Which electrosurgical unit (ESU) mode uses alternating current to simultaneously cut and coagulate tissue?
Answer: Blend mode
Blend mode combines cutting and coagulation by interrupting the current cycle, producing both a cutting effect and hemostasis simultaneously.
When preparing a patient for a total hip arthroplasty in the lateral position, which padding is ESSENTIAL to prevent a common positioning injury?
Answer: Axillary roll placed below the axilla
An axillary roll placed just below (not in) the axilla protects the brachial plexus and neurovascular structures of the dependent arm.

A surgeon requests the Trendelenburg position for a pelvic laparoscopy. Which physiological effect should the perioperative nurse anticipate?
Answer: Cephalad shift of the diaphragm
Trendelenburg causes abdominal viscera and the diaphragm to shift cephalad, reducing lung compliance and functional residual capacity.
Which Spaulding classification applies to a rigid sigmoidoscope that contacts intact mucous membranes but does not penetrate sterile tissue?
Answer: Semi-critical — requires high-level disinfection
Semi-critical items contact intact mucous membranes and require high-level disinfection as a minimum standard of reprocessing.
During a laparoscopic cholecystectomy, the surgeon reports difficulty visualizing the operative field. The circulating nurse notes the CO2 insufflation pressure is 25 mmHg. What is the standard maximum safe intraabdominal pressure?
Answer: 15 mmHg
The standard safe intraabdominal insufflation pressure for laparoscopy is 15 mmHg; higher pressures increase the risk of cardiovascular and respiratory compromise.
