Final answer:
The PCP should prescribe betamethasone to hasten fetal lung maturity in a client at 32 weeks gestation diagnosed with preterm labor.
Step-by-step explanation:
The medication that the PCP should prescribe to hasten fetal lung maturity in a client at 32 weeks gestation diagnosed with preterm labor is betamethasone.
Betamethasone is a corticosteroid medication that is given to pregnant women at risk of preterm delivery to help mature the fetal lungs. It is given as an injection to the mother to help promote lung development in the baby.
By accelerating the production of surfactant, a substance that keeps the air sacs in the lungs open, betamethasone helps prevent respiratory distress syndrome (RDS) in premature infants.
