1. A nurse is triaging clients after a mass casualty incident.
Which client should receive immediate priority treatment?
A. A client with a sprained ankle and stable vital signs B. A client
with minor abrasions and emotional distress C. A client with severe
respiratory distress and cyanosis D. A client with a closed arm
fracture and moderate pain
Answer: C. A client with severe respiratory distress and cyanosis
Rationale: During disaster triage, airway and breathing problems
receive the highest priority because impaired oxygenation can quickly
become life-threatening. Severe respiratory distress and cyanosis
indicate inadequate oxygenation and require immediate intervention to
preserve life.
2. Which color tag is assigned to clients requiring immediate
treatment during disaster triage?
A. Green B. Yellow C. Black D. Red
Answer: D. Red
,Rationale: The red tag identifies clients with life-threatening
conditions who require immediate medical intervention. Examples
include severe bleeding, airway obstruction, and shock. Prompt
treatment can significantly improve survival outcomes.
3. A nurse is caring for a client exposed to a chemical spill. What
is the nurse’s first priority?
A. Start intravenous fluids B. Obtain a detailed health history C.
Ensure decontamination is completed D. Administer pain
medication
Answer: C. Ensure decontamination is completed
Rationale: Decontamination is essential to prevent continued exposure
and reduce contamination risks to healthcare workers, other clients,
and the environment. Stabilization measures can proceed safely after
contamination is controlled.
4. Which action is most appropriate when caring for a client with
suspected spinal cord injury after a motor vehicle accident?
A. Encourage the client to sit upright B. Maintain cervical spine
immobilization C. Place the client in Trendelenburg position D.
Allow the client to ambulate with assistance
Answer: B. Maintain cervical spine immobilization
Rationale: Cervical spine immobilization prevents further spinal cord
damage. Movement of the neck in clients with suspected spinal injury
can worsen neurological impairment or cause permanent paralysis.
5. A nurse in the emergency department is assessing a client with
signs of hypovolemic shock. Which finding should the nurse
expect?
, A. Bradycardia B. Warm, flushed skin C. Hypotension and
tachycardia D. Increased urine output
Answer: C. Hypotension and tachycardia
Rationale: Hypovolemic shock occurs when fluid loss decreases
circulating blood volume. The body compensates with tachycardia to
maintain cardiac output, while hypotension develops as fluid losses
worsen.
6. Which intervention is the priority when managing a client
experiencing anaphylactic shock?
A. Administer oral antihistamines B. Initiate seizure precautions C.
Administer intramuscular epinephrine D. Restrict oral fluids
Answer: C. Administer intramuscular epinephrine
Rationale: Epinephrine rapidly reverses airway swelling,
bronchoconstriction, and hypotension associated with anaphylaxis.
Immediate administration is critical to prevent respiratory collapse and
cardiovascular failure.
7. A nurse is preparing for disaster response. Which item is
considered part of personal protective equipment (PPE)?
A. Stethoscope B. Surgical mask C. Intravenous tubing D. Blood
pressure cuff
Answer: B. Surgical mask
Rationale: PPE protects healthcare workers from exposure to
infectious agents and hazardous substances. Surgical masks help
reduce transmission of respiratory pathogens during emergencies and
disasters.
