Question 4 of 5

An 80-year-old woman with background history of Type 2 Diabetes, hypertension and mild renal impairment is admitted with symptoms of haemoptysis and pleuritic chest pain. She is suspected to have a pulmonary embolism and a CT pulmonary angiogram is booked. She normally takes Metformin 500 mg TDS. What advice would you give her regarding metformin?

Suspend metformin for 48 hours before and for 48 hours after the test and start at a lower dose if renal function has returned to the baseline C. Suspend metformin for 48 hours prior to the test and restart immediately after if the renal function is returned to baseline D.

Question 5 of 5

A patient has a history of chronic iron deficiency anemia requiring a recent blood transfusion. She has undergone an extensive GI work-up including upper endoscopy, colonoscopy, capsule enteroscopy, and abdominal CT scan. Her only medications are ferrous sulfate, baby aspirin, COX II inhibitor, and HCTZ. Which statement is true?

A. A dedicated small bowel series has a high likelihood of being positive B. 81 mg of aspirin per day decreases the benefit of using a COX II inhibitor C. The patient should have a provocative arteriogram with heparin infusion to identify the source of blood loss D. Hormonal therapy has been shown to be effective in decreasing blood loss due to arteriovenous malformations

Correct Answer: B

Rationale: Dedicated small bowel series is typically of low yield in the diagnostic evaluation of chronic iron deficiency anemia. Provocative arteriograms have been performed in patients with gastrointestinal hemorrhage of obscure origin, but only a small series of cases have been reported, and it remains to be determined if this therapy can truly be done safely with a significant diagnostic yield. Hormonal therapy has been given to patients with arteriovenous malformations, but a randomized controlled trial published in 2001 showed no benefit using ethinyl estradiol and norethisterone in reducing recurrent bleeding in patients with angiodysplasia. It is important to recognize that even a baby aspirin a day can decrease the benefit in mucosal protection gained from using a COX II selective inhibitor.
