Emergency Nursing
 Primary survey- focus on airway,
breathing, circulation, and disability,
exposure (ABCDE)
 Identifies life-threatening conditions
 If life-threatening conditions related
to ABCD identified during primary
survey interventions started immediately before procede to next step of
survey.

Primary Survey
 Airway with cervical spine stabilization and/or
immobilization
 Signs/symptoms compromised airway
 Dyspnea
 Inability to vocalize
 Presence of foreign body in airway
 Trauma to face or neck
•Maintain airway: least to most invasive method
Open airway using jaw-thrust maneuver.
Suction and/or remove foreign body.
Insert nasopharyngeal/oropharyngeal airway.
Provide endotracheal intubation

airway- Involves sedation or
anesthesia and paralysis

Jaw-Thrust
Maneuver
Fig. 69-2. Jaw-thrust maneuver is the recommended
procedure for opening the airway of unconscious patient with
a possible neck or spinal injury. Patient should be lying
supine with rescuer kneeling at top of the head. Rescuer
places one hand on each side of patient’s head, resting his or
her elbows on the surface. Rescuer grasps the angles of
patient’s lower jaw and lifts the jaw forward with both hands
without tilting the head.
Cricoid Pressure

the cricoid ring pushes the vocal cords downward toward
the field of vision while sealing the esophagus against

not give immediately before, with, or shortly
after charcoal
Dermal cleansing/eye irrigation
 Skin/ocular decontamination: removal of
toxins from skin/eyes using water or saline
 With the exception of mustard gas, toxins
can be removed with water/saline.
 Water mixes with mustard gas and
releases chlorine gas .
 **Decontamination takes priority over all
interventions except basic life support
measures.

42
Chemical Agents of Terrorism
 Categorized by target organ or effect


Sarin: toxic nerve gas >cause death within
minutes of exposure
 Enters body through eyes/skin
 Acts by paralyzing respiratory muscles
Antidotes for nerve agents: atropine,
pralidoxime chloride
Copyright © 2011, 2007 by Mosby, Inc., an affiliate of Elsevier Inc.
43
Chemical Agents of
Terrorism


Phosgene: colorless gas normally used in
chemical manufacturing
 If inhaled at high concentrations for long
enough period >severe respiratory distress,
pulmonary edema >death
Mustard gas: yellow to brown in color with
garlic-like odor
 Irritates eyes and causes skin burns/blisters
Copyright © 2011, 2007 by Mosby, Inc., an affiliate of Elsevier Inc.
44
Radiologic/Nuclear Agents of Terrorism
 Radiologic dispersal devices (RRDs) (“dirty bombs”):
mix of explosives and radioactive material
 When detonated, blast scatters radioactive dust,
smoke, and other material into
environment>radioactive contamination.
 Main danger from RRDs: explosion
 Ionizing radiation (e.g., nuclear bomb, damage to
nuclear reactor): serious threat to safety of casualties
and environment
 Exposure may or may not include skin contamination
with radioactive material.
 Initiate decontamination procedures
immediately if external radioactive
contaminants are present.
45
Explosive Devices as Agents of
Terrorism
 Result in one or more of following types of injuries:
blast, crush, or penetrating
 Blast injuries from supersonic overpressurization
shock wave that results from explosion
 Damage to lungs, middle ear, gastrointestinal
tract
 Emergency: any extraordinary event that requires
a rapid and skilled response and can be managed
by a community’s existing resources
 Mass casualty incident (MCI)
 Manmade or natural event or disaster that
overwhelms community’s ability to respond
with existing resources

Emergency and Mass Casualty
Incident Preparedness
 When an emergency or MCI occurs, first responders
(e.g., police, emergency medical personnel)
are dispatched.
 Triage of casualties differs from usual ED triage-is
conducted in <15 seconds.
 System of colored tags designates both seriousness of
injury and likelihood of survival.
 Green (minor injury)
 Yellow (urgent tag-noncritical injury.
 Red tag- life-threatening injury.
 Blue tag indicates those who are expected to die.
 Black tag identifies the dead.
Copyright © 2011, 2007 by Mosby, Inc., an affiliate of Elsevier Inc.
48
Emergency and Mass Casualty
Incident Preparedness
 Casualties need to be treated/stabilized.
If known or suspected contamination,
decontaminate at scene, then transport to
hospitals.
 Many casualties will arrive at hospitals on their
own (i.e., “walking wounded”).
 Total number of casualties a hospital can
expect-est by doubling #casualties that arrive
in 1st hour.
 Generally, 30%-require admission to
hospital, 1/2 will need surgery within 8
hours.


49
Emergency and Mass Casualty
Incident Preparedness
 Communities have initiated programs to
develop community emergency response
teams (CERTs).
 CERTs-partners in emergency
preparedness-training helps citizens to
understand their personal responsibility in
preparing for natural/manmade disaster.
 All health care providers have role in
emergency and MCI preparedness.
 Knowledge of the hospital’s emergency
response plan
 Participation in emergency/MCI
preparedness drills is required
Copyright © 2011, 2007 by Mosby, Inc., an affiliate of Elsevier Inc.
50
Emergency and Mass Casualty
Incident Preparedness
 Response to MCIs often requires aid of federal agency such as
the National Incident Management System (NIMS).
 Section within U.S. Department of Homeland Securityresponsible for coordination of federal medical response to
MCIs
 National Disaster Medical System: organizes and trains
volunteer disaster medical assistance teams (DMATs)
 DMATs: categorized according to ability to respond to an
MCI
51
Question
While performing triage in the emergency department, the
nurse determines that which of the following patients should
be seen first?
1. A patient with a deformed leg indicating a fractured tibia;
blood pressure 110/60 mm Hg, pulse 86 beats/min,
respirations 18 breaths/min.
2. A patient with burns on the face and chest; blood pressure
120/80 mm Hg, pulse 92 beats/min, respirations 24
breaths/min.
3. A patient with type 1 diabetes in ketoacidosis; blood
pressure 100/60 mm Hg, pulse 100 beats/min,
respirations 32 breaths/min.
4. A patient with a respiratory infection with a cough
productive of greenish sputum; blood pressure 128/86
mm Hg, pulse 88 beats/min, respirations 26 breaths/min.

52
Question
Assessment of the patient during the primary survey
indicates that the patient has delayed capillary refill of the
extremities and cannot explain the events prior to
admission to the emergency department. The nurse should
first:
1. Insert one or two large-bore IV catheters to start
intravenous fluid resuscitation.
2. Continue the primary survey to complete it with a brief
neurologic examination.
3. Apply leads for electrocardiogram (ECG) monitoring.
4. Initiate pulse oximetry.

53
Question
Several patients are admitted to the emergency
department after exposure to an aerosolized agent that is
believed to be a hemorrhagic fever virus used as a
bioterrorism agent. The nurse plans care for the patients
with the knowledge that:
1. No known treatment is available for this disease.
2. A vaccine is available to prevent the disease in those
who have been exposed.
3. The disease can be spread from person to person only
by vectors such as mosquitoes or fleas.
4. Ciprofloxacin (Cipro) is the treatment of choice and is
stockpiled by government agencies for use against the
virus.
