Which of the following is an early sign of hypoxia?

• A. Tachycardia
• B. Restlessness and shallow breathing
• C. Weak pulse
• D. Persistent cough

Answer: (B)

Restlessness and shallow breathing are indicative of an early sign of hypoxia, which is a condition where there is a deficiency of oxygen in the tissues. When the body senses that it is not receiving enough oxygen, it can result in various symptoms as a way to signal distress. Restlessness, in particular, reflects the body's need for more oxygen and can be a psychological response, indicating that the patient may be uncomfortable or anxious due to insufficient oxygen levels. Shallow breathing may occur as a compensatory mechanism in an attempt to increase oxygen intake, though it is often ineffective in adequately addressing the hypoxic state. In contrast, tachycardia, or an increased heart rate, while also a potential indicator of hypoxia, tends to occur in later stages as the body attempts to deliver more oxygen to vital organs. A weak pulse represents a more advanced physiological response to insufficient oxygenation and can indicate significant compromise, while a persistent cough does not typically correlate directly with early hypoxia, as it may be associated more with respiratory or infection-related conditions rather than oxygen deficiency specifically. Therefore, restlessness and shallow breathing are more direct indicators of the body's immediate struggle with hypoxia.
