Final answer:
The nurse should expect to administer Oxytocin to a client with heavy lochia and a boggy fundus following a vaginal delivery to stimulate uterine contractions and reduce the risk of postpartum hemorrhage.
Step-by-step explanation:
A nurse assessing a client following a vaginal delivery who notes heavy lochia and a boggy fundus should expect to administer oxytocin.
Oxytocin is a medication commonly used to promote uterine contractions to help the uterus return to its pre-pregnancy size, a process known as involution, and to reduce postpartum hemorrhage.
Given that Janine is experiencing minimal cervical dilation and the amniotic sac is intact at 41 weeks, pitocin, which is a synthetic form of oxytocin, is administered to augment labor and stimulate uterine contractions.
