A client hospitalized for a myocardial infarction in a cardiac critica

A client hospitalized for a myocardial infarction in a cardiac critical care unit (CCU) is most like-ly to experience sleep deprivation as a result of:

1. A drug-disrupted circadian sleep pattern
2. Generally diminished cardiac output
3. Unfamiliar environmental stimuli
4. Increased emotional stressors

ANSWER

ANS: 3
Hospitalization, especially in intensive care units, makes clients particularly vulnerable to the ex-trinsic and circadian sleep disorders that cause the “ICU syndrome of sleep deprivation.” Con-stant environmental stimuli within the intensive care unit (ICU), such as strange noises from equipment, the frequent monitoring and care given by nurses, and ever-present lights, confuse clients and lead to sleep deprivation. Although the other options may be contributing factors, they are not as directly responsible.
