A 72-year-old patient with morbid obesity requires extensive exposure for an exploratory laparotomy. The patient has limited mobility, necessitating a large team for safe positioning. Which approach best balances safety and privacy?
- ALimit the positioning team to two members to reduce the number of staff viewing the patient.
- BUtilize bath blankets to cover uninvolved areas while coordinating the required staff for safe patient positioning.✓ Correct
- CExpose the entire torso upon room entry so the team can quickly assess the skin folds.
- DRequest the anesthesia provider to administer heavy sedation before transporting the patient into the operating room.
Why this is the answer
Patients with morbid obesity often require additional personnel to prevent positioning injuries, but this necessity does not negate their right to privacy. Using bath blankets to cover the patient while the team coordinates the move ensures that modesty is maintained without compromising physical safety. Option A is dangerous; limiting the team to two members for a morbidly obese patient risks severe injury to both the patient and the staff. Option C unnecessarily strips the patient of their dignity by exposing them prematurely before the actual prep begins. Option D is inappropriate because administering heavy sedation outside the OR solely to avoid the nursing intervention of managing privacy introduces unnecessary airway risks and falls outside the standard scope of privacy management.
🔑 Key TakeawayBalance physical safety with privacy by using blankets to cover uninvolved areas during multi-staff positioning.
During an open tracheostomy under local anesthesia with supplemental oxygen via face tent, the drape suddenly ignites when the electrosurgical pencil is activated.
- APour sterile saline directly onto the burning drape over the patient.
- BStop the flow of supplemental oxygen and remove the burning drape.✓ Correct
- CDischarge a carbon dioxide fire extinguisher directly onto the surgical field.
- DPat the burning surgical drape with a sterile wet surgical towel.
Why this is the answer
In the event of a drape fire on a patient, especially in an oxygen-enriched environment, the immediate actions are to stop the oxidizer by halting the oxygen flow and to remove the fuel by taking the burning drape off the patient. Pouring saline directly onto the drape while it is still on the patient can cause hot liquids to scald the skin and leaves the burning material in contact with the patient. Discharging a fire extinguisher is a secondary measure reserved for fires that cannot be controlled by drape removal. Patting the drape with a wet towel is dangerous because it fails to remove the heat source from the patient and can inadvertently spread the flames or cause thermal contact burns.
🔑 Key TakeawayFor an on-patient drape fire, immediately halt the oxygen flow and remove the burning material.
During the preparation of a multi-part robotic instrument for sterilization, the nurse notes that the manufacturer's instructions for use require specific disassembly. How should the nurse manage the instrument components for the sterilization cycle?
- AReassemble the components loosely to ensure all parts remain together during sterilization.
- BDisassemble the components completely and place them adjacent within the same tray.✓ Correct
- CKeep the components fully assembled to prevent mechanical damage during the process.
- DSeparate the components into different rigid containers to maximize sterilant surface contact.
Why this is the answer
Multi-part instruments must be disassembled according to the manufacturer's instructions to expose all surfaces to the sterilant. Placing them adjacent within the same tray ensures all parts are sterilized together and are easily accessible for reassembly at the sterile field. Option A and Option C are incorrect because leaving parts assembled, even loosely, traps bioburden and blocks sterilant from reaching internal mechanisms. Option D is incorrect because separating parts into different containers significantly increases the risk of losing critical components and complicates the surgical setup.
🔑 Key TakeawayMulti-part instruments must be completely disassembled per the manufacturer's instructions and kept together in the same tray.
An operating room is being prepared for a total joint arthroplasty. The circulating nurse checks the environmental monitor and notes the monitor shows fifteen total air changes per hour and neutral pressure relative to the adjacent sterile core. What is the most appropriate action?
- AProceed with the procedure since neutral pressure is acceptable here.
- BContinue preparation but ensure doors remain closed during the case.
- CDelay the procedure until positive pressure and twenty changes are met.✓ Correct
- DTransfer the procedure to an OR with negative pressure capabilities.
Why this is the answer
The operating room must maintain positive pressure relative to adjacent corridors and a minimum of twenty air changes per hour to effectively dilute and remove airborne contaminants. Neutral pressure and inadequate air changes significantly increase the risk of surgical site infections. Option C is correct because the environment is unsafe for a sterile procedure. Option A is incorrect because neutral pressure allows contaminants to enter the room. Option B is incorrect because keeping doors closed will not fix the baseline HVAC failure. Option D is incorrect because operating rooms require positive, not negative, pressure.
🔑 Key TakeawayOperating rooms require positive pressure and a minimum of twenty total air changes per hour.
