USPA Skydiving B License Practice test

Hypoxia, which occurs at high altitudes due to reduced oxygen availability, can lead to several physiological and psychological symptoms. Among these, light-headedness and impaired judgment are particularly notable. As the body struggles to get enough oxygen, the brain is affected, which can result in confusion and a diminished ability to make sound decisions. This can pose significant risks for skydivers, as impaired judgment can hinder their ability to react appropriately during a jump or in response to an emergency.

The other choices reflect misconceptions about hypoxia. For instance, the idea of increased physical strength and endurance does not hold true; rather, performance typically declines in hypoxic conditions. Similarly, enhanced clarity of thought and improved coordination are contrary to the effects of oxygen deprivation. Under hypoxic conditions, cognitive functions and motor skills are generally diminished, further stressing the importance of recognizing and responding to the symptoms of hypoxia effectively.
