David, a 30-year-old, comes to your unit for treatment of multiple broken bones following a car accident. He is friendly and flirtatious but very demanding. As you gather data from him, you learn that the police have been looking for him for petty theft. He laughs and says, "Like they don't have better things to do!" He states he has changed jobs three times in the past year and has just broken off his second engagement. His former fiancée is visiting and privately tells you that you need to be careful because "He doesn't always tell the truth." You suspect which of the following personality disorders?

Choice A reason: An illusion is a misinterpretation of a real external stimulus, which is not the case here as there is no snake.

Choice B reason: Attention-getting behavior is a possibility, but given that Mr. G is specifically referencing a snake that isn't there, it suggests a hallucination.

Choice C reason: A hallucination is a sensory perception in the absence of external stimuli, which fits Mr. G's description of seeing a snake that isn't there.

Choice D reason: A delusion is a firmly held false belief; while Mr. G may have this, the immediate experience he's describing is a hallucination, not a delusion.

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.
