The Correct Answer is C
A. Draw blood specimens for culture and sensitivity: Incorrect. Blood cultures are not routinely required for cardiac catheterization.
B. Administer nitroglycerin 0.4 mg SL 30 min before the procedure: Incorrect. Nitroglycerin is not typically administered before a cardiac catheterization unless specifically ordered.
C. Obtain a CBC with differential: A complete blood count (CBC) is necessary before a cardiac catheterization to assess for potential bleeding risks, infection, or anemia.
D. Transport the client to radiology for a CT scan: Incorrect. Cardiac catheterization is performed in a specialized cardiac catheterization lab, not in radiology.
