A nurse is caring for a toddler with difficulty sleeping during hospitalization. Which of the following actions should the nurse take to promote sleep?

A. Turn off the room light: Turning off all lights can sometimes increase anxiety in toddlers unfamiliar with their surroundings. A dim nightlight is often better to comfort them and reduce fear of the dark. B. Provide bedtime rituals: Bedtime routines like reading a book or singing help toddlers feel secure, especially in unfamiliar environments like hospitals. Consistency supports sleep readiness and reduces stress. C. Encourage play exercises in the evening: Stimulating activity before bed can delay sleep onset and make it harder for toddlers to settle down. Active play is best reserved for earlier in the day. D. Explain the source of the toddler's fears: Toddlers have limited cognitive understanding and may not be reassured by explanations. Comfort and routine are more effective for easing nighttime fears.
