DAANCE Exam Wave of Depolarization - an advancing wave of charge reversal as the nerve impulse advance a long the neuron Wakefullness system - consists of a central core in the brainstem with neurons that radiate to the cortex

DAANCE module 1 CNS- Central Nervous System - composed of cerebrum,cerebellum & Medulla oblongata PNS-Peripheral Nervous System - Composed of Cranial Nerves (optic,olfactory,auditory,trigeminal & facial) & spinal nerve

DAANCE module 1 Myocardium - Cardiac Muscle In what order does blood flow through the heart - Right atrium, tricuspid valve, right ventricle, pulmonary artery, lungs, pulmonary vein, left atrium, Mitral valve, left ventricle , aorta.

DAANCE module 1 Myocardium - specialized muscle, unique ability to contract on its own. w/out stimulation by nerves The heart has four chambers, what are they? - Two upper chambers receive blood are called Atria. The left atrium receives blood from the lungs via the pulmonary vein and is oxygen-rich; the right atrium receives blood from the peripheral curculation (THE BODY) and is oxygen-poor.

DAANCE module 1 Neurons- what are they? - Cells of the nervous system Action potential- what is it? - The nerves threshold of stimuli Terminal button- what is it? - The bulge at the end of the nerve touches the next nerve

DAANCE module 1 Nervous and endocrine system - What are the two systems that provide overall control of body function? Central Nervous System, Peripheral Nervous System, and Autonomic Nervous System - What are the three subdivisions within the Nervous System?

DAANCE module 1 Heart Sequence - Right atrium, right ventricle, pulmonary artery, pulmonary vein, left atrium, left ventricle, aorta Peripheral Nervous System - Cranial nerves(optic, olfactory, auditory, facial, trigeminal) & spinal

DAANCE module 2 4 key medical history questions - Current medical conditions/under physician care Prior hospitalizations/ surgeries Current meds Allergies & reactions

DAANCE module 2 A pt who has a history of TIA's had a temporary lessening of - Blood sipply to the brain Ischemic heart disease is a result of - decreased blood flow in the coronary arteries

DAANCE module 2 Ischemia - A decrease in the blood flow in the coronary arteries that can temporarily or permanently damage heart muscles by decreasing the available oxygen to the heart muscles

DAANCE Module 3: Anesthetic Drugs and Techniques Diazepam (Valium) is used in outpatient oral and maxillofacial surgery to - Sedate the patient

DAANCE Module 3: Anesthetic Drugs and Techniques Brevital (Sodium Methohexital) - Primary anesthetic agent introduced in the 1960's. Balanced Anesthesia - Use of several agents together

DAANCE Module 3: Anesthetic Drugs and Techniques Brevital (Sodium Methohexital) - ultra short acting barbiturate. cardio effects : decrease in BP with a compensatory increase in HR.

DAANCE Module 3 5 primary areas where anesthetics work - 1)center of emotion versed 2)wakefulness center propofol 3)relay center ketamine 4)opoid receptors 5)vitals center

DAANCE Module 3 Local Anesthetic - Non-bupivacaine injection for pain control Vasoconstrictors - Added to anesthetics to prolong action by constricting blood vessels

ITLS Pre - Test A 25-year-old female was stabbed in the left arm. She presents with an altered mental status and signs of shock. Bleeding is controlled by direct pressure and use of a tourniquet. Which intravenous fluid therapy is appropriate? A. Estimate blood loss and administer fluid at a 3:1 ratio B. Fluid administration of 250 mL C. Fluid administration to maintain systolic pressure of 60 mmHg D. Intravenous fluid administration bolus of 500 mL, then reassess - D. Intravenous fluid ...

DAANCE Module 3 Purpose of the scavenging system - Reducing the levels of the noxious agents to an acceptably low level by exhausting them outside the operating room.
