During the medical forensic exam, which guidance regarding physical actions is correct?

• A. The vic should urinate to clear the bladder for analysis
• B. The vic should change clothes to avoid contamination
• C. The vic should avoid urinating or defecating to preserve evidence, while basic needs are prioritized
• D. The vic should fast for 12 hours before the exam

Answer: (C)

Preserving evidence during a forensic medical exam means avoiding actions that could contaminate or destroy physical traces, while still addressing the survivor’s health and basic needs. Urinating or defecating can wash away or contaminate evidence such as bodily fluids or materials collected for DNA analysis, so guidance emphasizes avoiding those actions to protect potential evidence. At the same time, basic needs and medical care must be prioritized, so the person should not be left without support or medical relief. Changing clothes can alter or remove evidence on fabric or skin, which is why it’s not advised if the goal is to preserve evidence. Fasting before the exam isn’t a standard requirement and could cause needless discomfort or delay care.
