What expected response should the nurse monitor after a cardiac catheterization?

After a cardiac catheterization, one of the expected responses that the nurse should monitor for is a marked increase in the volume of urine output. This occurs due to improved renal perfusion resulting from enhanced cardiac function and blood flow after addressing any blockages or abnormalities. Additionally, during the procedure, contrast agents may be used, and a well-functioning heart that is efficiently pumping blood can contribute to a better glomerular filtration rate, hence increasing urine production.

Monitoring for this increase is crucial, as it indicates that the kidneys are receiving adequate blood flow and are functioning well post-procedure. This response can also serve as an indirect indicator of the patient’s overall hemodynamic status after the intervention.

In contrast, a decrease in blood pressure, complaints of discomfort, or respiratory distress are not expected findings following a successful cardiac catheterization.
