Explanation: Fidelity refers to how closely a simulation reproduces the appearance and behavior of the real system or clinical environment. Higher fidelity means greater realism across physical, conceptual, and psychological dimensions. It is not defined by cost, duration, or group size.

Explanation: A standardized patient is a person carefully coached to portray an actual patient's history, body language, and emotional responses in a consistent and reproducible manner across encounters. SPs are especially valuable for communication, history-taking, and physical exam skills. They are human actors, not manikins or software.

Explanation: Task trainers (also called part-task trainers) replicate a specific anatomical region or system to allow repetitive practice of a single discrete skill, such as venipuncture, suturing, or airway management. They are not designed to recreate the full clinical context needed for team or ethics-based learning.

Explanation: In situ simulation takes place in the real clinical setting (e.g., an actual emergency department or operating room) using the real team and equipment. It is valuable for testing systems, identifying latent safety threats, and training in context. It is defined by location, not modality.

Explanation: Psychological fidelity is the degree to which the simulation evokes the same emotional and cognitive responses the learner would experience in the real situation, driving engagement and the willingness to behave authentically. Physical fidelity concerns the look and feel of equipment and environment, while conceptual fidelity concerns whether elements relate to one another in a realistic way.

Explanation: Conceptual fidelity means all elements of the scenario relate to one another in a way that makes clinical sense, for example, the lab values, vital signs, and physical findings all align with the intended diagnosis. If a patient is supposed to be in septic shock but the blood pressure is normal, conceptual fidelity is broken.

Explanation: Standardized patient encounters provide a realistic human interaction that allows learners to practice and be assessed on communication, empathy, history-taking, and difficult conversations such as breaking bad news. Manikins and task trainers cannot reproduce nuanced human verbal and nonverbal responses as effectively.

Explanation: Hybrid simulation blends modalities, most commonly pairing a standardized patient with a task trainer (such as a wearable suture pad or a pelvic model) so learners can both communicate with a real person and perform a procedure. This preserves both psychological fidelity and procedural realism.

Explanation: Screen-based (virtual) simulation presents clinical scenarios on a computer or device where learners interact through decisions, navigation, and responses. It scales well and allows asynchronous practice but lacks tactile, hands-on procedural realism.

Explanation: Moulage is the use of makeup, molds, and props to simulate injuries, rashes, diaphoresis, or other physical findings on a manikin or standardized patient. It enhances physical and psychological fidelity by providing realistic visual and tactile cues that drive clinical reasoning.
