A nurse is assessing a newborn who has Erb-Duchenne palsy.
Which of the following findings should the nurse expect?

Choice A rationale

Soft grunting noises during expiration are a sign of mild to moderate respiratory distress in a newborn. Grunting is the newborn's attempt to keep the alveoli open by increasing Positive End-Expiratory Pressure (PEEP), suggesting decreased lung compliance or insufficient surfactant. This finding requires immediate notification of the provider for evaluation and potential intervention.

Choice B rationale

A positive Babinski reflex, which involves the great toe dorsiflexing and the other toes fanning out upon stroking the sole of the foot, is a normal neurological finding in a newborn and infant. This reflex persists until about 1 to 2 years of age as the central nervous system matures, and therefore does not require reporting.

Choice C rationale

Acrocyanosis, which is pale blue hands and feet with pinkish trunk and mucous membranes, is a common and normal finding in a newborn during the first 24 to 48 hours after birth due to immature peripheral circulation and cold exposure. This peripheral vasoconstriction resolves spontaneously and is not typically reported unless accompanied by central cyanosis.

Choice D rationale

Blood-tinged discharge from the vagina, often called pseudomenstruation, is a normal, transient finding in female newborns. It is caused by the withdrawal of maternal estrogen hormones following birth, leading to a minor sloughing of the uterine endometrium, and does not indicate a pathological condition requiring immediate reporting.

Choice A rationale

Newborns require substantial sleep for optimal growth and neurological development, often sleeping for 16 to 20 hours in a 24-hour period, though this varies. This is a normal physiologic finding, reflecting the rapid growth and high metabolic demands of infancy, and does not require immediate medical attention. The sleep is typically fragmented into short bouts.

Choice B rationale

Decreased urine output, specifically fewer than 6 to 8 wet diapers in 24 hours after the first few days of life, is a critical sign of dehydration and inadequate fluid intake, especially if the newborn is breastfed. This insufficient hydration can lead to hyperbilirubinemia, weight loss, and electrolyte imbalance, requiring prompt medical evaluation.

Choice C rationale

Newborn stools can normally be loose and frequent, especially in breastfed infants, who often pass stools several times a day. Stools in the first week progress from meconium to transitional to yellow, seedy, and loose, which is a normal finding and generally does not warrant contacting the provider unless signs of illness or diarrhea are present.

Choice D rationale

The umbilical cord stump usually dries and falls off within 1 to 3 weeks after birth due to a process of dry gangrene and separation. While most detach earlier, remaining attached after 1 week is still within the realm of normal variation and is not typically a cause for immediate concern unless signs of infection are present.
