Final answer:
If a mother is napping and wants the nurse to attend to her infant, the best course of action would be to request the nurse to care for the infant without waking her.
Step-by-step explanation:
If a mother is napping and wants the nurse to attend to her infant, the best course of action would be to request the nurse to care for the infant without waking her. This allows the mother to continue resting while ensuring that the infant is well taken care of. Waking up the father or discontinuing the nap and attending to the infant herself may not be ideal if the mother needs rest.
