A nurse is caring for a client and her newborn immediately after delivery. The client's medication history includes prenatal vitamins throughout pregnancy, one or two glasses of wine before knowing she was pregnant, occasional use of an albuterol inhaler in her last trimester, and intravenous morphine during labor. What is the nurse's most appropriate action?

A) This is not a risk of estrogen/progestin therapy. In fact, estrogen/progestin therapy can help prevent osteoporosis and fractures by increasing bone density and strength.

B) This is a possible risk of estrogen/progestin therapy. Some studies have suggested that taking estrogen/progestin therapy for more than five years may increase the risk of ovarian cancer. However, other studies have not found this association

C) This is a serious risk of estrogen/progestin therapy. Estrogen/progestin therapy can increase the risk of blood clots, which can lead to stroke or heart attack. The risk is higher for women who smoke, have high blood pressure, diabetes, or a history of cardiovascular disease.

D) This is not a risk of estrogen/progestin therapy. In fact, some studies have suggested that estrogen/progestin therapy may reduce the risk of colon cancer by lowering inflammation and promoting regular bowel movements.

E) This is another serious risk of estrogen/progestin therapy. Deep vein thrombosis (DVT) is a condition where a blood clot forms in a deep vein, usually in the leg. It can cause pain, swelling, and redness in the affected area. If the clot breaks off and travels to the lungs, it can cause a life threatening condition called pulmonary embolism (PE). Estrogen/progestin therapy can increase the risk of DVT and PE by making the blood more likely to clot

A) Hold metformin 24 hours to 48 hours before the CT. This is correct because it reduces the chance of metformin accumulating in the blood and causing lactic acidosis when combined with the contrast dye.

B) Hold metformin 48 hours after the CT. This is also correct because it allows time for the contrast dye to be eliminated from the body before resuming metformin.

C) Double the metformin dose after the CT. This is incorrect and dangerous because it can cause hypoglycemia, low blood sugar, which can lead to confusion, seizures, coma, or death. D) Take metformin as scheduled the day of the CT. This is incorrect and risky because it can result in high levels of metformin in the blood when mixed with the contrast dye, increasing the likelihood of lactic acidosis.

E) Resume metformin at half dose after the CT. This is incorrect and unnecessary because there is no evidence that reducing the dose of metformin after a CT scan with contrast dye has any benefit or reduces any harm.
