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

Answer and Explanation

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. Increased serum potassium level.Oral contraceptives can affect the levels of various electrolytes in the blood, such as sodium, potassium, calcium and magnesium.According to one study, oral contraceptives can increase the levels of serum copper, iron, calcium and cadmium, and decrease the levels of serum zinc, selenium, phosphorus and magnesium.

Therefore, a high serum potassium level can indicate an adverse effect of oral contraceptives on this client.

Choice A is wrong because oral contraceptives do not decrease serum glucose level.In fact, they can increase the plasma glucose level and insulin response, which can impair glucose tolerance and increase the risk of diabetes.

Choice C is wrong because oral contraceptives do not decrease serum triglyceride level.On the contrary, they can increase the fasting triglyceride level by 13 to 75 percent, which can elevate the risk of cardiovascular disease.

Choice D is wrong because oral contraceptives do not increase serum protein level.They can increase the levels of some apolipoproteins, such as A-I, A-II and B, but these are not the same as total protein.

A. “It releases hormones that thicken cervical mucus and prevent ovulation.”. B. “It creates a local inflammatory response that impairs implantation.”. C. “It alters tubal motility and interferes with sperm transport.”. D. All of the above

Correct Answer is B

Explanation

The correct answer is choice B. It creates a local inflammatory response that impairs implantation.This means that the IUD makes the lining of the uterus less suitable for a fertilized egg to attach to it.

Choice A is wrong because it describes how hormonal IUDs work, not copper IUDs.Hormonal IUDs release hormones that thicken cervical mucus and prevent ovulation.

Choice C is wrong because it describes how tubal ligation works, not IUDs.Tubal ligation is a surgical procedure that blocks or cuts the fallopian tubes, which prevents sperm from reaching an egg.

Choice D is wrong because it implies that all of the above choices are correct, which they are not.

Only choice B is correct for copper IUDs.
