How can a nurse tell if a mother is correctly bathing a newborn?

The correct choice highlights an important practice in caring for newborns. By uncovering only the body part being washed, the mother effectively maintains the infant's warmth and comfort during bathing. Newborns are sensitive to temperature changes, and exposing only the part being cleaned helps prevent them from becoming cold, which is crucial for their overall well-being.

Additionally, this approach can foster a sense of safety and security for the infant, as they are not fully exposed during the bathing process. It's essential for caregivers to prioritize the infant's comfort and safety, making this practice beneficial for both the newborn's physical health and emotional security. This method is contrasted with other choices that may either compromise the baby's comfort or are not recommended practices during bathing.
