A nurse is providing teaching to a client who is to undergo a cardiac catheterization. Which of the following findings is expected during the procedure?

A. Sensation of skin warmth. A warm or flushed sensation is common during cardiac catheterization, especially when contrast dye is injected. This is a normal and temporary response to the dye used in the procedure. B. Increased salivation. Increased salivation is not a typical reaction during cardiac catheterization. It is not associated with the administration of contrast dye or catheter manipulation. C. Numbness and tingling of the extremities. Numbness or tingling may indicate compromised circulation or nerve involvement, which is abnormal and should be reported immediately. It may suggest complications like arterial spasm or clot. D. Headache. Headaches are not expected during a cardiac catheterization. If a headache occurs, especially a severe one, it should be evaluated further, as it could indicate a reaction or another complication.
