Q

Triage

A
  • The sorting of patients to determine priority health care needs and the proper site of treatment
  • In nondisaster situations, health care workers assign highest priority and allocate most resources to the most critically ill patients.
  • In disaster situations with large numbers of casualties, decisions are based on the likelihood of survival and the consumption of resources.
  • North Atlantic Treaty Organization (NATO) triage system
  • Red, yellow, green and black (Table 73-1)
17
Q

Triage Considerations

A
  • Managing internal problems
  • Communicating with the media and family
  • Managing media requests for information
  • Caring for families
  • Stress management
18
Q

Triage Considerations: The Nurse’s Role

A
  • Nurse’s role varies during disaster
  • May be asked to perform duties outside of expertise: intubate, insert chest tube, suture
  • May serve as triage officer
  • Nurses must strive to maximize patient safety
  • Be aware of state regulation
19
Q

Triage Considerations: Ethical Conflicts

A
  • Assisted suicide
  • Confidentiality
  • Consent
  • Duty
  • Futile therapy
  • Rationing care
  • Resuscitation
20
Q

Triage Considerations: Managing Behavioral Issues

A
  • Anxiety
  • Depression
  • Impaired performance
  • Interpersonal conflicts
  • Posttraumatic stress disorder
  • Somatization (fatigue, general malaise, headaches, gastrointestinal disturbances, skin rashes)
  • Substance abuse
21
Q

Question #2
What is the name for the triage category in which injuries are significant and require medical care but can wait hours without threat to life or limb?
- A. Delayed
- B. Expectant
- C. Immediate
- D. Minimal

A

A.
- Delayed Delayed injuries are significant and require medical care but can wait hours without threat to life or limb. Expectant injuries are extensive, and chances of survival are unlikely even with definitive care. Immediate injuries are life threatening but survivable with minimal intervention. Minimal injuries are minor, and treatment can be delayed hours to days.

22
Q

Personal Protective Equipment

A
  • Purpose: to shield the health care provider from chemical, physical, biological, and radiological hazards that may exist when caring for contaminated patients
  • Categories of protective equipment
    — Level A: self-contained breathing apparatus (SCBA) and vapor-tight chemical resistant suit, gloves, and boots
    — Level B: high level of respiratory protection (SCBA) but lesser skin and eye protection; chemical-resistant suit
    — Level C: air-purified respirator, coverall with splash hood, chemical-resistant gloves and boots
  • Level D: typical work uniform
23
Q

Question #3
What is level A protective equipment?

A
  • A. Self-contained breathing apparatus (SCBA) and vapor-tight chemical resistant suit, gloves, and boots
  • B. High level of respiratory protection (SCBA) but lesser skin and eye protection; chemical-resistant suit
  • C. Air-purified respirator, coverall with splash hood, chemical-resistant gloves and boots
  • D. Typical work uniform
    A?
24
Q

Common Biological Weapons: Smallpox

A

Smallpox
- Virus, Incubation 12 days
- Extremely contagious; spread by direct contact, by contact with clothing or linens, Or by droplets person-to-person
- Manifestations: High fever, malaise, headache, backache, and prostration; after 1 to 2 days a maculopapular rash appears on the face, mouth, pharynx, and forearms
- Treatment is supportive care with antibiotics for any additional infection

25
Q

Chemical Weapons

A
  • Effects are more apparent and occur more quickly than those caused by biologic weapons. (Table 73.6)
  • Agents vary in
    — Volatility
    — Persistence
    — Toxicity
    — Latency
    — Limiting exposure
  • Limitation of exposure is essential with evacuation and decontamination as soon possible and as close to the scene of the incident as possible
26
Q

Types of Chemical Agents

A
  • Vesicants
  • Nerve agents
  • Blood agents
  • Pulmonary agents
27
Q

Vesicants

A
  • Lewisite, sulfur mustard, nitrogen mustard, phosgene
  • Cause blistering and burning
  • Respiratory effects can be serious and cause death
  • Decontamination with soap and water; do not scrub or use hypochlorite solutions
  • Eye exposure requires copious irrigation
  • Treatment for lewisite exposure: dimercaprol IV or topically
28
Q

Nerve Agents

A
  • Sarin, soman, tabun, organophosphates, and VX
  • Inhibit cholinesterase, causing cholinergic symptoms progressing to loss of consciousness, seizures, copious secretions, apnea, and death
  • Treatment: supportive care, atropine, benzodiazepine and pralidoxime
  • Decontaminate with copious amounts of soap and water or saline for at least 20 minutes
  • Blot; do not wipe off
  • Plastic equipment will absorb sarin gas
29
Q

Pulmonary Agents

A
  • Phosgene and Chlorine: both vaporize rapidly causing pulmonary injury
  • Destroy the pulmonary membrane that separates the alveolus from the capillary bed, disrupting alveolar–capillary oxygen transport mechanisms. Capillary leakage results in fluid-filled alveoli
  • Manifestations include pulmonary edema with shortness of breath, especially during exertion. An initial hacking cough is followed by frothy sputum production
30
Q

Radiation Exposure

A
  • Radiation exposure may occur because of nuclear weapon, nuclear reactor incidents, or exposure to radioactive samples
  • Exposure to radiation is affected by time distance and shielding
  • Types of radiation-induced injury
    — External irradiation: all or part of the body is exposed to radiation; decontamination is not necessary; not a medical emergency
    — Contamination: exposure to radioactive gases, liquids, or solids; requires immediate medical management to prevent incorporation
    — Incorporation: uptake of the radioactive material into the body
31
Q

Radiation Decontamination #1

A
  • Triage outside the hospital
  • Cover floor and use strict isolation precautions to prevent the tracking of contaminants
  • Air ducts and vent are sealed
  • Waste is double bagged and labeled “radiation waste”
  • Staff protection
    — Water-resistant gowns, two pairs of gloves, caps, goggles, masks, and booties
    — Dosimetry devices
32
Q

Radiation Decontamination #2

A
  • Patients are surveyed for radiation and directed to the decontamination area
  • Decontaminate each patient outside the ED with a shower
  • Water, tarps, towels, soap, gowns, all patient belongings, and so on must be collected and contained
  • Patients are resurveyed and reshowered as necessary
  • Showering should be performed to not contaminate clean areas with runoff from the showering
  • Biologic samples: nasal and throat swabs, blood
  • Internal contamination requires additional treatment—catharsis and gastric lavage with chelating agents
33
Q

Acute Radiation Syndrome

A
  • Acute radiation syndrome (ARS): dose of radiation determines if ARS will develop
  • All body systems are affected by ARS
  • Presenting signs and symptoms determine predicted survival
  • Probable survivors have no initial symptoms or only minimal symptoms
  • Possible survivors present with nausea and vomiting that persists for 24 to 48 hours
  • Improbable survivors are acutely ill with nausea, vomiting, diarrhea, and shock. Neurologic symptoms suggest a lethal dose
