Primary concern when a person cannot stop coughing/clearing their throat following

have the same symptoms. What is the most likely cause? - ANSWER- Biologic

Suspected shock type with a spinal cord injury - ANSWER- Distributive Shock (Includes
neurogenic)

is the cause? - ANSWER- Herniation

Middle Meningeal Artery - ANSWER- Epidural Hematoma (results from collection of
blood that forms between dura mater and skull)

healed. What is the cause? - ANSWER- 2nd Impact Syndrome

diaphragm

Symptoms of __________________: include muffled heart sounds and hypotension -
ANSWER- Pericardiocentesis

How should you dress a severed limb? - ANSWER- Sterile gauze with normal saline
THEN put ice on it

Amylase level looks at _____________ - ANSWER- Pancreas

What should you do if your patient has hyphema (collection of blood inside the front part
of the eye?) - ANSWER- Sit HOB up to 30 degrees

Principle that people have to take action after suffering a loss in order to decrease
severity, seriousness, or painfulness - ANSWER- Mitigation

What organ is most at risk following a gunshot - ANSWER- Liver

,8 year old child with longitudinal thigh lacerations - ANSWER- Sign of child abuse

Bleeding around belly button - ANSWER- Cullen's Sign

What would cause an inaccurate reading from an 02 saturation probe? - ANSWER-
Carboxyhemoglobin (increase FiO2 to 100%)

General study of forces and their effects on living tissue and the human body -
ANSWER- Biomechanics

Study of energy transfer as it applies to identifying actual or potential injuries -
ANSWER- Kinematics

Refers to the separation of tissue resulting from a sound and/or hydraulic wave force-
the effect is a crushing pressure wave which creates a temporary cavity, followed by a
rapid and violent closing of the cavity. - ANSWER- Cavitation

This rapid motion can lead to crushing, tearing, and shearing forces on tissue -
ANSWER- Cavitation

Used in OR; does not provide protection against aspiration and not recommended in
patients who have eaten recently. It is a supraglottic airway. - ANSWER- Laryngeal
Mask Airway

Single tube retroglottic device inserted into the esophagus and traps the glottis opening
between an esophageal cuff and an oropharyngeal cuff. Designed with 2 ports/lumens
each with a separate cuff. Does NOT provide protection against aspiration and is not
indicated in children. It is a retroglottic airway. - ANSWER- King Tube

Types of Shock (4) - ANSWER- Hypovolemic, Obstructive, Cardiogenic, Distributive

Hemorrhage is the leading cause. Can result from vomiting, diarrhea, and burn trauma.
Decreased circulating volume --> decreased preload. Therapy includes replacing the
type of volume that was lost. - ANSWER- Hypovolemic Shock

Results from hypo perfusion of tissue due to an obstruction in either the vasculature or
heart. Therapy aimed at relieving the obstruction and improving perfusion. - ANSWER-
Obstructive Shock

Two classic examples of obstructive shock - ANSWER- Cardiac tamponade and tension
pneumothorax

Results from pump failure in the presence of adequate intravascular volume. Lack of
CO and end-organ perfusion secondary to a decrease in myocardial contractility and/or
valvular insufficiency. Therapy includes inotropic support, antidysrhythmic medications,
and correction or treatment of underlying cause. - ANSWER- Cardiogenic Shock

,Results from the misdistribution of an adequate circulating blood volume with the loss of
vascular tone or increased permeability. Treatment is to provide volume replacement,
increase systemic vascular resistance with medications (pressors) and possible
antibiotics. - ANSWER- Distributive Shock

Examples that can cause distributive shock - ANSWER- Anaphylactic shock, septic
shock, neurogenic shock

___________________: Impairs thrombin production and platelet function
_____________ ______________: Impairs thrombin production
_______________________: Results in depletion of clotting factors through
hemodilution and the impaired ability to produce clotting factors. - ANSWER- Trauma
Triad of Death
1. Hypothermia
2. Metabolic Acidosis
3. Coagulopathy

Stages of Shock (3) - ANSWER- 1. Compensated
2. Decompensated vs Progressive
3. Irreversible

Complete craniofacial separation involving maxilla, zygoma, orbits, and bones of the
cranial base. Assessment findings include: massive facial edema, mobility and
depression of zygomatic bones, ecchymoses, diplopia, and open bite or malocclusion. -
ANSWER- LeFort III

Transverse maxillary bone fracture that occurs above the level of the teeth from the
maxilla. Assessment findings include: independent moment of the maxilla from the rest
of the face, slight swelling of the maxillary area, lip laceration or fractured teeth,
malocclusion. - ANSWER- LeFort I

Pyramidal maxillary bone fracture involving the mid-face area. The apex of the fracture
transverses the bridge of the nose. Assessment findings include: massive facial edema,
nasal swelling with obvious fracture of the nasal bones, malocclusion, CSF rhinorrhea -
ANSWER- LeFort II

Can be caused by blunt trauma. Air escapes from the injured lung into the pleural
space, and negative intrapleural pressure is lost resulting in partial or complete collapse
of the lung. S & S: dyspnea, tachypnea, decreased/absent breath sounds on injured
side, chest pain. Treatment: based on size, symptoms, and stability. Chest tube may be
placed to evacuate pleural air and maintain lung expansion - ANSWER- Pneumothorax

Air enters the intrapleural space but cannot escape on expiration. The increasing
intrathoracic pressure causes the lung on the injured side to collapse. If pressure is not
relieved, the mediastinum can shift toward the uninjured side compressing the

, heart/great vessels/and opposite lung. S & S: anxiety, severe restlessness, severe
respiratory distress, significantly diminished or absent breath sounds on injured side,
hypotension, distended neck/head/upper extremity veins, tracheal deviation, or a shift
toward uninjured side. Treatment: Needle thoracentesis and chest tube insertion -
ANSWER- Tension Pneumothorax

Collection of blood in pericardial sac. Mechanism of injury is typically penetrating
trauma. Compresses the heart and decreases ability of the ventricles to fill causing
decreased SV and CO. S & S: hypotension, muffled heart sounds, distended neck
veins, tachycardia or PEA, dyspnea, cyanosis, chest pain. Surgical evacuation will be
needed. - ANSWER- Cardiac Tamponade

__________________ Shock: Spinal cord injury at T6 or above. Temporary loss of
vasomotor tone and sympathetic innervation. Temporary duration usually <72 hours. S
& S: hypotension, bradycardia, loss of ability to sweat below level of injury. - ANSWER-
Neurogenic

______________ Shock: Spinal cord injury at any level. Transient loss of reflex below
the level of injury. Variable duration. S & S: flaccidity, loss of reflexes, bowel/bladder
dysfunction. - ANSWER- Spinal

Significant muscle damage and cellular destruction releases myoglobin: a muscle
protein; into the bloodstream. Classic symptoms: muscle pain/numbness/changes in
sensation, muscle weakness/paralysis, dark red/brown urine. - ANSWER-
Rhabdomyolysis

What does MIST mnemonic mean? - ANSWER- M: Mechanism of Injury
I: Injuries sustained
S: S&S in the field
T: Treatment in the field

Older adults are harder to intubate due to ______________ ____________ - ANSWER-
cervical arthritis

Leading cause of preventable death after injury - ANSWER- Hemorrhage

1 Liter of O2 = ____% FiO2 - ANSWER- 4%

Patient snoring = insert __________ airway - ANSWER- Oral Airway (OPA)

Avoid _______________ when administering oxygen/ventilation - ANSWER- hyperoxia

Resuscitation Adjuncts (LMNOP) - ANSWER- L: Lab
M: Monitor cardia rhythm and rate
