A 21-year-old woman complained to her physician of recurrent nausea lasting most of the day. The woman had been suffering from a urinary tract infection presently being treated with ciprofloxacin and from gastroesophageal reflux disease presently being treated with omeprazole. She also routinely took ibuprofen during her menstrual period. One week ago, she started taking a contraceptive pill (ethinyl estradiol and norgestrel). Which of the following drugs most likely caused the patient's nausea?

Correct Answer: C

Rationale: The correct answer is C: Norgestrel. Nausea is a common side effect of contraceptive pills, especially when initially starting them. Norgestrel is a component of the contraceptive pill the patient started one week ago, which aligns with the timing of the onset of her nausea symptoms. Ciprofloxacin and omeprazole are less likely to cause nausea in this case, as the patient has been taking them for some time without issues. Ethinyl estradiol is also a component of the contraceptive pill but is less likely to be the primary cause of the nausea compared to norgestrel.
