What is the LNG-IUC mechanism of action?
- A. disruption of fertilization of the egg and sperm
- B. termination of a pregnancy
- C. creation of a hostile uterine environment
- D. thickening cervical mucus, atrophic endometrium
Correct Answer: D
Rationale: The LNG-IUC, or levonorgestrel-releasing intrauterine system, works primarily by thickening the cervical mucus, which inhibits the passage of sperm through the cervix. This mechanism reduces the likelihood of fertilization occurring. Additionally, LNG-IUC also causes atrophic changes in the endometrium, which makes it less conducive for implantation of a fertilized egg, further decreasing the chance of pregnancy.

During preconception counseling the nurse explains the time-period as when the fetus is most vulnerable to the effects of teratogens occurs is which of the following?
- A. 2 to 8 weeks
- B. 4 to12 weeks
- C. 5 to 10 weeks
- D. 6 to 15 weeks
Correct Answer: A
Rationale: The time period when the fetus is most vulnerable to the effects of teratogens is considered to be between weeks 2 to 8 of pregnancy. This period is known as the embryonic period, during which the organs and major body systems are forming. Exposure to teratogens during this time can lead to structural abnormalities or birth defects. It is crucial for women to be aware of this critical window of susceptibility during preconception counseling to avoid potential harm to the developing fetus.
How should the nurse interpret the results of a study comparing incidence of sexually transmitted diseases between two populations?
- A. Because the CI of the RR includes the value of 1, the difference between the groups is meaningless.
- B. A 95% confidence interval is a statistically significant finding.
- C. A relative risk of 0.80 is moderately powerful.
- D. Because there is no P value reported for the CI, the nurse is unable to make any conclusions about the data.
Correct Answer: A
Rationale: If the confidence interval includes 1, the difference is not statistically significant.
To prevent breast engorgement a new breastfeeding mother should be instructed to:
- A. Apply cold packs to the breast before feeding
- B. Breastfeed frequently and for adequate lengths of time to empty the breasts.
- C. Limit her intake of fluids for a few days
- D. Feed her infant no more than every 4 hours
Correct Answer: B
Rationale: Frequent breastfeeding helps prevent engorgement.
A nurse is admitting a client who is at 35 weeks of gestation and is experiencing mild vaginal bleeding due to placenta previa. Which of the following actions should the nurse plan to take?
- A. Initiate continuous monitoring of the FHR.
- B. Administer a dose of betamethasone.
- C. Check the cervix for dilation every 8 hr.
- D. Request that the provider prescribe misoprostol PRN.
Correct Answer: A
Rationale: In placenta previa, the placenta partially or completely covers the cervix, which can lead to vaginal bleeding. Continuous monitoring of the fetal heart rate (FHR) is crucial in this situation to assess the well-being of the fetus. Any signs of distress or changes in the FHR can indicate potential complications, such as fetal hypoxia. This monitoring allows for prompt intervention if necessary to ensure the safety of both the mother and the baby. Administering betamethasone may be indicated to promote fetal lung maturity in cases of anticipated preterm birth, but it is not the priority in this scenario where monitoring the fetal well-being is crucial. Checking the cervix for dilation every 8 hours is not necessary and may increase the risk of further bleeding. Misoprostol, a medication used to induce labor, is contraindicated in cases of placenta previa because it can cause further
