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

Choice A rationale:Checking the femoral site for hematoma formation is the most appropriate action in response to the client's complaint of pain at the right groin insertion site after a cardiac catheterization. Hematoma formation is a potential complication of this procedure and can lead to further complications if not addressed promptly. Checking for hematoma allows the nurse to assess for bleeding and take appropriate measures to manage it.Choice B rationale:Stimulating the client to take deep breaths is not the most immediate action needed in this situation. While deep breathing is important for respiratory function, the client's pain at the groin site requires immediate assessment to rule out complications.Choice C rationale:Evaluating the integrity of the IV insertion site is not the primary concern in this case. The client's pain is localized to the groin site, which is where the cardiac catheterization was performed. Checking for hematoma formation at this site takes precedence.Choice D rationale:Assessing distal lower extremity capillary refill is important for assessing peripheral perfusion, but it is not the most immediate action needed when a client complains of pain at a specific site, such as the right groin insertion site after a cardiac catheterization. Checking for hematoma and assessing for bleeding should come first.
