Explanation

A decreased need for sleep is a hallmark symptom and a core diagnostic criterion for a manic episode.
Individuals in a manic state often feel rested and energetic after sleeping for a very short duration, typically less than three hours per night.
This symptom is crucial for differentiating mania from other mood states, such as depression, where an increased need for sleep (hypersomnia) is more common.
The lack of sleep can exacerbate other manic symptoms like irritability, grandiosity, and poor judgment.

Option A: Increased need for sleep, or hypersomnia, is a symptom associated with depressive episodes, not mania. Mania is a high-energy state, which is inconsistent with needing more sleep.
Option C: Somnambulism, or sleepwalking, is a parasomnia that occurs during non-REM sleep. It is a separate sleep disorder and not a characteristic feature of mania.
Option D: While a manic episode does cause a disturbance in the sleep-wake cycle, this term is too broad and non-specific. The question asks for the 'characteristic' disturbance.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Clinical features of a manic episode, specifically related to sleep patterns as background academic context rather than a clinical decision trigger.
A nurse monitoring a patient with bipolar disorder must pay close attention to their sleep patterns. A sudden, significant decrease in sleep can be an early warning sign of an impending manic episode, allowing for early intervention.
Patient safety is a major concern. The lack of sleep associated with mania impairs judgment and increases impulsivity, heightening the risk of dangerous behaviors. Nurses must implement safety protocols for patients exhibiting these signs.
What if the patient reports feeling tired all the time and sleeping 12 hours a day? This would suggest a depressive episode, not mania. The nurse's assessment and intervention would shift focus from managing high energy and impulsivity to addressing low mood, anhedonia, and psychomotor retardation.

How to Approach the Question

First, identify the key concepts in the question: 'sleep pattern disturbance' and 'Mania'.
Recall the defining characteristics of a manic episode. Mania is a state of abnormally elevated energy, mood, and activity.
Logically connect the high-energy state of mania to sleep. A person with extremely high energy would likely require less sleep, not more. This helps you eliminate 'Increased need for sleep'.
Evaluate the remaining options for specificity. 'Decreased need for sleep' is a very specific symptom.
'Somnambulism' is a distinct sleep disorder (sleepwalking) and not a mood-related symptom.
'Sleep-wake cycle disturbance' is a very general term. While true, it's not as precise or characteristic as the decreased need for sleep. In nursing exams, always choose the most specific and accurate answer.
