TNCC Notes for Written Exam
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
What are the interventions for Effective/Ineffective Circulation? -
✅ - 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"? -
✅ DISABILITY
, TNCC Notes for Written Exam LATEST

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? -
✅ - 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? -
✅ - 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? -
✅ 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? -
✅ GIVE COMFORT MEASURES
- Talking to pt
- Pharmacologic/Nonpharmacologic pain management
- Observe for physical signs of pain
What is assessed under the Mnemonic "H"? -
✅ HISTORY / HEAD-TO-TOE ASSESSMENT
- MIVT
- M = Mechanism of injury
- I = Injuries sustained
- V = Vital Signs
- T = Treatment
- Pt generated information
- PMH
- Head-to-toe assessment
What is assessed under the Mnemonic "I"? -
