A nurse is providing education to a patient about the use of intrauterine devices (IUDs).

Which of the following statements made by the patient indicates a need for further teaching?

The correct answer is choice D. The client should switch to a higher-dose formulation of oral contraceptives.Breakthrough bleeding is a common side effect of low-dose birth control pills, especially in the first months of use.It may indicate that the estrogen dose is too low to suppress the growth of the endometrium.

A higher-dose formulation may reduce or eliminate breakthrough bleeding by providing more estrogen.

Choice A is wrong because taking two pills daily until bleeding stops is not a recommended way to manage breakthrough bleeding.

It may cause side effects such as nausea, headache, or breast tenderness.It may also increase the risk of blood clots.

Choice B is wrong because stopping oral contraceptives immediately is not advisable unless there is a medical reason to do so.

Stopping oral contraceptives may cause irregular bleeding, ovulation, and pregnancy.

The client should consult with their provider before discontinuing any medication.

Choice C is wrong because smoking does not cause breakthrough bleeding, but it does increase the risk of serious complications from oral contraceptives, such as stroke, heart attack, or blood clots.The client should avoid smoking while taking any hormonal contraceptive, regardless of whether they experience breakthrough bleeding or not.

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.
