What assessment finding is typical in a male infant born at 28 weeks gestation?

In a male infant born at 28 weeks gestation, the typical assessment finding is flat areolae without palpable breast buds. At this stage of gestation, the fetal development of male breasts is not advanced enough for the presence of palpable breast tissue, which typically develops more significantly later in gestation. Therefore, the lack of developed breast buds is consistent with the developmental milestones you would expect at this early gestational age.

In contrast, the other options represent findings that are generally not associated with a 28-week gestation male infant. Testes being completely descended into the scrotum is uncommon as the descent of the testes usually occurs later, around 34-36 weeks. The presence of abundant lanugo is more expected in infants born before 28 weeks gestation, as full-term infants usually have less lanugo. Deep creases and peeling skin on the soles are typically seen in infants who are closer to term, as skin maturation and development continue as gestation progresses. Thus, the typical characteristics of a 28-week-old male infant align with the presence of flat areolae and absent breast tissue.
