A nurse is caring for a newborn who is 70 hours old in the newborn nursery.

Exhibits

For each assessment finding, click to specify if the finding is consistent with hypoglycemia or neonatal abstinence syndrome (NAS). Each finding may support more than one disease process.

The condition that poses the greatest risk to the newborn is meconium aspiration syndrome due to amniotic fluid.

Rationale for correct answers

Meconium aspiration syndrome (MAS) occurs when a newborn inhales meconium-stained amniotic fluid, leading to airway obstruction, chemical pneumonitis, and surfactant dysfunction. The presence of dark brown-greenish amniotic fluid, along with mild respiratory distress (nasal flaring, increased respiratory rate of 60/min), raises concern for MAS. Close monitoring for worsening respiratory symptoms is essential.

Amniotic fluid contamination with meconium increases the risk of lung inflammation and infection. The newborn’s vigorous condition suggests mild aspiration, but continuous observation is needed.

Rationale for incorrect Response 1 options

• Jaundice: While term newborns may develop physiological jaundice, there are no indications of hyperbilirubinemia or hemolysis in this case.
• Hypoglycemia: No jitteriness or poor feeding, and birth weight is within normal range; hypoglycemia more commonly affects preterm or low birth weight infants.
• Cold stress: The newborn is under a radiant warmer, and temperature is within normal range (36.5°C).

Rationale for incorrect Response 2 options

• Birth weight: No signs of growth restriction or macrosomia-associated complications.
• Acrocyanosis: Normal in newborns due to immature circulation, not an indicator of respiratory compromise.
• Apgar scores: Strong Apgar scores (8 and 9) suggest good adaptation to extrauterine life.

Choice A rationale

Applying constant firm pressure to the penis for five minutes if bleeding occurs is an appropriate initial intervention for bleeding after a circumcision. However, it does not address the routine care needed after each diaper change to promote healing and prevent infection.

Choice B rationale

Cleansing the penis gently with water after each diaper change removes urine and stool, preventing irritation and potential infection. Applying a thin layer of petroleum jelly around the glans helps to keep the diaper from sticking to the healing circumcision site, reducing discomfort and promoting healing.

Choice C rationale

Prepackaged diaper wipes often contain fragrances and alcohol, which can irritate the sensitive skin of a newly circumcised penis and potentially delay healing or cause discomfort. Gentle cleansing with water is preferred.

Choice D rationale

The yellow exudate that forms on the glans after circumcision is a normal part of the healing process, known as granulation tissue. It should not be washed off, as this can disrupt healing and increase the risk of infection. It will typically disappear on its own over a few days.
