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?
March 14
March 21
March 28
April 4
The Correct Answer is C
Step 1: According to Naegele’s rule, we start with the first day of the last menstrual period, which is June 212.
Step 2: We then subtract three months, which gives us March 212.
Step 3: Finally, we add seven days, which gives us March 282. So, the estimated date of delivery in the next year is March 28.

Correct Answer is D
Explanation
Choice A rationale
Decreasing the rate of IV fluids would not address the issue of late decelerations, which are a sign of fetal hypoxia.
Choice B rationale
Elevating the client’s head would not address the issue of late decelerations.
Choice C rationale
Performing fetal scalp stimulation is used to assess fetal well-being when the tracing is nonreactive, not when late decelerations are present.
Choice D rationale
Administering oxygen via a face mask is the correct answer. This increases maternal oxygen saturation, which can help increase oxygen delivery to the fetus.
Correct Answer is A
Explanation
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.
