Drugs Affecting the Female Reproductive System Quizlet Exam Questions
Question 1 of 5
The most popular form of hormonal contraception is:
Correct Answer: A
Rationale: The correct answer is A: Combined estrogen + progestin oral pill. This form of hormonal contraception is the most popular because it is highly effective in preventing pregnancy by inhibiting ovulation, thickening cervical mucus, and altering the endometrium. It is easy to use, reversible, and offers additional non-contraceptive benefits like reducing menstrual cramps and acne. Phased estrogen + progestin oral pill (B) and postcoital estrogen + progestin pill (C) are not commonly used methods. Depot progestin injection (D) is effective but less popular due to the need for healthcare provider administration and potential side effects like irregular bleeding.
Question 2 of 5
Select the indication for which a progestin is used alone without combining with an estrogen:
Correct Answer: B
Rationale: The correct answer is B: Dysfunctional uterine bleeding. Progestins are used alone for this indication to help regulate the menstrual cycle without the need for estrogen. In dysfunctional uterine bleeding, the endometrium sheds irregularly due to hormonal imbalances. Progestins can help stabilize the endometrium and control bleeding. A: Threatened abortion - Progestins are not typically used alone for this indication as estrogen may also be needed to support the pregnancy. C: Hormone replacement therapy - Progestins are usually combined with estrogen in hormone replacement therapy to protect the uterine lining. D: Premenstrual tension - Progestins alone are not commonly used for this condition, as estrogen may also play a role in managing premenstrual symptoms.
Question 3 of 5
The primary indication of tamoxiphen citrate is:
Correct Answer: C
Rationale: The correct answer is C: Carcinoma breast. Tamoxifen citrate is primarily indicated for the treatment of breast cancer. It is a selective estrogen receptor modulator that helps block the effects of estrogen on breast tissue. This is effective in hormone-receptor-positive breast cancer, helping to reduce the risk of recurrence and improve survival rates. A: Female infertility - Tamoxifen is not indicated for female infertility and can actually cause birth defects. B: Endometrial carcinoma - Tamoxifen use is associated with an increased risk of developing endometrial carcinoma. D: Endometriosis - Tamoxifen is not indicated for the treatment of endometriosis and may worsen the condition. Therefore, the correct answer is C as it aligns with the established use of tamoxifen citrate in the treatment of breast cancer.
Question 4 of 5
The following are functions of progestins, except:
Correct Answer: B
Rationale: The correct answer is B: Stimulate FSH and LH release. Progestins act to inhibit FSH and LH release from the pituitary gland, thus preventing ovulation. Progestins also help prevent uterine contractions, maintain the secretory endometrium, and block ovulation. Therefore, stimulating FSH and LH release would be contradictory to the main function of progestins, making it the incorrect choice.
Question 5 of 5
A 29-year-old woman who was in her 41st week of gestation had been in labor for 12 hours. Although her uterine contractions had been strong and regular initially, they had diminished in force during the past hour. The drug would be administered to facilitate this woman’s labour and delivery is:
Correct Answer: C
Rationale: Rationale: Oxytocin is the correct drug to facilitate labor as it is a hormone that stimulates uterine contractions. It helps to progress labor and delivery. Dopamine (A) is not used for labor induction. Leuprolide (B) is a gonadotropin-releasing hormone agonist, not used for labor. Prolactin (D) is not involved in uterine contractions.
