(NEWEST 2026-2027) CCІ CRAT EXAM COMPLETE QUESTIONS
AND CORRECT ANSWERS
Which of the following pacemaker complications involves irregular pacemaker
intervals with slower than set rate impulses and no visual pacemaker spike?
Malfunctioning
-Malfunctioning is a complication in which the pacemaker does not send
electrical impulse to the myocardium. In this complication pacemaker intervals
are irregular, and the impulse is slower than the set rate. There is no pacemaker
spike seen.
Potassium and which of the following are needed in order for the heart to
function normally?
Calcium
-There are 3 electrolytes which the heart needs to function properly:
*Potassium
*Calcium
*Sodium
-If one of these three are lacking, the heart doesn't function well.
Saying words correctly would be considered and speaking clearly
would be considered ?
Pronunciation/enunciation
-When educating, the teacher needs to pay attention to both pronunciation and
enunciation.
-Saying words correctly would be considered pronunciation.
-Speaking clearly would be considered enunciation.
Premature atrial contractions are rarely dangerous but in a patient with which of
the following conditions, they can serve as an early sign of heart failure or
electrolyte imbalance?
,Acute myocardial infarction
-Patients with an acute myocardial infarction, premature atrial contractions can
serve as an early sign of heart failure or an electrolyte imbalance. Premature
atrial contractions in patient's with heart disease can lead to serious arrhythmias
such as atrial flutter and atrial fibrillation.
Which of the following does the CDC recommend that healthcare workers not
have?
Artificial nails
-The CDC recommends that healthcare providers not have artificial nails as they
are more apt to harbor gram-negative pathogens than natural nails, both before
and after proper hand washing techniques. The CDC recommends that natural
nails be no longer than 1/4 inch long as they can harbor pathogens at longer
lengths.
As an electrical current travels toward the negative pole on an ECG, the
waveform deflects which direction?
Downward
-As an electrical current travel toward the negative pole, the waveform deflects
in a downward direction. When the current flows perpendicular to the lead, the
waveform can be small or biphasic. As the current travels toward the positive
pole, the waveform deflects in an upward direction.
Which of the following is represented by the S wave?
Late ventricular depolarization
-Late ventricular depolarization is represented by the S wave.
-This is the last wave form in the QRS complex.
Which of the following would be considered correct for the reason that the left
side of the heart is thicker than the right?
It pumps the blood back to all of the parts of the body
-It pumps the blood back to all of the parts of the body. Because of the force
required by the heart to force the blood back to all of the parts of the body, the
left side of the heart will be thicker.
Which of the following starts at the beginning of the P wave and stops at the
beginning of the QRS complex?
,
