What is the best treatment for high-altitude cerebral edema (HACE)?

Immediate ascent to higher altitudes
Administration of oxygen and descent
Taking antipsychotic medication
Performing intense physical activity to increase oxygen uptake

The correct answer is: Administration of oxygen and descent

High-altitude cerebral edema (HACE) is a life-threatening condition caused by a lack of oxygen to the brain at high altitudes. Immediate ascent to higher altitudes would only worsen the condition, as the body needs time to acclimatize to changes in altitude. Taking antipsychotic medication would not be helpful as it is used to treat psychiatric disorders, not HACE. Performing intense physical activity would also be harmful as it would further increase the body's demand for oxygen at a time when oxygen supply is already limited. The best treatment for HACE is to administer oxygen and descend to a lower altitude, which allows the body to receive an adequate supply of oxygen and recover from the effects of being at a high altitude.
