Term
REASONS FOR PERFORMING AN ECG ARE:
 Definition
to check for problems with the flow of electricity through the heart, to diagnose changes in the heart rhythm, to check for abnormalities before surgery, to assist in evaluating a person's health after age 40 during a complete physical exam, to monitor or evaluate heart conditions, to evaluate the effectiveness of medications on the heart.
Term
YOU ARE TALKING WITH A CO-WORKER IN THE RECEPTION AREA ABOUT HOW DR. HEART REALLY "DOESN'T KNOW" ALOT ABOUT TREATMENT FOR HEART DISEASE EVEN THOUGH HE TREATS PATIENTS WITH HEART DISEASE. THIS IS CONSIDERED TO BE:
 Definition
slander
Term
ECG TRACINGS CAN BE PERFORMED FOR A VARIETY OF REASONS AND ON DIFFERENT TYPES OF EQUIPMENT. IN WHAT TYPE OF AREA MAY ECG'S BE PERFORMED.
 Definition
In the hospital, in the doctors office and ambulatory care facilities outside a health care facility.
Term
A PATIENT STATES "I DON'T WANT TO BE SHOCKED WITH THE ELECTRICITY" WHILE YOU ARE SETTING UP A HOLTER MONITOR. YOUR BEST RESPONSE IS:
 Definition
In a calm manner, explaine that the machine does not produce or generate electricity and it is not harmful.
Term
THE ELECTROCARDIOGRAM IS A STUDY OF:
 Definition
electrical activity within the heart.
Term
TELEMETRY MONITORING IS WHAT KIND OF USAGE FOR ECG.
 Definition
continuous
Term
LEAVING THE PATIENT'S CHART IN A FULL WAITING ROOM WHILE YOU HELP SOMEONE TO THE EXAM ROOM COULD BE CONSIDERED:
 Definition
a breach of confidentiality
Term
THE VALVES LOCATED IN THE HEART ARE IMPORTANT BECAUSE:
 Definition
they prevent backflow of blood from the ventricles to the atria and prevents the backflow of blood into the ventricles.
Term
THE NORMAL QRS DURATION IS:
 Definition
0.06 to 0.10 seconds
Term
THE "LUBB" AND "DUPP" SOUNDS YOU HEAR ARE MADE BY:
 Definition
the opening and closing of the heart valves.
Term
THE QRS COMPLEX REPRESENTS:
 Definition
ventricular depolarizations or ventricular contractions (mean the same)
Term
BLOOD RETURNS TO THE HEART VIA VEINS. THE LARGEST VEIN IS THE:
 Definition
vena cava
Term
THE FUNCTION OF THE BUNDLE BRANCH SYSTEM IS TO:
 Definition
conduct impulses down both sides of the interventricular septum.
Term
THE PR INTERVAL REPRESENTS THE TIME IT TAKES THE ELECTRICAL CURRENT TO TRAVEL:
 Definition
from the SA node to the AV node (to ventricals prior to contraction)
Term
THE SA NODE WILL SEND AN ELECTRICAL IMPULSE AT A RATE OF:
 Definition
60 to 100 times per minute.
Term
THE AV NODE HAS SEVERAL IMPORTANT QUALITIES THAT HELP THE HEART FUNCTION EFFECTIVELY. ALL OF THESE ARE QUALITIES OF THE AV NODE:
 Definition
conductivity through a specialized pathway through the atria, causes a delay in the electrical impulse, increases the cardiac output or the amount of blood that is pumped out of the heart into the body with each contraction, reduces the number of electrical impulses transmitted to the ventricles, can act as the pacemaker.
Term
DEPOLARIZATION OF THE CELLS CAUSES THE HEART MUSCLE TO:
 Definition
contract and pump blood to the body.
Term
THE SIGNAL PROCESSING OCCURS INSIDE THE ECG MACHINE AND IT:
 Definition
amplifies and prepares signal for transfer to the display and prints out
Term
IF CURRENT MOVES AWAY FROM THE POSITIVE ELECTRODE ON AN ECG, THE ECG WAVEFORM WILL HAVE A_________DEFLECTION.
 Definition
negative or downward
Term
UNIPOLAR LEADS INCLUDE ALL THE LEAD TYPES EXCEPT:
 Definition
standard (= LEAD 1, LEAD2, LEAD 3/LIMB LEADS)
Term
IN ORDER TO BE ABLE TO INTERPRET THE INFORMATION, THE ECG MACHINE WILL _______ THE RECORDING IN AUGMENTED LEADS.
 Definition
increase  (augmented leads= aVR, aVL, aVF)
Term
THE 12-LEAD MACHINE WILL RECORD A STRIP 3 TO 6 FEET LONG SHOWING ALL 12 LEADS INDIVIDUALLY. THIS TYPE OF ECG MACHINE IS KNOWN AS:
 Definition
single channel.
Term
OFTEN IT IS DIFFICULT TO READ THE ECG TRACING WHEN THE RATE IS FAST. WHERE SHOULD YOU SET THE SPEED CONTROL RATE TO BE ABLE TO INTERPRET THE ECG TRACING MORE EASILY.
 Definition
50mm
Term
TO OBTAIN A 12-LEAD ECG TRACING, YOU MUST APPLY HOW MANY ELECTRODES TO THE PATIENT.
 Definition
10
Term
WHAT IS THE MOST COMMONLY USED STANDARD SPEED RATE FOR ECG MACHINES.
 Definition
25mm
Term
THE ECG GRAPH PAPER CONSISTS OF TIME HORIZONTALLY AND VOLTAGE VERTICALLY. WHAT IS THE TIME AND VOLTAGE REPRESENTED WITH 1 LARGE BOX.
 Definition
.5 seconds up and .20 seconds across
Term
AS YOU ARE CONDUCTING A 12-LEAD ECG, A RED LINE APPEARS AT THE BOTTOM OF YOUR ECG GRAPH PAPER. WHAT DOES THIS MEAN
 Definition
running out of paper.
Term
EACH LITTLE BOX ON THE ECG PAPER HORIZONTALLY REPRESENTS:
 Definition
0.04 seconds
Term
THE ECG WAVEFORM IS INDICATIVE OF:
 Definition
electrical impulses through the heart.
Term
IDENTIFY THE METHODS TO CALCULATE HEART RATE
 Definition
6 seconds or look at R-wave (RR)
Term
ELECTRICAL SAFETY IS MAINTAINED WHILE PERFORMING AN ECG BY ALL OF THE FOLLOWING EXCEPT:
 Definition
pacemaker
Term
YOU ARE ASKED TO PERFORM A V3R LEAD ON AN ADULT PATIENT. THIS LEAD IS LOCATED:
 Definition
on the right side of the sternum.
Term
WHILE WORKING IN A HOSPITAL OR ACUTE CARE FACILITY, YOU ARE RECORDING AN ECG ON A PATIENT AS ORDERED BY THE PHYSICIAN. HOW MANY COPIES DO YOU NEED TO MAKE.
 Definition
2
Term
A SINGLE-CHANNEL ECG MACHINE WAS USED TO RECORD A 12-LEAD ECG ON MR. SMITH, AND NOW YOU NEED TO MOUNT THE ECG TRACING. WHAT STEPS MUST YOU TAKE.
 Definition
mark each tracing with code, mount, record patient information.
Term
YOU NOTICE THAT ON LEADS I AND III THERE IS ALTERNATING CURRENT INTERFERENCE ON THE ECG TRACING. EVALUATING THE STRIP, OU DETERMINE WHICH ELECTRODE LEAD IS THE POTENTIAL SOURCE OF INTERFERENCE OR DIRECTION. IT IS THE:
 Definition
left arm.
Term
AFTER COMPLETION OF THE ECG PROCEDURE, WHAT ARE THE ECG TECHNICIAN'S RESPONSIBILITIES.
 Definition
clean the lead wires, wrap cords properly, assist patient bach to comfortable position.
Term
THE FOLLOWING CHEST LEADS ARE PLACED ON THE CHEST WITH DEFINITE LOCATIONS SPECIFIED:
 Definition
v1, v2, v4, v5, v6
Term
BEFORE OPERATING THE ECG MACHINE, MAKE SURE THAT YOU HAVE DONE ALL OF THE FOLLOWING:
 Definition
all leads in the right areas, check patient's ID, explaine procedure, use proper safety and infectios control.
Term
YOU ARE RECORDING AN ECG TRACING ON A FEMALE PATIENT WHO HAS HAD A MASTECTOMY. YOUR RESPONSIBILITIES INCLUDE:
 Definition
to document it.
Term
SINUS BRADYCARDIA (SB) HAS THE SAME CRITERIA AS SINUS RHYTHM WITH THE ONLY DIFFERENCE BEING THAT THE:
 Definition
heart rate is low.
Term
THE NORMAL RANGE OF THE PR INTERVAL IS:
 Definition
12-20
Term
ALL OF THE FOLLOWING RHYTHMS USUALLY FIND THE PATIENT IN SITUATIONS REQUIRING IMMEDIATE EMERGENCY INTERVENTIONS EXCEPT:

Term
YOUR RESPONSIBILITIES TO CARE FOR A PATIENT WITH COMPLETE HEART BLOCK:
 Definition
observe low cardiac output and report it, initiate emergency response if needed.
Term

 Definition
how wide is the QRS complex.
Term
QRS DURATION MEASUREMENT IS ESSENTIAL TO DETERMINE THE TIME IT TAKES FOR:
 Definition

 Definition
1500 or R-R
Term
DISCUSSING CONFIDENTIAL INFORMATION IN THE CAFETERIA REGARDING A PATIENT IS NOT CONSIDERED A LEGAL OR ETHICAL PROBLEM.
 Definition
false.
Term
AN INACCURATE 12-LEAD ECG TRACING DOESN'T INFLUENCE THE PATIENT'S CARE OR TREATMENT.
