A nurse is caring for a client who is currently 34-weeks gestation. Which of the following medications would be avoided due to its category X classification?

A. Morphine is a category C medication, which means it may be used if the benefits outweigh the risks; it is not contraindicated in pregnancy. B. Famotidine (Pepcid) is also a category B medication and is generally considered safe to use during pregnancy. C. Misoprostol (Cytotec) is classified as category X due to its association with causing uterine contractions and the potential for fetal harm; thus, it should be avoided during pregnancy. D. Ibuprofen (Advil) is a category C medication, and while it is not typically recommended in the third trimester, it is not classified as category X.
