A nurse at a family practice clinic receives a call from a client who is prescribed oral contraceptives but forgot to take one dose. The client reports she is in the first week of a 28-day cycle pack. Which of the following instructions should the nurse provide?

A. "Stop taking the pills and switch to a different contraceptive method.": Stopping and switching is not the routine immediate response to a single missed combined pill in week 1; instructions generally focus on taking the missed pill and short-term backup if needed. B. "Take the missed dose now, then continue the medication as ordered.": For a missed combined oral contraceptive pill in the first week, guidance is to take the most recent missed pill as soon as possible (even if that means taking two pills in one day), continue the pack as usual, and use backup contraception or abstain until 7 consecutive days of pills have been taken; emergency contraception may be considered if there was unprotected sex. C. "Take a home pregnancy test.": A pregnancy test is not the immediate action for a single missed pill in week 1 unless there are other indications (for example, missed multiple pills and unprotected intercourse some time earlier) -the immediate step is to take the missed pill. D. "Do not have vaginal intercourse until after your next period.": While abstaining until effective contraception is restored (7 consecutive days of pills) or using backup is recommended, “until after your next period” is unnecessarily restrictive and not the standard instruction.
