PN ATI Capstone Maternal Newborn

Correct Answer: A

Rationale: Phototherapy is used to reduce bilirubin levels in newborns with jaundice. However, the intense light can cause damage to the newborn's corneas and retinas. The use of an eye mask protects the infant's eyes while allowing the therapy to proceed. Regular monitoring of the newborn's temperature and hydration status is also important, but the eye mask is a key protective measure.

Correct Answer: D

Rationale: Early decelerations are typically caused by head compression during contractions, which is a normal response and often indicates that the fetus is descending into the birth canal.

Correct Answer: A

Rationale: Cold stress in newborns can lead to increased oxygen consumption and energy expenditure as the body tries to maintain its temperature. This can result in hypoglycemia and metabolic acidosis if not addressed. The use of a radiant warmer helps maintain the infant's body temperature, reducing the risk of cold stress and its complications.

Correct Answer: C

Rationale: Raloxiphine (Evista) is a selective estrogen receptor modulator (SERM) used primarily to prevent and treat osteoporosis in postmenopausal women. It helps to maintain bone density and reduce the risk of fractures by mimicking the effects of estrogen on bone tissue. It is not indicated for the treatment of migraines, hypertension, or heart disease.

Correct Answer: D

Rationale: Repositioning the newborn every 2 to 3 hours during phototherapy is important to expose all areas of the skin to light and facilitate the breakdown of bilirubin.
