CNOR Patient Care and Safety Review (25%): Time-Outs, Counts, Positioning and OR Hazards
Patient Care and Safety is the largest CNOR area, 46 of 185 scored questions. Here is what CCI's outline lists, how it maps to the 2027 exam, and the intraoperative decisions it turns on: the time-out, count discrepancies, positioning against nerve injury, labeling on the sterile field and surgical smoke, with two original practice questions.
Short answer
Patient Care and Safety, area 3a, is the largest CNOR area: 25% of the exam, or 46 of the 185 scored questions, and the core of the 49-item Intraoperative Patient Care and Safety area planned for 2027. It covers what the perioperative nurse does from room setup to closing: the time-out, surgical counts, positioning against pressure and nerve injury, skin antisepsis, the sterile field, medication labeling, specimens and implants, and hazards such as fire, smoke and radiation. Its tasks are actions, so prepare to choose the safest next step under national standards and CCI's references, not local habit.
Area 3a carries more CNOR questions than any other area, and it is where daily habit can mislead you, because every OR has its own routines. This review stays with what CCI's outline lists and what public national sources say about it. It doesn't reproduce AORN's Guidelines for Perioperative Practice, which CCI names as a primary reference: use them, and the textbooks CCI lists, to check anything your facility does differently.
What CNOR area 3a covers, and where it goes in 2027
CCI's Task & Knowledge Statements list the tasks in Patient Care and Safety. Grouped by Passy for study:
| Group | Tasks CCI lists |
|---|---|
| Verification | Perform universal protocol (time-outs, pre-procedure identification and verification, site marking, post-procedure debrief); verify the correct implants are available and prepared |
| The sterile field and the site | Maintain a sterile field with aseptic technique; prepare the surgical site; identify wound classifications; maintain dressings, tubes, lines and drains |
| The patient | Perform proper positioning; provide comfort measures; protect dignity, privacy and rights; evaluate response to drugs such as pain management; assist with anesthesia management, including intubation, extubation, monitors and cricoid pressure; anticipate blood transfusion or salvage |
| Items and medications | Perform surgical counts; label solutions, medications and their containers; verify specimens are prepared, labeled and transported correctly; prepare explants for final disposition |
| Hazards and equipment | Monitor chemical, fire, smoke plume, radiation, electrical and laser hazards; select protective barriers such as lead aprons, goggles and laser shields; control noise, temperature, humidity and traffic; use equipment per the manufacturer; use proper body mechanics; intervene with disruptive behavior |
On the six-area exam CCI plans for 2027, most of this becomes Intraoperative Patient Care and Safety, with 49 scored items, according to CCI's job analysis page. Its knowledge statements keep counts, positioning, skin antisepsis, medication labeling, wound classification, surgical plume, fire and radiation. Universal protocol moves to the Individualized Plan of Care Development area. Studying these topics now serves either version. When you want volume, 425 planned Patient Care and Safety questions come with an explanation for every option.
The CNOR time-out: what the Joint Commission requires
The Joint Commission's Universal Protocol has three parts: a preprocedure verification, site marking and a time-out. Its 2026 requirements for ambulatory care still list them as standards, and for hospitals they now sit under National Performance Goal 1, "Right Patient, Right Care." For the time-out, the Joint Commission says:
- When: immediately before starting the invasive procedure or making the incision
- How: standardized by the organization and started by a designated member of the team
- Who: the immediate members of the procedure team, including the person doing the procedure, the anesthesia providers, the circulating nurse, the operating room technician and other active participants
- What, at a minimum: agreement on the correct patient identity, the correct site and the procedure to be done
- When to stop: "The procedure is not started until all questions or concerns are resolved"
- When to repeat: before each procedure when two or more are done on the same patient and the person performing them changes
- Record: documentation that the time-out was completed
Two related points are worth knowing. The Joint Commission's Sentinel Event Alert 68 asks that the time-out include a fire risk assessment, covered in the CNOR emergency situations review. And the WHO, whose Surgical Safety Checklist runs at three points (before induction, before skin incision and before the team leaves the OR), says in its safe surgery FAQ (2014, no longer updated) that one person should lead it, and that this "will often be a circulating nurse." Preprocedure verification and site marking are in the CNOR assessment and plan of care review.
Surgical counts and retained surgical items
"Perform appropriate surgical counts" is one task on CCI's list, but count scenarios turn on the reasoning behind it. AHRQ's patient safety network primer on retained surgical items makes points worth knowing:
- Counts are "heavily dependent on human performance and are thus subject to human error"
- In a review of 46 retained-sponge cases, the final sponge count was called "correct" in 40 of them. A count called correct when an item remains is the most common and most dangerous failure
- Barcode, radiofrequency and RFID systems are adjuncts that "must be used in addition to manual surgical sponge counts," not instead of them
- When a count can't be reconciled, teams take secondary actions such as repeating the wound exam, recounting, searching the room and taking x-rays, and an item can still be missed if an intraoperative image isn't read by a radiologist
A pattern consistent with AHRQ's primer: say the count is incorrect out loud, to the surgeon, as soon as you know; recount and search; don't record a count as correct that you haven't reconciled; and follow your facility's policy on imaging and documentation. When counts happen and which items are counted come from the references and facility policy: for this task, CCI's Study Plan points to AORN's guideline on retained surgical items and to chapters in Alexander's and Berry and Kohn's.
Positioning: pressure and nerve injury on the CNOR
CCI's knowledge statement is "principles of positioning including risk factors for pressure and nerve injury." Published reviews give the concrete risks, though the British Journal of Anaesthesia review notes that the recommendations rest on low-quality evidence:
- Ulnar nerve. A 2023 systematic review in the British Journal of Anaesthesia found postoperative ulnar neuropathy rare (about 1 in 14,733 anesthetics) and advises anatomically neutral arm positioning and padding. Forearm pronation "increases pressure within the ulnar groove," so a supine patient's forearm should be supinated or neutral; elbow flexion beyond 90 degrees may increase risk; and surfaces touching the ulnar groove should be padded with foam or gel, with no padding system shown to be better than another
- Brachial plexus. A 2026 review in Cureus describes the classic risk as marked shoulder abduction, often beyond 90 degrees, combined with external rotation, plus neck rotation or extension away from the arm. It recommends keeping the head and neck neutral
- Common fibular (peroneal) nerve. The same review names lithotomy as a classic scenario: the nerve can be compressed by leg holders or sustained lateral pressure at the knee, so pad the fibular head and avoid that pressure
- Long cases. Recheck arm boards and padding after major table adjustments or repositioning
A practical way to answer positioning questions: find the nerve or pressure point at risk in the position described, then pick the option that keeps the joint neutral and the pressure off it. For recall of those risks, 130 planned Patient Care and Safety flashcards are meant for quick review.
Medications and solutions on the sterile field
"Label solutions, medications, and medication containers" is a separate CNOR task. The Joint Commission's 2026 ambulatory standard (for hospitals, the Joint Commission says its National Patient Safety Goals are now part of its National Performance Goals) requires that, both on and off the sterile field:
- All medications, medication containers and other solutions are labeled, "even if there is only one medication being used." Containers include syringes, medicine cups and basins
- Labeling happens whenever a medication or solution is moved from its original packaging into another container, and as soon as it is prepared, unless it is immediately administered
- The label shows the name, strength, amount and diluent if not apparent from the container, and an expiration date or time when it won't be used within 24 hours or expires sooner
- Labels are verified verbally and visually by two qualified people whenever the person preparing the medication isn't the person giving it
Surgical smoke, fire and radiation in the OR
Smoke. NIOSH's page on controlling surgical smoke says the plume from lasers and electrosurgical units can contain toxic gases and vapors such as benzene, hydrogen cyanide and formaldehyde, bioaerosols, cellular material and viruses. Its recommendations: combine general room ventilation with local exhaust ventilation, because room ventilation "is not by itself sufficient"; keep the smoke evacuator or suction nozzle "within 2 inches of the surgical site"; use a HEPA or equivalent filter; and keep the evacuator on whenever particles are being produced.
Fire. Area 3a lists fire among the hazards to monitor, and skin preparation is part of it: the Joint Commission names failure to let alcohol-based preparations dry completely among the contributing factors in surgical fires. The full fire triangle is in the CNOR emergency situations review.
Radiation and lasers. CCI's task is to select procedure-specific barriers, such as lead aprons and drapes, eye goggles and laser shields. The details come from the references and your facility's radiation and laser safety programs.
Two original CNOR-style questions on patient care and safety
Written by Passy for this guide. They aren't CCI items and don't come from any exam.
Question 1: a count that doesn't match
During closure of a laparotomy, the circulating nurse's sponge count is one short. The surgeon says the earlier count was correct and asks to keep closing. What should the nurse do first?
- A. Record the count as correct, since the earlier count matched
- B. Tell the surgeon the count is incorrect and start a recount and search
- C. Let closure continue and arrange an x-ray in the recovery unit
- D. Complete an incident report after the patient leaves the room
Keyed answer: B. AHRQ's primer says a count called "correct" when an item remains is the most dangerous failure, and that an unreconciled count calls for actions such as repeating the wound exam, recounting and searching the room. A records a count that isn't correct. C delays the search until after the wound is closed. D documents the problem without resolving it. Your facility's policy sets the exact sequence, including when imaging is needed.
Question 2: arms on armboards
A patient is supine with both arms on padded armboards for a four-hour procedure. Which arm position best follows published advice for reducing pressure on the ulnar nerve?
- A. Forearm pronated, with the elbow flexed beyond 90 degrees
- B. Forearm supinated or neutral, with the elbow not flexed past 90 degrees
- C. Forearm pronated, palm down, with extra padding under the wrist
- D. Any forearm position, as long as a gel pad sits under the hand
Keyed answer: B. The BJA review's summary table says forearm pronation increases pressure in the ulnar groove, recommends a supinated or neutral forearm for a supine patient, and says elbow flexion beyond 90 degrees may increase risk. A and C both pronate the forearm, and A also flexes the elbow too far. D ignores position, and padding belongs where the ulnar groove meets a surface, at the elbow, not under the hand.
Explanations like these are the model for full prep: at launch, Fix It is planned to bring back every patient-safety question you miss until you get it right.
Studying CNOR area 3a with CCI's references
CCI's free Study Plan maps each 3a task to chapters in the textbooks it names and to specific AORN guidelines. A workable routine: for each task, write the one decision a question could turn on (for example, "what do I do when the count is off?"), check the answer in the reference the Study Plan names, and note where your unit does it differently. The CNOR study plan guide shows how much time this area deserves, about a quarter of your hours.
