Which sterilization method is considered the gold standard for heat-stable surgical instruments?
Answer: Steam autoclave (moist heat) sterilization
Steam autoclave (moist heat) sterilization is the gold standard for heat-stable instruments due to its reliability, speed, and non-toxic nature.
What does the Spaulding Classification system categorize?
Answer: Medical devices by infection risk to determine required reprocessing level
The Spaulding Classification categorizes medical devices into critical, semi-critical, and non-critical items based on their infection risk and the required level of disinfection or sterilization.
In the perioperative setting, the 'scrub' role is responsible for:
Answer: Managing the sterile field and passing instruments to the surgeon
The scrub person works within the sterile field, maintaining sterility and passing instruments, sutures, and supplies to the surgeon.
Malignant hyperthermia (MH) is triggered by which class of agents?
Answer: Volatile inhalation anesthetics and succinylcholine
Malignant hyperthermia is triggered by volatile halogenated inhalation anesthetics (e.g., sevoflurane, desflurane) and the depolarizing muscle relaxant succinylcholine.
The first-line pharmacologic treatment for malignant hyperthermia crisis is:
Answer: Dantrolene sodium
Dantrolene sodium is the specific antidote for malignant hyperthermia, acting by inhibiting calcium release from the sarcoplasmic reticulum in muscle cells.
Which principle of surgical asepsis states that sterile items placed below the patient's waist level are considered contaminated?
Answer: Sterile tables are sterile only at table level
A fundamental aseptic principle is that the sterile drape is only considered sterile at table level; anything that falls or is lowered below this level is contaminated.
What is the recommended OR temperature range to reduce surgical site infections and prevent patient hypothermia?
Answer: 68–75°F (20–24°C)
AORN guidelines recommend OR temperatures of 68–75°F (20–24°C) to balance infection control and normothermia maintenance for most adult procedures.
