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?
Inhibiting the production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH)
Increasing the production of prostaglandins that cause uterine contractions
Decreasing the permeability of the fallopian tubes to sperm and egg
Suppressing ovulation, thickening cervical mucus and altering the uterine lining
The Correct Answer is A
The correct answer is choice A. COCs prevent pregnancy by inhibiting the production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are responsible for ovulation.
By suppressing ovulation, COCs prevent the release of a mature egg that can be fertilized by sperm.
Choice B is wrong because COCs do not increase the production of prostaglandins that cause uterine contractions.
Prostaglandins are involved in inflammation and pain, and are not directly related to contraception.
Choice C is wrong because COCs do not decrease the permeability of the fallopian tubes to sperm and egg.
The fallopian tubes are the site of fertilization, and COCs do not affect their function.
Choice D is partially correct but not the best answer. COCs do suppress ovulation, but they also have other mechanisms of action, such as thickening cervical mucus and altering the uterine lining.
These effects make it harder for sperm to reach the egg and for a fertilized egg to implant in the uterus.
Therefore, choice D does not capture the full mechanism of action of COCs.

Correct Answer is C
Explanation
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.
Correct Answer is D
Explanation
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.
