A burn patient's skin barrier is compromised, leading to increased risk. Which mechanism explains why bacterial infection becomes more likely?

💡 Explanation

Bacterial infection risk increases because the stratum corneum, the primary skin barrier, is damaged in burns, therefore allowing pathogens to easily penetrate. Rather than other mechanisms, the physical disruption of the skin's outer layer provides direct access.

• A patient with arthritis takes a COX-2 selective inhibitor. Why does this drug regimen reduce inflammation and pain?
• If an asthmatic patient's inhaled corticosteroid dosage is insufficient to prevent mast cell degranulation triggered by allergen exposure, which consequence follows regarding histamine?
• A patient develops localized swelling in the lower leg after prolonged standing. Why does compression therapy via specialized socks reduce this edema?
• Following a benzene exposure incident in a chemical plant, a worker develops aplastic anemia. Which mechanism explains why red blood cell transfusions alone cannot fully resolve his fatigue?
• An individual with chronic ethanol consumption exhibits significantly reduced gluconeogenesis. Which mechanism explains why this phenomenon occurs in the liver?
• Which outcome occurs when baroreceptor firing decreases and pressure is quickly ramped through static sealing in the haptic perception mechanism?
