◉ Maintain airway. Answer: o Suction and/or remove foreign body
o Insert nasopharyngeal/oropharyngeal airway
o Endotracheal intubation
o Cricothyroidotomy or tracheostomy
◉ Stabilize/immobilize cervical spine. Answer: Collar
Spinal precautions
Flat bedrest
Log roll
◉ Breathing. Answer: Assessment
Administer high-flow O2 via a nonrebreather mask
Bag-valve-mask (BVM) ventilation with 100% O2 and intubation for
life-threatening conditions
Monitor patient response
◉ Circulation. Answer: Check central pulse
Assess skin color, temperature, moisture
,Assess mental status and capillary refill
Aggressive fluid resuscitation
· Insert two large-bore IV catheters
· NS or LR
◉ Disability. Answer: LOC
AVPU
o A=alert
o V=responsive to voice
o P=responsive to pain
o U=unresponsive
GCS
Pupils
◉ Exposure. Answer: clothing removal/temperature control
◉ The nurse performing a primary survey in the ED is assessing.
Answer: the acuity of the patient's condition to determine priority of
care
the status of airway, breathing, circulation, or presence of deformity.
whether the patient is responsive enough to provide needed
information
,whether the resources of the ED are adequate to treat the patient
◉ Types of patients seen in E.R.. Answer: Abdominal pain
Chest pain
Breathing difficulties
Injuries (especially falls in older adults)
Headache
Fever
Pain (the most common symptom)
◉ Forensic nurse role. Answer: Are educated to obtain patients
histories; collect forensic evidence; and offer counseling and follow-
up care for victims of rape, child abuse, and domestic violence also
known as intimate partner violence (IPV). They recognize evidence
of abuse and when to intervene on the patient's behalf. May include
information about developing a safety plan or how to escape a
violent relationship. Forensic nurse examiners document injuries
and collect physical and photographic evidence. They may also
provide testimony in court as to what was observed during the
examination and information about the type of care provided.
◉ Emergent or class I (red tag) (immediate threat to life or limb).
Answer: Airway obstruction
shock
, Respiratory distress
Chest pain with diaphoresis
Stroke
Active hemorrhage
Unstable vital signs
◉ Urgent or class II (yellow tag) (major injuries that require
treatment) can wait a short time for care. Treatment within 30
minutes to 2 hours.. Answer: o Patient should be treated quickly but
immediate threat to life does not exist at the moment
Severe abdominal pain
Renal colic
Open fractures with distal pulse
Large wounds
Displaced or multiple fractures
Complex or multiple soft tissue injuries
New-onset respiratory infection, especially pneumonia in older
adults
◉ Nonurgent or class III (green tag) (walking wounded) (minor
injuries that do not require immediate treatment) delayed more
than 2 hours. Answer: Skin rash
Strains and sprains
