A 32-week pregnant woman is admitted with preterm labor. What is the most appropriate intervention to delay labor?
- A. Administer magnesium sulfate
- B. Perform an emergency cesarean section
- C. Administer a prostaglandin inhibitor
- D. Start a Pitocin infusion
Correct Answer: A
Rationale: The correct answer is A: Administer magnesium sulfate. Magnesium sulfate is commonly used to delay preterm labor by relaxing uterine smooth muscle. It inhibits contractions and delays labor progression. It is a standard treatment to prevent preterm birth and reduce the risk of complications for both the mother and the baby.
Choice B: Emergency cesarean section is not indicated for delaying preterm labor unless there are severe complications putting the mother or baby at immediate risk.
Choice C: Administering a prostaglandin inhibitor may help in some cases, but magnesium sulfate is the preferred choice for delaying labor in preterm pregnancies.
Choice D: Starting a Pitocin infusion would actually stimulate contractions and hasten labor, which is the opposite of what is needed in this scenario.
A nurse is caring for a laboring person who is receiving an epidural. What is the most important nursing intervention when administering an epidural?
- A. Ensure the person is positioned correctly
- B. Monitor the person's blood pressure
- C. Monitor the person's oxygen saturation
- D. Administer a pain medication
Correct Answer: A
Rationale: The correct answer is A: Ensure the person is positioned correctly. This is crucial because proper positioning ensures the medication is distributed correctly and helps prevent complications like uneven distribution or nerve injury. Monitoring blood pressure (B) and oxygen saturation (C) are important but secondary to ensuring correct positioning. Administering pain medication (D) is not a nursing intervention specific to epidural administration.

- A. Relieve back strain.
- B. Improve development of colostrum.
- C. Ripen the cervix.
- D. Reduce the incidence of hemorrhoids.
Correct Answer: C
Rationale: Evening primrose oil is believed to help ripen the cervix in preparation for labor. It is not typically used to relieve back strain, improve colostrum development, or reduce hemorrhoids.
A nurse is caring for a pregnant patient who is experiencing nausea and vomiting. Which of the following should be included in the teaching plan?
- A. Eat small, frequent meals and avoid spicy or fatty foods.
- B. Drink large amounts of water to flush out toxins.
- C. Lie flat on your back to help settle your stomach.
- D. Avoid eating any food until the nausea resolves completely.
Correct Answer: A
Rationale: The correct answer is A: Eat small, frequent meals and avoid spicy or fatty foods. This is because small, frequent meals can help manage nausea by preventing the stomach from becoming too full, while avoiding spicy or fatty foods can reduce irritation and ease digestion. Option B is incorrect as excessive water intake can worsen nausea. Option C is wrong as lying flat on the back can exacerbate nausea and is not recommended during pregnancy. Option D is incorrect because skipping meals can lead to low blood sugar levels, worsening nausea. Overall, choice A aligns with evidence-based strategies for managing nausea and vomiting in pregnancy.
