A nurse should screen clients of childbearing age for pregnancy as the administration of which of the following vaccines is contraindicated during pregnancy?

Choice A rationale:

Influenza vaccine is not contraindicated during pregnancy. In fact, the influenza vaccine is recommended for pregnant women because they are at higher risk of complications from influenza. It can protect both the pregnant woman and her baby from the flu.

Choice B rationale:

Tetanus vaccine is not contraindicated during pregnancy. In fact, tetanus vaccination during pregnancy is essential to protect both the mother and the newborn. Tetanus can be life-threatening, and vaccination is a preventive measure.

Choice C rationale:

Rhogam is contraindicated during pregnancy if the mother is Rh-negative and the baby is also Rh-negative. Rhogam is given to Rh-negative mothers to prevent sensitization to Rh-positive blood in case of fetal-maternal bleeding. If both the mother and baby are Rh-negative, there's no need for Rhogam during pregnancy.

Choice D rationale:

MMR (Measles, Mumps, Rubella) vaccine is contraindicated during pregnancy. It contains live attenuated viruses and is generally not recommended for pregnant women due to the theoretical risk of transmitting the virus to the developing fetus. It's typically given postpartum if the woman is not already immune to these diseases.
