What is a possible complication of oligohydramnios?

Correct Answer: D

Rationale: The correct answer is D: fetal growth restriction. Oligohydramnios refers to low levels of amniotic fluid, which can restrict fetal growth due to decreased cushioning and space for movement. This can lead to complications such as poor fetal nutrition, musculoskeletal abnormalities, and pulmonary hypoplasia. Fetal macrosomia (A) is the opposite of fetal growth restriction, preterm labor (B) is not directly associated with oligohydramnios, and placenta previa (C) is a separate condition involving the placenta's position in the uterus.

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.

Correct Answer: C

Rationale: The correct answer is C: administration of magnesium sulfate. This is because magnesium sulfate is used to control bleeding in cases of retained products of conception in a spontaneous abortion. It works by causing uterine contractions, which help expel the remaining tissue and stop the bleeding. Surgery for dilation and curettage (choice A) is typically performed if bleeding persists after medical management. Surgery for a hysterectomy (choice B) is not necessary for managing bleeding in this situation. Administration of calcium gluconate (choice D) is not indicated for controlling bleeding in cases of retained products of conception.
