What medication is used for cervical ripening?

Correct Answer: C

Rationale: The correct answer is C: misoprostol. Misoprostol is used for cervical ripening in obstetrics due to its ability to soften and dilate the cervix, making it favorable for induction of labor. It is a prostaglandin E1 analogue that helps prepare the cervix for childbirth. Amniotomy (A) is the artificial rupture of membranes and does not directly aid in cervical ripening. Hemabate (B) is a medication used to treat postpartum hemorrhage, not for cervical ripening. Progesterone (D) is a hormone that helps maintain pregnancy and is not used for cervical ripening.

Correct Answer: C

Rationale: The correct answer is C: postterm birth. Multiple gestation, such as twins or triplets, often leads to a higher risk of postterm birth due to the increased likelihood of preterm labor and delivery. This is because the uterus may become overdistended and unable to maintain the pregnancy to full term, resulting in postterm birth. Incorrect choices: A: Tachysystole is excessive uterine contractions, which is not directly related to multiple gestation. B: Postterm birth is already covered as the correct answer. D: Early decelerations are a common finding in labor but not specifically associated with multiple gestation complications.

Correct Answer: A

Rationale: The correct answer is A: cephalohematoma. When using a vacuum extractor during childbirth, the device applies suction to the baby's head to assist with delivery. This suction can cause a collection of blood between the baby's skull and periosteum, resulting in a cephalohematoma. This complication is due to the pressure exerted on the baby's head during the extraction process. Cephalohematoma is a common side effect of vacuum extraction and typically resolves on its own. Face presentation and fetal growth restriction are not directly related to the use of a vacuum extractor. Scalp fracture is a rare but serious complication that can occur if excessive force is applied during vacuum extraction, leading to bone injury, which is different from the collection of blood in a cephalohematoma.

Correct Answer: C

Rationale: The correct answer is C: velamentous insertion. In this condition, the umbilical cord vessels branch before reaching the placenta, making them vulnerable to compression and rupture. Placenta previa (A) refers to the placenta covering the cervix, not cord insertion. Placenta cervix (B) is not a recognized term. Vasa previa (D) is when fetal vessels traverse the fetal membranes overlying the cervix, not related to branching of umbilical cord vessels before insertion into the placenta.

Correct Answer: C

Rationale: The correct nursing intervention for prolapsed cord is to lift the presenting part off the cord to relieve pressure and improve blood flow to the fetus. This step prevents further compression of the blood vessels in the cord. Turning the person to the side (A) is not specific to addressing a prolapsed cord. Giving oxygen (B) may be necessary, but it does not directly address the issue of cord prolapse. Increasing oxytocin (D) can worsen the situation by causing stronger contractions, potentially further compressing the cord. Therefore, the most appropriate action is to lift the presenting part off the cord (C) to protect the blood flow to the fetus.
