CFN Forensic Evidence Collection & Documentation 4

Question 1

A forensic nurse is examining a child for suspected physical abuse. She notes patterned bruising on the buttocks. The best initial documentation action is:

Accepted Answer

Photograph the injury with scale and label, then complete a detailed body diagram

Answer

Photographic documentation with proper scale and labeling combined with anatomical body diagram mapping is the priority forensic documentation step before interviews or reporting.

Question 2

When documenting a patient's account of an assault for forensic purposes, the nurse should:

Accepted Answer

Record the patient's exact words in quotation marks

Answer

Direct quotes from the patient are documented verbatim in forensic records because they may be admissible as statements and preserve the patient's own narrative.

Question 3

A forensic nurse collects a reference buccal swab from a consenting patient. The purpose of this swab is to:

Accepted Answer

Provide the patient's own DNA profile to compare against other collected specimens

Answer

Reference buccal swabs establish the victim's known DNA profile so laboratories can differentiate the victim's own DNA from potential perpetrator DNA in collected specimens.

Question 4

Which factor most significantly affects the reliability of injury aging (estimating when a bruise occurred) in forensic documentation?

Accepted Answer

Variation in skin tone, depth, and individual healing response

Answer

Bruise color progression varies widely based on skin tone, depth of injury, vascular supply, and individual physiology, making precise age estimation unreliable.

Question 5

A suspected drug-facilitated sexual assault (DFSA) patient presents 10 hours after the assault. Which urine collection timing consideration is most important?

Accepted Answer

Urine should be collected immediately as many drugs and metabolites remain detectable for 72–96 hours

Answer

Many DFSA drugs and their metabolites remain detectable in urine for 72–96 hours, so immediate urine collection at presentation is critical regardless of time elapsed.
