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?

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.

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.

Correct Answer: B

Rationale: One difference between the copper IUC and the LNG-IUC is their placement in the uterus. The copper IUC, also known as the copper intrauterine device (IUD), is a small, T-shaped device that is inserted into the uterus by a healthcare provider. On the other hand, the LNG-IUC, or levonorgestrel-releasing intrauterine system, is also a T-shaped device but it releases a hormone called levonorgestrel into the uterus. Both devices are placed within the uterus, but the LNG-IUC releases hormones while the copper IUC relies on the copper to provide contraception.

Correct Answer: A

Rationale: Emergency contraception is most effective when taken within 72 hours of unprotected sex. Choice B is incorrect as it is not as effective after 5 days. Choice C is incorrect because emergency contraception works primarily by preventing ovulation, not by preventing implantation. Choice D is incorrect because most emergency contraception methods are available over the counter.

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.
