What is kinematics? - answer--A branch of mechanics (energy transfe r) 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 remai n 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 multipli ed by acceleration
of deceleration.
What is kinetic energy (KE)? - answer--KE equals 1/2 the mass (M) mu ltiplied by the velocity squared.
What is the Mnemonic for the Initial Assessment? - answer--A = Ai rway with simultaneous cervical spine protection
B = Breathing
C = Circulation
D = Disability (neurologic status)
E = Expose/Environmental controls (remove clothing and keep th e patient warm)
What is the Mnemonic for the Secondary Assessment? - answer--F = Ful l set of VS/Focused adjuncts (includes cardiac monitor, urinary catheter , and gastric tube)/Family presence
G = Give comfort measures (verbal reassurance, touch, and pharmacolo gic 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--Auscu ltate the lungs bilaterally at the second intercostal space midclavicular line an d at the fifth intercostal space at the anterior axillary line.
What are the late signs of breathing compromise? - answer--- Trach eal deviation - JVD
What are signs of ineffective breathing? - answer--- AMS - Cyanosis, especially around the mouth

lOMoARcPSD|17222949 - Asymmetric expansion of chest wall - Paradoxical movement of the chest wall during inspiratio n and expiration - Use of accessory muscles or abdominal muscles or both or diaphrag matic breathing - Sucking chest wounds - Absent or diminished breath sounds - Administer O2 via NRB or assist ventilations with a bag-mask d evice, as indicated - Anticipate definitive airway management to support venti lation.
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 e ffective circulation? - answer--- Insert 2 large caliber IV's - Administer warmed isotonic crystalloid solution at an approp riate 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 Circulati on? - 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 administratio n 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
Downloaded by Nelson Awino (nelawino@gmail.com)
lOMoARcPSD|17222949 - PERRL? - Determine presence of lateralizing signs including: - Unilateral deterioration in motor movements or unequal pu pils - 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 f ocused 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 dete rioration, consider hyperventilation.
What is assessed and intervened for Expose/Environmental Control s? - answer--- Remove clothing - Ensure appropriate decontamination if exposed to hazardo us 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 / HEA D-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"? - answer--INSPECT POSTE RIOR SURFACES - While maintaining C-spine, logroll pt with assistance to inspect back, flanks, buttocks and posterior thighs. - Palpate vertebral column for deformity and areas of tendern ess - Assess rectum for presence/absence of tone, presence of blood
