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","E"]
Explanation
The correct answer is choice B and E.Bilateral tubal ligation (BTL) is a permanent form of contraception that involves cutting, tying or blocking the fallopian tubes to prevent pregnancy.It can be performed within 24 hours following childbirthand it is immediately effective.
Choice A is wrong because BTL does not provide protection against sexually transmitted infections (STIs).
People who have BTL should still use condoms to prevent STIs.
Choice C is wrong because BTL does not increase the risk for an ectopic pregnancy.
An ectopic pregnancy is when a fertilized egg implants outside the uterus, usually in the fallopian tube.
BTL prevents fertilization by blocking the passage of eggs and sperm.
Choice D is wrong because BTL does not require abdominal surgery with general anesthesia.
BTL can be done using different methods, such as laparoscopy, minilaparotomy, or hysteroscopy.
These methods use small incisions or no incisions at all and can be done with local or regional anesthesia.
