Q1. What is the failure rate of combined oral contraceptives (COCs)
with perfect use vs. typical use?
Answer: Perfect use: 0.3%; typical use: approximately 7% per year.
Rationale: The gap reflects that COC efficacy is highly user-dependent
(e.g., missed pills), unlike LARC methods .
Q2. Which contraceptive method has the lowest failure rate and
requires the least user compliance?
Answer: Long-acting reversible contraception (LARC) — etonogestrel
implant and IUDs, with failure rates under 1%.
Rationale: LARC methods do not rely on daily user action, eliminating
user error .
Q3. What is the primary mechanism of action of combined oral
contraceptives?
Answer: Suppression of ovulation via inhibition of the hypothalamic-
pituitary-ovarian axis.
Rationale: Estrogen suppresses FSH while progestin suppresses the LH
surge, blocking ovulation .
Q4. Name absolute contraindications to combined estrogen-
containing contraceptives (US MEC Category 4).
Answer: History of VTE/PE, known thrombogenic mutations, migraine
,with aura, uncontrolled hypertension, smoking ≥15 cigarettes/day in
women over 35, current breast cancer, ischemic heart disease, and
history of stroke .
Q5. A 38-year-old smoker (20 cigarettes/day) requests the
combined pill. What should the provider do?
Answer: Decline combined estrogen-containing contraception (US MEC
Category 4) and offer a progestin-only method instead.
Rationale: Age >35 combined with heavy smoking synergistically raises
MI and stroke risk with estrogen use .
Q6. What is the mechanism of action of the levonorgestrel IUD
(Mirena)?
Answer: Thickens cervical mucus, causes endometrial thinning, and
impairs sperm function.
Rationale: Acts locally; most women continue to ovulate, but pregnancy
remains rare due to endometrial and cervical mucus barriers .
Q7. What is the most common side effect of the copper IUD
(ParaGard)?
Answer: Heavier menstrual bleeding and increased dysmenorrhea,
especially in the first few months.
Rationale: Copper ions incite a sterile local inflammatory reaction,
increasing prostaglandin release .
Q8. How does the copper IUD work as a contraceptive?
Answer: It creates a local inflammatory/spermicidal reaction toxic to
sperm and ova, preventing fertilization .
Q9. What is the recommended duration of use for the etonogestrel
implant (Nexplanon)?
Answer: Up to 3 years.
Rationale: Efficacy is maintained for 3 years; replacement is
recommended after this period .
Q10. A female should be told to take her OCP at bedtime if she
experiences which side effect?
Answer: Nausea.
,Rationale: Taking OCPs at bedtime can reduce gastrointestinal side
effects; nausea is often transient .
Q11. List common side effects of depot medroxyprogesterone
acetate (DMPA/Depo-Provera).
Answer: Irregular bleeding or amenorrhea, weight gain, delayed return
to fertility, and bone mineral density loss with prolonged use .
Q12. What counseling point is important regarding DMPA and bone
density?
Answer: There can be a reversible decrease in bone mineral density with
long-term use, though it is not an absolute contraindication.
Rationale: Studies show bone density loss is largely regained after
discontinuation .
Q13. What is the appropriate follow-up interval for DMPA
injections?
Answer: Every 11–13 weeks (every 3 months).
Rationale: This interval maintains serum progestin levels above the
threshold needed to suppress ovulation .
Q14. A patient wants to start COCs and has migraine without aura.
Is this a contraindication?
Answer: No — migraine without aura is US MEC Category 2; migraine
WITH aura is Category 4 (contraindicated).
Rationale: Aura reflects transient cortical vasospasm, and estrogen can
potentiate vascular events .
Q15. What is the Quick Start method for initiating hormonal
contraception?
Answer: Starting the method the same day as the office visit after a
negative pregnancy test, with backup contraception for 7 days .
Section 2: Gynecologic Conditions & Disorders
Q16. What is the average age of menopause onset in the United
States?
, Answer: Approximately 51 years of age.
Rationale: Menopause is defined as 12 consecutive months of
amenorrhea without another pathologic cause .
Q17. Which hormone is responsible for ovulation and the
development of the corpus luteum?
Answer: Luteinizing hormone (LH).
Rationale: The mid-cycle LH surge triggers ovulation and promotes
corpus luteum development .
Q18. Patients with polycystic ovarian syndrome (PCOS) are at higher
risk for developing which of the following?
Answer: Type 2 diabetes.
Rationale: PCOS is associated with insulin resistance, significantly
increasing the risk of developing type 2 diabetes .
Q19. Which one of the following is NOT a pathological characteristic
of PCOS?
Answer: Decreased LH/FSH ratio.
Rationale: PCOS is characterized by an elevated LH/FSH ratio (typically
>2:1) .
Q20. PCOS is associated with clinical findings of obesity due to:
Answer: Hyperinsulinemia.
Rationale: Insulin resistance and resulting hyperinsulinemia promote
weight gain and metabolic disturbances in PCOS .
Q21. A woman presents with irregular menses, hirsutism, and
obesity. What is the first-line diagnostic test for suspected PCOS?
Answer: Serum testosterone.
Rationale: Hyperandrogenism is a hallmark of PCOS; measuring serum
testosterone helps confirm elevated androgen levels .
Q22. Which hormone increases during the follicular phase of the
menstrual cycle to prepare the uterus for ovum fertilization?
Answer: Estrogen.
Rationale: Estrogen rises during the follicular phase and promotes
endometrial proliferation .
