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 wear scrotal support for at least 48 hours after the procedure to decrease pain and swelling, and protect the wound.
Some possible explanations for the other choices are:
- Choice A is wrong because the client should avoid sexual activity for at least 1 week, not 4 weeks, after the procedure.The client will not be sterile right away and will need to use another form of birth control until the sperm count is zero.
- Choice C is wrong because the client should apply ice packs to the scrotum for at least 2 days, not 72 hours, after the procedure.Ice helps prevent tissue damage and decrease swelling and pain.
- Choice D is wrong because the client should not take aspirin for pain relief after the procedure, as it can increase the risk of bleeding.The client can take nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen instead.
Correct Answer is B
Explanation
The correct answer is choice B. The nurse should advise the client to take the pill at bedtime or with food.This can help reduce nausea, which is a common side effect of COCs.Nausea usually diminishes with continued use of the same method.
Choice A is wrong because taking the pill with a glass of water on an empty stomach may increase nausea.
Choice C is wrong because switching to a different brand of COCs is not effective in treating nausea.There are no significant differences among various COCs in terms of nausea.
Choice D is wrong because stopping the pill and using another method of contraception is not necessary unless the client prefers it.Nausea is not harmful and can be managed with simple measures.
