A nurse is assessing a client immediately following a cardiac catheterization. The nurse should notify the provider for which of the following findings?

A. Mild discomfort at the insertion site is expected following a cardiac catheterization. It should be monitored, but it is not a concern unless it worsens or is accompanied by other signs of complications. B. Bounding pulses may indicate increased blood flow and may not necessarily be a concern. However, they should be monitored for any changes. C. A heart rate of 90/min is within the normal range for many clients post-procedure and is not an immediate cause for concern. D. A hematoma at the insertion site could indicate bleeding or a clot and may require urgent intervention to prevent further complications such as ischemia or hemorrhage.
