For which patient would an L/S ratio of 2:1 potentially be considered abnormal?
- A. A 38-year-old gravida 2, para 1, who is 38 weeks’ gestation
- B. A 24-year-old gravida 1, para 0, who has diabetes
- C. A 44-year-old gravida 6, para 5, who is at term
- D. An 18-year-old gravida 1, para 0, who is in early labor at term
Correct Answer: B
Rationale: In diabetic pregnancies, an L/S ratio of 2:1 may not reliably indicate lung maturity due to delayed surfactant production.

During an ultrasound, two amnions and two placentas are observed. What will be the most likely result of this pregnancy?
- A. Dizygotic twins
- B. Monozygotic twins
- C. Conjoined twins
- D. High birth-weight twins
Correct Answer: A
Rationale: Dizygotic twins always have two amnions and two chorions (placentas).
A nurse is assessing a laboring person who is receiving oxytocin for labor induction. What is the most important intervention to prevent uterine hyperstimulation?
- A. monitor fetal heart rate
- B. increase fetal monitoring
- C. administer an epidural
- D. monitor contractions
Correct Answer: B
Rationale: The correct answer is B: increase fetal monitoring. Monitoring the fetus closely is crucial to detect signs of uterine hyperstimulation, such as non-reassuring fetal heart rate patterns. This allows for timely interventions to prevent fetal distress or hypoxia. Monitoring contractions (choice D) is important but does not directly address fetal well-being. Administering an epidural (choice C) may help manage pain but does not prevent uterine hyperstimulation. While monitoring fetal heart rate (choice A) is important, increasing the frequency of monitoring (choice B) is more specific to detecting complications related to oxytocin-induced uterine hyperstimulation.
The clinic nurse is obtaining a health history on a newly pregnant patient. Which is an indication for fetal diagnostic procedures if present in the health history?
- A. Maternal diabetes
- B. Weight gain of 25 lb
- C. Maternal age older than 30 years
- D. Previous infant weighing more than 3000 g at birth
Correct Answer: A
Rationale: Maternal diabetes is a risk factor in pregnancy due to possible impairment of placental perfusion, necessitating fetal diagnostic procedures.
During an ultrasound, two amnions and two placentas are observed. What will be the most likely result of this pregnancy?
- A. Dizygotic twins
- B. Monozygotic twins
- C. Conjoined twins
- D. High birth-weight twins
Correct Answer: A
Rationale: Dizygotic twins always have two amnions and two chorions (placentas).
The nurse is assessing the laboratory report of a 40-week gestation client. Which of the following values would the nurse expect to find elevated above prepregnancy levels? Select all that apply.
- A. Glucose.
- B. Fibrinogen.
- C. Hematocrit.
- D. Bilirubin.
Correct Answer: B
Rationale: Fibrinogen levels increase to prevent excessive blood loss during delivery, and white blood cell count rises to protect against infection. Glucose, hematocrit, and bilirubin levels should remain within normal limits.
