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: The correct answer is C: Lecithin/sphingomyelin (L/S) ratio of 2:1. This ratio indicates fetal lung maturity as it signifies adequate production of surfactant in the fetal lungs, essential for proper lung function after birth. Absence of Phosphatidylglycerol (PG) (Choice A) indicates immaturity, Biophysical profile score of 8 (Choice B) assesses overall fetal well-being, not lung maturity, and Reactive nonstress test (Choice D) evaluates fetal well-being, not lung maturity. The L/S ratio of 2:1 is the most reliable indicator of fetal lung maturity.

A client in active labor has 7 cm of cervical dilation, 100% effacement, and the fetus at 1+ station. The client's amniotic membranes are intact, but she suddenly expresses the need to push. What should the nurse do?
- A. Assist the client into a comfortable position.
- B. Observe the perineum for signs of crowning.
- C. Have the client pant during the next contractions.
- D. Help the client to the bathroom to void.
Correct Answer: C
Rationale: Rationale: Option C, having the client pant during the next contractions, is the correct answer. At 7 cm dilation with a sudden urge to push, it indicates possible fetal descent. Panting can help prevent rapid descent and reducing the risk of cervical edema or injury. It allows time for the cervix to dilate fully before pushing, preventing premature pushing and potential complications. Option A is not a priority at this stage. Option B is incorrect as observing for crowning might lead to premature pushing. Option D is not necessary as voiding is not the priority right now.
A healthcare professional is assessing a newborn immediately following a scheduled cesarean delivery. Which of the following assessments is the healthcare professional's priority?
- A. Respiratory distress
- B. Hypothermia
- C. Accidental lacerations
- D. Acrocyanosis
Correct Answer: A
Rationale: The correct answer is A: Respiratory distress. This is the priority assessment because a newborn's ability to breathe is crucial for survival. Immediate evaluation of respiratory status is essential to ensure the baby is receiving adequate oxygenation. Hypothermia (choice B) can be addressed after addressing any respiratory issues. Accidental lacerations (choice C) are important but not as immediately life-threatening as respiratory distress. Acrocyanosis (choice D) is a common finding in newborns and does not require immediate intervention unless associated with other concerning symptoms.
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 correct answer is A because the maternal serum alpha-fetoprotein test is specifically used to screen for neural tube defects and other developmental abnormalities in the fetus. Alpha-fetoprotein levels in the mother's blood can indicate the presence of such abnormalities. This test is typically done around 15-20 weeks of gestation.
Choice B is incorrect because the maternal serum alpha-fetoprotein test is not used to assess various markers of fetal well-being. Choice C is incorrect because it does not identify Rh incompatibility, which is typically detected through other tests. Choice D is incorrect because the test is not primarily for spinal defects, but rather for neural tube defects and other developmental abnormalities.
When monitoring uterine contractions in a client in the active phase of the first stage of labor, which finding should the nurse report to the provider?
- A. Contractions lasting longer than 90 seconds
- B. Contractions occurring every 3 to 5 minutes
- C. Contractions are strong in intensity
- D. Client reports feeling contractions in the lower back
Correct Answer: A
Rationale: Rationale: Contractions lasting longer than 90 seconds can indicate uterine hyperstimulation, which can lead to decreased oxygenation of the fetus. This finding should be reported to the provider for further assessment and intervention. Contractions occurring every 3 to 5 minutes (choice B) are normal in the active phase of labor. Strong contractions (choice C) are also expected during this phase. Feeling contractions in the lower back (choice D) is common and not typically a cause for concern. Reporting contractions lasting longer than 90 seconds is crucial to ensure the safety of both the mother and the baby.
A client in active labor is being prepared for epidural analgesia. Which of the following actions should the nurse take?
- A. Have the client sit upright on the bed with legs crossed.
- B. Administer a 500 mL bolus of lactated Ringer's solution prior to induction.
- C. Inform the client that the anesthetic effect will last for approximately 2 hours.
- D. Obtain a 30-minute electronic fetal monitoring (EFM) strip prior to induction.
Correct Answer: D
Rationale: The correct answer is D: Obtain a 30-minute electronic fetal monitoring (EFM) strip prior to induction. This is important to assess the fetal well-being and baseline status before initiating epidural analgesia. It helps in detecting any fetal distress or abnormalities that may be exacerbated by the epidural.
A: Having the client sit upright with legs crossed is not recommended as it may interfere with the procedure and comfort of the client.
B: Administering a 500 mL bolus of lactated Ringer's solution is not directly related to preparing for epidural analgesia.
C: Informing the client about the duration of anesthetic effect is important, but ensuring fetal well-being through EFM monitoring is a priority before the procedure.
