Which of the following best describes the mechanism of action of birth control pills?
- A. They block sperm from reaching the egg.
- B. They prevent ovulation by suppressing hormone levels.
- C. They increase cervical mucus production to block sperm entry.
- D. They reduce the size of the ovaries and fallopian tubes to prevent pregnancy.
Correct Answer: B
Rationale: Birth control pills primarily work by preventing ovulation, thereby inhibiting the release of eggs for fertilization. Choice A is incorrect because birth control pills do not directly block sperm; they prevent ovulation. Choice C is partially correct but is not the main mechanism, as the primary function is to prevent ovulation. Choice D is incorrect because birth control pills do not alter the size of reproductive organs.

A patient calls and says she used her diaphragm on Saturday night at 8:00 p.m., again on Sunday morning at 2:00 a.m., and again at 8:00 a.m. She is wondering when she can safely remove it while still having effective contraception. What is the nurse’s best response?
- A. 10:00 a.m. Sunday
- B. 2:00 p.m. Sunday
- C. 10:00 p.m. Sunday
- D. 8:00 a.m. Monday
Correct Answer: D
Rationale: In general, a diaphragm should be left in place for at least 6 hours after intercourse but no more than 24 hours. Based on the patient's usage times on Saturday night at 8:00 p.m., Sunday morning at 2:00 a.m., and Sunday morning at 8:00 a.m., she can safely remove the diaphragm on Monday morning at 8:00 a.m. This ensures she has used it for the necessary timeframe for effective contraception.
The nurse assesses a patient for medical eligibility for contraceptive use. What is the meaning of an MEC score of 1?
- A. There is no restriction for the use of the contraceptive method.
- B. There is an unacceptable health risk if the contraceptive method is used.
- C. There is a risk that outweighs the advantages of the contraceptive method.
- D. There is an advantage of using a contraceptive method that outweighs any risk.
Correct Answer: A
Rationale: In the context of medical eligibility for contraceptive use, an MEC (Medical Eligibility Criteria) score of 1 indicates that there are no restrictions for using the particular contraceptive method. A score of 1 suggests that the advantages of using the contraceptive method outweigh any potential risks, making it a safe and recommended choice for the patient. Therefore, a patient with an MEC score of 1 can use the contraceptive method without any concerns regarding health risks or restrictions.
A 23-year-old female patient is considering intrauterine device (IUD) contraception. What is the most important information to assess before placement?
- A. Is there any family history of heart disease?
- B. Are you allergic to any metals?
- C. Have you had any previous IUDs inserted?
- D. Do you have a history of hypertension?
Correct Answer: B
Rationale: The IUD may contain metal components, and it's crucial to check for any metal allergies before placement. Choice A, family history of heart disease, is not directly related to IUD use. Choice C is incorrect because previous IUD insertion is not as crucial as identifying an allergy to the materials in the IUD. Choice D is incorrect because hypertension is not a contraindication for IUD use, though it should be monitored.
A 26-year-old woman is interested in using an IUD for contraception. What is the primary advantage of using an IUD over other contraceptive methods?
- A. It requires no daily action from the patient once inserted.
- B. It provides immediate protection after insertion.
- C. It is effective immediately after the first sexual activity after insertion.
- D. It is effective only for 6 months before needing replacement.
Correct Answer: A
Rationale: One of the primary advantages of the IUD is that it requires no daily action, making it a convenient and reliable method. Choice B is incorrect because it may take a few days for some types of IUDs to provide full protection. Choice C is incorrect because immediate protection may not be ensured immediately after insertion, especially for hormonal IUDs. Choice D is incorrect because IUDs typically last for several years, not just 6 months.
A 28-year-old patient has decided to use the patch contraception. The nurse is educating her on the best site to use. Where is the best place to put the patch? Select one that does not that apply.
- A. Buttocks
- B. Leg
- C. Breast
- D. Arm
Correct Answer: C
Rationale: The best sites for applying the contraceptive patch are the buttocks, arm, and leg. These areas have sufficient fat and are away from areas that might rub off the patch. Choice B (Neck) is incorrect as the neck is not recommended for patch application due to the potential for irritation and the high blood flow area. Choice C (Breast) is not recommended because the breast tissue may affect the adhesion of the patch.
