1) The pulseless ventricular tachycardia rhythm is primarily identified by several criteria: a) 180 beats per minute, and the rhythm generally has a very wide QRS complex,the patient will be pulselessthe rhythm originates in the ventricles. b) First, the rate is usually greater than 180 beats per minute, and the rhythm generally has a very wide QRS complex c) Second, the patient will be pulseless d) third, the rhythm originates in the ventricles. 2) Not all ventricular tachycardias are pulseless, and therefore, pulselessness must be established prior to beginning an algorithm. True or False a) False b) True 3) Pulses that should be checked when controlling a tachycardia: a) Radial or femoral pulse b) Carotid or radial pulse c) carotid or femoral pulse 4) why does a lack of pulse with tachyarrhythmia occur? a) Because the ventricles do not effectively draw blood from the heart and therefore there is no cardiac output. b) Pulseless ventricular tachycardia is treated using the left branch of the cardiac arrest algorithm. 5) Many tachyarrhythmias with a rate greater than........ deteriorate and stop pulsing if not treated in time. a) 120 b) 200 c) 160 d) 100 e) 150 f) 122 6) Monomorphic ventricular tachycardia and polymorphic ventricular tachycardia have the complex: a) short complex b) long complex c) no complex d) wide complex 7) Wide complex tachycardias are defined as a QRS of a) ≥ 0.10 second b) ≥ 0.11 second c) ≥ 0.13 second d) ≥ 0.23 second e) ≥ 0.12 second f) ≥ 0.14 second 8) what does the treatment of monomorphic VT depend on? a) depends on whether the patient is stable or unstable b) depends on whether the patient is stable c) depends on whether the patient is unstable 9) In polymorphic ventricular tachycardia, are the QRS waves symmetrical? True or False a) False b) True 10) treatment for unstable polymorphic ventricular tachycardia? a) oxygen b) defibrillation c) saline solution d) medication 11) Where do wide complex tachycardias originate? a) atria b) left ventricle c) ventricles d) right atria 12) 12. The primary cause of VF is: a) anoxia b) hypoxemia c) hypoxia 13) Treatment for ventricular fibrillation: a) oxygen b) saline solution c) medication d) defibrillation 14) The most common cardiac arrhythmia is: a) Atrial Flutter b) Supraventricular Tachycardia (SVT) c) atrial fibrillation d) Second-Degree (AV) Heart Block 15) What is the frequency of tachyarrhythmia? a) rate > 120 beats/min b) rate > 160 beats/min c) rate > 100 beats d) rate > 100 beats/min e) rate > 10 beats/min f) rate > 100 min 16) Common symptoms of tachyarrhythmia: a) normal breaths b) palpitations or chest discomfort c) hypertension d) brain edema 17) On an ECG monitor, there are two main features that will help you identify atrial fibrillation: a) No p-waves before the QRS - The heart rate will be irregular b) No p-waves before the QRS - The heart rate will be regular c) P-waves before the QRS - The heart rate will be irregular d) p-waves before QRS - Heart rhythm will be regular. 18) Are used drugs to manage unstable tachycardia? True or False a) True b) False 19) The appropriate voltage for cardioverting unstable atrial fibrillation is: a) 100-200 J. b) 120-210 J. c) 10-210 J d) 120-10 J. e) 120-210 f) 120-200 J. 20) First-degree heart block is also called as: a) first-degree VA block b) first-degree block c) second-degree AV block d) first-degree AV block
