A nurse is reviewing the medical record of a client who is requesting an oral contraceptive for birth control. The nurse should identify which of the following findings as a contraindication for the use of oral contraceptives for this client?

Choice A rationale Migraine with aura is considered a Category 4 contraindication (unacceptable health risk) for the use of combined hormonal contraceptives (CHCs), including oral contraceptives. The estrogen component in CHCs increases the risk of ischemic stroke, and this risk is substantially amplified in clients who experience migraine headaches with focal neurological symptoms (aura), necessitating the selection of an alternative birth control method. Choice B rationale Hypotension (low blood pressure) is typically not a contraindication for oral contraceptive use. In fact, some studies suggest a potential, though often clinically insignificant, increase in blood pressure with CHC use due to a potential increase in circulating angiotensinogen, the precursor to the vasoconstrictive hormone angiotensin II. The use of CHCs is not restricted based on hypotension. Choice C rationale Dysmenorrhea (painful menstruation) is often significantly improved or resolved by the use of combined oral contraceptives (COCs). COCs work by suppressing ovulation and thinning the endometrial lining, which typically reduces prostaglandin production, thus decreasing the cramping and pain associated with the menstrual cycle, making it an indication, not a contraindication. Choice D rationale A history of ovarian cysts is generally not a contraindication for combined oral contraceptive use, provided the cysts were non-malignant and resolved or are benign. In fact, COCs can be used to treat or prevent the recurrence of functional ovarian cysts by suppressing the hormonal stimulation of the ovaries that leads to their formation, making it a potential therapeutic benefit.
