When admitting a patient for a cardiac catheterization and coronary angiogram, which infor-mation about the patient is most important for the nurse to communicate to the health care pro-vider?
a. The patient's pedal pulses are +1.
b. The patient is allergic to shellfish.
c. The patient had a heart attack a year ago.
d. The patient has not eaten anything today.
ANS: B
The contrast dye used for the procedure is iodine based, so patients who have shellfish allergies will require treatment with medications such as corticosteroids and antihistamines before the an-giogram. The other information is also communicated to the health care provider but will not re-quire a change in the usual precardiac catheterization orders or medications.
