An emergency department nurse has transferred a patient to the radiology department for a CAT scan with contrast. The nurse hears a code called in the radiology room where her patient is having their CAT scan
A) A myocardial infarction
B) A cerebrovascular accident
C) An anaphylactic reaction
D) A pulmonary emobolism
Ans: C
Feedback: Many medications have been implicated in anaphylaxis. Those that are most frequently reported include antibiotics, radiocontrast agents, intravenous anesthetics, aspirin, other nonsteroidal anti-inflammatory drugs, and opioids. A myocardial infarction, cerebrovascular accident, or pulmonary embolism are all possibilities for impending death. However, antibiotics and radiocontrast agents cause the most serious anaphylactic reactions, producing reactions in about 1 of every 5000 exposures. There would be no reason for the ED nurse to suspect an MI, CVA, or PE.
