A client is recovering in the critical care unit following a cardiac catheterization. IV nitroglycerin and heparin are infusing. The client is sedated but responds to verbal instructions. After changing positions, the client reports pain at the right groin insertion site. Which action should the nurse implement?

A. Checking the femoral site for hematoma formation is crucial because pain at the groin insertion site could indicate bleeding or hematoma formation, which is a potential complication of cardiac catheterization.B. Evaluating the IV insertion site is important but not as directly related to the groin pain as checking the femoral site.C. Stimulating the client to take deep breaths is helpful for respiratory function but does not address the groin pain issue.D. Assessing distal lower extremity capillary refill is important for overall circulation but is not the immediate priority in this scenario.
