QUESTIONS WITH VERIFIED
SOLUTIONS CURRENTLY TESTETD
AND APPROVED
What interval measurement represents the complete refractory period?
P wave to T wave
P wave to ST segment
QRS wave to next P wave
QRS to peak of the T wave -- ANSWER--QRS to peak of the T wave
What is the first step in preparation of the patient for ECG monitoring?
Do not prepare patient skin before applying leads
Reassure patient and maintain privacy
Turn on the monitor so the alarm sounds
Undress the patient and apply leads -- ANSWER--Reassure patient and maintain privacy
Which of the following is an important electrolyte that affects cardiac function?
, Page 2 of 65
Chloride
Glucose
Phosphorus
Potassium -- ANSWER--Potassium
When the parasympathetic nerve fibers are stimulated, what is released?
Acetylcholine
Adrenaline
Norepinephrine
Vagal -- ANSWER--Acetylcholine
The ECG produces an upright pattern on the paper in response to what?
Electricity flowing away from a negative electrode
Electricity flowing diagnonal
Electricity flowing from the heart towards a positive electrode
Non-electricity flowing backwards -- ANSWER--Electricity flowing from the heart towards a
positive electrode
Sinus pause includes what two things? -- ANSWER--Sinus arrest and sinoatrial exit block
Sinus pause is one or two missed beats
, Page 3 of 65
Sinus arrest? -- ANSWER--Failure of the SA node to create an impulse, an interruption of RR
regularity
When 3 or more beats aren't formed
Sinoatrial exit block? -- ANSWER--SA node generates impulse but is blocked before being
transmitted through the atria (missed or dropped beats)
R-R regularity continues with beats that follow the missed beat
Which valves are classified as the atrioventricular valves?
Mitral and pulmonic
Mitral and tricuspid
Pulmonic and aortic
Tricuspid and aortic -- ANSWER--Mitral and tricuspid
What allows the cardiac cells to transmit an electrical impulse?
Automaticity
Conductivity
Contractility
Excitability -- ANSWER--Conductivity
Along with Lead II, what is Lead III most helpful for monitoring?
, Page 4 of 65
Anterior wall
Changes associated with inferior wall myocardial infarction
QRS complexes
Ventricular function -- ANSWER--Changes associated with inferior wall myocardial
infarction
What electrolyte is important in cardiac muscle contraction?
Calcium
Chloride
Glucose
Phosphorus -- ANSWER--Calcium
What is the normal measurement for the QRS complex?
0.04 to 0.12 seconds
0.04 to 0.10 seconds
0.10 to 0.24 seconds
0.14 to 0.20 seconds -- ANSWER--0.04 to 0.10 seconds
