Choice C reason: Allowing the child to make choices can provide a sense of control, which is important for reducing stress during medical procedures⁷.

A. Hypoventilation B. Tachypnea C. Nonproductive cough D. Nasal stuffiness

Correct Answer is B

Explanation

Choice A reason: Hypoventilation is a late sign of hypoxemia and is characterized by an abnormally slow breathing rate, reducing oxygen intake and increasing carbon dioxide in the blood.

Choice B reason: Tachypnea, or rapid breathing, is an early sign of hypoxemia as the body attempts to increase oxygen levels by breathing more quickly.

Choice C reason: A nonproductive cough is not directly related to hypoxemia, which is a deficiency in the amount of oxygen reaching the tissues.

Choice D reason: Nasal stuffiness is not a specific indicator of hypoxemia and can be associated with various conditions.
