DAANCE EXAM (QUESTIONS AND ANSWERS) 2023/2024 Wave of Depolarization - CORRECT ANSWER-an advancing wave of charge reversal as the nerve impulse advance a long the neuron Wakefullness system - CORRECT ANSWER-consists of a central core in the brainstem with neurons that radiate to the cortex Vomiting Center - CORRECT ANSWER-the center in the brainstem that induces vomiting Vital Centers - CORRECT ANSWER-centers in the brainstem that control such physiologic processes as blood pressure and pulse, depth and rate of respiration Vestibular nerve - CORRECT ANSWER-part of the eighth cranial nerve that is connect with equilibrium and hearing Venule - CORRECT ANSWER-any of the small vessels that collect blood from networks of capillaries and join them to form veins Ventricular tachycardia - CORRECT ANSWER-a cardia dsrhythmia in which there is rapid firing of an ectopic focus in the ventricles and a wide QRS complex with no p waves Ventricular rhythms - CORRECT ANSWER-a cardia dsrhythmia in which the pacemaker is in the ventricles rather than in the SA node or atria Ventricular focus - CORRECT ANSWER-a displace point of origin for a dysrhythmia that is in the ventricles Ventricular fibrillation - CORRECT ANSWER-arrhythmia characterized by contractions of ventricle muscle fibers due to rapid excitation of myocardial fibers without coordinated contraction of the ventricle Sensory nerve - CORRECT ANSWER-a nerve of the peripheral nervous system that conducts impulses from a sense organ to the spinal cord or brain Sinoatrial node - CORRECT ANSWER-a microscopic collection of heart muscle fibers where cardiac rhythm originates; also called the pacemaker of the heart sinus arrhythmia - CORRECT ANSWER-a cardiac dysrhythmia similar to normal sinus rhythm, but withslight variation in rate with inspiration and expiration sinus bradycardia - CORRECT ANSWER-cardiac dysrhythmia similar to normal sinus rhythm except for a slower rate of less than 60 bpm sinus rhythms - CORRECT ANSWER-cardiac rhythms in which the pacemaker is the sinoatrial node sinus tachycardia - CORRECT ANSWER-dysrhythmia similar to normal sinus rhythm except for an increase in rate of greater than 100 bpm but less than 150 bpm stroke volume - CORRECT ANSWER-the amount of blood ejected from a ventricle during each beat of the heart subcutaneous - CORRECT ANSWER-beneath the skin superior vena cava - CORRECT ANSWER-the venous trunk that drains blood from the head, neck, upper extremities, and chest and empties into the right atrium of the heart supraventricular foci - CORRECT ANSWER-central points of origin of dsrhythmias, which are located above the level of the ventricles in the atria sympathommimetic - CORRECT ANSWER-having activity that mimics the effects of the sympathetic nervous system, epinephrine synapse - CORRECT ANSWER-the junction between two neurons where impulses are transmitted from one neuron to another synaptic cleft - CORRECT ANSWER-the gap between two nerves where they meet at a synapse syncope - CORRECT ANSWER-fainting synergistic - CORRECT ANSWER-the phenomenon that exists when two drugs are administered together, and the combined effect is greater than the sum of its parts systolic - CORRECT ANSWER-pertaining to the phase of the heart's pumping action when the ventricles contract, forcing blood either to the lungs or peripheral circulation T wave - CORRECT ANSWER-the EKG waveform that represents repolarization of the ventricles Tachycardia - CORRECT ANSWER-fast heart rate terminal button - CORRECT ANSWER-the bulge at the end of the nerve that touches the next nerve in the never pathway at a synapse third degree AV block - CORRECT ANSWER-an atrioventricular block in which the impulse does not conduct from the atria to the ventricles and there is independent contraction of the atria and ventricles Thrombosis - CORRECT ANSWER-formation of a blood clot in a blood vessel, usually a vein Tidal Volume - CORRECT ANSWER-the amount of gas that is inspired or expired during one respiratory cycle titrate - CORRECT ANSWER-to give a small quantity of a drug and assess its effects before giving additional drugs trachea - CORRECT ANSWER-windpipe tracheostomy - CORRECT ANSWER-the surgical creation of an opening into the trachea through the neck transient ischemic attack - CORRECT ANSWER-a brief attack of cerebral dysfunction caused by reduced blood flow in the brain trigeminal nerve - CORRECT ANSWER-the fifth cranial nerve, which supplies sensation to the face, teeth, mouth, and nasal cavity type I diabetes - CORRECT ANSWER-insulin-dependent diabetes type II diabetes - CORRECT ANSWER-noninsulin- dependent diabetes vagus nerve - CORRECT ANSWER-the tenth cranial nerve, which supplies fibers to many parts of the body, including the ears, tongue, pharynx, larynx, and thoracic, and abdominal viscera vapocoolant - CORRECT ANSWER-a chemical spray applied to the skin to rapidly cool the skin surface vaporizer - CORRECT ANSWER-a device that allows for the controlled evaporation and release of inhalation anesthetic agents for the administration of inhalation anesthesia vasoconstriction - CORRECT ANSWER-the decrease in the diameter of a vessel, especially constriciton of arterioles leading to decreased blood flow to a part vascoconstrictors - CORRECT ANSWER-pharmacologic agents that cause blood vessels to con
