Ryanair Initial Practice Exam

Which of the following best describes hypoxia?

1. A condition of excessive oxygen in the body

2. A physical condition from insufficient oxygen supply to tissues

3. A temporary state of dizziness

4. An allergic reaction to oxygen

The correct answer is: A physical condition from insufficient oxygen supply to tissues

Hypoxia is best described as a physical condition that arises from an insufficient oxygen supply to tissues. This definition encompasses the critical aspects of hypoxia, which include the inadequate delivery of oxygen to cells and organs, leading to a range of physiological effects. The body relies on an adequate oxygen supply to function properly, and when this supply is compromised, it can result in symptoms such as fatigue, confusion, and in severe cases, organ dysfunction or failure. The other options portray conditions that do not accurately reflect what hypoxia is. For instance, describing hypoxia as excessive oxygen in the body misrepresents the actual issue, which is a lack of oxygen. A temporary state of dizziness might occur as a symptom of hypoxia but does not encompass the broader and more serious implications of the condition. Lastly, an allergic reaction to oxygen is unrelated to hypoxia; the condition is not caused by an allergic response but rather by oxygen deficiency. Overall, option B succinctly captures the essence of hypoxia as a condition related to insufficient oxygen supply, making it the most accurate and comprehensive choice among the given options.
