A nurse should screen clients of childbearing age for pregnancy as the administration of which of the following vaccines is contraindicated during pregnancy?
Influenza.
Tetanus.
Rhogam.
MMR.
The Correct Answer is C
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.

Correct Answer is B
Explanation
Choice A rationale:
Alkylating agents. Alkylating agents are not cell cycle-specific. These agents work by directly binding to DNA and interfering with the cell's ability to replicate and divide. Their action is not limited to a specific phase of the cell cycle, making them non-cell cycle-specific agents. Alkylating agents are often used in cancer chemotherapy to prevent cell division and growth.
Choice C rationale:
Antineoplastic antibiotics. Antineoplastic antibiotics are not cell cycle-specific either. These drugs, such as doxorubicin and bleomycin, work by disrupting DNA and RNA synthesis and are used to treat various types of cancer. However, they do not specifically target cells in a particular phase of the cell cycle.
Choice D rationale:
Retinoids. Retinoids are not cell cycle-specific antineoplastic agents. Retinoids are compounds related to vitamin A and are used for various medical purposes, including some cancer treatments. However, their mechanism of action is not tied to a specific phase of the cell cycle, making them non-cell cycle-specific.
Choice B rationale:
Plant alkaloids. Plant alkaloids, such as vinca alkaloids (vincristine and vinblastine) and taxanes (paclitaxel), are considered cell cycle-specific antineoplastic drugs. These agents interfere with microtubule function, which is critical during mitosis (cell division). By disrupting microtubules, they specifically target rapidly dividing cancer cells during the M phase of the cell cycle. This selectivity for actively dividing cells makes plant alkaloids cell cycle-specific antineoplastic drugs.
