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 B
Explanation
The correct answer is choice B. The client should start taking oral contraceptives (OCs) on day one of their menstrual cycle, which is the first day of their period.This way, they will be protected from pregnancy right away and do not need to use a back-up contraceptive method.
Choice A is wrong because starting OCs on Sunday after the period begins may leave a gap of several days when the client is not protected from pregnancy.They would need to use a back-up method for the first seven days of taking OCs.
Choice C is wrong because starting OCs on day five of the menstrual cycle may also leave a gap of unprotected days.The client would need to use a back-up method for the first seven days of taking OCs.
Choice D is wrong because starting OCs on day fourteen of the menstrual cycle is too late and may not prevent ovulation.The client would need to use a back-up method for the first seven days of taking OCs.
