Sample Nursing Research Paper on Plan B

Plan B is the pill form of Levonorgestrel, which is a synthetic form of the naturally occurring hormone, progesterone. The hormonal medication is used as an emergency birth control method that acts in three different ways to prevent pregnancy. The first step in its action is blocking the sperms from passing into the uterus and through to the fallopian tubes where fertilization takes place as it causes the thickening of the mucus layer around the cervix. The second step involves inhibiting ovulation by restraining the ability of the hypothalamus to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The third step involves its ability to inhibit the implantation of the fertilized egg on the uterine walls. Therefore, it prevents pregnancies by preventing the already fertilized egg from growing into a full-formed embryo (WebMed, 2018; Editors, n.d).

Plan B is taken by women who have had unprotected sex or those who are victims of failures of birth control measures. However, it must be taken within 72 hours after such incidences. To increase its effectiveness, it should be taken within the shortest time possible after an emergency intercourse incident. Effectiveness also reduces for individuals who vomit within the first two hours of taking the pill. It is a one-pill dose that is used for emergency and is not a substitute for regular birth control measures. Individuals who are allergic to the synthetic compound should not use Plan B as it may lead to an adverse allergic reaction. It is a low-cost way of preventing pregnancies as the pill costs between $15 and $50 depending on the outlet where it is purchased. In some cases, individuals can get it for free (Planned Parenthood, 2018; Editors, n.d).
