B) High-altitude peripheral edema (HAPE)

C) High-altitude circulatory edema (HACE)

D) None of the above

2) At high altitudes, changes occur at all levels of the oxygen transport system including:

A) Ventilation

B) Pulmonary diffusion

C) Circulation and tissue diffusion

D) All the above

3) At sea level, the alveolar-arterial (A-a) gradient is:

A) 60 -117 mm Hg

B) 6 -17 mm Hg

C) 60 -170 mm Hg

D) None of the above

4) At high altitude in unacclimatized persons:

A) Appetite and caloric intake increase dramatically

B) Have distaste for sweets and prefer fats

C) Have fluid losses resulting from the insensible water losses associated with hyperventilation and low humidity, as well as diuresis induced by hypoxia and the cold environment

D) None of the above

5) Changes in the ECG after ascent to high altitude:

A) Right-axis deviation, right precordial T-wave inversion from a normally upright adult T wave

B) T-wave changes in the left precordial leads in mountaineers

C) Loss of normal circadian rhythm and QTc prolongation in both infants and adults

6) At high altitude, climbers with polycythemia:
