CCI CRAT Exam Practice Test 3 QUESTIONS WITH CORRECT ANSWERS

Of the following, which would not be indicative of ventricular fibrillation? - ANS Waves would be seen with every other complex The following would be indicative of ventricular fibrillation: No waves will be seen The QRS will be more than 120ms The rate will be 100-250 The patient will lose consciousness If a premature ventricular contraction (PVC) comes from different foci, they are referred to as which of the following? - ANS Multifocal PVC's If the PVC's come from different foci, they would be referred to as multifocal PVC's.If the PVC's come from a common point or focus and appear the same shape, they would be considered unifocal PVC's. Report a problem with this question If they suspect the patient has premature ventricular contraction, which of the following would the nurse look for on the ECG strip? - ANS Irregular rhythm and premature QRS complexes that are wide and uncommon If they suspect the patient has premature ventricular contraction the nurse would look for an irregular rhythm and premature QRS complexes that are wide and uncommon on the ECG strip. This condition can also cause a loss of atrial kick and reduce ventricular filling time causing a problem with cardiac output. Which of the following would be considered the approximate O2 saturation of the blood in the right atrium? - ANS 60-75% The approximate O2 saturation of the blood in the right atrium would be 60-75%. This is deoxygenated blood that returns to the heart from the body. It will have a high concentration of C02. Deoxygenated blood returns to the heart through the inferior and superior vena cava and empties into which of the following? - ANS Right atrium Deoxygenated blood returns to the heart through the inferior and superior vena cava and empties into the right atrium. From the right atrium, the blood goes through the tricuspid valve into the right ventricle. The stretching of muscle fibers in the ventricles is known as which of the following? - ANS Preload Preload is the stretching of muscle fibers in the ventricles and is ascertained by the pressure and amount of blood unexpended in the left ventricle at the end of diastole. Afterload is the amount of pressure the left ventricle must push against to pump blood into the circulation. When the patient has no electrical activity in the heart and is unresponsive with no cardiac output, the cardiac monitor would show which of the following? - ANS Asystole When the patient has no electrical activity in the heart and is unresponsive with no cardiac output, it is called asystole. This condition normally results from a prolonged period of cardiac arrest where there was not effective resuscitation. Patients with idioventricular rhythms require which of the following? - ANS Continuous ECG monitoring Patients with idioventricular rhythms require continuous ECG monitoring and constant assessment until their treatment restores hemodynamic stability. The patient should be on bed rest with pacemaker equipment at the bedside with atropine readily available. Patient demographic sheets include all of the following information except? - ANS Patient religious preference
