Final answer:
The pregnant woman can go home when her preterm labor is stabilized and home health visits are arranged.
Step-by-step explanation:
The most accurate response by the nurse would be: "When we can stabilize your preterm labor and arrange home health visits."
Preterm labor refers to labor that occurs after 20 weeks but before 37 weeks of gestation. Tocolytic medications are used to control and delay preterm labor to give the baby more time to mature in the womb. Once the woman's preterm labor is stabilized, the nurse can arrange for home health visits, where monitoring and care can continue.
