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 with a BMI of 26.5 is seeking advice on weight gain during pregnancy at the first prenatal visit. Which of the following responses should the nurse provide?
- A. It would be best if you gained about 11 to 20 pounds.
- B. The recommendation for you is about 15 to 25 pounds.
- C. A gain of about 25 to 35 pounds is recommended for you.
- D. A gain of about 1 pound per week is the best pattern for you.
Correct Answer: B
Rationale: The correct answer is B (15 to 25 pounds) because this recommendation aligns with the guidelines for weight gain during pregnancy for a client with a BMI of 26.5. The Institute of Medicine recommends this weight gain range for individuals in the overweight category. It is important to strike a balance between gaining enough weight to support the health of the fetus and not gaining excess weight that may lead to complications.
Choice A (11 to 20 pounds) may not provide enough weight gain for optimal pregnancy outcomes, while choice C (25 to 35 pounds) may lead to excessive weight gain. Choice D (1 pound per week) is too specific and does not account for individual variations in weight gain patterns during pregnancy. It is crucial to tailor weight gain recommendations based on the client's BMI to ensure a healthy pregnancy.
A client at 36 weeks of gestation is suspected of having placenta previa. Which of the following findings support this diagnosis?
- A. Painless red vaginal bleeding
- B. Increasing abdominal pain with a non-relaxed uterus
- C. Abdominal pain with scant red vaginal bleeding
- D. Intermittent abdominal pain following the passage of bloody mucus
Correct Answer: A
Rationale: The correct answer is A: Painless red vaginal bleeding. This finding supports the diagnosis of placenta previa due to the characteristic symptom of painless bleeding in the third trimester. Placenta previa occurs when the placenta partially or completely covers the cervix, leading to bleeding as the cervix begins to dilate. The other choices are incorrect because increasing abdominal pain with a non-relaxed uterus (B) may indicate placental abruption, abdominal pain with scant red vaginal bleeding (C) is not typical of placenta previa, and intermittent abdominal pain following the passage of bloody mucus (D) is more suggestive of preterm labor or bloody show.
A nurse in a prenatal clinic overhears a newly licensed nurse discussing conception with a client. Which of the following statements by the newly licensed nurse requires intervention by the nurse?
- A. Fertilization takes place in the outer third of the fallopian tube.
- B. Implantation occurs between 6 to 10 days after conception.
- C. Sperm remain viable in the woman's reproductive tract for 2 to 3 days.
- D. Bleeding or spotting can accompany implantation.
Correct Answer: B
Rationale: The correct answer is B because implantation actually occurs around 6-10 days after fertilization, not after conception. This is a critical distinction as conception refers to the union of sperm and egg to form a zygote, while fertilization specifically refers to the fusion of the genetic material. Therefore, the statement by the newly licensed nurse is inaccurate and requires intervention.
A: Fertilization typically occurs in the outer third of the fallopian tube, making this statement correct.
C: Sperm can indeed remain viable in the woman's reproductive tract for 2 to 3 days, indicating this statement is accurate.
D: Bleeding or spotting can indeed accompany implantation, making this statement correct.
In summary, choice B is incorrect because implantation occurs around 6-10 days after fertilization, not conception. Choices A, C, and D are all correct statements related to conception and fertilization.
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.
When advising a woman considering pregnancy on nutritional needs to reduce the risk of giving birth to a newborn with a neural tube defect, what information should the nurse include?
- A. Limit alcohol consumption.
- B. Increase intake of iron-rich foods.
- C. Consume foods fortified with folic acid.
- D. Avoid foods containing aspartame.
Correct Answer: C
Rationale: The correct answer is C: Consume foods fortified with folic acid. Folic acid plays a crucial role in preventing neural tube defects in newborns. It is recommended that women of childbearing age consume 400 mcg of folic acid daily to reduce the risk. Foods fortified with folic acid include cereals, bread, and pasta.
A: Limit alcohol consumption - While important for overall health, alcohol consumption is not directly related to preventing neural tube defects.
B: Increase intake of iron-rich foods - Iron is essential during pregnancy, but it is not specifically linked to reducing the risk of neural tube defects.
D: Avoid foods containing aspartame - Aspartame is a sweetener and does not have a direct impact on neural tube defects prevention.
