Certified Registered Nurse First Assistant (CRNFA) — Questions and Answers
Question 1: Which phase of wound healing is characterized by fibroblast proliferation and collagen deposition?
- Maturation/remodeling phase
- Proliferative phase (Correct answer)
- Hemostasis phase
- Inflammatory phase
Correct answer: Proliferative phase
The proliferative phase (days 4–21) is dominated by fibroblast migration and collagen synthesis, along with angiogenesis and wound contraction.
Question 2: What does the Chvostek symbol mean?
- Poor state of nutrition
- Clinical signs of hypocalcemia (Correct answer)
- Observing for facial movement
- minimum of 3 inches, maximum of 6 inches
Correct answer: Clinical signs of hypocalcemia
Chvostek's sign is a clinical test used to assess for hypocalcemia, which is an abnormally low level of calcium in the blood. The sign is positive if a twitching of the facial muscles occurs when the facial nerve is tapped anterior to the earlobe. This involuntary twitching indicates neuromuscular irritability caused by the low calcium levels, making it a key indicator of this electrolyte imbalance.
Question 3: Under CCI's requirements, which of the following best describes the eligibility criterion related to first assisting hours before sitting for the CRNFA exam?
- 500 hours within the past 2 years (Correct answer)
- 1,500 hours within the past 5 years
- 2,000 hours within the past 3 years
- 750 hours within the past 1 year
Correct answer: 500 hours within the past 2 years
CCI requires documentation of a minimum of 500 hours of first assisting experience within the 2 years preceding application.
Question 4: A Harrington ('sweetheart') retractor is most commonly used to retract which structure?
- Brain tissue during craniotomy
- The liver during upper abdominal surgery (Correct answer)
- The bladder during pelvic surgery
- The lung during thoracotomy
Correct answer: The liver during upper abdominal surgery
The Harrington retractor, named for its heart-shaped blade, is designed to lift and retract the liver and spleen during upper abdominal procedures.
Question 5: The patient's nurse informed her that she should remain in bed following her needle liver biopsy. The patient questioned why she was required to remain in bed after the surgery. What is the patient to be taught by the nurse?
- Bed rest is maintained in order to prevent stitches from opening
- Resting in bed will stop the patient from falling because anesthetic will be administered.
- There is a high risk of bleeding post biopsy due to liver vascularity. (Correct answer)
- The patient will be tired after the procedure and should get some rest.
Correct answer: There is a high risk of bleeding post biopsy due to liver vascularity.
The liver is a highly vascular organ, meaning it has a rich blood supply. A needle liver biopsy involves puncturing the liver, which carries a significant risk of bleeding or hemorrhage from the biopsy site. Therefore, post-procedure bed rest, often in a right lateral position, is crucial to apply pressure to the biopsy site and minimize the risk of bleeding complications by allowing the puncture site to seal.
Question 6: AORN's Recommended Practice for Sterile Technique states that a sterile field is considered contaminated when:
- A scrub person touches a sterile item with sterile gloves
- A sterile item falls below the level of the sterile field table (Correct answer)
- Sterile saline is poured into a sterile basin
- The surgeon repositions within the sterile field
Correct answer: A sterile item falls below the level of the sterile field table
Items that fall below the table edge or waist level are considered contaminated per AORN sterile technique guidelines.
Question 7: Which electrosurgical mode uses a continuous waveform to achieve tissue cutting with minimal hemostasis?
- Bipolar mode
- Coagulation mode
- Cut mode (Correct answer)
- Blend mode
Correct answer: Cut mode
The cut mode delivers a continuous, unmodulated waveform that rapidly vaporizes tissue, producing a clean cut with minimal lateral thermal spread.
Question 8: When using monopolar electrosurgery, the CRNFA should ensure the dispersive electrode (grounding pad) is placed:
- On the patient's back regardless of surgical site location
- On any dry, hairless skin surface available
- On a well-vascularized muscle mass close to the operative site (Correct answer)
- Over a bony prominence for secure adherence
Correct answer: On a well-vascularized muscle mass close to the operative site
The dispersive electrode must be placed on a well-vascularized site near the surgical field to ensure adequate current dispersion and reduce burn risk.
Question 9: AORN's Guideline for Safe Patient Handling and Movement recommends that the RNFA use which approach when transferring a patient from the OR table?
- Patient transfer safety is solely the responsibility of the transport aide
- Manual lifting by two team members without assistive devices for routine transfers
- The RNFA should transfer the patient independently to save team time
- A mechanical lateral transfer device with adequate team members to ensure safe movement (Correct answer)
Correct answer: A mechanical lateral transfer device with adequate team members to ensure safe movement
AORN's safe patient handling guideline mandates the use of mechanical transfer aids and adequate personnel to reduce musculoskeletal injury risk for both patients and staff.
Question 10: Which type of wound healing is occurring when a surgeon deliberately leaves a contaminated wound open and allows it to close gradually from the base?
- Quaternary intention
- Tertiary intention (delayed primary closure)
- Secondary intention (Correct answer)
- Primary intention
Correct answer: Secondary intention
Secondary intention healing occurs when a wound is left open and closes by granulation tissue formation, wound contraction, and epithelialization.
Question 11: Which patient factor is the single greatest systemic risk factor for surgical site infection?
- Uncontrolled diabetes mellitus (HbA1c > 8%) (Correct answer)
- Age over 65
- Obesity (BMI > 30)
- Smoking within the past year
Correct answer: Uncontrolled diabetes mellitus (HbA1c > 8%)
Uncontrolled diabetes mellitus impairs leukocyte function, reduces tissue perfusion, and provides a glucose-rich environment for bacterial growth, making it the strongest systemic SSI risk factor.
Question 12: Intraoperative awareness (unintended consciousness during general anesthesia) is most effectively monitored using which technology?
- Pulse oximetry
- End-tidal CO2 capnography
- Bispectral Index (BIS) monitor measuring processed EEG (Correct answer)
- Heart rate and blood pressure monitoring alone
Correct answer: Bispectral Index (BIS) monitor measuring processed EEG
The Bispectral Index (BIS) processes EEG signals to provide a numerical depth-of-anesthesia estimate, with values of 40–60 indicating adequate anesthesia for most surgical procedures.
Question 13: A surgical wound is classified as Class III (contaminated). Which statement best describes this wound?
- A wound with established infection and pus
- An elective clean case such as hernia repair
- Open accidental wounds or cases with major breaks in sterile technique or gross spillage from hollow viscus (Correct answer)
- A clean-contaminated case such as elective bowel resection
Correct answer: Open accidental wounds or cases with major breaks in sterile technique or gross spillage from hollow viscus
Class III (contaminated) wounds include open traumatic wounds, major sterile technique breaks, or gross gastrointestinal spillage, carrying a moderate-to-high SSI risk.
Question 14: A 55-year-old woman has been identified as having the precancerous disease Barrett's esophagus. The CNS is aware of every one of the following, with the exception of:
- Male sex
- GERD symptoms of over 10 years
- African-American race (Correct answer)
- Age
Correct answer: African-American race
Barrett's esophagus is a condition where the normal squamous lining of the esophagus is replaced by columnar epithelium, often due to chronic gastroesophageal reflux disease (GERD). Risk factors include male sex, prolonged GERD symptoms (over 10 years), and older age. African-American race is generally associated with a lower risk of Barrett's esophagus and esophageal adenocarcinoma, making it the exception among the listed factors.

Correct answer: Computer-based testing at Pearson VUE or comparable proctored centers
CCI delivers the CRNFA exam via computer-based testing through authorized testing centers, allowing candidates flexibility in scheduling.
Question 23: According to AORN guidelines, which type of instrument count should be performed before the surgical incision is closed?
- Only sponge counts are required before closure
- Sharps counts are performed only when the surgeon requests them
- All sponge, sharps, and instrument counts must be reconciled and documented (Correct answer)
- Counts are only required for procedures lasting more than two hours
Correct answer: All sponge, sharps, and instrument counts must be reconciled and documented
AORN requires a complete reconciliation of all sponge, sharps, and instrument counts before wound closure to prevent retained surgical items.
Question 24: Dead space in a wound is most dangerous because it:
- Collects serum and blood that serve as a bacterial culture medium, promoting infection and seroma (Correct answer)
- Causes excessive fibrosis
- Prevents re-epithelialization
- Increases wound tension on the skin
Correct answer: Collects serum and blood that serve as a bacterial culture medium, promoting infection and seroma
Dead space allows fluid accumulation, creating a seroma or hematoma that is an ideal medium for bacterial growth and dramatically increases infection and dehiscence risk.
Question 25: A patient reports a prior reaction to a 'caine' medication at the dentist. The CRNFA should prioritize communicating which concern to the anesthesia team?
- Possible allergy to amide or ester local anesthetics (Correct answer)
- Contraindication to general anesthesia
- Need for antihistamine premedication only
- Risk of malignant hyperthermia
Correct answer: Possible allergy to amide or ester local anesthetics
A prior reaction to local anesthetics used in dentistry may indicate allergy to amide or ester class agents, which must be clarified before administering local or regional anesthesia.
Question 26: A Balfour retractor with a center blade is most commonly used during which type of procedure?
- Craniotomy
- Orthopedic joint replacement
- Abdominal/pelvic surgery (Correct answer)
- Thoracotomy
Correct answer: Abdominal/pelvic surgery
The Balfour retractor is a self-retaining abdominal retractor with lateral blades and a central (bladder) blade used to hold the abdominal wall open during laparotomy.
Question 27: What is the primary risk of placing an ESU dispersive pad over a bony prominence or scar tissue?
- Generator malfunction
- Increased impedance causing inadequate current return and burns under the pad (Correct answer)
- Reduced electrical resistance leading to burns at the active electrode
- Excessive current density at the active electrode
Correct answer: Increased impedance causing inadequate current return and burns under the pad
Bony prominences and scar tissue have poor contact area, increasing impedance at the dispersive pad, which can cause current to concentrate and produce a burn under the pad.
Question 28: Which patient history finding should prompt the CRNFA to alert the surgeon about potential difficult airway management?
- Short neck, limited cervical extension, and prior difficult intubation (Correct answer)
- Use of an ACE inhibitor for hypertension
- Mild seasonal allergies
- Prior appendectomy under general anesthesia without complications
Correct answer: Short neck, limited cervical extension, and prior difficult intubation
Anatomical features such as short neck and limited cervical extension, combined with a history of prior difficult intubation, strongly predict difficult airway and must be communicated to the anesthesia team.
Question 29: When the CRNFA notes that the ESU active electrode is in contact with a retractor touching a different tissue plane than intended, which hazard is present?
- Patient plate burn
- Generator overload
- Alternate site burn (direct coupling) through the unintended tissue contact (Correct answer)
- Laser plume exposure
Correct answer: Alternate site burn (direct coupling) through the unintended tissue contact
Direct coupling occurs when the active electrode inadvertently contacts a metal retractor or other conductor, allowing current to flow to and burn unintended tissue far from the operative site.
Question 30: When reviewing a patient's medication list preoperatively, which class of medications requires the MOST immediate concern regarding intraoperative bleeding risk?
- Antihypertensives
- Thyroid hormone replacements
- Antiplatelet agents such as clopidogrel (Correct answer)
- Proton pump inhibitors
Correct answer: Antiplatelet agents such as clopidogrel
Antiplatelet agents like clopidogrel inhibit platelet aggregation and significantly increase intraoperative bleeding risk; cessation timing must be confirmed with the surgeon.
Question 31: Which preoperative information is most relevant when preparing the back table and anticipating intraoperative needs for a trauma patient?
- Insurance authorization status
- Mechanism of injury, estimated blood loss, and suspected injuries from imaging (Correct answer)
- Patient's prior surgical history only
- Patient's smoking history
Correct answer: Mechanism of injury, estimated blood loss, and suspected injuries from imaging
Mechanism of injury, estimated blood loss, and imaging findings guide the surgical team in preparing for damage control procedures, vascular instruments, and blood products.
Question 32: When using a monopolar electrosurgical unit (ESU), the dispersive electrode (grounding pad) should be placed:
- On the patient's chest regardless of operative site
- On a bony prominence near the operative site
- Over a large muscle mass with good vascularity, as close to the site as practical (Correct answer)
- On any dry, clean skin surface chosen for convenience
Correct answer: Over a large muscle mass with good vascularity, as close to the site as practical
The dispersive electrode must be placed over a large, well-vascularized muscle mass near the operative site to ensure complete current return and prevent burns.
Question 33: Which suture material is most appropriate for closing a contaminated abdominal wound where infection risk is high?
- Surgical gut (plain catgut)
- Nylon monofilament (non-absorbable) (Correct answer)
- Silk (braided non-absorbable)
- Polyglycolic acid (synthetic absorbable)
Correct answer: Nylon monofilament (non-absorbable)
Monofilament sutures like nylon harbor fewer bacteria than braided sutures and are preferred in contaminated wounds.
Question 34: Which type of needle holder is most appropriate when suturing delicate cardiovascular tissue?
- Mayo-Hegar needle holder
- Castroviejo needle holder (Correct answer)
- Hegar needle holder
- Crile-Wood needle holder

Question 35: How many continuing education hours must a CRNFA complete during each 2-year renewal cycle to maintain certification with CCI?
- 30 hours
- 10 hours
- 20 hours (Correct answer)
- 15 hours
Correct answer: 20 hours
CCI requires 20 contact hours of continuing education relevant to perioperative nursing practice during each 2-year renewal period.
Question 36: The CRNFA is assisting with an open appendectomy when the appendix is found to be perforated. Which intraoperative action is most important to reduce postoperative infectious complications?
- Copious irrigation of the peritoneal cavity with warm saline (Correct answer)
- Application of a topical antibiotic-impregnated dressing to the bowel
- Packing the wound with iodoform gauze before fascial closure
- Immediate wound closure with retention sutures
Correct answer: Copious irrigation of the peritoneal cavity with warm saline
Copious peritoneal irrigation dilutes bacterial load and reduces the risk of postoperative abscess and peritonitis following perforation.
Question 37: Which of the following is a recognized role of the CRNFA that distinguishes them from a scrub technician?
- Providing tissue retraction, hemostasis, and suturing under surgeon direction (Correct answer)
- Counting sponges and sharps with the circulator
- Documenting intraoperative events in the nursing record
- Passing instruments from the sterile field
Correct answer: Providing tissue retraction, hemostasis, and suturing under surgeon direction
The CRNFA actively assists at the surgical field by retracting tissue, controlling bleeding, and suturing—tasks beyond the scope of a scrub technician.
Question 38: The CRNFA is assisting with a thyroidectomy when the surgeon suspects inadvertent damage to the recurrent laryngeal nerve. Which postoperative finding would confirm unilateral injury?
- Hoarseness and weak voice on the ipsilateral side (Correct answer)
- Bilateral stridor requiring emergent reintubation
- Dysphagia and aspiration on swallowing solids
- Hypocalcemia with positive Chvostek sign
Correct answer: Hoarseness and weak voice on the ipsilateral side
Unilateral recurrent laryngeal nerve injury typically presents with hoarseness due to ipsilateral vocal cord paralysis.
Question 39: When the RNFA identifies a break in sterile technique during a procedure, AORN standards require which immediate action?
- Notify only the surgeon and avoid alerting the rest of the team
- Continue the procedure silently and address the contamination after surgery
- Replace the contaminated item only if the surgeon requests it
- Announce the break to the team, correct it immediately, and document the event (Correct answer)
Correct answer: Announce the break to the team, correct it immediately, and document the event
AORN requires immediate disclosure, correction, and documentation of sterile technique breaks to maintain patient safety and transparency.
Question 40: When closing a laparotomy fascial layer, which suture placement technique is recommended to reduce the risk of wound dehiscence?
- Simple interrupted sutures placed 1 cm apart and 1 cm from the edge
- Running locking sutures placed as close to the edge as possible
- Figure-of-eight sutures placed 2 cm from the edge
- Small bites technique — sutures placed 5 mm from edge and 5 mm apart in a continuous fashion (Correct answer)
Correct answer: Small bites technique — sutures placed 5 mm from edge and 5 mm apart in a continuous fashion
The small bites technique (STITCH trial) using 5 mm bite size and 5 mm spacing in a running fashion significantly reduces incisional hernia and dehiscence compared to large bites.
Question 41: A patient has a documented allergy to iodine. Which preoperative skin antiseptic is the most appropriate substitute for iodine-based preparations?
- Benzalkonium chloride solution
- Chlorhexidine gluconate (CHG)-based solution (Correct answer)
- Isopropyl alcohol alone (70%)
- Hydrogen peroxide (3%)
Correct answer: Chlorhexidine gluconate (CHG)-based solution
Chlorhexidine gluconate is the evidence-based alternative to iodophor-based antiseptics and provides superior residual antimicrobial activity.
Question 42: In a continuous suture, which stitches are tied?
- The last stitch
- The first and last stitch (Correct answer)
- Every third stitch
- Every other stitch
Correct answer: The first and last stitch
A continuous suture involves a single strand of suture material that is run along the length of the wound without being tied off after each stitch. To secure the entire suture line, only the very first stitch is tied to anchor the suture, and then the final stitch at the end of the run is tied to complete the closure. This method provides a quick and efficient way to approximate tissues.
Question 43: Topical thrombin agents such as Thrombin-JMI work by activating which step in the coagulation cascade?
- Inhibiting fibrinolysis
- Converting prothrombin to thrombin
- Converting fibrinogen directly to fibrin (Correct answer)
- Activating platelets via ADP pathway
Correct answer: Converting fibrinogen directly to fibrin
Topical thrombin directly converts fibrinogen to fibrin, bypassing the intrinsic and extrinsic coagulation pathways to rapidly form a fibrin clot at the application site.
Question 44: A patient with a known latex allergy should be scheduled as which type of surgical case?
- Last case of the day to allow room decontamination
- No special scheduling is needed if latex-free gloves are used
- Requires a separate operating room only
- First case of the morning before latex particulates accumulate in the air (Correct answer)
Correct answer: First case of the morning before latex particulates accumulate in the air
Latex-allergic patients should be scheduled as the first case of the day when airborne latex particle levels are lowest.
Question 45: Which wound closure device provides the fastest skin closure and lowest rate of tissue strangulation in linear wounds?
- Steri-Strips (skin closure tapes)
- Subcuticular absorbable suture
- Skin staples (Correct answer)
- Interrupted monofilament sutures
Correct answer: Skin staples
Skin staples provide the fastest mechanical closure with minimal tissue handling and low risk of strangulation because they do not incorporate tissue within a loop under tension.
Question 46: Which anesthetic technique provides excellent analgesia for total knee arthroplasty while allowing early ambulation and reducing opioid requirements?
- Epidural analgesia with high thoracic placement
- Femoral nerve block or adductor canal block (regional anesthesia) (Correct answer)
- Intrathecal opioids without local anesthetic
- General anesthesia with IV opioids only
Correct answer: Femoral nerve block or adductor canal block (regional anesthesia)
Femoral nerve or adductor canal blocks provide targeted knee analgesia while preserving quadriceps strength for early mobilization and significantly reducing systemic opioid requirements.
Question 47: In which anatomical space does a retroperitoneal hematoma develop after injury to the aorta or inferior vena cava?
- Peritoneal cavity
- Preperitoneal space
- Retroperitoneal space (space of Retzius)
- Retroperitoneal space posterior to parietal peritoneum (Correct answer)
Correct answer: Retroperitoneal space posterior to parietal peritoneum
Retroperitoneal hematomas accumulate in the space posterior to the parietal peritoneum, where the aorta, IVC, and their branches reside.
Question 48: Which statement accurately describes CCI's stance on CRNFA candidates who are currently enrolled in a formal RNFA education program but have not yet completed it?
- They may apply using their anticipated graduation date as proof of eligibility
- They may sit for the exam provisionally and receive scores after program completion
- CCI waives the program requirement if the candidate holds a master's degree in nursing
- They are ineligible until both the program and required clinical hours are completed (Correct answer)
Correct answer: They are ineligible until both the program and required clinical hours are completed
CCI requires that candidates have fully completed an RNFA education program and documented the required first-assisting hours before they are eligible to test.
Question 49: When passing a sharp instrument to the surgeon on the sterile field, the CRNFA should use which safety technique?
- Pass sharp instruments only when the surgeon requests verbally
- Hand the instrument directly handle-first with the blade pointing toward the surgeon
- Place the instrument in a neutral zone (kidney basin) for the surgeon to pick up (Correct answer)
- Announce 'sharp passing' and hand directly with the tip covered
Correct answer: Place the instrument in a neutral zone (kidney basin) for the surgeon to pick up
The neutral zone (hands-free) technique places sharps in a designated zone for the surgeon to retrieve, preventing direct hand-to-hand transfer and reducing needlestick injuries.
Question 50: CCI was formerly known by which name before rebranding as the Competency and Credentialing Institute?
- National Certification Board: Perioperative Nursing (NCBPN) (Correct answer)
- Perioperative Nursing Certification Corporation (PNCC)
- American Board of Perioperative Nursing (ABPN)
- AORN Credentialing Center
Correct answer: National Certification Board: Perioperative Nursing (NCBPN)
CCI was previously called the National Certification Board: Perioperative Nursing (NCBPN) before adopting its current name to reflect its broader mission.
Question 51: Debridement of wounds:
- Keeps a wound moist
- Removes dead tissue from a wound (Correct answer)
- Closes a wound
- Cleans a wound
Correct answer: Removes dead tissue from a wound
Debridement is a critical step in wound care that involves the removal of necrotic (dead) tissue, foreign material, and exudate from a wound bed. This process is essential because dead tissue can harbor bacteria, impede granulation tissue formation, and delay wound healing. By removing devitalized tissue, debridement promotes a clean wound environment conducive to healthy tissue growth and closure.
Question 52: During a laparoscopic cholecystectomy, the CRNFA notices the surgeon is applying excessive traction on the cystic duct before the critical view of safety is achieved. What is the most appropriate action?
- Immediately cut the structure as directed
- Verbally communicate the concern and recommend pausing to identify anatomy (Correct answer)
- Request the anesthesiologist to alter the patient's position
- Document the concern and proceed without intervention
Correct answer: Verbally communicate the concern and recommend pausing to identify anatomy
The CRNFA must advocate for patient safety by communicating concerns about anatomic identification before irreversible actions are taken.
Question 53: AORN guidelines state that the RNFA's scope of practice must be defined by which combination of factors?
- State nurse practice act, institutional policies, and demonstrated clinical competency (Correct answer)
- AORN guidelines alone, without reference to state law
- Federal regulations only, which supersede state nurse practice acts
- Surgeon preference alone, regardless of institutional policies
Correct answer: State nurse practice act, institutional policies, and demonstrated clinical competency
AORN stipulates that the RNFA's scope is determined by state law, institutional credentialing policies, and documented competency—all three must align.
Question 54: Which maneuver, performed by the CRNFA or circulating nurse during rapid sequence intubation (RSI), helps prevent aspiration by occluding the esophagus?
- Jaw thrust
- Sellick maneuver (cricoid pressure) (Correct answer)
- Bimanual laryngoscopy
- Head-tilt chin-lift
Correct answer: Sellick maneuver (cricoid pressure)
Cricoid pressure (Sellick maneuver) compresses the cricoid cartilage against the esophagus to occlude it and prevent passive regurgitation during RSI until the cuff is inflated.
Question 55: Bone wax is most appropriately used to control bleeding from which type of source?
- Major arterial bleeding
- Capillary bleeding from skin edges
- Venous oozing from soft tissue
- Bleeding from cancellous bone surfaces (e.g., sternum or cranium) (Correct answer)
Correct answer: Bleeding from cancellous bone surfaces (e.g., sternum or cranium)
Bone wax is a mechanical hemostatic agent used specifically to tamponade bleeding from cut bone surfaces such as the sternum during cardiac surgery or the cranium during neurosurgery.
Question 56: In the Trendelenburg position used for pelvic surgery, the CRNFA must monitor for which specific respiratory complication?
- Decreased functional residual capacity and increased risk of atelectasis (Correct answer)
- Pulmonary embolism from venous stasis in the lower extremities
- Tension pneumothorax from positive pressure ventilation
- Carbon dioxide retention from subcutaneous emphysema
Correct answer: Decreased functional residual capacity and increased risk of atelectasis
In Trendelenburg, abdominal contents shift cephalad, reducing functional residual capacity and increasing atelectasis and ventilation challenges.
Question 57: To determine the arterial blood flow to the hands during an evaluation, what test is used?
- Finkel steins Test
- Cozens Test
- Allens Test (Correct answer)
- Wrist Press
Correct answer: Allens Test
The Allen's Test is a clinical assessment used to evaluate the patency of the radial and ulnar arteries, which supply blood to the hand. It is performed before procedures that might compromise one of these arteries, such as arterial blood gas sampling or radial artery cannulation. The test helps ensure that there is adequate collateral circulation to the hand from the other artery if one is occluded.
Question 58: Which of the following acts as warfarin's (Coumadin) counterbalance?
- Protamine sulfate
- Magnesuim
- Saline
- Vitamin K (Correct answer)
Correct answer: Vitamin K
Warfarin (Coumadin) is an anticoagulant that works by interfering with the synthesis of vitamin K-dependent clotting factors in the liver. Therefore, Vitamin K acts as its direct antidote or counterbalance. Administering Vitamin K can reverse the anticoagulant effects of warfarin by promoting the production of these clotting factors, which is crucial in cases of excessive bleeding or overdose.
Question 59: A diabetic patient's point-of-care blood glucose before surgery reads 320 mg/dL. The CRNFA should:
- Notify the anesthesiologist and surgeon immediately before proceeding (Correct answer)
- Document the finding and proceed with the scheduled case
- Recheck in 30 minutes and proceed if unchanged
- Administer insulin per the sliding scale and proceed
Correct answer: Notify the anesthesiologist and surgeon immediately before proceeding
A preoperative blood glucose of 320 mg/dL represents significant hyperglycemia that increases infection risk and may require insulin management prior to proceeding with elective surgery.
Question 60: Dantrolene sodium is the definitive treatment for malignant hyperthermia. What is the initial recommended IV bolus dose?
- 2.5 mg/kg, repeated up to 10 mg/kg total if needed (Correct answer)
- 0.5 mg/kg
- 5 mg/kg once
- 10 mg/kg as a single bolus
Correct answer: 2.5 mg/kg, repeated up to 10 mg/kg total if needed
The initial dantrolene dose is 2.5 mg/kg IV bolus, repeated every 5 minutes up to 10 mg/kg (or until symptoms resolve) for malignant hyperthermia treatment.
Question 61: Which structure passes through the femoral triangle and is at risk during inguinal hernia repair?
- Lateral femoral cutaneous nerve
- Femoral nerve (Correct answer)
- Sciatic nerve
- Obturator nerve
Correct answer: Femoral nerve
The femoral nerve lies in the femoral triangle lateral to the femoral artery and must be avoided during inguinal hernia repair to prevent motor deficit of the quadriceps.
Question 62: A patient receiving epidural analgesia develops sudden hypotension, bradycardia, and respiratory distress after a bolus dose. The CRNFA should recognize this as which complication?
- Anaphylaxis to the local anesthetic
- Epidural hematoma
- Opioid-induced respiratory depression
- Total spinal (high spinal block with hemodynamic collapse) (Correct answer)
Correct answer: Total spinal (high spinal block with hemodynamic collapse)
Total spinal (accidental intrathecal injection of an epidural dose) causes rapid-onset profound hypotension, bradycardia, and respiratory failure requiring immediate vasopressor and airway support.
Question 63: The CRNFA exam administered by CCI is developed using content from which primary source that outlines the scope of RN first assistant practice?
- ASPAN Perianesthesia Standards
- AORN's RN First Assistant: Scope and Standards of Practice (Correct answer)
- AST Surgical Technology Standards
- ANA Nursing Scope and Standards
Correct answer: AORN's RN First Assistant: Scope and Standards of Practice
The CRNFA exam is based on AORN's RN First Assistant: An Expanded Perioperative Nursing Role, which defines RNFA scope and standards.
Question 64: Which suture technique is most appropriate for ligating the pedicle of the appendix at its base?
- Simple ligation with a free tie (Correct answer)
- Running locking suture
- Purse-string suture
- Figure-of-eight suture
Correct answer: Simple ligation with a free tie
The appendiceal stump is typically managed with a simple free tie (ligation) or endoloop at its base to secure the mesoappendix vessels and prevent bleeding.
Question 65: Which element of the WHO Surgical Safety Checklist is performed immediately before skin incision and requires ALL team members to stop and verbally confirm?
- Sign-in (pre-induction)
- Hand-off (end of case)
- Sign-out (before closing)
- Time-out (before skin incision) (Correct answer)
Correct answer: Time-out (before skin incision)
The Time-Out is performed immediately before incision with all team members actively confirming patient identity, site, procedure, team introductions, and critical concerns.
Question 66: During a right colectomy, which structure lies in close proximity to the ileocolic vessels and must be identified to avoid injury?
- Superior mesenteric vein
- Right gonadal vein
- Right renal vein
- Right ureter (Correct answer)
Correct answer: Right ureter
The right ureter runs retroperitoneally along the psoas muscle near the ileocolic vessels and must be identified before ligation during right colectomy.
Question 67: The CRNFA certification renewal cycle through CCI is based on what time period?
- 3 years
- 1 year
- 5 years
- 2 years (Correct answer)
Correct answer: 2 years
CCI CRNFA certification must be renewed every 2 years to confirm ongoing competency and continuing education compliance.
Question 68: During a thyroidectomy, which nerve must be identified and preserved to prevent permanent hoarseness?
- Internal laryngeal nerve
- Recurrent laryngeal nerve (Correct answer)
- Glossopharyngeal nerve
- External laryngeal nerve
Correct answer: Recurrent laryngeal nerve
The recurrent laryngeal nerve innervates all intrinsic laryngeal muscles except the cricothyroid, and bilateral injury causes permanent hoarseness or airway obstruction.
Question 69: Which volatile anesthetic agent is most strongly associated with triggering malignant hyperthermia in susceptible patients?
- Propofol
- Nitrous oxide
- Succinylcholine and all volatile halogenated agents (e.g., sevoflurane, desflurane) (Correct answer)
- Ketamine
Correct answer: Succinylcholine and all volatile halogenated agents (e.g., sevoflurane, desflurane)
Malignant hyperthermia is triggered by succinylcholine and all halogenated volatile anesthetic agents; nitrous oxide, propofol, and ketamine are safe in MH-susceptible patients.
Question 70: Preoperative marking of the surgical site is performed to prevent which type of adverse surgical event?
- Postoperative wound infection
- Wrong-site, wrong-side, or wrong-procedure surgery (Correct answer)
- Deep vein thrombosis
- Anesthesia awareness
Correct answer: Wrong-site, wrong-side, or wrong-procedure surgery
Surgical site marking is a Joint Commission Universal Protocol requirement specifically designed to prevent wrong-site, wrong-side, and wrong-procedure surgeries.
Question 71: The McBurney's point, commonly used in appendectomy, is located where?
- One-third the distance from the umbilicus to the right anterior superior iliac spine
- One-half the distance from the pubic symphysis to the right ASIS
- One-third the distance from the right ASIS to the umbilicus (Correct answer)
- Midway between the umbilicus and the right ASIS
Correct answer: One-third the distance from the right ASIS to the umbilicus
McBurney's point is located one-third of the distance from the right anterior superior iliac spine to the umbilicus, overlying the base of the appendix.
Question 72: In the context of AORN's ethical framework, when the RNFA disagrees with a surgical decision that may harm the patient, the appropriate first action is to:
- Leave the sterile field in protest of the decision
- Immediately contact the hospital administrator during the procedure
- Voice concerns directly to the surgeon and document the concern (Correct answer)
- Remain silent and carry out the surgeon's instructions without question
Correct answer: Voice concerns directly to the surgeon and document the concern
AORN's ethical standards require the RNFA to advocate for the patient by expressing concerns through appropriate channels, starting with direct communication.
Question 73: The purpose of pre-oxygenation (denitrogenation) before induction of general anesthesia is to:
- Extend the safe apnea window by maximizing lung oxygen reserves before intubation (Correct answer)
- Prevent laryngospasm
- Reduce anesthetic agent requirements
- Prevent malignant hyperthermia
Correct answer: Extend the safe apnea window by maximizing lung oxygen reserves before intubation
Pre-oxygenation with 100% O2 for 3–5 minutes replaces nitrogen in functional residual capacity with oxygen, extending the safe apneic window from ~1 minute to 3–8 minutes.
Question 74: The CRNFA notes active arterial spurting from a 3 mm vessel during dissection. The MOST appropriate immediate action is to:
- Activate the ESU at maximum coagulation
- Apply a hemostatic clip blindly to the bleeding area
- Apply direct digital pressure immediately and notify the surgeon (Correct answer)
- Apply topical thrombin and pack with gauze
Correct answer: Apply direct digital pressure immediately and notify the surgeon
Direct digital pressure is the safest and most immediate first response to control active arterial bleeding while preparing for definitive hemostasis with the surgeon.
Question 75: When tying a square knot during wound closure, the CRNFA notices the knot is sliding rather than locking. This most likely indicates:
- The throws were made in the same direction, creating a slip knot (Correct answer)
- Excessive tension was applied to the first throw
- The suture material is too thick for the tissue
- The suture was moistened before tying
Correct answer: The throws were made in the same direction, creating a slip knot
A granny (slip) knot results when both throws are in the same direction; a square knot requires alternating throw directions.
Question 76: The CRNFA is using an argon beam coagulator (ABC). A key safety precaution specific to this device is:
- Never using it near the bowel
- Soaking the tip in saline before use
- Ensuring the patient's dispersive electrode is removed before activation
- Maintaining low gas flow to prevent pneumoperitoneum in laparoscopy (Correct answer)
Correct answer: Maintaining low gas flow to prevent pneumoperitoneum in laparoscopy
In laparoscopic procedures, argon gas from the ABC can rapidly increase intraabdominal pressure, causing pneumoperitoneum complications; gas evacuation must be managed carefully.
Question 77: Which statement regarding DFV (deficient fluid volume) is the most accurate?
- This is an imbalance caused by the patients condition
- None of the answers below
- This is an imbalance caused by too much heat
- This is an imbalance in the isotonic body fluids (Correct answer)
Correct answer: This is an imbalance in the isotonic body fluids
Deficient Fluid Volume (DFV), often referred to as hypovolemia or isotonic dehydration, occurs when there is a proportional loss of both water and electrolytes from the extracellular fluid compartment. This leads to a decrease in the total circulating blood volume without a significant shift in fluid between intracellular and extracellular spaces. It is characterized by a reduction in isotonic body fluids, impacting overall fluid balance and organ perfusion.
Question 78: The CRNFA should count surgical sponges, sharps, and instruments at which standardized time points?
- Only at the end of surgery
- At the start and once at the end of surgery
- Only when the circulator requests a count
- Before the procedure, before closure of a body cavity, before skin closure, and at time of relief of any team member (Correct answer)
Correct answer: Before the procedure, before closure of a body cavity, before skin closure, and at time of relief of any team member
AORN standards require four standardized count times: initial count, before body cavity closure, before wound closure, and at personnel relief — to prevent retained surgical items.
Question 79: AORN's position statement on the RNFA specifies that the first assistant role differs from the scrub role in that the RNFA:
- Functions exclusively as a circulator with additional sterile duties as needed
- Primarily passes instruments and maintains the sterile field from the scrub position
- Actively assists at the operative field by manipulating tissue, providing exposure, and achieving hemostasis (Correct answer)
- Can only perform first assistant duties if credentialed as a surgical technologist
Correct answer: Actively assists at the operative field by manipulating tissue, providing exposure, and achieving hemostasis
AORN distinguishes the RNFA role as an active participant in the surgical procedure—not merely an instrument handler—performing tissue manipulation, exposure, and hemostasis.
Question 80: When performing blunt dissection in surgery, the CRNFA should use which technique to minimize tissue trauma?
- Gentle spreading along anatomical tissue planes using the tips of a hemostat (Correct answer)
- Rapid sweeping motions parallel to neurovascular structures
- Finger-fracture technique applied perpendicular to the tissue
- Using electrocautery on a low setting as an alternative to sharp dissection
Correct answer: Gentle spreading along anatomical tissue planes using the tips of a hemostat
Gentle spreading along natural tissue planes with hemostatic tips preserves neurovascular structures and reduces collateral tissue damage.
Question 81: Which of the following is a contraindication to the use of absorbable gelatin sponge (Gelfoam) as a topical hemostatic agent?
- Bleeding from a superficial skin laceration
- Use in areas where brain or spinal cord compression could occur (Correct answer)
- Capillary ooze in muscle tissue
- Bleeding from a hepatic laceration surface
Correct answer: Use in areas where brain or spinal cord compression could occur
Gelfoam swells as it absorbs blood and should not be used in closed spaces such as the brain or spinal cord where expansion could cause compression injury.
Question 82: Which preoperative finding most strongly warrants postponement of elective surgery?
- Random blood glucose of 180 mg/dL in a known diabetic
- Blood pressure of 148/88 mmHg
- Serum potassium of 2.8 mEq/L (Correct answer)
- Hemoglobin of 11.5 g/dL in a stable patient
Correct answer: Serum potassium of 2.8 mEq/L
A serum potassium below 3.0 mEq/L (hypokalemia) increases risk of life-threatening cardiac arrhythmias during anesthesia and warrants correction before elective surgery.
Question 83: The obturator nerve exits the pelvis through which foramen and may be injured during lymph node dissection?
- Obturator foramen (Correct answer)
- Lesser sciatic foramen
- Greater sciatic foramen
- Inguinal canal
Correct answer: Obturator foramen
The obturator nerve exits the pelvis through the obturator foramen and is at risk during obturator lymph node dissection for gynecologic or urologic cancers.
Question 84: Which absorbable hemostatic agent is derived from oxidized regenerated cellulose and works by absorbing blood to form a gel clot?
- Surgicel (oxidized regenerated cellulose) (Correct answer)
- Gelfoam (gelatin sponge)
- Avitene (microfibrillar collagen)
- FloSeal (gelatin matrix)
Correct answer: Surgicel (oxidized regenerated cellulose)
Surgicel is made of oxidized regenerated cellulose which, when wet with blood, forms a dark gelatinous mass that promotes clot formation and is absorbed within 1–2 weeks.
Question 85: The portal triad in the liver consists of which structures?
- Hepatic artery, hepatic vein, lymphatic vessel
- Hepatic vein, bile duct, lymphatic vessel
- Portal vein, hepatic vein, bile duct
- Portal vein, hepatic artery, bile duct (Correct answer)
Correct answer: Portal vein, hepatic artery, bile duct
The portal triad consists of a branch of the portal vein, hepatic artery, and bile duct running together within connective tissue.
Question 86: AORN's Guideline for Electrosurgery recommends that the RNFA take which precaution when using electrosurgical units (ESUs) near implanted electronic devices?
- ESU use is always contraindicated in patients with implanted electronic devices
- Disable the implanted device remotely before all electrosurgical use
- Use bipolar electrosurgery freely without any additional precautions
- Consult the device manufacturer's guidelines and coordinate with the cardiologist before use (Correct answer)
Correct answer: Consult the device manufacturer's guidelines and coordinate with the cardiologist before use
AORN recommends individualized assessment per manufacturer guidance and interdisciplinary collaboration before ESU use in patients with pacemakers or ICDs.
Question 87: Which intraoperative physiologic parameter, if consistently below 95%, requires immediate intervention by the surgical team?
- End-tidal CO2 of 38 mmHg
- Temperature of 36.2°C
- Urine output of 0.5 mL/kg/hr
- SpO2 (pulse oximetry oxygen saturation) (Correct answer)
Correct answer: SpO2 (pulse oximetry oxygen saturation)
SpO2 below 95% indicates hypoxemia requiring immediate airway and ventilatory assessment; the lower alarm limit on most anesthesia monitors is set at 95%.
Question 88: Which anatomical structure divides the liver into right and left lobes based on functional segmentation (Cantlie's line)?
- Falciform ligament
- Middle hepatic vein plane (Cantlie's line) (Correct answer)
- Round ligament
- Right hepatic vein
Correct answer: Middle hepatic vein plane (Cantlie's line)
Cantlie's line runs through the plane of the middle hepatic vein dividing the liver into true right and left functional lobes, not the falciform ligament.
Question 89: According to AORN, the primary rationale for performing a pre-incision time-out is to:
- Verify patient identity, correct procedure, correct site, and correct position before incision (Correct answer)
- Give the circulator time to complete the count sheet
- Provide an opportunity for the surgeon to review intraoperative imaging results
- Allow the anesthesia team to complete documentation before surgery begins
Correct answer: Verify patient identity, correct procedure, correct site, and correct position before incision
AORN's time-out procedure is designed to prevent wrong-patient, wrong-site, and wrong-procedure events through active team verification.
Question 90: Which anatomical landmark is used to identify the ureter during pelvic surgery?
- It runs parallel to the femoral nerve
- It crosses under the ovarian vein
- It crosses over the external iliac artery (Correct answer)
- It lies medial to the psoas muscle only
Correct answer: It crosses over the external iliac artery
The ureter crosses over the bifurcation of the common iliac artery (or the external iliac artery) and is identified at this crossing point during pelvic dissection.
Question 91: What are the names of stitches that are applied horizontally to the wound?
- Vertical mattress
- Horizontal mattress (Correct answer)
- Simple interrupted
- Foot drop
Correct answer: Horizontal mattress
The horizontal mattress suture is a type of interrupted suture that provides excellent wound eversion and strength. It involves passing the needle through the skin on one side, then across the wound to the other side, and then back across the wound in a horizontal fashion before tying the knot. This technique distributes tension evenly along the wound edges, promoting better healing and cosmetic outcomes.
Question 92: Under AORN standards, a latex-safe environment in the OR requires which of the following?
- Simply placing a latex allergy sign on the door while continuing to use latex gloves
- Administering prophylactic antihistamines as the sole latex precaution
- Removing all latex-containing products from the room and using non-latex alternatives throughout the procedure (Correct answer)
- Using latex gloves only during the closing phase of surgery
Correct answer: Removing all latex-containing products from the room and using non-latex alternatives throughout the procedure
AORN requires complete removal of latex-containing items and substitution with non-latex products to create a truly latex-safe environment.
Question 93: This ligament is made up of two peritoneal folds that stretch laterally, posteriorly, and downward from the uterus.
- Extension
- Broad ligament (Correct answer)
- Urinary bladder
- Trochlear-eye movement
Correct answer: Broad ligament
The broad ligament is a wide fold of peritoneum that extends from the sides of the uterus to the walls and floor of the pelvis. It is composed of two layers of peritoneum and contains various structures, including blood vessels, nerves, and connective tissue. Its primary function is to support the uterus and ovaries within the pelvic cavity, anchoring them in place.
Question 94: A patient positioned in the lithotomy position for a prolonged perineal procedure is at greatest risk for which compartment syndrome?
- Gluteal compartment syndrome from ischemia in the buttocks
- Lower leg (anterior compartment) syndrome from leg holder pressure (Correct answer)
- Forearm compartment syndrome from IV infiltration
- Abdominal compartment syndrome from bowel edema
Correct answer: Lower leg (anterior compartment) syndrome from leg holder pressure
Prolonged lithotomy position compresses lower leg compartments and reduces perfusion, making anterior compartment syndrome of the lower leg a recognized complication.
Question 95: Which nerve is at risk during a mastectomy and, if injured, causes 'winged scapula'?
- Medial pectoral nerve
- Intercostobrachial nerve
- Long thoracic nerve (Correct answer)
- Thoracodorsal nerve
Correct answer: Long thoracic nerve
Injury to the long thoracic nerve during mastectomy denervates the serratus anterior muscle, causing the medial scapular border to wing outward.
Question 96: During a laparoscopic procedure, the surgeon asks the CRNFA to adjust the monopolar ESU settings. Which finding on the ESU display indicates that the dispersive pad alarm is activated?
- Power output exceeds 100 watts
- The display shows 'max output' warning
- The contact quality monitor indicator shows poor pad contact (Correct answer)
- The generator automatically switches to bipolar mode
Correct answer: The contact quality monitor indicator shows poor pad contact
Modern ESUs with contact quality monitoring display a poor contact warning when the dispersive pad has inadequate skin contact, preventing unsafe current return.
Question 97: Which patient position change should the CRNFA anticipate to prevent venous air embolism when opening the internal jugular vein during a neck dissection?
- Left lateral decubitus
- Reverse Trendelenburg (head up) position
- Prone position
- Trendelenburg (head down) position (Correct answer)
Correct answer: Trendelenburg (head down) position
Trendelenburg positioning increases central venous pressure in neck veins, reducing the risk of air entrainment if the internal jugular vein is inadvertently opened.
Question 98: Which of the following organizations manages the country's organ transplant waiting list?
- Organ Procurement Organization
- National Conference of Commissioners on Uniform State Laws
- United Network for Organ Sharing (Correct answer)
- Department of Health and Human Services
Correct answer: United Network for Organ Sharing
The United Network for Organ Sharing (UNOS) is a private, non-profit organization that manages the nation's organ transplant system under contract with the federal government. UNOS maintains the national computer database of all patients waiting for transplants and all organ donors, ensuring fair and equitable allocation of organs based on established medical criteria. Their role is critical in coordinating the complex process of organ donation and transplantation across the United States.
Question 99: When reviewing the preoperative checklist, which item related to NPO status is most critical for patient safety?
- Patient drank 8 oz of clear liquids 4 hours ago per enhanced recovery protocol
- Patient has been NPO for 3 hours for solids
- Patient had a full meal 2 hours before surgery (Correct answer)
- Patient consumed a light meal 8 hours ago
Correct answer: Patient had a full meal 2 hours before surgery
A full meal within 2 hours of surgery violates NPO guidelines (8 hours for solids) and places the patient at high risk for aspiration pneumonia under anesthesia.
Question 100: The CRNFA notes that a laparoscopic trocar is labeled '12 mm.' This measurement refers to the:
- Outer diameter of the trocar cannula (Correct answer)
- Diameter of the insufflation port
- Inner diameter of the trocar cannula
- Length of the trocar sleeve
Correct answer: Outer diameter of the trocar cannula
Trocar sizes are designated by the outer diameter of the cannula, which determines the largest instrument that can be passed through it.
Question 101: Which layer of the abdominal wall provides the greatest strength and is most critical to include in a secure fascial closure?
- Anterior rectus sheath (external oblique aponeurosis) (Correct answer)
- Skin and subcutaneous fat
- External and internal oblique muscles
- Transversalis fascia and posterior rectus sheath
Correct answer: Anterior rectus sheath (external oblique aponeurosis)
The anterior rectus sheath (external oblique aponeurosis) is the strongest layer of the abdominal wall and must be securely closed to prevent hernia formation.
Question 102: Which drain type works by passive capillary action and does not require a vacuum reservoir?
- Penrose drain (Correct answer)
- Jackson-Pratt drain
- Blake drain
- Blake grenade drain
Correct answer: Penrose drain
The Penrose drain is a soft rubber flat drain that relies on passive capillary flow and gravity, requiring no vacuum; it allows drainage from the wound to the outside.
Question 103: A ligating clip should be placed at what minimum distance from the planned transection point to ensure secure hemostasis?
- 2–3 mm (Correct answer)
- 1 mm
- 5 mm or more
- 0.5 mm
Correct answer: 2–3 mm
Clips should be placed at least 2–3 mm from the transection site to allow a secure bite of tissue and prevent slippage off the vessel end.
Question 104: Which fascial layer of the neck must be incised during central venous catheter insertion via the internal jugular approach?
- Superficial cervical fascia
- Investing layer of deep cervical fascia (Correct answer)
- Buccopharyngeal fascia
- Prevertebral fascia
Correct answer: Investing layer of deep cervical fascia
The investing layer of the deep cervical fascia encloses the sternocleidomastoid muscle and must be penetrated to access the internal jugular vein.
Question 105: A patient develops a seroma 10 days after a mastectomy. The CRNFA understands that the most common contributing factor is:
- Wound infection with S. aureus
- Excessive postoperative activity
- Lymphatic and small blood vessel disruption during flap creation leading to fluid accumulation (Correct answer)
- Use of absorbable sutures in the wound
Correct answer: Lymphatic and small blood vessel disruption during flap creation leading to fluid accumulation
Mastectomy seromas form when lymphatic and small vessels in the dissection planes continue to weep serous fluid into the dead space beneath skin flaps.
Question 106: According to CCI guidelines, which scenario would result in automatic ineligibility for the CRNFA examination?
- Having a felony conviction on one's record without CCI review and approval (Correct answer)
- Working in a facility that does not allow RNFAs to perform tissue handling
- Holding a CNOR that expires within 90 days of the exam application date
- Practicing first assisting in an ambulatory surgery center rather than a hospital
Correct answer: Having a felony conviction on one's record without CCI review and approval
CCI requires applicants to disclose legal history, and an unreviewed felony conviction can result in ineligibility for credentialing.
Question 107: A Bookwalter retractor system is best classified as which type of retractor?
- Malleable retractor
- Vein retractor
- Hand-held retractor
- Self-retaining retractor (Correct answer)
Correct answer: Self-retaining retractor
The Bookwalter is a self-retaining retractor system that attaches to the OR table and holds tissue without requiring manual assistance.
Question 108: The CRNFA should ensure that which safety device is applied before draping to minimize risk of patient movement causing injury during positioning under anesthesia?
- Heating blanket
- Electrosurgical return pad
- Sequential compression devices
- Safety strap or padded restraint securing the patient to the table (Correct answer)
Correct answer: Safety strap or padded restraint securing the patient to the table
A safety strap or padded restraint must be applied across the patient's thighs before draping to prevent falls if the patient moves, is inadvertently bumped, or the table is repositioned.
Question 109: Which surgical positioning complication is most associated with the lithotomy position?
- Radial nerve palsy
- Compartment syndrome of the lower legs and common peroneal nerve palsy (Correct answer)
- Cervical spine injury
- Brachial plexus injury
Correct answer: Compartment syndrome of the lower legs and common peroneal nerve palsy
Prolonged lithotomy position compresses the common peroneal nerve at the fibular head against the stirrups and restricts calf perfusion, leading to compartment syndrome and peroneal nerve palsy.
Question 110: During a Whipple procedure (pancreaticoduodenectomy), the CRNFA should anticipate the greatest risk of significant hemorrhage during which step?
- Gastrojejunostomy reconstruction
- Dissection and division of the portal vein tributaries (Correct answer)
- Jejunojejunostomy anastomosis
- Cholecystectomy and common bile duct division
Correct answer: Dissection and division of the portal vein tributaries
Dissection around the portal vein and superior mesenteric vessels carries the highest hemorrhage risk due to proximity of high-flow venous structures.
Question 111: What is the process of repositioning the bladder flap peritoneum to the posterior cul-de-sac peritoneum known as?
- 3.5-5.0
- fimbria
- reperitonealization (Correct answer)
- 8.8-10
Correct answer: reperitonealization
Reperitonealization is a surgical technique, often performed during gynecological procedures like hysterectomy, where the peritoneum (the membrane lining the abdominal cavity) is reapproximated or repositioned. Specifically, repositioning the bladder flap peritoneum to the posterior cul-de-sac peritoneum aims to cover raw surfaces, prevent adhesions, and restore anatomical integrity. This helps to minimize potential complications and promote healing.
Question 112: Proper tissue handling during dissection requires that the CRNFA use instruments that minimize which primary cause of delayed wound healing?
- Wound closure under slight tension
- Use of absorbable sutures
- Excessive suture material
- Tissue crush injury and devitalization from traumatic handling (Correct answer)
Correct answer: Tissue crush injury and devitalization from traumatic handling
Crush injury from traumatic forceps and excessive tissue manipulation devitalizes tissue, impairing blood supply and increasing infection and dehiscence risk.
Question 113: The CRNFA is assisting with a bowel resection and selects a GIA stapler. GIA stands for:
- General incision apparatus
- Gastrointestinal insertion apparatus
- Gastric intestinal approximation
- Gastrointestinal anastomosis (Correct answer)
Correct answer: Gastrointestinal anastomosis
GIA stands for gastrointestinal anastomosis; this linear stapler simultaneously places two double rows of staples and cuts between them.
Question 114: The CRNFA selects a TA (thoracoabdominal) stapler. Which statement BEST describes its function?
- It clips individual vessels one at a time
- It places one or two rows of staples without dividing the tissue (Correct answer)
- It creates a circular anastomosis end-to-end
- It places staples and simultaneously divides tissue between two staple lines
Correct answer: It places one or two rows of staples without dividing the tissue
The TA stapler applies one or two rows of staples to close tissue but does NOT cut, requiring the surgeon to manually transect the tissue afterward.
Question 115: Which of the following is one of the most important factors in figuring out how to effectively remove the smoke during laser surgery?
- None of the above
- The amount of the smoke plume produced (Correct answer)
- How long the smoke plume last
- The color of the smoke plume
Correct answer: The amount of the smoke plume produced
During laser surgery, a smoke plume is generated, which contains cellular debris, blood fragments, and potentially viable viruses and carcinogens. The amount of smoke plume produced directly correlates with the volume of hazardous airborne contaminants that need to be removed to ensure the safety of the surgical team and patient. Effective smoke evacuation systems must be appropriately sized and positioned to capture this plume efficiently, preventing inhalation exposure.
Question 116: Under CCI policy, a CRNFA who transitions to a management role and stops first assisting should:
- Allow the CRNFA to lapse since she is no longer practicing in the role
- Retain the CRNFA credential indefinitely as long as the CNOR remains active
- Petition AORN for a management-track credential that replaces the CRNFA
- Apply for inactive status with CCI and maintain CE to reactivate later (Correct answer)
Correct answer: Apply for inactive status with CCI and maintain CE to reactivate later
CCI offers options for certificate holders who temporarily leave clinical practice, including inactive status arrangements that preserve the path to reactivation.
Question 117: Electrosurgical unit (ESU) current density is highest at which point in the circuit?
- Along the connecting cable
- The active electrode tip (Correct answer)
- Dispersive (grounding) pad
- The generator unit
Correct answer: The active electrode tip
Current density is highest at the small active electrode tip where tissue effect (cutting or coagulation) occurs, and lowest at the large dispersive pad where current spreads safely.
Question 118: Which suture material is most appropriate for a contaminated abdominal wound requiring fascial closure?
- Polydioxanone (PDS) — monofilament slowly absorbable (Correct answer)
- Silk (braided, non-absorbable)
- Chromic gut (rapidly absorbable)
- Polyester braided suture (Ethibond)
Correct answer: Polydioxanone (PDS) — monofilament slowly absorbable
Monofilament slowly absorbable sutures like PDS are preferred in contaminated wounds because they provide prolonged tensile strength and their monofilament structure harbors fewer bacteria than braided sutures.
Question 119: Which CCI credential specifically designates competency as a registered nurse first assistant in the perioperative setting?
- CNOR
- CPSN
- CSSM
- CRNFA (Correct answer)
Correct answer: CRNFA
The CRNFA (Certified Registered Nurse First Assistant) is the specific CCI credential recognizing competency in the RN first assistant role.
Question 120: Negative pressure wound therapy (NPWT/VAC) promotes wound healing primarily by which mechanisms?
- Providing mechanical compression to reduce wound size
- Removing exudate, reducing edema, promoting granulation tissue, and increasing local blood flow (Correct answer)
- Delivering topical antibiotics to the wound bed
- Providing a dry wound environment and preventing contamination only
Correct answer: Removing exudate, reducing edema, promoting granulation tissue, and increasing local blood flow
NPWT promotes healing by removing excess wound fluid, reducing interstitial edema, stimulating granulation tissue formation, and increasing local tissue perfusion.
Question 121: Intraoperative hypothermia (core temperature < 36°C) increases the risk of which complication most significantly?
- Pulmonary embolism
- Hyperglycemia
- Surgical site infection and coagulopathy (Correct answer)
- Postoperative nausea and vomiting
Correct answer: Surgical site infection and coagulopathy
Hypothermia impairs neutrophil oxidative killing, causes vasoconstriction reducing tissue oxygenation, and inhibits coagulation enzyme function, tripling SSI risk and promoting coagulopathy.
Question 122: According to AORN standards, how should the RNFA handle a needlestick injury sustained during surgery?
- Notify the surgeon only if bleeding occurs at the puncture site
- Stop, remove gloves, wash the wound, and report per institutional protocol immediately (Correct answer)
- Apply a new glove over the punctured glove and continue
- Continue the procedure and report the injury after surgery is complete
Correct answer: Stop, remove gloves, wash the wound, and report per institutional protocol immediately
AORN mandates immediate wound care and incident reporting following any sharps injury to protect the healthcare worker and ensure proper follow-up.
Question 123: When handling instruments that have been exposed to Creutzfeldt-Jakob disease (CJD) prions, standard sterilization with steam autoclave is:
- Sufficient if a full prevacuum cycle is used
- Sufficient when combined with glutaraldehyde soaking
- Insufficient; prions require specialized decontamination protocols (Correct answer)
- Sufficient only if high-temperature 273°F (134°C) cycles are doubled
Correct answer: Insufficient; prions require specialized decontamination protocols
Prions are not inactivated by standard steam sterilization or chemical disinfectants; WHO and CDC recommend instrument destruction or highly specialized alkaline/autoclaving protocols.
Question 124: A hospital requires all surgical nurses to hold specialty certification. A newly hired RN first assistant has 3 years of RNFA experience but no current CNOR. What is the first step this nurse should take according to CCI requirements?
- Contact AORN for a letter of support to bypass CCI's CNOR rule
- Obtain and maintain an active CNOR certification before pursuing CRNFA (Correct answer)
- Apply directly for the CRNFA exam citing years of experience
- Submit a variance request to CCI to waive the CNOR prerequisite
Correct answer: Obtain and maintain an active CNOR certification before pursuing CRNFA
CCI mandates a current CNOR as a prerequisite for CRNFA eligibility; years of experience alone do not substitute for this foundational credential.
Question 125: Which of the following does the hospital or medical staff have the least influence over?
- Patient's health condition (Correct answer)
- Surgical technique
- Skin preparation
- Instrument processing
Correct answer: Patient's health condition
While hospitals and medical staff strive to improve a patient's health condition through treatment and care, they have the least direct influence over the patient's pre-existing health status, chronic diseases, genetic predispositions, and lifestyle choices that contribute to their overall health. Surgical technique, instrument processing, and skin preparation are all direct aspects of care delivery that are entirely within the control and influence of the medical staff and hospital protocols.
Question 126: When the RNFA performs tissue retraction during surgery, AORN guidelines emphasize which primary consideration?
- Retractor placement is solely the surgeon's responsibility, not the RNFA's
- Using the least amount of pressure necessary to avoid ischemia and nerve injury (Correct answer)
- Retraction time is irrelevant as long as the surgical field is visible
- Applying maximum retraction force to optimize the surgeon's exposure
Correct answer: Using the least amount of pressure necessary to avoid ischemia and nerve injury
AORN's first assistant guidelines stress minimizing retraction pressure and duration to prevent pressure-related tissue ischemia and nerve damage.
Question 127: The CRNFA is assisting with a laparoscopic Nissen fundoplication. The surgeon asks for more visualization of the gastroesophageal junction. The most appropriate first-assistant action is:
- Ask the anesthesiologist to deflate the stomach with an NG tube
- Increase the CO2 insufflation pressure above 20 mmHg
- Request the patient be placed in steep reverse Trendelenburg
- Reposition the liver retractor to improve cephalad exposure (Correct answer)
Correct answer: Reposition the liver retractor to improve cephalad exposure
Adjusting the liver retractor to elevate the left lobe of the liver is the direct and immediate method to expose the gastroesophageal junction during laparoscopic fundoplication.

The celiac trunk trifurcates into the left gastric artery, splenic artery, and common hepatic artery to supply the foregut structures.
Question 129: Wound dehiscence involving complete separation of all tissue layers with bowel protruding is termed what, and what is the immediate nursing action?
- Evisceration; cover with a sterile saline-moistened dressing and notify surgeon immediately (Correct answer)
- Seroma; aspirate fluid and apply pressure dressing
- Fistula formation; apply wound drainage bag
- Dehiscence; apply an abdominal binder and monitor
Correct answer: Evisceration; cover with a sterile saline-moistened dressing and notify surgeon immediately
Evisceration is the life-threatening protrusion of abdominal contents through a wound; the immediate action is to cover with sterile saline-moistened gauze and emergently notify the surgeon for return to OR.
Question 130: The CRNFA identifies a Metzenbaum scissors on the instrument table. Its PRIMARY use is for:
- Opening skin incisions
- Cutting suture material
- Cutting heavy fascia and tissue
- Dissecting delicate tissue (Correct answer)
Correct answer: Dissecting delicate tissue
Metzenbaum scissors have long, slender blades designed for dissecting and cutting delicate tissue, not for cutting suture.
Question 131: A hospital's credentialing committee asks whether CRNFA certification is equivalent to physician assistant surgical training. The most accurate response is:
- Yes; both credentials are awarded by CCI and carry identical hospital privileges
- Yes; the CRNFA credential is legally equivalent to a PA-C for surgical privileges
- No; the CRNFA is a lower-level credential requiring only 6 months of experience
- No; the CRNFA certifies perioperative nursing competency in the RNFA role, governed by nursing scope of practice (Correct answer)
Correct answer: No; the CRNFA certifies perioperative nursing competency in the RNFA role, governed by nursing scope of practice
The CRNFA credential validates specialized perioperative nursing competency within the RN scope of practice and is distinct from PA-C training and scope.
Question 132: Which of the following best illustrates the concept of 'competency' as CCI applies it to the CRNFA credential?
- Accumulation of the highest number of CE hours among perioperative nurses
- The ability to perform any surgical procedure independently without supervision
- Completion of a bachelor's degree in nursing as the minimum academic standard
- Demonstrated knowledge, skills, and judgment sufficient to safely perform the RNFA role (Correct answer)
Correct answer: Demonstrated knowledge, skills, and judgment sufficient to safely perform the RNFA role
CCI defines competency as the integration of knowledge, skills, and clinical judgment needed to safely and effectively perform the RNFA role in perioperative care.
Question 133: Which of the following correctly describes the relationship between AORN and CCI regarding the CRNFA credential?
- CCI is the credentialing body; AORN provides the educational framework and advocacy (Correct answer)
- AORN administers the exam; CCI sets eligibility
- AORN grants the credential after CCI approves eligibility
- They are the same organization operating under different names
Correct answer: CCI is the credentialing body; AORN provides the educational framework and advocacy
CCI is the independent credentialing organization that administers and grants the CRNFA, while AORN provides the professional standards and educational support.
Question 134: A CRNFA whose certification has lapsed for more than 2 years must complete which of the following to reinstate the credential through CCI?
- Submit a late renewal fee only
- Reapply through AORN rather than CCI
- Retake the full CRNFA examination (Correct answer)
- Complete 40 CEUs and pay a reinstatement fee
Correct answer: Retake the full CRNFA examination
If the CRNFA credential has been inactive for more than 2 years, the nurse must retake and pass the CRNFA certification examination to regain the credential.
Question 135: AORN recommends that the RNFA demonstrate competency in first assistant skills through which mechanism?
- Annual competency validation and continuing education (Correct answer)
- Verbal confirmation of skills by the surgeon on record
- Peer observation only, without formal documentation
- One-time certification upon hire with no further validation
Correct answer: Annual competency validation and continuing education
AORN requires ongoing competency validation through annual assessments and continuing education to ensure safe practice.
Question 136: Which of the following best describes the principle of 'gravity displacement' (downward displacement) steam sterilization?
- Steam enters from above, pushing air downward and out through the drain (Correct answer)
- Steam enters from below, displacing air upward and out through the drain
- A vacuum removes air before steam enters the chamber
- Steam and ethylene oxide are used simultaneously to displace air
Correct answer: Steam enters from above, pushing air downward and out through the drain
In gravity displacement sterilization, steam enters at the top of the chamber and, being lighter than air, pushes air downward and out through the drain at the bottom.
Question 137: AORN's recommended practice for surgical smoke evacuation requires that smoke plumes be evacuated because they:
- Are regulated only for cosmetic surgery procedures
- Contain viable cellular material, carcinogens, and infectious particles (Correct answer)
- Only create a visual obstruction with no known health hazards
- Are primarily composed of water vapor with minimal particulate matter
Correct answer: Contain viable cellular material, carcinogens, and infectious particles
AORN has documented that surgical smoke contains mutagenic and carcinogenic compounds, viable viral and bacterial particles, and requires evacuation to protect OR personnel.
Question 138: A DeBakey tissue forceps is preferred over Adson tissue forceps when handling which type of tissue?
- Delicate vascular or bowel tissue (Correct answer)
- Dense fibrous fascia
- Subcutaneous adipose tissue
- Skin edges during closure
Correct answer: Delicate vascular or bowel tissue
DeBakey forceps have atraumatic fine serrations that grip delicate vascular or intestinal tissue without crushing, unlike the toothed Adson forceps.
Question 139: What nerve damage following thyroid surgery would cause hoarseness?
- Recurrent laryngeal (Correct answer)
- Interior laryngeal
- Direct hernia
- Phrenic nerve
Correct answer: Recurrent laryngeal
The recurrent laryngeal nerve innervates most of the intrinsic muscles of the larynx, which are responsible for vocal cord movement. During thyroid surgery, this nerve is vulnerable to injury due to its close anatomical relationship with the thyroid gland. Damage to the recurrent laryngeal nerve can lead to vocal cord paralysis, resulting in symptoms such as hoarseness, dysphonia, or even difficulty breathing.
Question 140: A patient on therapeutic anticoagulation with warfarin undergoes emergency surgery. Intraoperatively, the CRNFA observes persistent oozing from tissue planes. Which agent is most appropriate to request for pharmacologic hemostasis?
- Fresh frozen plasma (FFP) (Correct answer)
- Aminocaproic acid (Amicar)
- Protamine sulfate
- Tranexamic acid
Correct answer: Fresh frozen plasma (FFP)
Fresh frozen plasma contains all clotting factors and is the preferred reversal agent for warfarin-induced coagulopathy in emergency surgery.
Question 141: Which documentation is the CRNFA responsible for ensuring is complete before the surgical incision is made?
- Discharge instructions
- Postoperative pain management orders
- Insurance preauthorization
- Signed and witnessed surgical informed consent on the chart (Correct answer)
Correct answer: Signed and witnessed surgical informed consent on the chart
Verifying that signed informed surgical consent is present on the chart is a mandatory preoperative safety check performed during the timeout and pre-incision phase.
Question 142: AORN's Guideline for Transmission-Based Precautions in the Perioperative Setting recommends that the RNFA wear which PPE when operating on a patient with active pulmonary tuberculosis?
- Standard surgical mask, gown, and gloves only
- N95 or higher respirator, gown, gloves, and eye protection (Correct answer)
- No additional PPE beyond standard sterile attire is required
- Face shield alone is sufficient for airborne precautions
Correct answer: N95 or higher respirator, gown, gloves, and eye protection
AORN aligns with CDC airborne precaution requirements, mandating an N95 or higher respirator for procedures involving patients with active TB.
Question 143: A patient with a known latex allergy is scheduled for surgery. The CRNFA should verify that which item is replaced with a latex-free alternative?
- Cautery pencil holster
- Electrosurgical dispersive electrode cable
- Foley catheter and drainage tubing (Correct answer)
- Stainless steel retractors
Correct answer: Foley catheter and drainage tubing
Foley catheters and drainage tubing traditionally contain latex and must be substituted with latex-free alternatives in sensitized patients.
Question 144: AORN guidelines on specimen management require the RNFA to:
- Document specimen collection only in the postoperative nursing note
- Allow the pathology department to label specimens upon receipt
- Label all specimens immediately at the sterile field and verify with the circulator before transfer (Correct answer)
- Place all specimens in a shared container to be sorted after the procedure
Correct answer: Label all specimens immediately at the sterile field and verify with the circulator before transfer
AORN requires immediate, accurate labeling and two-person verification of surgical specimens to prevent identification errors.
Question 145: When managing a patient with a known malignant hyperthermia (MH) susceptibility, AORN recommends that the RNFA ensure:
- A dantrolene kit is immediately available and triggering agents are avoided (Correct answer)
- Room temperature is maintained below 60°F to prevent hyperthermia
- Succinylcholine is administered prophylactically to prevent MH
- The procedure is performed only under local anesthesia regardless of surgical needs
Correct answer: A dantrolene kit is immediately available and triggering agents are avoided
AORN's MH guidelines require avoidance of triggering agents and immediate availability of dantrolene for any MH-susceptible patient.
Question 146: During laparoscopic cholecystectomy, critical view of safety requires visualization of how many structures entering the gallbladder?
- One structure (cystic duct)
- Two structures (cystic duct and cystic artery) (Correct answer)
- The gallbladder neck and hepatocystic triangle only
- Three structures including the common bile duct
Correct answer: Two structures (cystic duct and cystic artery)
Critical view of safety requires that only two structures — the cystic duct and cystic artery — are seen entering the gallbladder before clipping.
Question 147: Under CCI guidelines, which activity would NOT be accepted as valid continuing education for CRNFA renewal?
- Presenting a case study at a hospital-based perioperative in-service
- Attending an AORN Congress session on surgical techniques
- Completing a CCI-approved online perioperative module
- Taking a general wellness course unrelated to perioperative practice (Correct answer)
Correct answer: Taking a general wellness course unrelated to perioperative practice
CCI requires that CE hours be relevant to perioperative nursing practice; a general wellness course with no perioperative application would not qualify.
Question 148: When using a harmonic scalpel (ultrasonic energy device), what is the primary mechanism of tissue sealing?
- Radiofrequency energy at 300 kHz
- Thermal conduction from the active blade only
- Mechanical vibration denaturing protein to form a coagulum (Correct answer)
- Electrical coagulation of proteins
Correct answer: Mechanical vibration denaturing protein to form a coagulum
The harmonic scalpel uses high-frequency mechanical vibration (55,500 Hz) to denature protein and form a coagulative seal without electrical current passing through the patient.
Question 149: A patient undergoing elective hip replacement has a preoperative hemoglobin of 9.5 g/dL. The CRNFA's most appropriate action is to:
- Proceed without concern as this is within normal limits
- Cancel the surgery without consulting the surgeon
- Administer iron supplementation per standing order
- Notify the surgeon and anesthesiologist and document the finding (Correct answer)
Correct answer: Notify the surgeon and anesthesiologist and document the finding
A hemoglobin of 9.5 g/dL represents anemia that increases transfusion risk; the CRNFA should notify the surgeon and anesthesiologist so they can decide whether to proceed or optimize the patient.
Question 150: During a video-assisted thoracoscopic surgery (VATS) lobectomy, the patient's oxygen saturation suddenly drops and breath sounds disappear on the operative side. The CRNFA should first suspect:
- CO2 embolism from thoracoscopic port insufflation
- Tension pneumothorax on the contralateral side
- Pulmonary artery injury with hemorrhage
- Endobronchial tube migration causing single-lung ventilation failure (Correct answer)
Correct answer: Endobronchial tube migration causing single-lung ventilation failure
Double-lumen endobronchial tube migration can cause loss of lung isolation and ventilation failure, and is a common cause of sudden desaturation in VATS procedures.
Question 151: According to AORN's Guideline for Hand Hygiene, alcohol-based hand rub is NOT appropriate before the surgical hand antisepsis if the hands are:
- Being prepared for a second consecutive procedure
- Visibly soiled or contaminated with blood or body fluids (Correct answer)
- Dry from frequent handwashing earlier in the shift
- Exposed to non-sterile equipment in the scrub area
Correct answer: Visibly soiled or contaminated with blood or body fluids
AORN and CDC guidelines require soap-and-water handwashing when hands are visibly soiled before performing surgical hand antisepsis.
Question 152: Which of the following constructions should be avoided and an early identification made during TAH?
- Liver
- Colostomy
- Ureters (Correct answer)
- Cervix
Correct answer: Ureters
During a Total Abdominal Hysterectomy (TAH), the ureters are in close proximity to the uterus and its vascular supply. Accidental ligation, transection, or kinking of the ureters is a serious complication that can lead to hydronephrosis, kidney damage, or even renal failure. Therefore, early identification and careful dissection to avoid injury to the ureters are crucial for patient safety and preventing severe postoperative complications.
Question 153: When ligating a vessel with a free tie, the CRNFA should ensure the ligature is placed:
- Distal to the anticipated division point only
- At the midpoint of the vessel segment to be removed
- Exactly at the cut end of the vessel for maximum security
- Proximal to the cut end with enough tissue to prevent slippage (Correct answer)
Correct answer: Proximal to the cut end with enough tissue to prevent slippage
A free tie placed proximal to the cut end with adequate tissue ensures the ligature cannot slip off the vessel stump.
Question 154: When applying electrosurgical coagulation to a bleeding vessel, the CRNFA should use which technique for optimal hemostasis?
- Use the coagulation setting at maximum power for all vessels
- Apply the electrode directly to the vessel while activating for 10 seconds
- Activate the electrode in the air near the bleeding point
- Grasp the vessel with forceps and touch the active electrode to the forceps briefly (Correct answer)
Correct answer: Grasp the vessel with forceps and touch the active electrode to the forceps briefly
Coaptive coagulation — grasping the vessel with metal forceps and briefly touching the active electrode to the forceps — concentrates energy at the vessel and produces reliable hemostasis.
Question 155: During fascial closure of a midline laparotomy, the CRNFA uses a running Smead-Jones suture technique. What is the primary advantage of this technique?
- It allows for complete wound exploration if infection occurs
- It avoids the need for retention sutures in obese patients
- It is faster and uses less suture material than interrupted closure
- It distributes tension across a wide fascial bite to reduce dehiscence risk (Correct answer)
Correct answer: It distributes tension across a wide fascial bite to reduce dehiscence risk
The Smead-Jones far-near near-far technique incorporates a wide fascial bite that distributes closure tension and significantly reduces dehiscence rates.
Question 156: A CRNFA discovers her certification expired 14 months ago due to an administrative oversight. According to CCI policy, she should:
- Retake the CRNFA exam immediately as the lapse exceeds 12 months
- Wait until the next biennial testing window to reapply
- Apply for late renewal; the lapse is under 2 years so reinstatement without retesting may be possible (Correct answer)
- Contact AORN to restore her certification through their registry
Correct answer: Apply for late renewal; the lapse is under 2 years so reinstatement without retesting may be possible
CCI typically allows late reinstatement within a 2-year lapse window with fees and CE documentation, without requiring retesting.
Question 157: The saphenous vein joins which vessel in the femoral triangle?
- Femoral artery
- Femoral vein (Correct answer)
- External iliac vein
- Popliteal vein
Correct answer: Femoral vein
The great saphenous vein drains into the femoral vein at the saphenofemoral junction, which is ligated during vein stripping procedures.
Question 158: Which vessel-sealing device uses bipolar energy combined with pressure to create a permanent seal on vessels up to 7 mm in diameter?
- LigaSure (Correct answer)
- Argon beam coagulator
- Monopolar ESU pencil
- Harmonic scalpel
Correct answer: LigaSure
LigaSure uses bipolar radiofrequency energy and mechanical pressure to denature collagen and elastin, creating a permanent seal on vessels up to 7 mm.
Question 159: According to AORN, the role of the RNFA during the postoperative phase includes which of the following?
- Writing postoperative orders within the RNFA's credentialed scope, applying wound dressings, and providing patient education (Correct answer)
- Performing postoperative imaging interpretation as the primary radiologic reader
- Independently discharging the patient from the facility without physician oversight
- Administering anesthesia reversal agents independently in the PACU
Correct answer: Writing postoperative orders within the RNFA's credentialed scope, applying wound dressings, and providing patient education
AORN recognizes the RNFA's postoperative role as including wound care, patient education, and order writing within their legally authorized and credentialed scope.
Question 160: A fire has started on the sterile drape from an ESU spark near supplemental oxygen. The CRNFA's immediate priority is to:
- Activate the fire extinguisher immediately over the patient
- Evacuate the OR immediately
- Remove the burning drape from the patient, stop oxygen flow, and extinguish the fire away from the patient (Correct answer)
- Call for the fire department only
Correct answer: Remove the burning drape from the patient, stop oxygen flow, and extinguish the fire away from the patient
The RACE/PASS OR fire response prioritizes removing the burning material from the patient and cutting off the oxygen supply (the oxidizer) before using an extinguisher away from the patient's airway.
Question 161: The uterus's upper, dome-like section is referred to as the?
- Fundus (Correct answer)
- Pylorus
- Cervix
- Reticulum
Correct answer: Fundus
The fundus is the uppermost, rounded part of the uterus, situated superior to the entrance of the fallopian tubes. This region is significant as it is where the uterine wall is thickest and where implantation typically occurs during pregnancy. Its position and size are often assessed during obstetric examinations to determine uterine growth and fetal development.
Question 162: The CCI CRNFA exam uses which type of scoring standard to determine passing status?
- Criterion-referenced scoring based on a predetermined passing standard (Correct answer)
- Norm-referenced scoring (top 70% of test takers pass)
- Pass/fail determined solely by the number of correct answers with no psychometric standard
- A curved score relative to the national average for that testing window
Correct answer: Criterion-referenced scoring based on a predetermined passing standard
CCI uses criterion-referenced scoring, meaning the passing standard is set based on the minimum competency level required, not relative to other candidates' performance.
Question 163: A retention (stay) suture is used in abdominal closure primarily for which purpose?
- To secure drains in place
- Cosmetic skin closure
- To add supplemental strength in high-risk patients prone to dehiscence (Correct answer)
- To approximate subcutaneous fat only
Correct answer: To add supplemental strength in high-risk patients prone to dehiscence
Retention sutures are large, through-and-through sutures placed to provide additional fascial support in obese, malnourished, or immunocompromised patients at high risk for wound dehiscence.
Question 164: Which layer of the abdominal wall is the deepest and must be closed separately during abdominal surgery?
- Subcutaneous fascia
- Scarpa's fascia
- Transversalis fascia (Correct answer)
- External oblique aponeurosis
Correct answer: Transversalis fascia
The transversalis fascia is the deepest layer of the abdominal wall and requires separate closure to prevent hernia formation.
Question 165: During a laparoscopic procedure, the CRNFA notices the laparoscope image is foggy. The MOST appropriate initial action is to:
- Increase the light source intensity to maximum
- Reduce insufflation pressure to improve visualization
- Clean the laparoscope lens with a warm, moist sponge or anti-fog solution (Correct answer)
- Replace the entire laparoscope immediately
Correct answer: Clean the laparoscope lens with a warm, moist sponge or anti-fog solution
Fogging occurs when the cold lens contacts warm, moist tissue; warming or wiping the lens with an anti-fog solution is the standard first corrective step.
Question 166: For CRNFA renewal, CCI allows candidates to demonstrate continued competency through what alternative to accumulating 20 CE hours?
- Completing a CCI-sponsored simulation lab
- Retaking and passing the CRNFA examination (Correct answer)
- Submitting a peer evaluation form signed by two surgeons
- Publishing a peer-reviewed article on surgical assistance
Correct answer: Retaking and passing the CRNFA examination
Retaking and passing the CRNFA exam is an accepted alternative pathway for renewal, demonstrating current knowledge competency in lieu of CE hours.
Question 167: The CRNFA observes sudden masseter muscle rigidity after succinylcholine administration during intubation. This finding should prompt concern for which emergent condition?
- Anaphylaxis
- Laryngospasm
- Malignant hyperthermia (Correct answer)
- Insufficient neuromuscular blockade
Correct answer: Malignant hyperthermia
Masseter muscle rigidity (jaw rigidity) following succinylcholine is an early and classic warning sign of malignant hyperthermia and requires immediate activation of the MH protocol.
Question 168: According to AORN guidelines, which action is the RNFA's primary responsibility when managing intraoperative bleeding?
- Apply direct pressure and use hemostatic agents as directed by the surgeon (Correct answer)
- Order packed red blood cells without surgeon consultation
- Administer IV fluids independently to compensate for blood loss
- Document blood loss only after the procedure is complete
Correct answer: Apply direct pressure and use hemostatic agents as directed by the surgeon
The RNFA assists in hemostasis by applying pressure and using hemostatic agents under the surgeon's direction, consistent with AORN first assistant scope.
Question 169: The CRNFA observes that a patient's wound is producing green malodorous drainage 5 days postoperatively. The most likely causative organism is:
- Streptococcus pyogenes (thin, watery discharge)
- Anaerobic bacteria (brownish discharge with feculent odor)
- Pseudomonas aeruginosa (green/blue-green exudate with fruity odor) (Correct answer)
- Staphylococcus aureus (golden yellow exudate)
Correct answer: Pseudomonas aeruginosa (green/blue-green exudate with fruity odor)
Pseudomonas aeruginosa characteristically produces blue-green (pyocyanin) pigmented, malodorous wound exudate and is associated with moist wound environments.
Question 170: When completing the CRNFA application, which documentation must accompany proof of RNFA formal education?
- A transcript from an accredited nursing school showing surgical rotation grades
- Evidence of CPSN certification as a supplemental credential
- A letter of recommendation from the applicant's OR manager
- A surgeon attestation letter confirming the applicant's first-assisting competency and hours (Correct answer)
Correct answer: A surgeon attestation letter confirming the applicant's first-assisting competency and hours
CCI requires an attestation from a supervising surgeon or qualified healthcare professional verifying the applicant's first-assisting clinical hours.
Question 171: Which component of the preoperative assessment is specifically within the CRNFA's scope when functioning as first assistant?
- Performing a focused preoperative nursing assessment and assisting with history and physical (Correct answer)
- Obtaining informed surgical consent as the primary provider
- Ordering and interpreting preoperative labs independently
- Administering preanesthetic medications independently
Correct answer: Performing a focused preoperative nursing assessment and assisting with history and physical
The CRNFA performs a focused preoperative nursing assessment and collaborates with the surgical and anesthesia team — independently ordering labs or obtaining surgical consent is outside CRNFA scope in most states.
Question 172: The Triangle of Calot is bounded by which structures?
- Cystic duct, portal vein, hepatic artery
- Cystic duct, common hepatic duct, liver edge (Correct answer)
- Liver, cystic artery, common bile duct
- Liver, cystic duct, hepatic duct
Correct answer: Cystic duct, common hepatic duct, liver edge
The Triangle of Calot is defined by the cystic duct inferiorly, the common hepatic duct medially, and the liver edge superiorly, and contains the cystic artery.
Question 173: Which AORN document provides the foundational framework for perioperative nursing practice standards?
- The Joint Commission Comprehensive Accreditation Manual only
- The Nurse Practice Act published annually by AORN
- Perioperative Nursing Data Set (PNDS) and Standards of Perioperative Nursing (Correct answer)
- Centers for Medicare & Medicaid Services Conditions of Participation exclusively
Correct answer: Perioperative Nursing Data Set (PNDS) and Standards of Perioperative Nursing
The PNDS and AORN's Standards of Perioperative Nursing define the data elements and standards that guide evidence-based perioperative nursing practice.
Question 174: During closure, the CRNFA should verify that drains are placed in which location relative to the primary incision?
- As close to the incision as possible for stability
- Directly through the incision line to reduce total skin wounds
- Through a separate stab incision away from the primary wound to prevent contamination of the healing incision (Correct answer)
- Placement location does not affect wound outcomes
Correct answer: Through a separate stab incision away from the primary wound to prevent contamination of the healing incision
Drains should exit through a separate stab wound to prevent the drain tract from contaminating the primary incision and to avoid weakening the primary closure.
Question 175: Which blood supply to the sigmoid colon is most commonly divided during sigmoid colectomy?
- Middle colic artery
- Inferior mesenteric artery branches (sigmoid arteries) (Correct answer)
- Superior rectal artery only
- Right colic artery
Correct answer: Inferior mesenteric artery branches (sigmoid arteries)
The sigmoid colon is supplied by sigmoid arteries (sigmoidal branches of the inferior mesenteric artery) which are divided during sigmoid colectomy.
Question 176: Microfibrillar collagen hemostats (e.g., Avitene) work by which mechanism?
- Providing thrombin exogenously
- Converting fibrinogen to fibrin chemically
- Physically tamponading vessels with a wax matrix
- Activating the intrinsic pathway by attracting and aggregating platelets on collagen fibers (Correct answer)
Correct answer: Activating the intrinsic pathway by attracting and aggregating platelets on collagen fibers
Microfibrillar collagen attracts and aggregates platelets on its surface, activating the intrinsic clotting cascade and forming a platelet plug reinforced by fibrin.
Question 177: Which of the following most accurately describes the CRNFA examination's content blueprint as defined by CCI's practice analysis?
- Domains derived from a task analysis of actual RNFA perioperative practice (Correct answer)
- Standardized using the NCLEX-RN blueprint as a base
- Equal weighting across anatomy, pharmacology, and law
- Developed solely by AORN without CCI input
Correct answer: Domains derived from a task analysis of actual RNFA perioperative practice
CCI conducts periodic role delineation studies (practice analyses) to identify the actual tasks RNFAs perform, then weights exam content accordingly.
Question 178: Which AORN-recommended practice describes the appropriate management of a sharps container that reaches the fill line in the OR during an ongoing procedure?
- Seal the container and replace it with a new one without interrupting the sterile field (Correct answer)
- Continue adding sharps above the fill line until the procedure is complete
- Pass the overfilled container to the sterile field for temporary storage
- Manually compress the contents to create space for additional sharps
Correct answer: Seal the container and replace it with a new one without interrupting the sterile field
AORN's sharps safety guidelines require replacing a full sharps container immediately to prevent needlestick injuries from overfilling.
Question 179: A patient discloses herbal supplement use including garlic, ginger, and Ginkgo biloba. The CRNFA's primary concern is which potential intraoperative complication?
- Renal failure
- Hypertensive crisis
- Increased bleeding due to antiplatelet effects of these supplements (Correct answer)
- Malignant hyperthermia
Correct answer: Increased bleeding due to antiplatelet effects of these supplements
Garlic, ginger, and Ginkgo biloba all have antiplatelet properties that can increase intraoperative and postoperative bleeding risk.
Question 180: The greatest tensile strength of a wound scar compared to original tissue is approximately what percentage at full maturation?
- 80% (Correct answer)
- 25%
- 100% — fully restored
- 50%
Correct answer: 80%
A mature scar achieves approximately 80% of the original tissue tensile strength due to reorganization of collagen fibers, but never fully equals normal tissue.
Question 181: The sphincter of Oddi controls flow at the junction of which structures?
- Common bile duct and pancreatic duct at the ampulla of Vater (Correct answer)
- Cystic duct and common bile duct
- Gallbladder and cystic duct
- Pancreatic duct and duodenum separately
