Which principle guides the placement of instruments on the sterile back table?
Answer: Items are arranged in order of use with frequently used items closest to the scrub person
Organizing instruments by order of use and placing frequently needed items closest to the scrub person promotes efficiency and reduces breaks in sterile technique.
What is the function of the electrosurgical dispersive electrode (grounding pad)?
Answer: To provide a large surface area for the return of current to the ESU unit, preventing burns
The dispersive electrode spreads the returning current over a large body surface area, reducing current density and preventing burns at the return site.
Which patient population is at highest risk for latex allergy in the perioperative setting?
Answer: Patients with multiple previous surgeries, spina bifida, or healthcare worker history
Repeated latex exposure through surgeries, spina bifida management, or occupational contact significantly increases sensitization risk.
After a surgical sponge count discrepancy is identified at wound closure, what is the FIRST action the perioperative nurse should take?
Answer: Recount all sponges thoroughly with the scrub person
Recounting all sponges is the first step when a discrepancy is identified, followed by a search of the surgical field, and then imaging if still unresolved.
Which sterilization method is preferred for heat-sensitive surgical instruments such as endoscopes?
Answer: Ethylene oxide (EtO) or hydrogen peroxide plasma sterilization
Low-temperature sterilization methods such as ethylene oxide and hydrogen peroxide gas plasma are used for heat- and moisture-sensitive items like flexible endoscopes.
The anesthesia provider announces the patient has a difficult airway. Which piece of equipment should the perioperative nurse ensure is immediately available?
Answer: Video laryngoscope and surgical airway kit
A video laryngoscope improves visualization of a difficult airway, and a surgical airway kit allows emergency cricothyrotomy if intubation fails.
What does the acronym 'STSR' stand for in the perioperative setting?
Answer: Surgical Technologist in Scrub Role
STSR stands for Surgical Technologist in Scrub Role, referring to the allied health professional who serves as the primary scrub person during surgery.
