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. The implant will cause heavy menstrual bleeding.
- B. The implant may cause irregular bleeding patterns, including light spotting.

A patient who has an LNG-IUC in place calls the office and states she just took a pregnancy test, and it is positive. She comes in for a visit, and the nurse does another pregnancy test, which is positive. What does the nurse know that the clinician will inform the patient regarding the IUC?
- A. Removing the IUC may increase the chance of infertility.
- B. The fetus is at risk for congenital defects.
- C. The IUC needs to be removed regardless of the plans for this pregnancy.
- D. There is no risk to the fetus if the IUC is left in place.
Correct Answer: D
Rationale: The correct statement the nurse knows that the clinician will inform the patient regarding the LNG-IUC is that there is no risk to the fetus if the IUC is left in place. The LNG-IUC (levonorgestrel-releasing intrauterine system) is a highly effective form of contraception that works by releasing progesterone locally in the uterus. The hormonal effect of the LNG-IUC is mostly limited to the uterus and very little of it circulates systemically. Therefore, there is no known increased risk of congenital defects or harm to the fetus if the IUC is left in place during pregnancy. The IUC can be left in place if the patient chooses to continue the pregnancy, provided there are no signs of infection or other complications that would necessitate its removal.
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 is educating an adolescent patient about Depo-Provera. Which statement should be included in this teaching session?
- A. You only need to come in every 5 months to get each injection.
- B. You may lose weight on this medication, so make sure to maintain a well-balanced diet.
- C. You may experience heavy bleeding or spotting monthly or none at all.
- D. You will not be able to start this medication until you have been pregnant at least once.
Correct Answer: C
Rationale: Depo-Provera can cause irregular bleeding patterns, including spotting or no bleeding at all. Choice A is incorrect because Depo-Provera needs to be administered every 3 months, not every 5 months. Choice B is incorrect as weight gain is more commonly associated with Depo-Provera, not weight loss. Choice D is incorrect as Depo-Provera can be used regardless of whether the woman has been pregnant before.
A nurse is giving post-op teaching to a person after a surgical abortion. What education should be provided?
- A. Report bleeding that is heavy, soaks more than two pads per hour for 2 hours.
- B. You can resume vaginal coitus the next day.
- C. You do not need to return to the clinic for follow-up.
- D. You should use tampons if your bleeding is heavy.
Correct Answer: A
Rationale: It is important for the nurse to educate the person who has undergone a surgical abortion about the signs of a possible complication, such as heavy bleeding. The instruction to report bleeding that is heavy, where the individual soaks more than two pads per hour for 2 hours, is crucial as it can indicate excessive bleeding that may require medical attention. Immediate reporting of such heavy bleeding can help prevent complications and ensure proper medical intervention.
