What factors could contribute to mastitis in a breastfeeding mother? (Select all that apply.)

Choice A rationale
Atelectasis, or collapse of part or all of a lung, is a potential complication of respiratory distress syndrome in neonates. However, it would not typically cause symptoms such as increased feeding without weight gain, abdominal distention, and vomiting.
Choice B rationale
Congenital cardiac disease could potentially cause symptoms such as increased feeding without weight gain, but it would not typically cause abdominal distention and vomiting. Furthermore, congenital cardiac disease would likely have been detected prior to the onset of respiratory distress syndrome.
Choice C rationale
Necrotizing enterocolitis is a serious intestinal condition that can occur in premature infants, particularly those with respiratory distress syndrome. Symptoms can include increased feeding without weight gain, abdominal distention, and vomiting.

Choice D rationale
An allergy to infant formula could potentially cause symptoms such as increased feeding without weight gain, abdominal distention, and vomiting. However, this would not typically be associated with respiratory distress syndrome. .

Choice A rationale
Hypothermia is not a typical response to phototherapy in an isolette. The heat from the phototherapy lights would typically prevent hypothermia.
Choice B rationale
Bradycardia, or a slow heart rate, is not a typical response to phototherapy in an isolette. If bradycardia occurs, it could be a sign of a serious condition that needs immediate medical attention.
Choice C rationale
Dehydration is a possible response to phototherapy in an isolette. The lights used in phototherapy can cause an infant to lose more water through their skin, leading to dehydration.
Choice D rationale
Decreased muscle tone is not a typical response to phototherapy in an isolette. If decreased muscle tone is observed, it could be a sign of a serious condition that needs immediate medical attention.
