TNCC Notes for Written Exam
What is kinematics? - answer--A branch of mechanics (energy transfer) that refers to motion and does not consider the
... [Show More] 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 [Show Less]
