NHA EKG Practice Test
ST segment elevation is associated with - correct answer 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 - correct answer notify the physician
if the QRS is too tall to fit on the ekg paper, change the gain control to - correct answer
1/2
if the patient is alert and orientated, but the tech finds all waveforms to be negative,
check the - correct answer left and right arm limb leads
decreased potassium levels cause what to be visible on an ekg? - correct answer u
waves
the classic presentation of ischemia include - correct answer 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? - correct answer the brachial artery
who should make repairs to the ekg machine? - correct answer a biomedical tech
if a physician orders a telemetry monitor to be worn at home, what statement would
show the need for further instruction? - correct answer "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 - correct answer torso
when preforming a posterior ekg, where should v8 be placed? - correct answer on the
left midscapular line
what controls the height of the waveform on an ekg? - correct answer sensitivity
peaked, hypacute, and broad based T waves and convex ST segments are classic
findings of? - correct answer myocardial ischemia
what can be used up to two hours prior to a stress test because of its short half-life? -
correct answer tobacco products
where should v5 be placed? - correct answer v5 should be placed on the left anterior
axillary line, horizontal to v4
