A biophysical profile is performed on a pregnant patient. The results show a nonreactive stress test (NST), three episodes of fetal breathing movements (FBMs), limited gross movements, opening and closing of the hand indicating the presence of fetal tone, and adequate amniotic fluid index (AFI). What is the correct interpretation of this test result?
- A. A score of 10 would indicate that the results are equivocal.
- B. A score of 8 would indicate normal results.
- C. A score of 6 would indicate that birth should be considered as a possible treatment option.
- D. A score of 9 would indicate reassurance.
Correct Answer: B
Rationale: A biophysical profile score of 8-10 is considered normal, indicating fetal well-being.

A nurse is educating a pregnant patient on the importance of folic acid. Which of the following statements by the patient indicates that the teaching has been effective?
- A. I will take folic acid throughout my entire pregnancy to support fetal development.
- B. I will start taking folic acid after the first trimester to help prevent birth defects.
- C. I should only take folic acid if I have a family history of birth defects.
- D. Folic acid will help reduce the risk of gestational diabetes and hypertension.
Correct Answer: A
Rationale: The correct answer is A because taking folic acid throughout the entire pregnancy is crucial for supporting fetal development, especially in the early stages when the neural tube is forming. This statement reflects the patient's understanding of the importance of consistent folic acid intake during pregnancy.
Choice B is incorrect because waiting until after the first trimester misses the critical period when the neural tube develops. Choice C is incorrect as folic acid is recommended for all pregnant women regardless of family history. Choice D is incorrect because while folic acid is beneficial for fetal development, it is not specifically linked to reducing the risk of gestational diabetes or hypertension.
A nurse is preparing a laboring person for an epidural. What is the most important nursing action prior to the procedure?
- A. ensure the birthing person is in a sitting position
- B. check for allergies to anesthesia
- C. ensure informed consent is obtained
- D. administer IV fluids
Correct Answer: C
Rationale: The correct answer is C: ensure informed consent is obtained. Prior to any medical procedure, including epidural administration, it is crucial to obtain informed consent from the patient. This involves explaining the procedure, risks, benefits, and alternatives to the patient, ensuring they understand and voluntarily agree to the procedure. Without informed consent, the procedure cannot proceed ethically.
Choice A (ensure the birthing person is in a sitting position) is not the most important action as the position can be adjusted during the procedure. Choice B (check for allergies to anesthesia) is important but obtaining informed consent takes precedence. Choice D (administer IV fluids) is not a priority before obtaining informed consent.
