While changing a female newborn's diaper, the nurse observes a mucus-like, slightly bloody vaginal discharge. Which action would the nurse do next?

Choice A rationale The presence of a mucus-like, slightly bloody vaginal discharge, sometimes called pseudomenstruation, in a female newborn is a physiological phenomenon. This discharge is caused by the sudden withdrawal of maternal hormones, specifically estrogens, that crossed the placenta during the third trimester. It is a temporary, benign finding and the appropriate action is to document it as normal. Choice B rationale Notifying the primary care provider immediately is unnecessary as this finding is a well-recognized and expected hormonal effect in female newborns due to maternal estrogen withdrawal. Immediate notification would be warranted only if the bleeding was excessive, persistent, foul-smelling, or accompanied by other signs of illness or trauma. Choice C rationale Obtaining a culture of the discharge is not routinely indicated because the discharge is known to be physiological and not infectious in origin. A culture would only be necessary if the discharge was purulent, malodorous, or if the newborn showed systemic signs of infection, such as fever or lethargy. Choice D rationale While engorgement (swelling) of the breasts in newborns, regardless of sex, is another common finding related to maternal hormone transfer, it is a separate and distinct physical finding from the vaginal discharge. Inspecting for engorgement would not be the direct action needed to manage or assess the observed vaginal bleeding.
