EKG & Cardiovascular Testing — Free CCMA Practice Test

1) To improve skin–electrode contact and reduce artifact before a 12-lead EKG, the CCMA should:

2) Which limb lead color/location pairing is CORRECT for a standard EKG?

3) The correct position for V1 is:

4) The standard EKG paper speed used in most U.S. clinics is:

5) The standard gain (amplitude) setting is typically:

6) Uniform thick “fuzzy” tracing across the strip most likely indicates:

7) A treadmill stress test should be stopped immediately if the patient develops:

8) To reduce somatic tremor artifact in a patient with Parkinson disease during EKG, the CCMA should:

9) Which rhythm is a medical emergency requiring immediate defibrillation and EMS activation?

10) Using the 1,500 method, an R–R interval measuring 20 small boxes corresponds to a heart rate of:

11) On a 6-second strip (30 large boxes), you count 8 QRS complexes. The approximate heart rate is:

12) A normal adult PR interval is approximately:

13) A normal QRS duration is typically:

14) Which leads view the inferior wall of the heart?

15) Lead I measures the electrical potential between which limb electrodes?

16) The right leg (RL) electrode on a 12-lead EKG primarily serves as the:

17) For a patient with suspected dextrocardia, which modification is appropriate?

18) Holter monitor instructions should include:

19) A 30-day event monitor is best described as a device that:

20) If the RA and LA limb electrodes are reversed, which finding is most likely on the tracing?

21) Correct placement for V6 is at the:

22) At the start of the tracing, the calibration box measures 5 mm tall. This indicates the gain is set to:

23) If limb electrodes must be moved to the torso (e.g., tremor), the CCMA should also:

24) V3 is correctly placed:

25) Before transmitting or uploading a completed EKG, the MA should FIRST ensure that the tracing shows:
