The nurse is caring for a patient in the intensive care unit who is having trouble sleeping. The nurse explains the purpose of sleep and its benefits. Which information will the nurse include in the teaching session? (Select all that apply)
During NREM sleep, biological functions increase.
REM sleep decreases cortical activity.
Restful sleep preserves cardiac function.
NREM sleep contributes to body tissue restoration.
Sleep contributes to cognitive restoration.
Correct Answer : C,D,E
Choice A reason: During NREM sleep, biological functions like heart rate and metabolism decrease, not increase, to promote restoration. Increased functions occur in REM sleep or wakefulness. This statement is incorrect, as it misrepresents NREM sleep’s physiological role, making it an inappropriate teaching point.
Choice B reason: REM sleep increases cortical activity, supporting dreaming and memory processing, not decreasing it. This statement is inaccurate, as REM is characterized by high brain activity similar to wakefulness. It does not align with sleep’s benefits, making it incorrect for the teaching session.
Choice C reason: Restful sleep preserves cardiac function by reducing heart rate, blood pressure, and stress hormones, lowering cardiovascular strain. Adequate sleep prevents arrhythmias and hypertension, making this a correct teaching point to highlight sleep’s protective role in heart health for ICU patients.
Choice D reason: NREM sleep, especially deep stages, promotes body tissue restoration by facilitating protein synthesis and growth hormone release, aiding tissue repair. This is a key benefit, particularly for ICU patients recovering from illness, making it a correct point for the nurse’s teaching session.
Choice E reason: Sleep, particularly REM and deep NREM, supports cognitive restoration by consolidating memories and clearing brain metabolites. This enhances alertness and decision-making, critical for ICU patients’ recovery. This is a correct teaching point, emphasizing sleep’s role in mental clarity and function.

Correct Answer is C
Explanation
Choice A reason: Self-care deficit addresses physical inability to perform daily tasks, not psychological issues from sensory impairments. Hearing and visual loss primarily impact communication, leading to socialization issues. Assuming self-care deficit misaligns the diagnosis, risking neglect of psychological needs like social isolation, critical for mental health in sensory-impaired patients.
Choice B reason: Risk for falls is a physical safety concern due to sensory impairments but not psychological. Impaired socialization better addresses the psychological impact of communication barriers. Prioritizing falls risks overlooking social isolation, delaying interventions like communication aids, essential for mental well-being in patients with hearing and visual deficits.
Choice C reason: Impaired socialization, a psychological nursing diagnosis, reflects the communication barriers from hearing and visual impairments, leading to social isolation and emotional distress. This diagnosis guides interventions like assistive devices or support groups, critical for mental health, ensuring patients maintain social connections and emotional resilience despite sensory challenges.
Choice D reason: Impaired physical mobility relates to movement limitations, not psychological effects of sensory impairments. Hearing and visual loss primarily cause socialization issues, not mobility deficits. Assuming mobility misdirects care, neglecting psychological needs like social engagement, critical for preventing isolation and supporting mental health in sensory-impaired patients.
Correct Answer is A
Explanation
Choice A reason: Obstructive sleep apnea causes airway collapse, leading to hypopnea, apnea, and hypoxia. Assessing respiratory status, including oxygen saturation, respiratory rate, and snoring, is critical to detect life-threatening desaturations or respiratory failure. This priority ensures airway patency and adequate oxygenation, addressing the primary pathophysiology of the condition.
Choice B reason: Neurological function may be affected by hypoxia in severe sleep apnea, causing daytime sleepiness or cognitive issues. However, respiratory status is the priority, as airway obstruction directly threatens oxygenation. Neurological assessment is secondary, as it does not address the immediate risk of respiratory compromise.
Choice C reason: Circulatory status, like blood pressure, may be impacted by chronic sleep apnea due to hypoxia-induced hypertension. However, respiratory status takes precedence, as airway obstruction is the primary issue causing desaturation. Circulatory changes are secondary and less urgent than ensuring adequate ventilation.
Choice D reason: Gastrointestinal function is unrelated to obstructive sleep apnea’s primary effects. While reflux may contribute to sleep issues, it is not a priority compared to respiratory status, which
