How many times per day should the nurse administer this medication? A: Once daily. Medications with long half-lives remain at therapeutic levels longer so are given less frequently. Q: A nurse is caring for a patient taking warfarin. Which food should the nurse instruct the patient to avoid? A: Green leafy vegetables like spinach, kale, and broccoli are high in Vitamin K which antagonizes warfarin's anticoagulant effect. Q: A patient is prescribed metformin for Type 2 diabetes. What should the nurse monitor? A: Renal function (creatinine/BUN) because metformin is contraindicated in renal impairment due to risk of lactic acidosis. ## Study Tips 1.
