The statement made by a patient that would delay a scheduled CT scan with contrast would be:
“I have just been started on metformin."
"I am allergic to penicillin.”
"I have terrible claustrophobia."
"I have an implanted pacemaker."
The Correct Answer is A
A. “I have just been started on metformin." Metformin use requires caution with contrast as it increases the risk of lactic acidosis, especially if renal function is impaired.
B. "I am allergic to penicillin": This allergy is unrelated to contrast agents.
C. "I have terrible claustrophobia": Claustrophobia can be managed with anxiolytics and would not necessarily delay the scan.
D. "I have an implanted pacemaker": Pacemakers are not a contraindication for CT scans.
