Final answer:
The nurse aide must ensure that hunger, thirst, and elimination needs are met for the client to rest comfortably.
Step-by-step explanation:
Before a client can rest comfortably, the nurse aide must ensure that hunger, thirst, and elimination needs are met. Giving the client a blanket can also contribute to their comfort. However, turning off all the lights or asking the nurse to give the client a sleeping pill is not necessary or appropriate for the nurse aide's role in ensuring the client's comfort.
