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.

Correct Answer is C
Explanation
Choice A reason:
Calling the surgeon to talk to the patient may be helpful in some cases, but it does not directly address the patient's immediate emotional needs. The surgeon can provide detailed information about the procedure, which might alleviate some fears, but this is not always the immediate solution.
Choice B reason:
Offering to call the chaplain for the patient could provide emotional and spiritual support, which is important in holistic care. However, this should be done in addition to addressing the patient's concerns about the surgery itself.
Choice C reason:
Informing the patient that the survival rate for this surgery is very high directly addresses the patient's fear about not surviving the surgery. Providing factual reassurance about the success rate can help to alleviate anxiety and is an appropriate immediate response.
Choice D reason:
Recommending analgesics only during surgery does not address the patient's expressed fear and is not an appropriate response to the emotional concern. Analgesics are for pain management and do not provide reassurance about the outcome of the surgery.
Correct Answer is A
Explanation
Choice A reason: This response is calming and supportive. It addresses Mr. L's immediate distress by providing reassurance and a directive that can help him manage his panic, which is essential in a situation where a patient is experiencing extreme anxiety.
Choice B reason: While taking vital signs is an important step, it should not be the first response. The priority is to address the patient's acute distress and provide reassurance.
Choice C reason: This response minimizes the patient's feelings and does not address his immediate fear or offer any comfort or support.
Choice D reason: Asking why he thinks he's having a heart attack could increase his anxiety. It's important to first calm the patient before attempting to rationalize the situation.
