You are in a mixed acute paediatric setting. The examiner will move you through capture technique, storage governance, and court-statement preparation. [3] [10]
Branch 1 — Capture technique
Examiner: A 5-month-old not yet rolling is found to have a 1.5 cm bruise behind the ear. Describe exactly how you photograph it. [3]
Strong answer: Photograph before any cleaning, dressing, or procedure. Capture the three-shot set: an orientation shot placing the bruise in anatomical context behind the ear, a mid-range shot of the bruise against landmarks, and a close-up with a scale held in the same plane as the injury, camera perpendicular to the skin at ninety degrees to avoid distortion. Good lighting, repeat blurred images. Transcribe onto a body map with site, colour, shape, and two-dimensional measurement, and record the non-mobile developmental status in the note. [3]
Examiner: Why the scale and the perpendicular angle? [3]
Strong answer: A close-up without a scale is dimensionless — the court cannot infer size or compare it to an alleged implement. An oblique angle distorts apparent size and shape. The in-plane scale and perpendicular capture are geometrically necessary for an interpretable image; they are what make the close-up evidence rather than a picture. [3]
Branch 2 — Storage and governance
Examiner: Where do the images go, and what is unacceptable? [1] [9]
Strong answer: Into the secure clinical imaging system or designated child-protection record, access-controlled and audit-logged, labelled with identity, date, time, and site. Personal-phone or messaging-app storage is unacceptable: the image lives outside the controlled record, access is unlogged, retention unmanaged, and integrity open to challenge; it may breach professional and privacy standards. Chain of custody means who accessed the images and when is recoverable. [1] [9]
Examiner: A junior tells you they snapped it on their phone for speed. What do you do? [1]
Strong answer: Transfer the image to the secure record immediately if the local policy permits, document what happened, and use it as a teaching moment about the protocol. Personal-device capture undermines integrity and professional conduct; the protocol exists precisely because improvisation fails under pressure. [1] [3]
Branch 3 — Fact versus opinion
Examiner: Draft the key sentence of the written record. How do you separate fact from opinion? [10]
Strong answer: State the observed findings as fact: a 1.5 cm bruise behind the left ear, ovoid, purple, non-blanching, in a non-mobile infant. Record the caregiver's mechanism verbatim as their account. Then, labelled as opinion: the location is a high-specificity site and the mechanism is developmentally implausible for an infant not yet rolling. Causation is interpretation, so it is opinion with reasoning, never stated as observed fact. [10] [6]
Branch 4 — The court statement
Examiner: You are asked for a statement six weeks later. How do you prepare it? [10]
Strong answer: Return to the record, not memory. Identify the child and encounter; state findings as fact; quote the mechanism verbatim; label any opinion explicitly with reasoning; disclose uncertainty and the limits of the assessment; stay within competence. Do not overstate certainty. You are a witness to fact, not the investigator and not the decision-maker. [10] [6]
Branch 5 — Quality improvement
Examiner: How do you stop this failing again? [2]
Strong answer: Embed the standardised protocol and remote peer review. The peer-review quality-improvement evidence shows that structured feedback against a standard raises completeness and quality over time. Review significant findings with a colleague before finalising the record, because a second observer catches omissions and improves interpretation. [2] [4]
Examiner extras
- The photograph is the first clinical action after the safety survey, before any procedure. [3]
- Colposcopic photography in sexual-abuse assessment supports reliable peer review and protects the child from repeat examination. [4]
- Document chain of custody for every forensic specimen at every transfer. [8]
- Telemedicine extends specialist review but the capture standard does not drop for a remote reviewer. [3]
