What is a common cause of oligohydramnios during pregnancy?

Correct Answer: C

Rationale: The correct answer is C: Premature rupture of membranes. Oligohydramnios is a condition characterized by low levels of amniotic fluid which can be caused by the premature rupture of membranes, leading to the leakage of amniotic fluid. This condition can result in various complications such as fetal growth restriction and compression of the umbilical cord. Maternal hypertension (choice A) is not a direct cause of oligohydramnios. Multiple gestations (choice B) may lead to polyhydramnios (excessive amniotic fluid) rather than oligohydramnios. Fetal macrosomia (choice D) is associated with increased amniotic fluid levels rather than decreased levels seen in oligohydramnios.

Correct Answer: C

Rationale: The correct answer is C: Importance of early ambulation. After a cesarean section, early ambulation is crucial to prevent complications like blood clots and promote circulation. It helps prevent post-operative complications. Choice A is important for respiratory health but not the priority right after surgery. Choice B focuses on perineal care which is important but not the immediate priority. Choice D is important, but recognizing signs of infection can wait until the client is more stable. Early ambulation is key to preventing complications and aiding in recovery.

Correct Answer: D

Rationale: The correct answer is D because the placenta performs multiple crucial roles in pregnancy. Firstly, it produces hormones essential for maintaining the pregnancy. Secondly, it provides nutrients and oxygen to the fetus for growth and development. Lastly, it removes waste products from the fetus to ensure a healthy environment. Choices A, B, and C individually do not cover all the functions of the placenta, making them incorrect. Selecting option D acknowledges the comprehensive functions of the placenta during pregnancy.

Correct Answer: D

Rationale: The correct answer is D because deep transverse arrest occurs when the level of the occiput and the sinciput is the same, leading to a failure of descent of the fetal head through the pelvis. This alignment issue hinders the progress of labor despite adequate contractions. A: Incorrect. Flexion being well maintained is not a defining characteristic of deep transverse arrest. B: Incorrect. While strong uterine contractions can contribute to labor challenges, deep transverse arrest is specifically related to the alignment of the fetal head. C: Incorrect. The curvature of the sacrum is not directly related to deep transverse arrest.

Correct Answer: C

Rationale: The correct answer is C because establishing an intravenous line is essential for immediate access to administer fluids, medications, and blood products during the emergency cesarean section. This step ensures that the patient's vital signs can be supported, and any emergent interventions can be readily delivered. A: While informed consent is important, in an emergency situation, the priority is to ensure the patient's immediate medical needs are met. B: Inserting a Foley's catheter may be necessary during the procedure, but it is not the most critical assessment prior to the cesarean section. D: Shaving the perineal area is not a priority in an emergency situation and may be done during the preparation for surgery.

Correct Answer: C

Rationale: The correct answer is C: Hyperemesis gravidarum. This condition is characterized by severe nausea, vomiting, weight loss, dehydration in pregnancy. It is more severe than typical morning sickness (choice A) and is not specific to multiple gestation (choice B). Hypertensive disorders (choice D) typically present with high blood pressure, proteinuria, and edema, not just nausea and vomiting. Hyperemesis gravidarum requires medical intervention due to potential complications from dehydration and malnutrition.

Correct Answer: A

Rationale: In face presentation, the face is an ill-fitting presenting part, leading to obstructed labor. The face has larger diameters, making it difficult to pass through the birth canal. This differs from vertex delivery where the head can mold to fit. Caput succedaneum is swelling of the soft tissues on the baby's head and does not directly cause obstructed labor.

Correct Answer: B

Rationale: The correct answer is B: Turtle sign. This occurs when the fetal head retracts against the perineum during delivery, resembling a turtle retracting into its shell. This indicates fetal shoulder dystocia, a serious complication. Gaskin sign (A) refers to the position of the mother during labor. Klumpke sign (C) is related to brachial plexus injuries during delivery. Chignon sign (D) is not a recognized term in obstetrics.

Correct Answer: C

Rationale: The correct answer is C: Premature rupture of membranes.

This condition can result in various complications such as fetal growth restriction and compression of the umbilical cord. Maternal hypertension (choice A) is not a direct cause of oligohydramnios.
