DAANCE STUDY QUESTIONS 2026 FULL
SOLUTIONS WITH CORRECT ANSWERS
GRADED A+
⩥ Wakefullness system. Answer: consists of a central core in the
brainstem with neurons that radiate to the cortex
⩥ Vomiting Center. Answer: the center in the brainstem that induces
vomiting
⩥ Vital Centers. Answer: centers in the brainstem that control such
physiologic processes as blood pressure and pulse, depth and rate of
respiration
⩥ Vestibular nerve. Answer: part of the eighth cranial nerve that is
connect with equilibrium and hearing
⩥ Venule. Answer: any of the small vessels that collect blood from
networks of capillaries and join them to form veins
⩥ Ventricular tachycardia. 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. Answer: a cardia dsrhythmia in which the
pacemaker is in the ventricles rather than in the SA node or atria
⩥ Ventricular focus. Answer: a displace point of origin for a
dysrhythmia that is in the ventricles
⩥ Ventricular fibrillation. Answer: arrhythmia characterized by
contractions of ventricle muscle fibers due to rapid excitation of
myocardial fibers without coordinated contraction of the ventricle
⩥ Sensory nerve. Answer: a nerve of the peripheral nervous system that
conducts impulses from a sense organ to the spinal cord or brain
⩥ Sinoatrial node. Answer: a microscopic collection of heart muscle
fibers where cardiac rhythm originates; also called the pacemaker of the
heart
⩥ sinus arrhythmia. Answer: a cardiac dysrhythmia similar to normal
sinus rhythm, but withslight variation in rate with inspiration and
expiration
⩥ sinus bradycardia. Answer: cardiac dysrhythmia similar to normal
sinus rhythm except for a slower rate of less than 60 bpm
, ⩥ sinus rhythms. Answer: cardiac rhythms in which the pacemaker is the
sinoatrial node
⩥ sinus tachycardia. 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. Answer: the amount of blood ejected from a ventricle
during each beat of the heart
⩥ subcutaneous. Answer: beneath the skin
⩥ superior vena cava. 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. Answer: central points of origin of dsrhythmias,
which are located above the level of the ventricles in the atria
⩥ sympathommimetic. Answer: having activity that mimics the effects
of the sympathetic nervous system, epinephrine
⩥ synapse. Answer: the junction between two neurons where impulses
are transmitted from one neuron to another
