What does dexamethasone do for Sandy Pittman?

• A. It prevents her from going into a state of delirium from altitude sickness.
• B. It speeds up oxygen absorption.
• C. It treats frostbite.
• D. It calms anxiety.

Answer: (A)

Dexamethasone helps prevent delirium from altitude sickness by reducing brain swelling caused by hypoxia at high altitudes. When the body is stressed by low oxygen, the brain can swell, leading to confusion and delirium. Dexamethasone stabilizes cells and lowers inflammation, which helps keep intracranial pressure from rising and protects mental status. That’s why it’s described as preventing delirium in Sandy Pittman’s altitude illness scenario. This medication doesn’t speed up how quickly oxygen is absorbed into the blood, so it won’t improve oxygen uptake. It also isn’t a treatment for frostbite, which is managed with warming and tissue protection rather than anti-inflammatory steroids. And it isn’t a drug to calm anxiety; while steroids can affect mood in some people, their primary purpose here is to limit brain swelling from altitude-related hypoxia.
