Module 1. Nursing Care of Patients with
Cardiac Dysrhythmias
Several different recordings can be obtained by using a variety of electrode
combinations called __________. - answerLeads
Correctly identify lead placement and color on the chest wall to obtain a 5-lead EKG.
Select all that apply - answerLL - Left leg - Red
RA - Right Arm - White
RL - Right Leg - Green
The key to the elimination of artifact is using which of the following? - answerProper skin
preparation
Which of the following is an abnormal ECG pattern caused by muscular activity, patient
movement, electrical interference, or lead cable or electrode malfunction? -
answerArtifact
Inoperative (inop) monitoring alarms are used to communicate which of the following
issues? - answerLeads are loose
Electrodes have fallen off
Bterm-5attery power is low
The ________________ stress test procedures are noninvasive ways to evaluate the
response of the cardiovascular system to stress. - answerCardiac
_________ agents, such as dipyridamole (Persantine), adenosine (Adenocard), or
regadenoson (Lexiscan), given as an IV infusion are used to mimic the effects of
exercise by maximally dilating normal coronary arteries. - answerVasodilating
Locating which of the following is critical for the correct placement of each chest
electrode? - answerSpecific intercostal space
P wave - answerRepresents the electrical impulse starting in the SA node and
spreading through the atria
QRS complex - answerRepresents ventricular depolarization
T wave - answerRepresents ventricular repolarization (when the cells regain a negative
charge; also called the resting state)
