TNCC Notes for Written Exam 2022

TNCC Notes for Written Exam 2022 What is kinematics? - A branch of mechanics (energy transfer) that refers to motion and does not consider the concepts of force and mass of the object or body. What is Newton's First Law? - A body at rest will remain at rest. A body in motion will remain in motion until acted on by an outside force. What is the Law of Conservation of Energy? - Energy can neither be created nor destroyed. It is only changed from one form to another. What is Newton's Second Law? - Force equals mass multiplied by acceleration of deceleration. What is kinetic energy (KE)? - KE equals 1/2 the mass (M) multiplied by the velocity squared. What is the Mnemonic for the Initial Assessment? - A = Airway with simultaneous cervical spine protection B = Breathing C = Circulation D = Disability (neurologic status) E = Expose/Environmental controls (remove clothing and keep the patient warm) What is the Mnemonic for the Secondary Assessment? - F = Full set of VS/Focused adjuncts (includes cardiac monitor, urinary catheter, and gastric tube)/Family presence G = Give comfort measures (verbal reassurance, touch, and pharmacologic and nonpharmacologic management of pain). H = Hx and Head-to-toe assessment I = Inspect posterior surfaces Where do you listen to auscultate breath sounds? - Auscultate the lungs bilaterally at the second intercostal space midclavicular line and at the fifth intercostal space at the anterior axillary line. What are the late signs of breathing compromise? - - Tracheal deviation - JVD What are signs of ineffective breathing? - - AMS - Cyanosis, especially around the mouth - Asymmetric expansion of chest wall - Paradoxical movement of the chest wall during inspiration and expiration - Use of accessory muscles or abdominal muscles or both or diaphragmatic breathing - Sucking chest wounds - Absent or diminished breath sounds - Administer O2 via NRB or assist ventilations with a bag-mask device, as indicated - Anticipate definitive airway management to support ventilation. Upon initial assessment, what type of oxygen should be used for a pt breathing effectively? - A tight-fitting nonrebreather mask at 12-15 lpm. What intervention should be done if a pt presents with effective circulation? - - Insert 2 large caliber IV's - Administer warmed isotonic crystalloid solution at an appropriate rate What are signs of ineffective circulation? - - Tachycardia - AMS - Uncontrolled external bleeding - Pale, cool, moist skin - Distended or abnormally flattened external jugular veins - Distant heart sounds W
