The nurse is teaching a prenatal class about fetal circulation. What structure allows blood to bypass the fetal lungs?

Rationale: Misoprostol is a prostaglandin E1 analog that is commonly used for labor induction. It is particularly useful in clients with a previous uterine incision, such as a cesarean section scar, because it helps soften the cervix and promote uterine contractions, which can lead to successful vaginal birth after cesarean (VBAC). Misoprostol can be an effective method for inducing labor in these clients while minimizing the risk of uterine rupture. However, it is important to closely monitor clients for signs of uterine hyperstimulation when using misoprostol for labor induction.

Correct Answer: A

Rationale: In the case of placental accreta, where the placenta is abnormally attached to the uterine wall, it can be very difficult to detach the placenta without significant bleeding. In severe cases, the safest intervention to prevent life-threatening hemorrhage is a hysterectomy, which involves the removal of the uterus. This is a serious surgical procedure that may be necessary to save the mother's life. Other interventions mentioned in the options (IV antibiotic, IV Pitocin, 2L oxygen by mask) may be part of the management plan but would not address the underlying issue of placental accreta like a hysterectomy would.

Correct Answer: C

Correct Answer: B

Rationale: Female condoms provide dual protection against pregnancy and STIs.
