Final answer:
The nurse assistant should assess the resident for hunger or discomfort and offer a light snack if necessary, ensuring the resident's well-being and comfort.
Step-by-step explanation:
When a resident wakes up during the night and asks for something to eat, the nurse assistant should assess the resident for signs of hunger or discomfort and provide them with a light snack if needed. It is important to address the needs of the resident professionally and with empathy, ensuring their comfort and well-being. Withholding food or ignoring the resident's request is not appropriate; they may have clinical or dietary requirements that necessitate a late-night snack, or they may be experiencing hypoglycemia or other conditions where eating is necessary.
