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 sensation is common during cardiac catheterization due to the injection of contrast dye. This feeling is typically brief and harmless, and clients should be reassured that it is an expected part of the procedure. B. Numbness and tingling of the extremities: These symptoms may indicate compromised circulation or nerve involvement and are not expected during the procedure. If they occur, they require immediate assessment and intervention. C. Increased salivation: Increased salivation is not associated with cardiac catheterization. It could suggest a reaction to medication or another unrelated issue, but it is not a normal response during this procedure. D. Headache: Headaches are not expected during cardiac catheterization. If a client develops a headache, it could be related to contrast dye sensitivity, blood pressure changes, or anxiety, and would require further evaluation.
