Nursing Acceleration Challenge Exam (NACE) PN-RN Practice Test

To promote phase delay in circadian rhythm sleep disorder, a patient should avoid which of the following?

1. Bright light in the evening

2. Early morning light

3. Light after the body's minimum temperature

4. Sunlight after awakening

The correct answer is: Early morning light

To promote phase delay in circadian rhythm sleep disorder, it is essential for the patient to avoid bright light in the evening. Bright light exposure during the evening can signal the body to stay awake and alert, making it harder for the individual to shift their sleep-wake cycle to a later time. Early morning light, on the other hand, is beneficial to advance circadian rhythms, as it helps to cue the body's internal clock to wake up and become alert at the appropriate time. Light after the body's minimum temperature is also beneficial because it reinforces wakefulness when the circadian rhythm is naturally promoting alertness. Additionally, sunlight after awakening helps to synchronize the circadian rhythm with the external environment, which is vital for proper sleep regulation. Overall, avoiding bright light in the evening is crucial for promoting phase delay, as it allows the body to naturally drift toward a later sleep pattern without cues that would encourage wakefulness at nighttime.
