Final answer:
The finding that a nurse should report to a provider prior to coronary angiography is an allergy to shellfish or iodine, as the contrast dye used in the procedure may trigger an allergic reaction.
Step-by-step explanation:
A nurse preparing a client for a coronary angiography should report an allergy to shellfish or iodine to the provider prior to the procedure. This is because the contrast dye used in the procedure commonly contains iodine, which can cause a severe allergic reaction in patients with such allergies. Mild dizziness, recent flu-like symptoms, and occasional numbness in the feet may not be as immediately concerning, but they should still be documented and discussed with the provider to ensure overall safety and to consider any potential impact on the patient’s health during the angiography.
