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.

Answer and Explanation

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 D

Explanation

Choice A reason: The theory that schizophrenia is primarily related to a disturbed mother-child relationship is outdated and not supported by current research.

Choice B reason: While prenatal factors may contribute to the risk, schizophrenia is not solely caused by brain damage from the mother's use of tranquilizers during pregnancy.

Choice C reason: Alterations in opioid receptors are not currently considered a primary cause of schizophrenia.

Choice D reason: Schizophrenia is considered a brain disorder, with current research focusing on a combination of genetic and environmental factors, brain chemistry, and structure.

A. "Relax. Take a few deep breaths. I'll stay with you." B. "I'll take your vital signs and call my supervisor." C. "Don't worry. She's done this many times before." D. "Why do you think you're having a heart attack, Mr. L?"

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.
