A nurse is caring for a client in the emergency department who is in active labor on December 26. The client reports their last menstrual period was around April 1. Which of the following ages is the anticipated gestational age of the fetus?

Choice A rationale

Herpes simplex virus 2 (HSV-2) can be harmful to a developing fetus and newborn. While primary infection during the first trimester can rarely lead to congenital anomalies, the most significant risk is neonatal herpes, which occurs when the newborn is exposed to the virus during passage through the birth canal if active lesions are present. Neonatal herpes can cause severe, life-threatening complications.

Choice B rationale

Transmission of HSV-2 to the newborn is significantly higher if active genital lesions are present at the time of vaginal birth. The virus can be shed from these lesions and infect the infant as they pass through the birth canal. Therefore, a Cesarean section is typically recommended if active lesions are present at the onset of labor.

Choice C rationale

Wearing tight-fitting undergarments can increase moisture and friction, potentially irritating existing lesions and hindering healing. Loose-fitting cotton undergarments are generally recommended to allow air circulation and reduce irritation, promoting a more favorable environment for lesion resolution and comfort.

Choice D rationale

Antiviral medications, such as acyclovir, valacyclovir, or famciclovir, can help manage genital herpes by reducing the frequency, duration, and severity of outbreaks. They work by inhibiting viral replication. However, these medications do not cure the condition; HSV-2 remains a lifelong viral infection.

Choice A rationale

Immediately bathing a newborn with herpes simplex virus is generally discouraged. While it might seem intuitive for infection control, vigorous bathing could theoretically disrupt skin integrity and potentially spread the virus to other areas of the body or mucous membranes, exacerbating the infection.

Choice B rationale

Initiating contact precautions is essential for a newborn with herpes simplex virus. This highly contagious viral infection requires strict measures to prevent transmission to other vulnerable neonates and healthcare providers. Contact precautions involve gown and glove use, limiting direct contact with the newborn or contaminated surfaces.

Choice C rationale

Administering ampicillin IV is not the appropriate treatment for herpes simplex virus. Ampicillin is an antibiotic effective against bacterial infections, not viral infections like herpes simplex. Antiviral medications, such as acyclovir, are the specific treatment for neonatal herpes simplex virus to inhibit viral replication.

Choice D rationale

Withholding breastfeeding is not typically indicated for a newborn with in utero transmitted herpes simplex virus unless the mother has active lesions on her breasts. The primary concern is direct skin-to-skin transmission if lesions are present. Breast milk itself provides beneficial antibodies and is not a route of transmission for in utero infection.
