Question 1 of 5
Which of the following tests is used to assess fetal lung maturity?
Correct Answer: D
Rationale: The correct answer is D: Lecithin-sphingomyelin (L/S) ratio. This test is used to assess fetal lung maturity by measuring the ratio of two substances found in the amniotic fluid. An L/S ratio greater than 2:1 is indicative of mature fetal lungs. This test is crucial in determining if a baby can breathe adequately after birth. The other choices are incorrect because:
A) Non-stress test monitors fetal heart rate and movements,
B) Biophysical profile assesses fetal well-being, and
C) Amniocentesis is a procedure to collect amniotic fluid for genetic testing.
Question 2 of 5
What is the recommended amount of weight gain during pregnancy for a woman with a normal BMI?
Correct Answer: B
Rationale: The correct answer is B (20-30 pounds). This range is recommended for pregnant women with a normal BMI to support the health of both the mother and the baby. Gaining too little weight can lead to complications like low birth weight, while gaining too much weight increases the risk of gestational diabetes and high blood pressure. The other choices are incorrect because they either fall below or exceed the recommended weight gain range, which can pose risks to the pregnancy. It is crucial for the mother to maintain a healthy weight gain to ensure a safe and successful pregnancy.
Question 3 of 5
Which of the following is a potential complication of gestational diabetes?
Correct Answer: C
Rationale: The correct answer is C: Polyhydramnios. Gestational diabetes can lead to increased fetal growth and higher amniotic fluid levels, causing polyhydramnios. This can lead to complications during delivery.
Incorrect choices:
A: Hyperglycemia is a symptom of gestational diabetes, not a complication.
B: Hypoglycemia is not a common complication of gestational diabetes.
D: Hypertension is not directly linked to gestational diabetes complications.
Question 4 of 5
Which stage of labor is characterized by cervical dilation from 4-10 cm?
Correct Answer: A
Rationale: The correct answer is A: First stage. This stage of labor is characterized by cervical dilation from 4-10 cm. During this stage, the cervix prepares for childbirth by thinning and opening up to allow the baby to pass through the birth canal. The first stage is further divided into early labor (0-4 cm dilation) and active labor (4-10 cm dilation). It is crucial for monitoring progress and determining when to move to the next stage of labor. The other choices are incorrect because the second stage is characterized by pushing and delivery of the baby, the third stage is delivery of the placenta, and the fourth stage is the postpartum period immediately after delivery.
Question 5 of 5
What is the most common type of anesthesia used during labor?
Correct Answer: A
Rationale: The correct answer is A: Epidural. Epidural anesthesia is the most common type used during labor because it provides pain relief while allowing the mother to remain awake and actively participate in the delivery. It works by blocking nerve signals in the lower spine, numbing the lower half of the body. This allows the mother to have a more comfortable labor experience without losing consciousness. Spinal anesthesia (
B) is similar but is typically used for cesarean sections. General anesthesia (
C) is rarely used during labor due to the potential risks to the baby. Local anesthesia (
D) is not commonly used for labor as it only numbs a small area and is not sufficient for the pain relief needed during childbirth.
