A patient complained of Epigastric pain has ST elevation in ECG leads
II, III, and aVF. She is diagnosed with an inferior MI, and NTG is
administered sublingually. Her blood pressure drops from 120/47 to
90/60 so the Provider order is a right-sided ECG while awaiting
cardiology. Where is the correct leap placement for V4R to detect right
ventricular MI's?
a. 2nd ICS R sternal border
b. 4th ICS R mid-cliviclar line
c. 5th ICS L mid-clavicular line
d. 5th ICS R mid-axillary line - Precise Answer ✔✔b. 4th ICS R mid-
cliviclar line
Which of the following conditions is commonly associated with
bradycardias and second agree, type I heart block?
a. Cardiogenic shock
b. occlusion of the right coronary artery
c. occlusion of the left anterior descending artery
d. prinzmeta's angina - Precise Answer ✔✔b. occlusion of the right
coronary artery

A patient with Ehlers Danlos complains of a sudden onset of severe
chest to scapular pain. Heart rate 98 BPM. The left brachial BP is
180/90, the right brachial BP is 150/70. What is the priority intervention
