Before a client undergoes a CT scan with contrast, what should the nurse confirm?

• A. Reassess the client's allergies
• B. Confirm that a signed consent is in the chart
• C. Ensure the client is well-hydrated
• D. Ask the client to remove all metal jewelry

Answer: (D)

In preparation for a CT scan with contrast, it is essential for the nurse to ask the client to remove all metal jewelry. Metal objects can interfere with the imaging process by causing artifacts on the CT scan, which may obstruct or distort the images and lead to inaccurate interpretations. By ensuring that all metal jewelry is removed, the nurse helps to promote optimal conditions for the scan, allowing for clear and precise imaging. While reassessing the client's allergies is important – particularly to avoid adverse reactions to the contrast material – and confirming that a signed consent is documented is critical for legal and ethical reasons, the immediate concern before the scan itself revolves around ensuring that the scan can be performed without interference. Hydration is also vital, particularly if the contrast used requires renal clearance; however, the specific action of removing metal jewelry directly addresses the integrity of the imaging.
