The nurse is completing an assessment on an older-adult patient who is having difficulty falling asleep. Which condition will the nurse further assess for in this patient?

Choice A reason: Depression is strongly linked to insomnia in older adults, causing difficulty falling asleep due to rumination, low mood, or altered sleep architecture. Assessing for depression is critical, as it may underlie the sleep disturbance, requiring targeted interventions like therapy or antidepressants to improve sleep and mental health. Choice B reason: Muscle fatigue may cause physical discomfort but is not a primary cause of difficulty falling asleep. It is more likely to affect sleep quality than initiation. Depression is a more common and significant contributor to insomnia in older adults, making this an incorrect choice. Choice C reason: Hypertension can be associated with sleep apnea but is not directly linked to difficulty falling asleep. It may result from poor sleep but is less likely the cause. Depression is a more prevalent cause of insomnia, making this a less relevant condition to assess. Choice D reason: Hypothyroidism can cause fatigue and sleepiness, not difficulty falling asleep. It is less commonly associated with insomnia compared to depression, which significantly disrupts sleep onset in older adults. This condition is less relevant to the patient’s presentation, making it incorrect.
