TNCC Notes for Written Exam 2024 What is kinematics? - Answer ️️ -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? - Answer ️️ -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? - Answer ️️ -Energy can neither be created nor destroyed. It is only changed from one form to another. What is Newton's Second Law? - Answer ️️ -Force equals mass multiplied by acceleration of deceleration. What is kinetic energy (KE)? - Answer ️️ -KE equals 1/2 the mass (M) multiplied by the velocity squared. What is the Mnemonic for the Initial Assessment? - Answer ️️ -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? - Answer ️️ -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? - Answer ️️ -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? - Answer ️️ -- Tracheal deviation - JVD What are signs of ineffective breathing? - Answer ️️ -- 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? - Answer ️️ -A tight-fitting nonrebreather mask at 12-15 lpm. What intervention should be done if a pt presents with effective circulation? - Answer ️️ -- Insert 2 large caliber IV's - Administer warmed isotonic crystalloid solution at an appropriate rate What are signs of ineffective circulation? - Answer ️️ -- Tachycardia - AMS - Uncontrolled external bleeding - Pale, cool, moist skin - Distended or abnormally flattened external jugular veins - Distant heart sounds What are the interventions for Effective/Ineffective Circulation? - Answer ️️ -- Control any uncontrolled external bleeding by: - Applying direct pressure over bleeding site - Elevating bleeding extremity - Applying pressure over arterial pressure points - Using tourniquet (last resort). - Cannulate 2 large-caliber IV's and initiate infusions of an isotonic crystalloid solution - Use warmed solution - Use pressure bags to increase speed of IVF infusion - Use blood administration tubing for possible administration of blood - Use rapid infusion device based on protocol - Use NS 0.9% in same tubing as blood product - IV = surgical cut-down, central line, or both. - Blood sample to determine ABO and Rh group - IO in sternum, legs, arms or pelvis - Administer blood products - PASG (without interfering with fluid resuscitation) How do you assess Mnemonic "D"? - Answer ️️ -DISABILITY A = Alert V = Verbal P = Pain U = Unresponsive - GCS - PERRL? - Determine presence of lateralizing signs including: - Unilateral deterioration in motor movements or unequal pupils - Symptoms that help to locate area of injury in brain What are the interventions for Disability? - Answer ️️ -- If assessment indicates a decreased LOC, conduct further investigation during secondary focused assessments - If pt is not alert or verbal, continue to monitor for any compromise to ABC's - If pt demonstrates signs of herniation or neurologic deterioration, consider hyperventilation. What is assessed and intervened for Expose/Environmental Controls? - Answer ️️ -- Remove clothing - Ensure appropriate decontamination if exposed to hazardous material - Keep pt warm - Keep clothing for evidence What is the first thing assessed under the Secondary Assessment? - Answer ️️ -FULL SET VS / FOCUSED ADJUNCTS / FAMILY PRESENCE - ABCDE should be completed - Labs, X-rays, CT, Foley, - Family Presence What is the second thing assessed under the Secondary Assessment? - Answer ️️ -GIVE COMFORT MEASURES - Talking to pt - Pharmacologic/Nonpharmacologic pain management - Observe for physical signs of pain What is assessed under the Mnemonic "H"? - Answer ️️ -HISTORY / HEAD-TO-TOE ASSESSMENT - MIVT - M = Mechanism of injury - I = Injuries sustained - V = Vital Signs - T = Treatment - Pt generated infor
