burn patients experience immune system suppression and a massive inflammatory response, increasing the risk of systemic infection, septic shock, multiple organ dysfunction, and death. C. CLABSI (Central Line–Associated Bloodstream Infection) is incorrect because, while central lines are commonly used in burn patients and can lead to bloodstream infections, CLABSIs represent only one possible source of infection. They are not the most common overall cause of death compared with widespread sepsis from burn wounds. D. VAP (Ventilator-Associated Pneumonia) is incorrect because some burn patients require mechanical ventilation, especially those with inhalation injuries. Although VAP is a serious complication, it is less common than sepsis as the primary cause of mortality in severe burn patients.
