A nurse in a clinic is reinforcing teaching with a client who has a new prescription for a combination contraceptive transdermal patch. Which of the following should the nurse include in the teaching?

A. "The contraceptive effect will continue for 6 months following discontinuation of the medication.": The contraceptive effect of the transdermal patch does not persist after discontinuation. Fertility generally returns quickly, often within a few days to a month, so this statement is inaccurate and could lead to unintended pregnancy. B. "Start the first patch on the seventh day of the menstrual cycle.": Standard instructions recommend applying the first patch on the first day of menstruation or on the first Sunday after menstruation begins. Starting on the seventh day could reduce contraceptive effectiveness and increase the risk of ovulation. C. "Apply the patch to the lower abdomen.": The patch can be applied to the lower abdomen, buttocks, back, or upper arm, avoiding breasts. Correct placement ensures consistent absorption of hormones and optimal contraceptive effectiveness, making this an essential part of client teaching. D. "Expect to have a headache during the first month.": While some clients may experience headaches as a side effect of estrogen-containing contraceptives, it is not a guaranteed or expected symptom. Teaching should focus on common, likely side effects rather than implying all clients will experience this.
