A client is scheduled for a cardiac catheterization. Following the procedure, the nurse should: A. Assess for allergy to iodine B. Check pulses proximal to the site C. Assess the urinary output D. Check to ensure that the client has a consent form signed

Cardiac catheterization is a medical procedure used to diagnose and treat certain heart conditions. It involves the insertion of a thin, flexible tube (catheter) into a blood vessel, usually in the groin or arm, and then guiding it to the heart. Various tests and treatments can then be performed using the catheter. Understanding the procedure will help us determine the appropriate nursing actions to be taken afterward.

Now, let's analyze each option, taking into consideration the common concerns and potential complications after a cardiac catheterization: A. Assess for allergy to iodine: Before the procedure, contrast dye containing iodine is sometimes used to take X-ray images of the blood vessels. However, assessing for iodine allergies should ideally be done before the procedure to prevent any reactions. B. Check pulses proximal to the site: After the procedure, it is important to monitor the patient's circulation in the affected limb. Checking pulses proximal (closer to the heart) to the catheter insertion site can help to ensure proper blood flow and detect any complications, such as arterial blockages or blood clots. C. Assess the urinary output: While monitoring urine output is important for certain patients, especially those with heart failure or kidney problems, it is not specific to post-cardiac catheterization care. D. Check to ensure that the client has a consent form signed: Obtaining a signed consent form should be done before the procedure takes place, not afterward.

Given our analysis, option B (checking pulses proximal to the catheter insertion site) is the most appropriate nursing action to be taken following a cardiac catheterization, as it directly pertains to potential complications related to the procedure (such as arterial blockages or blood clots) and helps to ensure proper circulation in the affected limb.
