CHSE Simulation Fidelity — Questions and Answers
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?
- Psychological fidelity
- Conceptual fidelity
- Physical fidelity (Correct answer)
- Environmental fidelity
Correct answer: Physical fidelity
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:
- The accuracy of the manikin's automated physiological responses such as lung sounds and pupil dilation
- The degree to which the simulation engages learners cognitively and emotionally as they would be engaged in a real clinical situation (Correct answer)
- The physical replication of a clinical environment including furniture, lighting, and equipment layout
- The technical sophistication and processing capability of the simulation system software
Correct answer: The degree to which the simulation engages learners cognitively and emotionally as they would be engaged in a real clinical situation
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?
- Physical fidelity
- Psychological fidelity
- Functional fidelity
- Environmental fidelity (Correct answer)
Correct answer: Environmental fidelity
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:
- Higher physical fidelity always produces superior learning outcomes and should always be maximized
- Lower fidelity is always preferable because it reduces cognitive overload for all learner types
- The appropriate fidelity level must be matched to learning objectives and learner experience level, as higher fidelity does not always improve outcomes (Correct answer)
- Fidelity only matters for procedural skill training and has no impact on team-based simulation outcomes
Correct answer: The appropriate fidelity level must be matched to learning objectives and learner experience level, as higher fidelity does not always improve outcomes
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?
- High-fidelity, full-body manikin with realistic physiological responses to maximize engagement
- A low-fidelity task trainer designed specifically for catheter insertion practice (Correct answer)
- An interprofessional scenario with a standardized patient portraying a complex UTI case
- A high-fidelity virtual reality simulation with haptic force feedback
Correct answer: A low-fidelity task trainer designed specifically for catheter insertion practice
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.
Question 6: 'Functional fidelity' in simulation MOST accurately refers to:
- The operational efficiency of a simulation center's scheduling and resource management systems
- The financial cost of maintaining simulation equipment in full working condition
- The degree to which the simulation replicates the functions and actions required in the real task, regardless of physical appearance (Correct answer)
- A manikin's ability to simultaneously perform all physiological functions such as breathing, pulse, and pupil response
Correct answer: The degree to which the simulation replicates the functions and actions required in the real task, regardless of physical appearance
Functional fidelity is about whether the simulation requires learners to perform the same actions, decisions, and functions as the real task — not how realistic it looks. A simple part-task trainer can have high functional fidelity for a specific skill even if it looks nothing like a human body.
