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?

Rationale: A. Increased salivation: Increased salivation is not an expected effect of cardiac catheterization. It may indicate a reaction to medication or anxiety but is not directly associated with the procedure. B. Headache: While headaches can occur with some cardiac medications or contrast agents, they are not typical or expected during catheterization itself. Persistent headaches should be reported and evaluated further. C. Sensation of skin warmth: A warm or flushed sensation is a common and expected finding during cardiac catheterization due to the injection of contrast dye. Patients are typically informed in advance to reduce alarm. D. Numbness and tingling of the extremities: These sensations may suggest compromised circulation or nerve involvement, which is not expected and should be promptly reported. It could indicate a complication from arterial access.
