The normal volume of amniotic fluid is approximately _______________ mL at 37 weeks’ gestation.
- A. 1000
- B. 0.1
- C. 100
- D. 10000

Rationale: The volume of amniotic fluid steadily increases throughout pregnancy, reaching approximately 1000 mL at 37 weeks. This fluid is crucial for maintaining a stable environment for fetal development.
A woman missed her menstrual period 1 week ago and has come to the doctor’s office for a pregnancy test. Which placental hormone is measured in pregnancy tests?
- A. Progesterone
- B. Estrogen
- C. Human chorionic gonadotropin

The nurse is caring for a pregnant patient who has a BMI of 30. Which of the following complications is the patient at increased risk for during pregnancy?
- A. Preeclampsia and gestational diabetes
- B. Hyperemesis gravidarum and miscarriage
- C. Iron-deficiency anemia and urinary tract infections
- D. Gestational hypertension and placenta previa
Correct Answer: A
Rationale: The correct answer is A: Preeclampsia and gestational diabetes. A pregnant patient with a BMI of 30 is considered obese, increasing the risk of developing preeclampsia and gestational diabetes. Obesity is a known risk factor for these complications due to the increased strain on the body's systems. Preeclampsia is characterized by high blood pressure and protein in the urine, which can lead to serious complications for both the mother and the baby. Gestational diabetes is a type of diabetes that develops during pregnancy and can lead to complications for both the mother and the baby if not managed properly. The other choices (B, C, D) are not directly associated with obesity or a BMI of 30 during pregnancy, making them incorrect.
A laboring person on oxytocin for induction of labor should have continuous monitoring of the fetal heart rate. How often should the nurse assess the fetal heart rate?
- A. every 30 minutes
- B. every 15 minutes
- C. every 5 minutes
- D. every 1 hour
Correct Answer: B
Rationale: The correct answer is B: every 15 minutes. Continuous monitoring of the fetal heart rate is crucial during labor induction with oxytocin to promptly detect any signs of fetal distress. Assessing the fetal heart rate every 15 minutes allows for frequent monitoring to ensure the baby's well-being and timely intervention if needed. Assessing every 30 minutes (choice A) may not provide adequate monitoring frequency, every 5 minutes (choice C) is too frequent and may not be practical, and every 1 hour (choice D) is too long of an interval between assessments, potentially missing important changes in fetal status.
