A patient with ST-segment elevation in three contiguous electrocardiographic (ECG) leads is admitted to the emergency department (ED) and diagnosed as having an ST-segment-elevation myocardial infarction (STEMI)
Which question should the nurse ask to determine whether the patient is a candidate for thrombolytic therapy?
a. "Do you have any allergies?"
b. "Do you take aspirin on a daily basis?"
c. "What time did your chest pain begin?"
d. "Can you rate your chest pain using a 0 to 10 scale?"
ANS: C
Thrombolytic therapy should be started within 6 hours of the onset of the myocardial infarction (MI), so the time at which the chest pain started is a major determinant of the appropriateness of this treatment. The other information will also be needed, but it will not be a factor in the decision about thrombolytic therapy.
