Which instruction should a nurse include in the discharge plan for a client treated for preterm labor?

Avoiding sexual intercourse is a crucial instruction for clients who have been treated for preterm labor. This recommendation is grounded in the understanding that sexual activity can stimulate uterine contractions, which may provoke or worsen preterm labor. In the context of managing a pregnancy that has faced complications like preterm labor, it's essential for clients to minimize any activities that may place additional stress on the uterus.

In addition to this recommendation, the other options could be important in different contexts but are not as directly related to managing the specific risks associated with preterm labor. Regular physical activity, for instance, is generally encouraged during a healthy pregnancy but may need to be limited in circumstances involving preterm labor. Monitoring fetal movements is also a valuable practice, but in this situation, it does not specifically address risk mitigation related to preterm contractions. Rising fluid intake can be beneficial in terms of overall hydration and sometimes in avoiding uterine irritability, but it is not a priority compared to the directive to avoid sexual activity.
