CCT CCI LATEST UPDATED 2025/2026 EXAM AND PRACTICE QUESTIONS EXAM NEWEST ACTUAL EXAM COMPLETE 500+ QUESTIONS WITH DETAILED VERIFIED ANSWERS (100% CORRECT ANSWERS) GRADED AT A+ On a cardiac rhythm strip, which of the following can determine if the patients heart rate is regular? The RR intervals being equal. The PP intervals being equal. The RR intervals being unequal. Both A and B - ANSWER If the RR or PP intervals are not equal, then the rhythm is irregular. One of the most uncommon rhythms that is always unequal is atrial fibrillation. 2. Of the following rhythms, which would not be considered a lifethreatening arrhythmia? Ventricular fibrillation Sinus rhythm with a 1st degree block Asystole Ventricular tachycardia - ANSWER Some of the life-threatening rhythms might include: Ventricular fibrillation Asystole Ventricular tachycardia Complete heart block 3. When checking the patient's orders prior to performing the ECG, the technician sees that the patient's temperature is to be taken axillary. Which of the following routes would be considered correct for axillary? Ear Mouth Armpit Anally - ANSWER The ear would be considered tympanic. The mouth would be considered orally. The anus would be considered rectally. The armpit would be considered axillary. 4. If the physician orders a treatment for a patient that is supposed to help prevent something from occurring, it would be considered which of the following Prophylaxis Chronic treatment Acute treatment None of the above - ANSWER Chronic treatment would be over a length of time. Acute treatment would be for sudden diagnosis. Prophylaxis would be treatment that would attempt to prevent something from occurring. 5. With a 12-lead electrocardiogram (ECG), which of the following would be the negative electrode position for lead II? Right arm Left arm Right leg Left leg - ANSWER The right arm would be the negative electrode position for lead II. The left leg in lead II would be a positive electrode position. The right leg is not included in the lead I, II or III electrode positions. 6. If the sinus nodes fails to regulate the heart rhythm, it is considered which of the following? Septal defect Idiopathic SSS Shunt - ANSWER Septal defect is a hole in the heart wall that separates the atria or the ventricles. Idiopathic is no known cause. Shunt is something that allows blood to flow between two locations. SSS is sick sinus syndrome or when the sinus node fails (is sick) and cannot regulate the hearts rhythm. 7. The positive electrode in lead II is placed in which position on the patient? Right chest area Left chest area Left leg None of the above - ANSWER Right and left chest area would not be correct. The left leg electrode is positive in Lead II. 8. The heart is made up of approximately how many cells? 200 hundred One trillion Half a billion 10 thousand - ANSWER Approximately half a billion cells make up a standard human heart. Most of them make up the ventricular walls. There are approximately 100 million myocardial cells that contract every one third of a second. 9. If a patient is on continuous cardiac monitoring, which of the following leads would most likely be seen on the monitor? Lead III Lead I Lead II All of the above - ANSWER The typical lead that is displayed on a cardiac monitor is lead II. Most cardiac monitor have the ability of changing this to a different lead, but this has to be done by the healthcare staff. 10. Unresolved atrial fibrillation or atrial flutter is typically treated with which of the following? Lipitor Coreg Procardia Coumadin - ANSWER If atrial fibrillation or atrial flutter is unresolved, it has the potential to developing blood clots. These patient's are typically placed on an anticoagulant medication such as Coumadin. 11. The nurse is caring for a patient that has had a myocardial infarction and is experiencing chest pain. Which of the following would be considered the typical medication used for the relief of chest pain? Coreg Tylenol Lidocaine Morphine - ANSWER Coreg, tylenol, and lidocaine is not used for myocardial infarction chest pain. The drug of choice for most chest pain is considered morphine. It is administered by IV per the dosage ordered by the physician. The typical dose would be considered 2-5 mg and may repeat every 5 minutes up to 10 mg. 12. When the ECG technician is applying the electrodes for a stress test, they place the V1-V6 leads and then which of the following? RA/LA aVL/aVF RL/LL Both A and C - ANSWER With the stress test, there are 10 leads. These leads include: V1-V6 RA/LA RL/LL 13. The mean instantaneous vector would be considered which of the following? Bipolar lead Unipolar lead Electrical axis Focal point - ANSWER The mean instantaneous vector would be considered the electrical axis. The electrical axis of the heart would be considered the direction of the electromotive force that is developed in the heart during activation. 14. Which of the following leads would help to record the electrical activity in the heart's horizontal plane? Bipolar lead 12-lead ECG Precordial leads Unipolar leads - ANSWER The precordial leads help to record the electrical activity of the heart's horizontal plane of the heart. This provides a transverse view through the middle of the heart which divides it into upper and lower portions. 15. Of the electrocardiogram waves, which would be considered the first deflection after the diastole that is produced because of the atrial depolarization? T wave S wave Q wave P wave - ANSWER Of the P, Q, R, S, and T waves, the wave that would be considered the deflection after the diastole would be the P wave. This occurs because of the atrial depolarization of the heart. 16. The Bundle of His has an intrinsic firing rate of which of the following? 40 to 60 beats per minute 30 to 60 beats per minute 60 to 80 beats per minute 80 to 100 beats per minute - ANSWER The Bundle of His is located at the superior portion of the interventricular septum. The Bundle of His is actually the pathway of the electrical impulses that lead out of the SA node. They have the ability to initiate their own electrical impulses at a rate of 40 to 60 beats per minute. 17. If a patient is experiencing a low blood pressure, which of the following terms would be correct? Hypertension Hypoxemia Hypotension Hypoplastic - ANSWER Hypertension would be high blood pressure. Hypoxemia would be a low oxygen concentration in the blood. Hypoplastic would be when an organ is abnormally small because of a problem with development prior to birth. Hypotension is low blood pressure. 18. The aVR lead picks up electrical activity from which of the following? The center of the heart to the right arm. The center of the heart to the left leg. The center of the heart to the left arm. From the left arm to the left leg. - ANSWER The center of the heart to the left leg would be the aVF. The center of the heart to the left arm would be the aVL. The center of the heart to the right arm would be the aVR. From the left arm to the left leg would be lead III.
