Which of the following is an example of altitude sickness?

• A. Acute Mountain Sickness
• B. High Altitude Pulmonary Edema
• C. High Altitude Cerebral Edema
• D. All of These Answers Are Correct

Answer: (D)

Altitude sickness covers the range of problems that can occur when you’re exposed to high altitude and the air is thin. The milder form, Acute Mountain Sickness, shows up with a headache, nausea, fatigue, and dizziness. More severe forms include High Altitude Pulmonary Edema, which is fluid buildup in the lungs causing shortness of breath, cough, and chest tightness, and High Altitude Cerebral Edema, which involves brain swelling with confusion, ataxia, and severe headache. Since all three are manifestations of altitude-related illness, they are all examples of altitude sickness. They reflect a progression from mild to life-threatening if not recognized and addressed through descent and supportive care.
