motion and does not consider the concepts of force and mass of the
object or body.


Question: What is Newton's First Law?

⼀Answer:⼀ A body at rest will remain at rest. A body in motion will

remain in motion until acted on by an outside force.


Question: What is the Law of Conservation of Energy?

⼀Answer:⼀ Energy can neither be created nor destroyed. It is only

changed from one form to another.


Question: What is Newton's Second Law?

⼀Answer:⼀ Force equals mass multiplied by acceleration of

deceleration.


Question: What is kinetic energy (KE)?

, Page | 2

⼀Answer:⼀ KE equals 1/2 the mass (M) multiplied by the velocity

squared.


Question: What is the Mnemonic for the Initial Assessment?

⼀Answer:⼀ 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)


Question: What is the Mnemonic for the Secondary Assessment?

⼀Answer:⼀ 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


Question: Where do you listen to auscultate breath sounds?

⼀Answer:⼀ Auscultate the lungs bilaterally at the second intercostal

space midclavicular line and at the fifth intercostal space at the
anterior axillary line.

Question: What are the late signs of breathing compromise?

⼀Answer:⼀ - Tracheal deviation

- JVD


Question: What are signs of ineffective breathing?

⼀Answer:⼀ - 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.


Question: Upon initial assessment, what type of oxygen should be
used for a pt breathing effectively?

⼀Answer:⼀ A tight-fitting nonrebreather mask at 12-15 lpm.


Question: What intervention should be done if a pt presents with
effective circulation?

⼀Answer:⼀ - Insert 2 large caliber IV's

- Administer warmed isotonic crystalloid solution at an appropriate
rate


Question: What are signs of ineffective circulation?

⼀Answer:⼀ - Tachycardia

- AMS
- Uncontrolled external bleeding
- Pale, cool, moist skin
- Distended or abnormally flattened external jugular veins
- Distant heart sounds


Question: What are the interventions for Effective/Ineffective
Circulation?

⼀Answer:⼀ - 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
