1. What does the P wave on a rhythm strip represent?: electrical stimulation of
both atriums of the heart
2. What does the T wave represent on an electrocardiogram or rhythm strip?-
: Repolarization of the ventricles of the heart
3. A client with a prolonged QT interval is at highest risk for which life-threat-
ening cardiac rhythm?: Ventricular fibrillation
4. Order the parts of the cardiac conduction system from where an electrical
impulse normally starts to where it ends.: SA node
Atria
AV node
Bundles of HIS
Ventricles
5. In the QRS complex shown here, the PR interval is ____________ ms,
the QRS interval is ____________ ms and the QT interval is ____________
ms: 0.16, 0.08, 0.40
6. Identify the correct intervals for this cardiac cycle from the choices given.: 1.
PR interval
2. QT interval
3. QRS interval
7. Which clients are at risk for cardiac dysrhythmia? Select all that apply.: A
young adult who consumes multiple energy drinks per day
An adult living with cardiomyopathy
A teen whose serum potassium is high
A child being resuscitated from drowning
8. How should the nurse document the client's cardiac rhythm?: Pulseless
electrical activity
9. Place the steps for interpreting an electrocardiogram (ECG) strip in the
correct order, from first to last.: Identify and examine the P wave
Measure the PR interval
Measure the QRS complex
Identify the rhythm as regular or irregular
