A nurse is teaching a client who is prescribed COCs about the mechanism of action of these pills.

The nurse should explain that COCs prevent pregnancy by?

The correct answer is choice C. OCs can decrease menstrual blood loss and cramps.This is because OCs prevent ovulation and thin the lining of the uterus, which reduces the amount of bleeding and cramping during menstruation.

Choice A is wrong because OCs do not provide protection against STIs.The only contraceptive methods that can prevent STIs are barrier methods, such as condoms.

Choice B is wrong because OCs can have variable effects on libido and sexual satisfaction.

Some women may experience an increase, while others may experience a decrease or no change at all.This depends on individual factors, such as hormone levels, mood, and relationship quality.

Choice D is wrong because OCs can also have variable effects on mood and depression.

Some women may experience an improvement, while others may experience a worsening or no change at all.This also depends on individual factors, such as hormone sensitivity, stress, and history of mental health problems.

The correct answer is choiceD.

All of the above.

Here is why:

• Choice A is correct because obtaining informed consent from the client is a necessary step before any invasive procedure, including IUD insertion.
• Choice B is correct because performing a Pap smear and cervical culture can help screen for cervical cancer and sexually transmitted infections, which are contraindications for IUD use.
• Choice C is correct because administering an analgesic medication can help reduce the pain and discomfort associated with IUD insertion, especially in nulliparous women who have a smaller cervical diameter.
• Choice D is correct because it includes all of the above actions, which are recommended by the American College of Obstetricians and Gynecologists (ACOG) for IUD insertion in nulliparous women.
• Choice A is wrong if it is the only action taken, because it does not address the other aspects of IUD insertion such as screening and pain management.
• Choice B is wrong if it is the only action taken, because it does not ensure the client’s consent and comfort during the procedure.
• Choice C is wrong if it is the only action taken, because it does not verify the client’s eligibility and suitability for IUD use.
