Hypoxia is defined as what?

• A. Not enough oxygen for metabolic needs
• B. Excess oxygen in tissues
• C. Oxygen saturation above 100%
• D. Normal oxygen delivery

Answer: (A)

The main idea here is that hypoxia means tissues aren’t getting enough oxygen to meet their metabolic needs. It’s about tissue oxygenation, not just the amount of oxygen in the blood. When delivery to tissues is insufficient or cells can’t use oxygen properly, metabolism suffers and symptoms can worsen. So the correct description is that there isn’t enough oxygen for metabolic needs. Hyperoxia would be too much oxygen in tissues, which isn’t what hypoxia describes. An oxygen saturation reading above 100% isn’t physiologically possible, and normal oxygen delivery means oxygen is being supplied adequately, not hypoxic.
