Question 1

In the JumpSTART pediatric triage system, what additional step is performed for a non-breathing child that differs from adult START triage?

Accepted Answer

Five rescue breaths before classifying as Expectant

Answer

JumpSTART includes five rescue breaths for apneic children with a palpable pulse, recognizing that pediatric cardiac arrest is more commonly respiratory in origin and potentially reversible with ventilation.

Question 2

A hospital is preparing for a surge of 200 patients from a mass casualty incident. Which strategy best manages this surge capacity?

Accepted Answer

Activating discharge protocols, opening auxiliary treatment spaces, and calling in off-duty staff

Answer

Surge capacity management requires a multi-pronged approach: rapidly discharging stable inpatients, opening overflow treatment areas, and activating callback systems for additional staff.

Question 3

Which type of disaster agent causes delayed symptom onset of hours to days, making initial triage particularly challenging?

Accepted Answer

Biological agents such as anthrax

Answer

Biological agents often have incubation periods of hours to days, meaning exposed individuals may appear asymptomatic during initial triage and present later with severe illness.

Question 4

After a building collapse, a trapped patient is extricated after 6 hours of limb compression. The nurse should anticipate which life-threatening complication upon release?

Accepted Answer

Crush syndrome with hyperkalemia and acute renal failure

Answer

Crush syndrome occurs when prolonged compression causes rhabdomyolysis, releasing myoglobin, potassium, and other toxic metabolites into the circulation upon reperfusion, leading to hyperkalemia, cardiac dysrhythmias, and acute renal failure.

Question 5

The concept of 'reverse triage' in disaster management refers to:

Accepted Answer

Discharging current inpatients to create capacity for incoming casualties

Answer

Reverse triage involves evaluating current hospital inpatients and rapidly discharging those who can safely leave to free beds, staff, and resources for incoming disaster casualties.
