Instrument Inspection Flashcards

What is the purpose of using a magnifying glass or lighted magnification during instrument inspection?

Answer: To detect minute cracks, pitting, burrs, and residual soil invisible to the naked eye

Magnification reveals microscopic defects and residual contamination that could compromise instrument function or patient safety if undetected.

How should box locks on hemostatic forceps be tested during inspection?

Answer: By opening and closing to verify smooth operation and secure ratchet engagement at each position

Box locks should be tested by cycling through all ratchet positions to ensure smooth movement and secure locking, which is critical for maintaining hemostasis during surgery.

What visual indicator suggests an instrument has been exposed to a harsh chemical or improper cleaning process?

Answer: Unusual staining, discoloration, or a rainbow-like appearance on the surface

Staining, discoloration, or rainbow patterns on stainless steel instruments indicate chemical damage from improper cleaning agents, hard water deposits, or incompatible solutions.

Why must insulated electrosurgical instruments be tested for current leakage before reuse?

Answer: To prevent unintended burns to the patient or surgical team from compromised insulation

Damaged insulation on electrosurgical instruments can cause current leakage, resulting in unintended burns to patients or surgical team members.

What is the correct action when an instrument is found to have a broken tip during inspection?

Answer: Remove from service, tag for repair, and check if the broken piece was recovered from the surgical site

A broken instrument tip is a critical safety issue — the fragment must be accounted for to ensure it wasn't retained in a patient, and the instrument must be removed from service.

What does the term 'passivation' refer to in instrument maintenance?

Answer: The formation of a protective chromium oxide layer on stainless steel that resists corrosion

Passivation is the chemical process that creates a protective chromium oxide layer on stainless steel, shielding it from corrosion and extending instrument life.
