Extract:
Question 1 of 5
What is the function of the umbilical cord during pregnancy?
Correct Answer: A
Rationale: The correct answer is A. The umbilical cord functions to transport oxygen and nutrients from the mother to the fetus. This is crucial for the fetus's growth and development. B is incorrect because waste products are removed through the placenta, not the umbilical cord. C is incorrect as the umbilical cord does not regulate fetal temperature.
Choice D is incorrect as it includes all options, but only A is accurate.
Question 2 of 5
Which of the following is a potential complication of maternal obesity during pregnancy?
Correct Answer: D
Rationale: The correct answer is D, "All of the above." Maternal obesity during pregnancy can lead to gestational diabetes due to insulin resistance, preterm labor due to increased risk of premature birth, and placental abruption due to higher rates of hypertension and vascular complications. Choosing A, B, or C individually would be incorrect as they are all potential complications associated with maternal obesity.
Question 3 of 5
What is the recommended method of screening for Group B Streptococcus (GBS) during pregnancy?
Correct Answer: B
Rationale: The recommended method for screening GBS during pregnancy is a rectovaginal culture. This method involves swabbing the rectum and vagina to detect GBS colonization. This is crucial because GBS can be transmitted to the newborn during delivery, leading to serious infections. Urine culture (choice
A) is not recommended for GBS screening as it does not accurately reflect vaginal colonization. Blood test (choice
C) and nasopharyngeal culture (choice
D) are also not appropriate for GBS screening during pregnancy. Rectovaginal culture is the gold standard method for identifying GBS colonization in pregnant women.
Question 4 of 5
Which of the following is a potential complication of oligohydramnios?
Correct Answer: B
Rationale: The correct answer is B: Fetal growth restriction. Oligohydramnios is a condition characterized by low amniotic fluid levels, which can lead to poor fetal growth due to decreased cushioning and space for the fetus to move and grow. This can result in intrauterine growth restriction and potential complications for the baby. Preterm labor (choice
A) can also be associated with oligohydramnios due to issues with placental function, but it is not a direct complication of low amniotic fluid levels. Polyhydramnios (choice
C) is the opposite condition of oligohydramnios and is not a potential complication of it.
Therefore, the correct answer is B as it directly relates to the impact of oligohydramnios on fetal growth.
Question 5 of 5
Which stage of labor is characterized by the period between the end of the third stage and the mother's recovery from delivery?
Correct Answer: D
Rationale: The correct answer is D: Fourth stage. The fourth stage of labor is the period immediately following the delivery of the baby and placenta, lasting up to 2 hours. This stage is crucial for monitoring the mother's vital signs and ensuring she recovers from the delivery process. It is characterized by postpartum uterine contractions, monitoring for excessive bleeding, and observing for signs of maternal complications. The first stage refers to the onset of labor until full dilation, the second stage is active labor and delivery of the baby, and the third stage is the delivery of the placenta.
Therefore, the fourth stage is specifically focused on the mother's recovery from delivery, making it the correct choice.
