"Susan is a paramedic for the county ambulance service. Yesterday there was a terrible accident on the interstate when a bus carrying senior citizens to an Atlantic City casino was struck by a small dump truck as the truck tried to change lanes. Fifteen of the bus riders were killed and 25 injured. As Susan arrived on the scene to perform triage on the accident victims, she quickly made decisions as to which victims needed immediate care and who could wait. Susan was using what decision-making model in making these stressful decisions?"

Intuitive decision-making model

Explanation:

Intuitive decision-making model is a type of decision making model which is based on intuition. The other name for this decision-making model is 'sixth sense.' Intuitive decision-making model can be defined as a decision made on the basis of instinct or feelings without any proof for such decisions.

In the given scenario, Susan is making decision based on 'intutive decision-making model.' By observing the victims, she is making decisions based on her sixth sense of which patient need immediate care and which patient can hold on more.

Thus the correct answer is 'intuitive decision-making model.'
