Which medication should be avoided in labor and delivery clients?

Phenytoin, an anticonvulsant medication, should be approached with caution during labor and delivery due to its potential effects on both the mother and the fetus. While it is important to manage seizure disorders effectively, the use of phenytoin can lead to complications such as fetal toxicity and alterations in the maternal blood pressure and heart rate. Additionally, it may have implications for neonatal outcomes, such as increased risk for vitamin K deficiency or bleeding disorders in newborns, which can be particularly critical in the perinatal period when both maternal and fetal health are closely monitored.

Other medications listed have different contexts pertaining to labor and delivery. For instance, ibuprofen is typically avoided late in pregnancy due to concerns about early closure of the ductus arteriosus in the fetus, but its use during labor is less problematic compared to phenytoin. Lisinopril, an ACE inhibitor for hypertension, poses risks if taken during pregnancy, especially in the second and third trimesters, due to potential fetal renal harm but is not directly related to immediate labor and delivery. Vitamin K is crucial for newborns but is not a concern during labor and delivery itself.

In summary, the selection of phenytoin highlights the need to carefully consider
