A nurse is assessing a 1-hour-old newborn.
Which of the following findings should the nurse report to the provider?

Choice A rationale

Droplet precautions are implemented for pathogens transmitted via large respiratory droplets, such as influenza or meningococcal disease. Herpes simplex virus is typically transmitted through direct contact with lesions or secretions, not primarily through airborne droplets. Therefore, instituting droplet precautions would not be the most scientifically appropriate measure for preventing HSV transmission in this context.

Choice B rationale

Ceftriaxone sodium is a broad-spectrum cephalosporin antibiotic used to treat bacterial infections, such as gonorrhea or bacterial meningitis. Herpes simplex virus is a viral infection, and antibiotics are ineffective against viruses. Administering ceftriaxone would not address the underlying viral etiology of the newborn's exposure to HSV.

Choice C rationale

Bottle-feeding the newborn is not a primary intervention to prevent transmission of HSV from a mother with active genital herpes to a newborn. HSV is transmitted through direct contact during passage through the birth canal. Breastfeeding is generally considered safe for mothers with HSV unless there are active lesions on the breast.

Choice D rationale

Obtaining surface cultures from the newborn is a crucial diagnostic step to confirm the presence of HSV infection in a neonate exposed during birth. This allows for timely initiation of antiviral therapy, such as acyclovir, which is essential to prevent systemic dissemination and severe complications like encephalitis, which can be life-threatening in newborns.

Choice A rationale: A shrill, high-pitched cry is more commonly associated with increased intracranial pressure or neonatal abstinence syndrome (withdrawal) rather than hypoglycemia. While a hypoglycemic infant may be irritable, their cry is typically described as weak or absent due to low energy reserves.

Choice B rationale: Weak peripheral pulses are a sign of poor perfusion or cardiovascular compromise, such as coarctation of the aorta or neonatal shock. Hypoglycemia primarily affects neurological and muscular function rather than directly causing a decrease in pulse strength.

Choice C rationale: Yellowish skin, or jaundice, is caused by elevated bilirubin levels (hyperbilirubinemia). While severe jaundice can lead to neurological issues, it is a separate metabolic concern from blood glucose instability.

Choice D rationale: Hypotonia, or "floppiness," is a classic clinical manifestation of neonatal hypoglycemia. When the brain and muscles are deprived of adequate glucose, the newborn lacks the energy to maintain normal muscle tone. Other key signs include jitteriness, lethargy, poor feeding, and a subnormal temperature.
