NHA EKG PRACTICE TEST NEW EXAM AHEAD QUESTIONS AND ANSWERS PRACTICE
SOLUTION
ST segment elevation is associated with - myocardial injury
during a stress test the patient begins to feel fatigue and the ekg shows v-tach the first thing you
should do is - notify the physician
if the QRS is too tall to fit on the ekg paper, change the gain control to - 1/2
if the patient is alert and orientated, but the tech finds all waveforms to be negative, check the -
left and right arm limb leads
decreased potassium levels cause what to be visible on an ekg? - u waves
the classic presentation of ischemia include - ST segment depression and T wave inversion
what is the easiest site to obtain a pulse on an infant because of its proximity to the surface of
the skin? - the brachial artery
who should make repairs to the ekg machine? - a biomedical tech
if a physician orders a telemetry monitor to be worn at home, what statement would show the
need for further instruction? - "if a lead comes loose, i may reattach it myself"
when preforming an ekg on a two-year old patient you should move the limb leads to the - torso
when preforming a posterior ekg, where should v8 be placed? - on the left midscapular line
what controls the height of the waveform on an ekg? - sensitivity
peaked, hypacute, and broad based T waves and convex ST segments are classic findings of? -
myocardial ischemia
