A nurse is calculating the estimated date of birth using Nagele’s rule for a client who is pregnant and whose last menstrual cycle started June 21. What is the estimated date of delivery in the next year?

Choice A rationale

A Coombs positive result does not necessarily mean that the newborn will require immediate intervention. It indicates that the newborn should be monitored for potential complications such as jaundice and anemia.
Choice B rationale
While the newborn’s glucose level is within the normal range, this does not directly relate to the Coombs positive result.
Choice C rationale
A Coombs positive result may indicate Rh or ABO incompatibility, but this does not directly answer the question of what the nurse should anticipate.
Choice D rationale
This is the correct answer. A Coombs positive result indicates that the newborn should be monitored for signs of jaundice, as this could be a potential complication.

Choice A rationale
Maternal cytomegalovirus (CMV) infection is a serious health concern as it is associated with severe birth defects like sensori-neural hearing loss, impairment of cognitive development, and cerebral palsy. It is acquired by contact with body fluids and by vertical transmission from mother to fetus. Transmission can occur via the saliva and urine of the newborn, which is why this is the correct answer.
Choice B rationale
CMV does not require airborne precautions. It is not an airborne disease; it is spread through close, direct contact with a person infected with the virus.
Choice C rationale
CMV does not cause visible lesions on the mother’s genitalia. This is a characteristic of other sexually transmitted infections, not CMV2.
Choice D rationale
Mothers do not receive prophylactic treatment with acyclovir prior to delivery to prevent CMV2. Acyclovir is an antiviral medication used to treat herpes simplex virus infections, not CMV2.
