When reviewing a remote monitoring ECG, the QRS voltage is low, making it
difficult to review. What can be done to better view the QRS complex?
decrease gain.
increase the gain.
increase the paper speed.
nothing, no manipulation will improve tracing. - Correct Answer -increase the
gain.

calipers, 21g IV, IV pump, surgical mask
electrodes, treadmill, BP cuff, ECG machine
electrodes, defibrillator, surgical mask, disinfectant - Correct Answer -electrodes,
treadmill, BP cuff, ECG machine

block or complete heart block?
first degree AV block
second degree AV block, Mobitz type I
second degree AV block, Mobitz type II
second degree AV block, Mobitz type III - Correct Answer -second degree AV
block, Mobitz type II
Which of the following is a single early electrical impulse that originates in the
atrioventricular junctional tissue, occurring before the next expected sinus
impulse?
junctional tachycardia
junctional escape rhythm
supraventricular tachycardia (SVT)
premature junctional complex (PJC) - Correct Answer -premature junctional
complex (PJC)
Sagittal plane (medial) - Correct Answer -divides body into left and right
Coronal plane (frontal) - Correct Answer -divides body into front and back
,transverse plane (horizontal) - Correct Answer -horizontal division of the body
into upper and lower portions
Proximal - Correct Answer -Near the attachment of an extremity to the trunk or
a structure, closer to any point of reference such as origin of a structure or
center of body
Distal - Correct Answer -farther from the attachment of an extremity to the
trunk or a structure, farther from point of reference
Anterior - Correct Answer -near the front of the body (ventral)
Posterior - Correct Answer -Near the back of the body (dorsal)
supine - Correct Answer -lying o n the back with face upward or denoting the
position of the hand with the palm facing downward
prone - Correct Answer -lying horizontal with face downward, or denoting the
hand with palms turned upward
, Dark line method - Correct Answer -heart rate determination method that can
only be used when the heart rate is regular. This method can be a very accurate
way to determine heart rate or to generate a close estimate
1500 method - Correct Answer -Count number of small squares between two
consecutive R-waves and divide that number by 1500, it is the most accurate
method of obtaining the heart rate but can only be used on regular rhythms.
6 second method - Correct Answer -The number of QRS Complexes between 6
sec marks on the EKG paper is multiplied by 10. Used generally for estimating
slow or irregular rhythms.
atrioventricular valves - Correct Answer -Valves located between the atrial and
ventricular chambers on each side of the heart, prevent backflow into the atria
when the ventricles are contracting.
semilunar valves - Correct Answer -pulmonary and aortic valves located
between the right ventricle and the pulmonary artery and between the left
ventricle and the aorta
