Which of the following are early signs of hypoxia?

The identification of early signs of hypoxia is crucial for prompt intervention and management of patients experiencing oxygen deprivation. The correct answer highlights symptoms such as restlessness, confusion, and an increased respiratory rate, which are indeed early indicators of hypoxia.

Restlessness often occurs because the brain is not receiving enough oxygen, prompting a state of agitation or anxiety. Confusion arises as cognitive function begins to decline due to inadequate oxygen supply to the brain. An increased respiratory rate is a physiological response to hypoxia, as the body attempts to compensate for low oxygen levels by increasing the rate of breathing to enhance oxygen intake.

These signs reflect the initial body responses to hypoxia before more severe complications develop. The other options describe symptoms that either indicate more advanced stages of hypoxia or are not directly related to the condition. Understanding these early indicators can help in recognizing hypoxia and initiating timely treatment to prevent detrimental outcomes.
