You are waiting for a mountain climber to be brought down from an altitude of 10,000 feet after he had an acute decline in his level of consciousness. A report from a wilderness first responder tells you that the patient had been experiencing worsening shortness of breath, had been coughing heavily, and said that he felt like he had no energy. According to the wilderness first responder, the patient's respiratory rate declined from 36 to 10 breaths/min when the patient's level of consciousness decreased from awake to responsive to painful stimuli. The first responder is treating the patient for high-altitude pulmonary edema. You suspect that this condition has resulted in:
A) c. Respiratory failure
B) b. Respiratory arrest
C) a. High-altitude cerebral edema
D) d. Severe respiratory distress
Answer: C) a. High-altitude cerebral edema
