CHSE Simulation Operations 3 — Questions and Answers
Question 1: Which of the following BEST describes 'physical fidelity' in simulation?
- The degree to which the scenario matches real clinical decision-making complexity
- The extent to which the simulator looks, feels, and responds like the real clinical environment (Correct answer)
- The psychological immersion experienced by the learner during the scenario
- The accuracy of the manikin's vital sign responses to pharmacological interventions
Correct answer: The extent to which the simulator looks, feels, and responds like the real clinical environment
Physical fidelity refers to the realistic appearance and tactile properties of the simulator and its environment, distinct from conceptual or psychological fidelity.
Question 2: A simulation operations team is preparing a supply tray for a central line insertion scenario. Which principle should guide supply selection?
- Use expired but otherwise intact supplies to reduce cost
- Include only supplies that will be used, mirroring the clinical setting's standard kit (Correct answer)
- Provide every possible supply to allow learner improvisation
- Label all supplies clearly so learners know exactly what to use next
Correct answer: Include only supplies that will be used, mirroring the clinical setting's standard kit
Authentic supply kits that mirror the clinical environment reinforce correct procedural habits and prevent learners from developing workarounds unique to simulation.
Question 3: What is the PRIMARY role of a confederate in a simulation scenario?
- Operating the manikin's physiological parameters from the control room
- Playing a scripted role to provide cues and advance the scenario as planned (Correct answer)
- Evaluating and documenting learner performance on a checklist
- Serving as a backup facilitator if the primary facilitator becomes unavailable
Correct answer: Playing a scripted role to provide cues and advance the scenario as planned
Confederates are trained actors or staff who portray roles (family member, nurse, etc.) and deliver scripted cues that guide the scenario toward its learning objectives.
Question 4: Which environmental cue is MOST effective for increasing the realism of a mass casualty simulation?
- Increasing the number of high-fidelity manikins to 20 or more
- Incorporating realistic sounds, smells, and visual chaos consistent with a disaster scene (Correct answer)
- Using full personal protective equipment for all participating learners
- Streaming a live news broadcast about a disaster on monitors in the lab
Correct answer: Incorporating realistic sounds, smells, and visual chaos consistent with a disaster scene
Multi-sensory environmental cues (sound, smell, visual stimuli) have the greatest impact on psychological fidelity and learner immersion during mass casualty simulations.
Question 5: Before a simulation session involving medication administration, the operations team should:
- Replace all real medications with identical-appearing placebos and label them clearly as simulation medications (Correct answer)
- Remove all medication labels so learners must identify drugs by appearance
- Use actual controlled substances to maximize realism
- Allow learners to bring medications from their clinical units for the scenario
Correct answer: Replace all real medications with identical-appearing placebos and label them clearly as simulation medications
Simulation-labeled placebo medications protect against accidental administration of real drugs while preserving the fidelity of medication identification and administration steps.
Question 6: Which approach BEST manages 'simulator sickness' reported by learners using screen-based virtual simulation platforms?
- Increasing screen resolution to the highest available setting
- Shortening session duration, scheduling breaks, and optimizing frame rates (Correct answer)
- Encouraging learners to close their eyes during rapid motion sequences
- Switching all learners to high-fidelity manikin simulation instead
Correct answer: Shortening session duration, scheduling breaks, and optimizing frame rates
Shorter exposure times, adequate breaks, and smooth high frame-rate rendering reduce the vestibular-visual conflict that causes simulator sickness.
Question 7: When designing a simulation scenario for a mixed-experience group of learners, the operations setup should:
- Maximize scenario complexity to challenge the most experienced learners
- Allow the scenario parameters to be adjustable in real time to match group performance (Correct answer)
- Standardize the scenario at the novice level to avoid frustrating beginners
- Run separate scenarios sequentially for each experience level within the session
Correct answer: Allow the scenario parameters to be adjustable in real time to match group performance
Real-time adjustable parameters allow the operator to modulate difficulty so the scenario remains educationally appropriate for the actual learner performance observed.
