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 as the client’s pain at the groin insertion site could indicate bleeding or hematoma formation, which requires immediate attention.B. Evaluating the IV insertion site is important but does not directly address the pain at the groin site.C. Stimulating the client to take deep breaths helps with respiratory function but does not address the potential complications at the groin site.D. Assessing distal lower extremity capillary refill is useful for overall circulation but is not the immediate concern in this situation.
