General Surgery Board Review Technology & Digital Applications 3

Question 1

What does 'digital twin' technology refer to in a surgical context?

Accepted Answer

A virtual physiologic replica of a patient used for preoperative simulation

Answer

A digital twin is a patient-specific virtual model built from imaging and physiology data, enabling surgeons to rehearse procedures before operating on the actual patient.

Question 2

Which standard governs the interoperability of medical devices and health information systems, enabling different platforms to exchange patient data?

Accepted Answer

HL7 FHIR

Answer

HL7 FHIR (Fast Healthcare Interoperability Resources) is the modern standard enabling real-time data exchange between EHRs, devices, and applications.

Question 3

During robotic-assisted surgery, 'instrument wristing' refers to which capability that conventional laparoscopy lacks?

Accepted Answer

Seven degrees of freedom articulation mimicking the human wrist

Answer

Robotic instruments articulate with seven degrees of freedom, including wrist-like rotation, overcoming the fixed-pivot constraint of straight laparoscopic instruments.

Question 4

What is 'natural language processing' (NLP) primarily used for in surgical informatics applications?

Accepted Answer

Extracting structured clinical data from free-text operative notes and records

Answer

NLP algorithms parse unstructured clinical text to extract diagnoses, procedures, and outcomes for research, quality improvement, and registry population.

Question 5

Which principle of radiation safety is represented by the acronym ALARA?

Accepted Answer

As Low As Reasonably Achievable

Answer

ALARA (As Low As Reasonably Achievable) mandates minimizing ionizing radiation exposure through time, distance, and shielding strategies.
