A nurse is caring for a postoperative patient who is about to receive contrast dye during a diagnostic test. Which finding is most concerning?
Select one:
Slight bruising at the IV insertion site
Blood pressure of 110/72
Metformin on the home medication list
Urine output of 30/ml hr
The Correct Answer is C
A. Mild bruising is a common and usually benign finding at an IV site and not a contraindication to contrast dye administration.
B. This is within normal limits and not concerning before a diagnostic test with contrast.
C. Metformin must be used with caution when a patient is receiving iodinated contrast dye due to the risk of lactic acidosis, especially if the patient develops contrast-induced nephropathy. Typically, metformin is held before and for 48 hours after the procedure until renal function is confirmed to be stable.
D. This is the minimum acceptable urine output and does not by itself contraindicate contrast dye use, though renal function should still be monitored.

Correct Answer is A
Explanation
A. Clients with allergies to bananas, kiwifruit, avocados, and chestnuts are at higher risk for latex allergies due to cross-reactivity. Latex is commonly used in surgical gloves and equipment. Immediate notification of the surgery center allows them to use latex-free supplies and equipment, which is critical for preventing a life-threatening anaphylactic reaction.
B. While food allergies are important, they are not the priority in this surgical context. Preventing exposure to latex during surgery is more urgent and potentially life-saving.
C. This is not the priority action. While antihistamines may help manage minor allergies, latex exposure can cause anaphylaxis, which antihistamines cannot prevent.
D. Reassurance is important, but the critical action is to ensure the surgical team is aware and prepared, not just documentation.
