Final answer:
The primary health care provider may prescribe tocolytics to delay labor, corticosteroids for fetal lung development, and prepare for neonatal intensive care in case of the premature birth of the baby at 34 weeks of gestation.
Step-by-step explanation:
The nurse would expect the primary health care provider to prescribe interventions to address the preterm labor if a pregnant client has an onset of labor at 34 weeks of gestation.
Preterm labor is labor that occurs before the 37th week of pregnancy. The primary health care provider may prescribe medications to halt or delay labor to give the fetus more time to develop, as well as steroids to accelerate fetal lung maturity, reducing the risk of respiratory distress syndrome.
These medications could include tocolytics, which are drugs that inhibit labor, and corticosteroids to facilitate the maturation of the baby's lungs. In addition, if birth is imminent, care would include preparations for neonatal intensive care to provide support for the premature infant after delivery.
