Final answer:
The nurse should inform the client that the Category D medication is known to cause adverse effects to the fetus, but may be prescribed if the benefits outweigh the risks. The client should be encouraged to discuss medication alternatives with the healthcare provider.
Step-by-step explanation:
The nurse's response to a client who is trying to get pregnant and currently takes a Category D pregnancy risk medication for the control of seizures should be: A. This med is prescribed if necessary but it is known to cause adverse effects to the fetus. It is important to explain to the client that Category D medications have potential risks to the fetus, but sometimes the benefits might outweigh the risks, especially if the medication is essential for the mother's health. The nurse should also encourage the client to discuss potential alternatives or adjustments in medication with their healthcare provider to optimize both maternal and fetal wellbeing. Prenatal care is crucial, and careful management of medication is part of ensuring the health of both mother and fetus.
