What should the nurse do if a client experiences a sensation of warmth during cardiac catheterization?

When a client experiences a sensation of warmth during cardiac catheterization, it is typically due to the contrast dye being injected into the bloodstream. This is a common and expected reaction as the dye travels through the vascular system, creating a feeling of warmth in areas where it circulates. Reassuring the client that this sensation is normal helps to alleviate anxiety and allows the procedure to continue smoothly.

It's important for the healthcare provider to validate the client’s experiences while ensuring that they are aware of what to expect during the procedure. This reassurance can enhance the client’s comfort and cooperation. If the client expresses additional concerns or experiences adverse symptoms beyond the typical warmth, further assessment and action would be warranted.

In contrast, stopping the procedure or notifying the physician immediately might be appropriate in cases of severe adverse reactions, but warmth alone does not constitute an indication for such measures. Other interventions like providing oxygen or applying cold compresses are not necessary for a normal warm sensation related to the contrast dye.
