A nurse is preparing to administer 0.5% Erythromycin ophthalmic ointment to a newborn. Which route and dose should the nurse apply?
Apply 1-2 cm ribbon from outer to inner canthus.
Apply 2-3 inch ribbon from inner to outer canthus.
Apply 1-2 cm ribbon from inner to outer canthus.
Apply 1-2 inch ribbon to upper eyelid.
The Correct Answer is C
Choice A rationale
Applying a 1-2 cm ribbon from outer to inner canthus is incorrect because it increases the risk of contamination and infection by moving from a less clean area to a more clean area.
Choice B rationale
Applying a 2-3 inch ribbon from inner to outer canthus is incorrect because the length of the ribbon is too long and the direction is not recommended for preventing contamination.
Choice C rationale
Applying a 1-2 cm ribbon from inner to outer canthus is correct as it minimizes the risk of contamination by moving from a cleaner area to a less clean area, ensuring proper application of the ointment.
Choice D rationale
Applying a 1-2 inch ribbon to the upper eyelid is incorrect because the upper eyelid is not the recommended site for application, and the length of the ribbon is too long.

Correct Answer is B
Explanation
Choice A rationale
Shivering is not a primary concern for newborns as they have limited ability to shiver. Instead, they rely on non-shivering thermogenesis to maintain body temperature.
Choice B rationale
Cold stress is a significant concern for newborns as it can lead to hypothermia, increased oxygen consumption, and metabolic acidosis. Placing a newborn under a radiant heat warmer helps maintain their body temperature and prevent cold stress.
Choice C rationale
Brown fat production is a natural process in newborns that helps generate heat. However, the primary purpose of using a radiant heat warmer is to prevent cold stress, not to stimulate brown fat production.
Choice D rationale
Basal metabolic rate reduction is not the primary concern. The focus is on preventing cold stress and maintaining the newborn’s body temperature.
