CHSE Simulation Fidelity

Question 1

A simulation educator uses a full-body manikin with realistic skin texture, integrated IV arm with flashback, and authentic defibrillator pads connected to a real AED. This PRIMARILY enhances which dimension of fidelity?

Accepted Answer

Physical fidelity

Answer

Physical fidelity refers to the degree to which the simulation's physical properties — the manikin, equipment, props, and tactile characteristics — resemble the real clinical situation. Using authentic equipment and realistic physical features directly increases physical fidelity.

Question 2

Psychological fidelity in simulation is BEST described as:

Accepted Answer

The degree to which the simulation engages learners cognitively and emotionally as they would be engaged in a real clinical situation

Answer

Psychological fidelity refers to how well the simulation engages the learner's psychological processes — decision-making under pressure, stress responses, emotional engagement, and cognitive load — mirroring the mental experience of real clinical care. It can be high even with low-tech equipment if the scenario feels real to the learner.

Question 3

A simulation educator creates a scenario in a room designed to replicate an emergency department, complete with appropriate bed layout, overhead lighting, ambient noise, an actual crash cart, and realistic signage. This PRIMARILY addresses which dimension of fidelity?

Accepted Answer

Environmental fidelity

Answer

Environmental fidelity refers to how closely the simulation setting replicates the actual clinical environment — including spatial layout, ambient sounds, equipment placement, and contextual cues. Creating a room that looks and feels like a real ED specifically targets environmental fidelity.

Question 4

Evidence regarding simulation fidelity and learning outcomes MOST consistently suggests that:

Accepted Answer

The appropriate fidelity level must be matched to learning objectives and learner experience level, as higher fidelity does not always improve outcomes

Answer

Research consistently shows that higher fidelity does not automatically lead to better learning. The optimal fidelity level depends on what is being taught, the learner's experience level, and the specific objectives. Novices sometimes perform better with lower fidelity that reduces extraneous cognitive load.

Question 5

A novice nursing student is learning urinary catheter insertion for the first time. Which simulation approach is MOST appropriate at this stage of learning?

Accepted Answer

A low-fidelity task trainer designed specifically for catheter insertion practice

Answer

For initial procedural skill acquisition, a focused low-fidelity task trainer targeting the specific skill is often most effective. High-fidelity simulation adds scenario complexity that can distract novices from mastering the procedural steps. Task trainers allow deliberate, repetitive practice of the core skill without extraneous cognitive demands.
