Prior to a cardiac catheterization, what is the most important action for the nurse to take?
Correct Answer: D
Rationale: The correct answer is D: Assess the client for any allergies, especially to iodine or shellfish. This is crucial because contrast dye containing iodine is commonly used during cardiac catheterization, and a client with allergies to iodine or shellfish can have a severe allergic reaction. It is essential to identify allergies beforehand to prevent any potential adverse reactions during the procedure.
A: Ensuring NPO status is important for some procedures, but assessing for allergies is more critical to prevent life-threatening reactions.
B: Administering pre-procedure medications is important, but assessing for allergies takes precedence to avoid allergic reactions.
C: While obtaining informed consent is necessary, assessing for allergies is a crucial safety measure to prevent allergic reactions during the procedure.
