Final answer:
The priority nursing intervention with PROM is to monitor for infection by closely observing for signs of infection and performing regular assessments of vital signs, temperature, and uterine contractions.
Step-by-step explanation:
A priority nursing intervention with PROM (premature rupture of membranes) is to monitor for infection. When the amniotic sac ruptures before 37 weeks of gestation, it increases the risk of infection for both the mother and the baby. The nurse should closely observe for signs of infection such as fever, abdominal pain, foul-smelling vaginal discharge, and increased heart rate. Additionally, the nurse should perform regular assessments of vital signs, temperature, and uterine contractions, and promptly report any abnormalities to the healthcare provider.
