An older adult who reports taking a late afternoon nap every day to make up for disrupted sleep at night still feels tired. The nurse explains that:
a) Napping disrupts the circadian rhythm, leading to persistent fatigue.
b) Late afternoon naps are too short to provide restorative sleep.
c) Excessive napping during the day can exacerbate nighttime sleep disturbances.
d) Napping immediately after dinner is more effective for combating fatigue.
