A nurse assesses a client's electrocardiogram (ECG) and observes the reading shown below:
 
  How should the nurse document this client's ECG strip?
  a.
  Ventricular tachycardia
  b.
  Ventricular fibrillation
  c.
  Sinus rhythm with premature atrial contractions (PACs)
  d.
  Sinus rhythm with premature ventricular contractions (PVCs)

Question 2

A nurse supervises an unlicensed assistive personnel (UAP) applying electrocardiographi c monitoring. Which statement should the nurse provide to the UAP related to this procedure?
 
  a. Clean the skin and clip hairs if needed.
  b. Add gel to the electrodes prior to applying them.
  c. Place the electrodes on the posterior chest.
  d. Turn off oxygen prior to monitoring the client.

Answer to Question 1

ANS: D
Sinus rhythm with PVCs has an underlying regular sinus rhythm with ventricular depolarization that sometimes precede atrial depolarization. Ventricular tachycardia and ventricular fibrillation rhythms would not have sinus beats present. Premature atrial contractions are atrial contractions initiated from another region of the atria before the sinus node initiates atrial depolarization.

Answer to Question 2

ANS: A
To ensure the best signal transmission, the skin should be clean and hairs clipped. Electrodes should be placed on the anterior chest, and no additional gel is needed. Oxygen has no impact on electrocardiographi c monitoring.
