In providing care for clients, the nurse knows that the normal stimulus to breathe is a/an:
Correct Answer: C
Rationale: The correct answer is C: increased carbon dioxide level. When carbon dioxide levels rise in the body, it triggers the respiratory center in the brain to increase the rate and depth of breathing, known as the hypercapnic drive. This mechanism helps maintain the body's acid-base balance and ensures adequate gas exchange. Increased oxygen level (
A) does not directly stimulate breathing, as oxygen is primarily sensed by peripheral chemoreceptors. Decreased carbon dioxide level (
B) can lead to hypoventilation rather than increased ventilation. Decreased oxygen level (
D) can trigger the hypoxic drive to breathe, but it is not the primary stimulus under normal conditions.
