EKG New grad exam questions and
answers10
Normal PR interval length - ANSWERS-0.12-0.20 seconds
QRS normal width - ANSWERS-0.06-0.11
What do peaked T waves indicate? - ANSWERS-High potassium
QT interval normal length - ANSWERS-0.36-0.44
EKG paper one small box - ANSWERS-0.04 seconds
EKG paper one big box - ANSWERS-0.20 seconds
Measuring rate 6 second method - ANSWERS-Count number of R waves and multiply by 10
Measuring rate by division - ANSWERS-Count large boxes between 2 R waves and divide by the
number of large boxes. Ex: 300/3.4
What causes artifacts on an EKG? (3) - ANSWERS-1. Loose electrode that is not in contact with
the skin
2. A broken cable
3. Shivering or movement
, Sinus brady treatment - ANSWERS-underlying causes
transcutaneous pacing
atropine and epi while waiting for pacing
Sinus tachycardia treatment - ANSWERS-underlying cause
beta blocker or calcium channel blocker
Supraventricular tachycardia clinical consequences - ANSWERS-decreases ventricular stroke
volume
Stable SVT treatment - ANSWERS-Adenosine (drug of choice), beta blocker, calcium channel
blocker
Unstable SVT - ANSWERS-Synchronized cardioversion
clinical consequences of atrial flutter and atrial kick - ANSWERS-loss of atrial kick
