M5 EKG Quiz – 4.5 out of 5
1. On a 12 lead ECG, the P waves represents:
Atrial depolarization
2. T wave inversion eight hours after a myocardial infarction may
indicate:
Ischemia
3. Left ventricular hypertrophy is is diagnosed by measuring R waves in
leads:
V5 and V6
4. The ECG tech seems to be in a big rush to get the patient's ECG
completed. What common placement error can cause the wave
pattern to look like the patient is having a myocardial infarction when
they are not?
(incorrect) V1 and V2 are not placed in the 4th
intercostal space correctly.
5. The NP notes tall peaked T waves when reviewing a patient's ECG.
The most likely cause of this phenomenon is:
Hyperkalemia
6. To differentiate between left bundle branch block and anterior wall
infarction, the NP considers:
QRS duration and T wave inversion
