1. A nurse is caring for several clients. The nurse should recognize that it is safe to administer tocolytic therapy to which of the following clients?
- A. A client who is experiencing fetal death at 32 weeks of gestation
- B. A client who is experiencing preterm labor at 26 weeks of gestation
- C. A client who is experiencing Braxton-Hicks contractions at 36 weeks of gestation
- D. A client who has a post-term pregnancy at 42 weeks of gestation
Correct answer: B
Rationale: Tocolytic therapy is used to suppress premature labor. It is appropriate to administer it to a client experiencing preterm labor at 26 weeks of gestation to help delay delivery and improve neonatal outcomes. Administering tocolytic therapy to a client experiencing fetal death, Braxton-Hicks contractions, or post-term pregnancy is not indicated and may not be safe or effective in these situations. Fetal death at 32 weeks indicates a non-viable pregnancy, Braxton-Hicks contractions are normal and not indicative of preterm labor, and post-term pregnancy at 42 weeks does not require tocolytic therapy.
2. A newborn is noted to have secretions bubbling out of the nose and mouth after delivery. What is the nurse's priority action?
- A. Suction the nose with a bulb syringe.
- B. Suction the mouth with a bulb syringe.
- C. Use a suction catheter with low negative pressure.
- D. Turn the newborn on their side.
Correct answer: B
Rationale: The priority action for the nurse is to suction the mouth with a bulb syringe. Suctioning the mouth first is crucial to prevent aspiration and ensure the airway is clear, which takes precedence over suctioning the nose. This intervention helps maintain a patent airway and promotes adequate breathing in the newborn. Using a suction catheter with low negative pressure may not be appropriate as the newborn needs a gentle suction method like a bulb syringe. Turning the newborn on their side is important if there is a risk of aspiration, but clearing the mouth of secretions should be the priority to establish a clear airway.
3. A client is scheduled for a maternal serum alpha-fetoprotein test at 15 weeks of gestation. The client asks the nurse about the purpose of this test. What explanation should the nurse provide?
- A. This test screens for neural tube defects and other developmental abnormalities in the fetus.
- B. It assesses various markers of fetal well-being.
- C. This test identifies an Rh incompatibility between the mother and fetus.
- D. It is a screening test for spinal defects in the fetus.
Correct answer: A
Rationale: The maternal serum alpha-fetoprotein (MSAFP) test is performed around 15-18 weeks of gestation to screen for neural tube defects and other developmental abnormalities in the fetus, not to assess fetal lung maturity, markers of fetal well-being, or Rh incompatibility between the mother and fetus. Choice A is the correct answer as it accurately reflects the purpose of the MSAFP test. Choices B, C, and D are incorrect because they do not align with the primary goal of this screening test.
4. When calculating the Apgar score of a newborn at 1 minute after delivery, which of the following findings would result in a score of 6?
- A. 4
- B. 5
- C. 6
- D. 7
Correct answer: C
Rationale: The Apgar score is calculated based on five parameters: heart rate, respiratory effort, muscle tone, reflex irritability, and color. In this case, the newborn's findings at 1 minute after delivery indicate a heart rate >100/min (2 points), slow, weak cry (1 point), some flexion of extremities (1 point), grimace in response to suctioning (1 point), and body pink with blue extremities (1 point). Adding these points together results in a total Apgar score of 6, reflecting the newborn's initial assessment for their overall well-being. Choice A (4) is too low based on the given findings, while Choice B (5) is also lower than the correct score of 6. Choice D (7) is too high as it would require additional findings to reach that score.
5. A client is scheduled for a cesarean birth based on fetal lung maturity. Which finding indicates that the fetal lungs are mature?
- A. Absence of Phosphatidylglycerol (PG)
- B. Biophysical profile score of 8
- C. Lecithin/sphingomyelin (L/S) ratio of 2:1
- D. Reactive nonstress test
Correct answer: C
Rationale: An L/S ratio of 2:1 indicates fetal lung maturity, as it signifies the presence of surfactant in the amniotic fluid, which helps with lung expansion and prevents collapse at the end of expiration. The absence of PG indicates immaturity of the fetal lungs, as PG appears in the amniotic fluid during the later stages of lung maturation. Biophysical profile scores and nonstress tests are assessments of fetal well-being and do not directly indicate fetal lung maturity. Therefore, choice C is the correct answer.
