An LPN/VN is preparing to administer a scheduled dose of regular insulin 6 units subcutaneously to a 68-year-old male resident of a long-term care facility who has type 2 diabetes mellitus and osteoarthritis. The order reads "Regular insulin 6 units subcutaneously now, before breakfast, for glucose 200-250 mg/dL." The morning fingerstick glucose is 238 mg/dL. Vital signs are BP 132/78 mmHg, HR 76 bpm, RR 16/min, temp 98.4°F. Before giving the insulin, the resident mentions he has been taking his daughter's ibuprofen "a few times this week" for knee pain because his own pain medication ran out. The chart lists a documented allergy to naproxen (hives) and an active order for warfarin 5 mg daily, with an INR of 2.6 reported yesterday. Which action should the nurse take before administering the insulin?
- Chart the ibuprofen use in the nursing notes and continue preparing the insulin dose, without reporting the interaction risk to the RN or prescriber.
- Report the resident's unsupervised ibuprofen use and its interaction risk with warfarin before proceeding.
- Recheck the fingerstick glucose 30 minutes after giving the insulin to confirm the response.
- Hold today's warfarin dose independently because the INR of 2.6 is outside normal range.
