The nurse is counseling a woman who wants to become pregnant. The woman tells the nurse that she has a 28-day menstrual cycle and the first day of her menstrual period was January 8. The nurse correctly calculates that the woman's next fertile period is?
February 6-7
January 22-23
January 30-31
January 14-15
The Correct Answer is B
Choice A: February 6-7 is incorrect. This is too late for the woman's fertile period, which occurs around the time of ovulation. Ovulation usually happens about 14 days before the next period starts, which would be around January 22 for a 28-day cycle¹.
Choice B: In a 28-day menstrual cycle, ovulation typically occurs around day 14 (counting from the first day of the last menstrual period). Since the first day of the last period is January 8, day 14 falls on January 22. The fertile window consists of the five days leading up to ovulation and the day of ovulation (January 17–22), as sperm can survive in the reproductive tract for up to 5 days, and the egg remains viable for about 24 hours after ovulation. January 22-23 is the most fertile period, with ovulation occurring around January 22 and the egg remaining viable for fertilization on January 23.
Choice C: January 30-31 is incorrect. This is after the woman's fertile period, which ends about a day after ovulation. Ovulation usually happens about 14 days before the next period starts, which would be around January 22 for a 28-day cycle.
Choice D: January 14-15 corresponds to cycle days 7-8, which is too early for ovulation in a typical 28-day cycle. Ovulation generally occurs around day 14 (January 22). The follicular phase (the first half of the cycle) is when the follicles in the ovary mature, and estrogen levels rise to trigger ovulation. At this point (January 14-15), the egg is not yet released, and the uterus is still preparing for ovulation, making conception unlikely.

Correct Answer is B
Explanation
Choice A reason: Human immunodeficiency virus (HIV) is a viral sexually transmitted infection that causes acquired immunodeficiency syndrome (AIDS). It is characterized by a progressive decline of the immune system, leading to opportunistic infections and cancers. It does not have recurrent episodes, but rather a chronic and incurable course.
Choice B reason: Herpes simplex virus (HSV)-2 is a viral sexually transmitted infection that causes genital herpes. It is characterized by a primary infection followed by recurrent episodes of painful blisters and ulcers in the genital area. The virus remains latent in the nerve cells and can reactivate periodically or in response to triggers such as stress, illness, or menstruation.
Choice C reason: Human papillomavirus (HPV) is a viral sexually transmitted infection that causes genital warts and cervical cancer. It is characterized by a persistent infection that may or may not produce symptoms. It does not have recurrent episodes, but rather a variable and unpredictable course.
Choice D reason: Cytomegalovirus (CMV) is a viral sexually transmitted infection that causes mild or asymptomatic infections in healthy adults. It is characterized by a latent infection that can reactivate in immunocompromised individuals, causing serious complications such as retinitis, pneumonia, or encephalitis. It does not have recurrent episodes, but rather a dormant and opportunistic course.
Correct Answer is D
Explanation
Choice A reason: Quickening is the first perception of fetal movement by the pregnant woman, usually felt between 16 and 20 weeks of gestation. However, quickening can also be confused with gas or peristalsis, which are normal digestive processes that cause sensations in the abdomen.
Choice B reason: Chadwick sign is a bluish discoloration of the cervix, vagina, and vulva due to increased blood flow during pregnancy. It can be observed by the examiner as early as 6 weeks of gestation. However, Chadwick sign can also be caused by pelvic congestion, which is a chronic condition of enlarged and dilated veins in the pelvis².
Choice C reason: Amenorrhea is the absence of menstrual periods, which is one of the most common signs of pregnancy. However, amenorrhea can also be caused by stress, endocrine problems, or other factors that affect the hormonal balance and ovulation.
Choice D reason: Goodell sign is the softening of the cervix due to increased vascularity and edema during pregnancy. It can be palpated by the examiner around 6 to 8 weeks of gestation. Goodell sign is not associated with any other condition besides pregnancy, unlike cervical polyps, which are benign growths of the cervical tissue that can cause bleeding or discharge.
