What would be the primary focus of interventions for a client who sleepwalks?

A. The client's daughter, who is the primary caregiver: While the daughter may be involved in the client's care and decision-making process, the client themselves should provide informed consent if they have decision-making capacity. Informed consent cannot be provided by a caregiver unless legally authorized to do so.

B. The client: The client is alert, oriented, and has advance directives. In this scenario, the client possesses decision-making capacity and is capable of providing informed consent for the procedure. As long as the client is competent and able to understand the nature, risks, benefits, and alternatives of the procedure, they are the appropriate person to sign the informed consent document.

C. The client's partner: Unless legally designated as the client's healthcare proxy or legally authorized to provide consent on the client's behalf, the partner should not sign the informed consent document. The client themselves should provide consent if they have decision-making capacity.

D. The client's son, who has a durable power of attorney: While a durable power of attorney grants legal authority to make healthcare decisions on behalf of the client if they lack decision-making capacity, it does not negate the client's ability to provide informed consent if they are competent to do so. If the client is alert, oriented, and capable of understanding the procedure, they should sign the informed consent document themselves.

A) Headache:
Clients with obstructive sleep apnea often experience morning headaches due to the intermittent hypoxia and hypercapnia that occur during episodes of apnea. These headaches are typically described as dull and diffuse and may improve throughout the day.

B) Nausea:
While gastrointestinal symptoms such as nausea can occur in some individuals with sleep apnea, it is not a typical or specific finding associated with this condition. Nausea may result from other causes, such as medication side effects or underlying gastrointestinal issues, rather than directly from obstructive sleep apnea.

C) Hypotension:
Obstructive sleep apnea is more commonly associated with hypertension rather than hypotension. The recurrent episodes of hypoxemia and sympathetic nervous system activation during apneic episodes can lead to systemic hypertension over time.

D) Constipation:
Constipation is not a typical finding associated with obstructive sleep apnea. While sleep apnea may contribute to fatigue and alterations in gastrointestinal motility in some individuals, constipation is not a direct consequence of this sleep disorder.
