A client with COPD should receive only 1-2 liters per minute of oxygen, if needed, or they may lose their hypoxic drive. Which of the following statements is correct about hypoxic drive?
The client breathes only when their oxygen levels climb above a certain point.
The client breathes only when their carbon dioxide levels climb above a certain point.
The client doesn't notice they need to breathe.
The client breathes only when their oxygen levels dip below a certain point.
The Correct Answer is D
Choice A reason: This statement is incorrect because it suggests that higher oxygen levels trigger breathing, which is not the case in hypoxic drive.
Choice B reason: While carbon dioxide levels do influence breathing, this statement is not accurate in the context of hypoxic drive, which is specifically about oxygen levels.
Choice C reason: This choice is incorrect because the client does notice the need to breathe, but the trigger is low oxygen rather than high carbon dioxide levels.
Choice D reason: This is correct. In clients with COPD, chronic high levels of carbon dioxide can lead to a reliance on low oxygen levels to stimulate breathing.
