Final answer:
The nurse should recommend against the use of powder on babies due to the risk of inhalation and potential harm to the infant's respiratory system. Maintaining clean and dry skin is typically adequate for baby hygiene.
Step-by-step explanation:
Responding to the question, the correct advice from a nurse concerning the use of powder on a baby's skin should be option 2: "It is recommended that powder not be put on babies." This is due to the potential risk of inhalation, which can lead to respiratory problems, and because some powders contain small particles that can be harmful if inhaled. Instead, keeping the baby's skin clean and dry is generally sufficient for good hygiene. If a parent is concerned about diaper rash, they should consult with the child's paediatrician for recommended products that are safe for use on sensitive baby skin.
