What is the priority nursing intervention for a client after a cardiac catheterization via the brachial artery?

After a cardiac catheterization via the brachial artery, maintaining the client in the supine position is crucial for several reasons. This position helps reduce the risk of bleeding from the catheter insertion site and promotes circulation by alleviating pressure on the access area. By keeping the client supine, it minimizes movements that could disrupt the site and helps ensure that any potential hematoma formation is less likely to occur.

Additionally, this position supports adequate perfusion and allows for easier monitoring of the client’s vital signs, including heart rate and blood pressure, which are essential in assessing any complications that may arise post-procedure. While monitoring vital signs and ensuring oxygen supply are important aspects of post-catheterization care, priority is given to stabilizing the access site, which is best achieved by positioning the client supine.
