Which therapeutic intervention would the nurse question? a. Emergent pacemaker insertion
b. Emergent percutaneous coronary intervention
c. Emergent thrombolytic therapy
d. Immediate coronary artery bypass graft surgery
A
The goals of management of AMI are to dissolve the lesion that is occluding the coronary artery and to increase blood flow to the myocardium. Options include emergent percutaneous intervention, such as angioplasty, emergent coronary artery bypass graft surgery, or thrombolytic therapy if the patient has been symptomatic for less than 6 hours. No data in this scenario warrant insertion of a pacemaker.
