Priority Emergency
Measures for
All Patients
Make safety the first priority
Preplan to ensure security and a safe
environment
Closely observe patient and family
members in the event that they
respond to stress with physical
violence
Assess the patient and family for
psychological function
Patient and family-focused
interventions
Relieve anxiety and provide a sense
of security
Allow family to stay with patient, if
possible, to alleviate anxiety
Provide explanations and information
Provide additional interventions
depending upon the stage of crisis

Triage
Means: to sort: ED triage differs from disaster
triage in that patients who are the most critically
ill receive the most resources, regardless of
potential outcome
1. Across-the-room assessment
starts with visual contact, general
appearance, work of breathing, skin color
2. Determine chief complaint
3. Focused assessment
(Subjective data) demographics, onset of
symptoms, past medical history, LMP, current
meds, allergies
(Objective data) inspection, palpation,
auscultation, obtain vital signs
Primary Survey
A: Airway
patency, stridor, inability to speak, rise
and fall of chest
B: Breathing
rate and depth, breath sounds, chest
expansion, skin color, spontaneous
breathing
C: Circulation
heart rate, pulses, blood pressure, skin,
cap refill
D: Disability Alertness, Responsive to Voice,
Responsive to pain, Unresponsiveness
E: Exposure
Remove clothing, keep pt warm
Priorities of Care for the
Patient With Multiple
Trauma
Use a team approach
Determine the extent of injuries and
establish priorities of treatment
Assume cervical spine injury-log roll
protect spine
Assign highest priority to injuries
interfering with vital physiologic
function
A client arrives in the emergency room with multiple
crushing wounds of the chest, abdomen, and legs. The
assessments that assume the greatest priority are: select all
that apply:
A. Level of consciousness and pupil size
B. Abdominal contusions and other wounds
C. Pain, respiratory rate, and blood pressure
D. Quality of respirations and presence of pulses
A.Level of
consciousness and pupil
size
Rationale:
This is an assessment
for head injury that
follows determination of
respiratory and
circulatory status
C.Pain, respiratory rate,
and blood pressure
Rationale:
Pain assessment would
follow the appraisal of
airway, breathing, and
circulation.
 You are preparing to suction a client with a trach.
List the order of priority for the actions to take
during this procedure.
 ____ hyperoxygenate the client
 ____ Place the client in a semi fowler position
 ____ turn the suction on and set regulator to 80 mmHG
 ____ Apply gloves and attach the suction tubing to the
suction catheter
 ____ Insert the Catheter into the trach until resistance is
met and pull back 1 cm
 ____
Apply intermittent suction and slowly withdraw
while rotating it back and forth
You are the triage nurse coming on
duty. The following patients come
in to be seen. This is all the info
you have. How would you triage
them and why?

Management of Patients With Heat
Stroke
 Remember ABCs (decrease temp
to 39° C as quickly as possible
 Cooling methods
 Cooling
blankets, cool sheets, towels,
or sponging with cool water
 Apply
ice to neck, groin, chest, and
axillae
 Iced lavage of the stomach or colon
 Immersion in cold water bath
 Monitor
temp, VS, ECG, CVP, LOC,
urine output
 Use IVs to replace fluid losses
–Hyperthermia may recur in 3 to 4
hours; avoid hypothermia
Ensure adequate fluid and
foods intake
Prevent overexposure to sun
Use sunscreen with at least
SPF 30
Rest frequently when in hot
environment
Gradually expose self to heat
Wear light weight, light
colored, loose clothing
Pay attention to personal
limitations: modify
accordingly

HYPOTHERMIA
 Most common


Hypothermia
Frostbite
 Synthetic clothing is best because it
wicks away moisture and dries fast
 “cotton kills” it holds moisture and
promotes frostbite
 A hat is essential to prevent heat loss
though head
 Keep water, extra clothing, and food in
car in case of break down
Hypothermia






Internal core temperate is 35° C or less
Elderly, infants, persons with concurrent
illness, the homeless, and trauma victims
are at risk
Alcohol ingestion increases susceptibility
Hypothermia may be seen with frostbite;
treatment of hypothermia takes
precedence
Physiologic changes in all organ systems
Monitor continuously
 Apathy, drowsiness,
pulmonary edema,
coagulopathies
 Weak HR and BP
 Hypoxemia
 Continuous
temperature and EKG
 Watch for dysrhythmias
 Warm fluids, blankets
 Cardiopulmonary bypass
 Warm lavage
Frost Bite
 Inadequate insulation is the culprit
 3 stages



Superficial (frost nip)
Mild
Severe




1st degree- hyperemia, edema
2nd degree- fluid blisters with partial thick necrosis
3rd degree- dark fluid blisters, sub cutaneous necrosis
4th degree- no blisters, no edema, necrosis to muscle and
bone
 Frostnip produces mild pain,
numbness,pallor of affected skin
 Graded like burns-partial thick or full thick
 Most species non venomous and
harmless
 Poisonous snakes found in each
state except Maine, Alaska, and
Hawaii
Fatalities are few
 Children 1-9 yrs old victims during
daylight hours
 AWARENESS is KEY
2 main types in North America are
 1.
 2.


 Pit Vipers


Depression between eye and
nostril
Triangular head indicative of
venom



Venom function is to immbolize, kill
and aid in digestion of prey
(systemic effects happen with in 8
hours of puncture)








impairs blood clotting
Breaks down tissue protein
Alters membrane integrity
Necrosis of tissues
Swelling
Hypovolemic shock
Pulmonary edema, renal failure
DIC
2 retractable curved fangs with
canals
Rattlers have horny rings in tail
that vibrates as a warning

Treatment



Avoid venomous snakes as pets
Be cautious in areas that harbour
snakes like tall grass, rock piles,
ledges, crevices, caaves, swamps
Don protective attire like boots, heavy
pants and leather gloves. Use a
walking stick
Inspect areas before placing hands or
feet in them
Do not harass snakes….striking
distance is the length of the snake
Snakes can bite even 20—60 minutes
after death due to bite reflex
Use caution when transporting snake
with victim to hospital…make sure it is
in a sealed container.

 Each day in the United States, nine people drown.
 Drowning is the second leading cause of
accidental injury-related death among children
ages 1 to 14.
 Drowning is the leading cause of accidental
injury-related death among children ages 1 to 4.
 Male children have a drowning rate more than
two times that of female children. However,
females having a bathtub drowning rate twice
that of males.
 Among children ages 1 to 4 years, most

drownings occur in residential swimming pools.








More than half of drownings among infants (under age 1) occur in
bathtubs, buckets or toilets.
Nonfatal drownings can result in brain damage that may result in
long-term disabilities including memory problems, learning
disabilities, and permanent loss of basic functioning.
Nineteen percent of child drowning fatalities take place in public
pools with certified lifeguards on duty.
Roughly 5,000 children 14 and under go to the hospital because
of accidental drowning-related incidents each year; 15% die and
about 20% suffer from permanent neurological disability.
In nearly 9 out of 10 child-drowning deaths, a parent or caregiver
claimed to be watching the child.
Participation in formal swimming lessons can reduce the risk of
drowning by 88% among children ages 1-4.
2011 Drowning Statistic
Between Memorial Day June 28, 2011, there were 48 drownings
and 75 near-drowning events in 35 states and territories.

 First Aid
 When someone is drowning:
 Extend
a long pole or branch to the person, or use a
throw rope attached to a buoyant object, such as a life






ring or life jacket. Toss it to the person, then pull him or
her to shore.
People who have fallen through ice may not be able to
grasp objects within their reach or hold on while being
pulled to safety.
Do not place yourself in danger.
Do NOT get into the water or go out onto ice unless your
are absolutely sure it is safe.
If you are trained in rescuing people, do so immediately
if you are absolutely sure it will not cause you harm.
If the victim's breathing has stopped, begin rescue
breaths as soon as you can. This often means starting the
breathing process while still in the water.
Continue to breathe for the person every few seconds
while moving them to dry land. Once on land, give CPR if
needed. For step-by-step instructions on rescue
breathing, see the article on CPR.
Always use caution when moving a drowning victim.
 Assume that the person may have a neck or spine injury, and
avoid turning or bending the neck.
Keep the head and neck very still during CPR and while moving
the person.
You can tape the head to a backboard or stretcher, or secure the
neck by placing rolled towels or other objects around it.
Follow these additional steps:
Keep the person calm and still. Seek medical help immediately.
Remove any cold, wet clothes from the person and cover with
something warm, if possible. This will help prevent hypothermia.
Give first aid for any other serious injuries.
The person may cough and have difficulty breathing once breathing restarts. Reassure the person until you get medical help.

DO NOT
DO NOT go out on the ice to rescue a drowning person that you can
reach with your arm or an extended object.
DO NOT attempt a swimming rescue yourself unless you are
trained in water rescue.
DO NOT go into rough or turbulent water that may endanger you.
When to Contact a Medical Professional
If you cannot rescue the drowning person without endangering
yourself, call for emergency medical assistance immediately. If you
are trained and able to rescue the person, do so and then call for

All near-drowning victims should be checked by a doctor. Even
though victims may revive quickly at the scene, lung complications
are common.
 Prevention
 Avoid drinking alcohol whenever swimming or boating.
 Observe water safety rules.
 Take a water safety course.
 Never allow children to swim alone or unsupervised
regardless of their ability to swim.
 Never leave children alone for any period of time, or let
them leave your line of sight around any pool or body of
water.
 Drowning can occur in any container of water. Do not
leave any standing water (in empty basins, buckets, ice
chests, kiddy pools, or bathtubs). Secure the toilet seat
cover with a child safety device.
 Fence all pools and spas. Secure all the doors to the
outside, and install pool and door alarms.
 If your child is missing, check the pool immediately.

Wound Care Treatment (at Site)
 Bleeding can usually be stopped by applying direct pressure
to the wound.
 Very large foreign objects stuck in a wound should be
stabilized. Do not remove them.
 All wounds require immediate thorough cleansing with fresh
tap water.
 Gently scrub the wound with soap and water to remove
foreign material.
 Remove dead tissue from the wound with a sterile scissors or
scalpel.
 After cleaning the wound, a topical antibiotic ointment
(bacitracin) should be applied 3 times per day.
 Wounded extremities should be immobilized and elevated.
 Puncture wounds are usually not sutured (stitched) unless
they involve the face.


If the wound is clean, the edges can be drawn together
with tape.
 (Do
not cover wounds inflicted by animals or
that occurred in seawater with tape.)
Oral antibiotics are usually recommended to prevent
infection.
 Ifleast
infection develops, continue antibiotics for at
5 days after all signs of infection have



cleared.
Inform the doctor of any drug allergy prior to
starting any antibiotic. The doctor will
prescribe the appropriate antibiotic. Some may
cause sensitivity to the sun, so sunscreen (at
least SPF 15) is mandatory while taking these
antibiotics.
Pain may be relieved with 1-2 acetaminophen (Tylenol)
every 4 hours, 1-2 ibuprofen (Motrin, Advil) every 6-8
hours, or both.
Call 911 or get to ER immediately if stab or gunshot
wound.
In Hospital Treatment
•Stay Safe. Utilize universal precautions and wear personal protective equipment if
available.
•Control bleeding before anything else. Putting pressure directly on the puncture
wound while holding it above the level of the heart for 15 minutes should be enough
to stop bleeding.
• If not, try using pressure points. Tourniquets should be avoided unless medical
care will be delayed for several hours.
•Holes in the chest can lead to collapsed lungs.
• Deep puncture wounds to the chest should be immediately sealed by hand or
with a dressing that does not allow air o flow. Victims may complain of shortness
of breath. If the victim gets worse after sealing the chest puncture wound, unseal
it.
•Once bleeding has been controlled, wash the puncture wound with warm water and
mild soap . If bleeding starts again, repeat step two.
Sexual abuse (also referred to as molestation)
is defined as the forcing of undesired sexual acts
by one person to another. The term incest is
defined as sexual abuse between family
members, and the euphemism "bad touch" is
sometimes used to describe such abuse.
(Renvoizé 1982)
Different types of sexual abuse involve:

Non-consensual, forced physical sexual behavior such
as rape or sexual assault
Psychological forms of abuse, such as verbal sexual
behavior or stalking.
The use of a position of trust for sexual purposes.
Acquaintance rape - forced sexual intercourse
between individuals who know each other - is a
crime that is widespread on many college and
university campuses.
 Usually, both parties involved in acquaintance rape
have been drinking - often to excess.
Research has not yet explained how and why
alcohol is related to aggression in general or to
acquaintance rape in particular

 The doctor in the emergency room will
examine the victim for injuries and collect
evidence.

The attacker may have left behind pieces of evidence such as
clothing fibers, hairs, saliva or semen that may help identify him.

In most hospitals, a "rape kit" is used to help collect evidence.
A rape kit is a standard kit with little boxes, microscope slides
and plastic bags for collecting and storing evidence. Samples
of evidence may be used in court.

Next, the doctor will need to do a blood test. Women will be
checked for pregnancy and all rape victims are tested for
diseases that can be passed through sex.
 Cultures of the cervix may be sent to a lab to check for
disease, too. The results of these tests will come back in
several days or a few weeks.

It's important for the client to see their own doctor in 1 or 2 weeks
to review the results of these tests. If any of the tests are positive,
the victim will need to talk with your doctor about treatment.

treatments.
The emergency room doctor can tell the victim about different
pregnancy

is small.
the chance of
prevention
If no birth control is taken the victim may consider pregnancy
treatment.
first
Pregnancy prevention consists of taking 2 estrogen pills when you
get to the hospital and 2 more pills 12 hours later. This treatment
reduces the risk of pregnancy by 60% to 90%. (The treatment may
make you feel sick to your stomach.)
about
The risk of getting a sexually transmitted disease during a rape is
5% to 10%. Your doctor can prescribe medicine for chlamydia,
gonorrhea and syphilis when the victim first gets to the hospital.
vaccination
If not already vaccinated for hepatitis B, the victim should get that
when you first see the emergency room doctor. Then
they’ll get another vaccination in 1 month and a third in 6 months.
infection.
The doctor will also discuss human immunodeficiency virus (HIV)
Your chance of getting HIV from a rape is less than 1%, but if
you want preventive treatment, you can take 2 medicines-- zidovudine
(brand name: Retrovir) and lamivudine (brand name: Epivir) -- for 4
weeks.

Trauma from the blast
thermal burns from the heat and light
acute radiation syndrome from exposure to the nuclear radiation
Exposure to radiation Is affected by time, distance, and shielding
RADIOLOGIC AGENTS


Nonionizing - low energy and non-harmful
Ionizing – Alpha, Beta and Gamma
Alpha – poorly penetrates skin, travel 12 inches, very harmful to kidneys lungs
and skeletal system if introduced
through broken skin or ingested



Beta – can penetrate skin at short
distances causing burns, travels up to
10 ft., can be harmful if ingested or
inhaled


Blocked by clothing or paper
Blocked by heavy clothing, walls, or thin
metals
Gamma – emitted during nuclear
detonation and are present in fall out,
travel several 100 ft., are penetrating
through tissue to deep organs.

Blocked by dense materials – lead,
concrete, and steel
 An acute illness that occurs
when the entire body (or most
of it) receives or is exposed to
a high dose of radiation.
 Generates highly reactive free
radicals, damages messenger
RNA (mRNA) and DNA and
interferes with cell growth, or
even causes cell death.
 Severity varies with the
amount of exposure, age and
overall heath of an individual
Radiation Decontamination
 Triage outside the hospital
 Cover floor and use strict isolation
precautions to prevent the tracking of
contaminants
 Seal air ducts and vents
 Waste is double bagged and put in a
container labeled radiation waste
 Staff protection
 Water-resistant gowns, 2 pairs of
gloves, caps, goggles, masks, and
booties

Decontamination
EXPLOSIVE AGENTS
 High Order Explosive
(nitroglycerin) and Low
Order Explosives
(pyrotechnics,
gunpowder)
 High Order Explosive
Injuries are classified into
Primary, Secondary and
Tertiary.
Blast Injuries from High Order
Explosives

Nail Bomb or Jar Bomb



Primary – Impact of the
overpressurization wave
with body surfaces –
lungs, ears, GI,
TBI (most)
Secondary – Flying debris
and bomb
fragments
Tertiary – Injuries incurred
from
being
thrown by the blast.
Quaternary – explosion
related
injuries that are
complication of the
previous
injuries
Psychological Effects After a
Disaster




Provide active listening and emotional support

Encourage return to normal activities and social
roles
Provide information as appropriate
Refer to therapist or other resources
Discourage repeated exposure to media
regarding the event
 Strategic National Stock Pile






Push Packs-shipped within 12
hours of the decision to deploy
4% of the stockpile
Antibiotic agents
IV/IM medications
Bulk Supplies-First Aid
Analgesics
Other Emergency Medications
DMAT/DMORTS
Disaster Management Assistance Teams/Disaster
Management Mortuary Teams
 Health care providers, nurses, EMT’s, Technical Staff, and
other health care professionals.
 DMORTS – management and identification of the dead
The point is
to save as
many as you
can
