All questions

Question 1

A 76-year-old client with type 2 diabetes mellitus has a surgical wound with moderate drainage requiring a sterile dressing change. After opening the sterile dressing kit, the RN realizes the client's call light is out of reach and the client is anxious. Which action by the nurse maintains sterility?

  1. Ask the client to hold still while the RN steps away briefly, leaving the sterile field unattended
  2. Ask assistive personnel to reposition the call light while the RN remains at the sterile field
  3. Remove sterile gloves, adjust the call light, then don new sterile gloves and continue with the same sterile field
  4. Continue the dressing change and address the call light after the sterile dressing is applied (correct answer)
Explanation: This question tests the maintenance of sterile technique and sterile field for wound dressing changes. Critical principles include never leaving a sterile field unattended and prioritizing completion over non-urgent interruptions. Continuing the dressing change and addressing the call light after maintains sterility by avoiding abandonment or unnecessary glove changes. Stepping away, delegating, or removing gloves risks contamination. The foundational principle of sterile technique requires constant supervision of the field. Interruptions should be minimized. In practice, prepare the environment beforehand to avoid disruptions during sterile procedures.

Question 2

A 47-year-old client with acute respiratory distress syndrome requires a central line insertion. The RN is performing an infection control audit and observes the following steps by a nurse assisting with the procedure. Which observation indicates a breach in sterile technique?

  1. The assisting nurse wears a mask, cap, sterile gown, and sterile gloves
  2. The assisting nurse places sterile ultrasound gel on the probe after applying a sterile probe cover
  3. The assisting nurse reaches over the sterile field to plug in a nonsterile device (correct answer)
  4. The assisting nurse maintains the sterile field at or above waist level
Explanation: This question tests the maintenance of sterile technique and sterile field during central line insertion. Critical principles include avoiding reaching over the field with non-sterile actions. Reaching over to plug in a device breaches sterility by risking airborne or contact contamination. Wearing full PPE, placing gel after cover, and maintaining level are correct. The foundational principle of sterile technique prohibits non-sterile movements over sterile areas. Such actions introduce risks. In practice, position equipment beforehand to avoid reaching during procedures.

Question 3

A 56-year-old client is in the operating room for a cholecystectomy and has a history of asthma. The circulating nurse observes the sterile back table has been set up, but the room door is repeatedly opened by staff entering to ask questions. Which action by the nurse is BEST to maintain the sterile field?

  1. Ask staff to minimize door openings and keep traffic in and out of the room to a minimum (correct answer)
  2. Place a clean sheet over the sterile back table and continue allowing door openings for staff to ask questions
  3. Ask the scrub nurse to turn away from the sterile field when the door opens to block air currents
  4. Increase the room temperature to reduce airborne contamination risk by making particles settle out of the air faster
Explanation: To maintain a sterile field, the most effective action is to minimize door openings and restrict traffic because air currents from door movement and personnel entry are the leading cause of airborne contamination. Placing a clean sheet over the sterile back table does not stop airborne particles from settling on exposed instruments, and it does not reduce the turbulence created by staff entering and exiting. Asking the scrub nurse to turn away from the field when the door opens does not block air currents from carrying particles onto the table; it only changes the nurse's position and may even increase the risk of accidental contact. Increasing the room temperature does not reduce airborne contamination; warmer air produces stronger convection currents that can lift and disperse particles, and it ignores the underlying problem of traffic. Thus, limiting traffic is the best way to protect the sterile field.

Question 4

A 70-year-old client with a history of recurrent urinary tract infections requires a Foley catheter insertion. The RN is preparing the sterile field and notices the sterile catheter package is intact but the expiration date was 2 months ago. Which action by the nurse maintains sterility?

  1. Use the catheter because the package is unopened and appears intact
  2. Discard the catheter and obtain an unexpired sterile catheter before proceeding (correct answer)
  3. Soak the catheter in antiseptic solution to compensate for expiration
  4. Proceed and document the expiration date after the catheter is inserted
Explanation: This question tests the maintenance of sterile technique and sterile field for catheter insertion. Critical principles include using only unexpired sterile items to ensure integrity and efficacy. Discarding the expired catheter and obtaining a new one maintains sterility as expiration compromises packaging. Using it, soaking, or documenting ignores risks. The foundational principle of sterile technique relies on manufacturer guarantees until expiration. Post-expiration assumes loss of sterility. In practice, always check dates before opening and replace expired items immediately.

Question 5

A 40-year-old client with a history of intravenous drug use is admitted with infective endocarditis and requires a central line insertion. During the procedure, the RN observes the sterile drape has a small tear near the edge. Which action by the nurse maintains sterility?

  1. Cover the tear with a piece of sterile gauze and continue
  2. Replace the torn drape with a new sterile drape before proceeding (correct answer)
  3. Ignore the tear because it is near the edge of the drape
  4. Apply additional skin antiseptic to compensate for the tear
Explanation: This question tests the maintenance of sterile technique and sterile field during central line insertion. Critical principles include using intact drapes to create a barrier, replacing any compromised ones. Replacing the torn drape maintains sterility by ensuring an unbroken barrier against contamination. Covering, ignoring, or compensating with antiseptic does not restore integrity. The foundational principle of sterile technique is that drapes must be impermeable and intact. Tears allow pathogen passage. In practice, inspect drapes before and during use, replacing immediately if damaged.

Question 6

A 45-year-old client is in the operating room for an open appendectomy with a history of obesity and hypertension. The circulating nurse observes the sterile team preparing for incision. Which observation indicates a breach in sterile technique?

  1. A sterile team member turns their back to the sterile field while adjusting their mask (correct answer)
  2. The scrub nurse keeps sterile hands above waist level and in view
  3. Sterile drapes are applied from the incision site outward
  4. The circulating nurse remains outside the sterile field while documenting
Explanation: This question tests the maintenance of sterile technique and sterile field in the operating room. Critical principles include keeping the back to the sterile field avoided to prevent unseen contamination and maintaining constant vigilance. A sterile team member turning their back to the field breaches sterility by risking airborne or contact contamination without monitoring. Keeping hands above waist, draping outward, and circulating nurse staying outside are all correct practices. The foundational principle of sterile technique is constant visual monitoring to ensure no breaches occur. Any lapse in oversight can introduce pathogens. In practice, position yourself to always face the sterile field and avoid turning away during procedures.

Question 7

A 33-year-old postpartum client with a third-degree perineal laceration has an order for sterile perineal wound dressing change. The RN prepares the sterile field and pours sterile normal saline into a sterile basin. Which observation indicates a breach in sterile technique?

  1. The RN holds the saline bottle 2.5 cm (1 in) above the sterile basin and pours with a slow, steady stream.
  2. The RN places the sterile basin on the center of the sterile field, leaving the drape's outer border dry and untouched.
  3. The RN allows the saline bottle cap to rest on the sterile field with the inside facing up. (correct answer)
  4. The RN checks the expiration date on the saline bottle and confirms the container's seal is intact before opening it.
Explanation: The breach is the RN allowing the saline bottle cap to rest on the sterile field. Even with the inside of the cap facing up, the cap's rim and outer surface are nonsterile, and any contact with the sterile drape contaminates the field. In sterile technique, a removed cap should be held in the hand or kept off the field, never placed on it. The other observations are proper technique. Holding the bottle 1 inch above the basin while pouring in a slow, steady stream keeps the bottle from touching the sterile basin and limits splash. Placing the basin in the center of the sterile field keeps it within the sterile area and away from the nonsterile outer border. Checking the expiration date and confirming the seal is intact before opening ensures the solution remains sterile. None of these indicate a breach; only the cap touching the sterile field does.

Question 8

A 72-year-old client with peripheral arterial disease and a history of smoking has a large lower-leg ulcer requiring a sterile dressing change. The nurse removes the old dressing and notes moderate serosanguinous drainage and a clean pink wound bed. What should the nurse do FIRST to establish a sterile field for the dressing change?

  1. Don sterile gloves and then open the sterile dressing kit without contaminating the contents
  2. Place the sterile drape on the bedside table after cleaning the table surface (correct answer)
  3. Pour sterile normal saline into a sterile container without splashing on the sterile field
  4. Apply the prescribed sterile dressing to the wound using sterile forceps and gauze
Explanation: To establish a sterile field, the nurse must first create a clean, dry surface and then place the sterile drape on it; this prevents contamination from below before any sterile item is handled or exposed. Putting on sterile gloves and opening the dressing kit first is premature: the field is not yet established, and the gloves and kit can be contaminated by contact with the unprepared bedside surface. Pouring sterile saline into a sterile container is also a later step that depends on having already set up the sterile field; splashing and container placement are managed once the field is in place. Similarly, applying the prescribed sterile dressing with forceps is the final phase of the dressing change; it cannot be the first action because no sterile field exists yet. Only placing the sterile drape on a cleaned bedside table creates the sterile boundary needed before gloves, saline, or dressing are used. The wound bed is clean and pink, so the priority is protecting the field from contamination, not reaching for supplies or dressing the wound first.

Question 9

A 71-year-old client with a history of stroke and neurogenic bladder requires a Foley catheter insertion. The RN has cleansed the urethral meatus using sterile technique and is ready to insert the catheter. Which action by the nurse maintains sterility?

  1. Insert the catheter with the dominant hand after it has touched the bed linen, because bed linen is clean enough.
  2. Keep the sterile hand in the sterile field while the non-dominant hand stabilizes the penis/labia as a contaminated hand (correct answer)
  3. Remove the sterile gloves after cleansing and insert the catheter with clean gloves for better tactile sensation during insertion.
  4. Ask the client to hold the catheter tip to help guide insertion, as this encourages active participation in care.
Explanation: Maintaining a sterile field during catheterization requires clearly separating sterile and non-sterile hands. The correct action is to keep the sterile hand within the field while using the non-dominant hand to stabilize the penis or labia, designating it as contaminated to avoid cross-contamination. Touching the catheter to bed linen introduces contaminants because linen is not sterile. Using clean gloves instead of sterile gloves breaks the sterile barrier. Asking the client to hold the tip risks contamination because the client's hands are not sterile, even though it encourages participation. Thus, only the designated-hand separation preserves sterility.

Question 10

A 59-year-old client with poorly controlled diabetes mellitus is receiving a sterile foot wound dressing change. The RN notes the sterile field was set up on a bedside table, and the client's meal tray is delivered and placed next to the sterile field. Which observation indicates a breach in sterile technique?

  1. The sterile field remains within the RN's view so the RN could monitor it during the dressing change.
  2. Before donning sterile gloves, the RN performs hand hygiene with antiseptic soap for the wound care procedure.
  3. Using sterile forceps, the RN picks up the sterile gauze and places it on the wound bed.
  4. The sterile field is positioned near a nonsterile meal tray that could drip or contact the field. (correct answer)
Explanation: A sterile technique requires keeping the sterile field free of contamination. The sterile field positioned near the nonsterile meal tray is a breach because the tray could drip onto the field or touch it, introducing contaminants. Keeping the sterile field in the RN's view so it can be monitored is appropriate surveillance, not a breach. Performing hand hygiene with antiseptic soap before sterile gloving is correct preparation and does not violate sterility. Using sterile forceps to pick up sterile gauze and place it on the wound bed maintains sterile technique because the forceps and gauze are sterile. Therefore the option involving the nonsterile meal tray is the only one that indicates a breach in sterile technique.

Question 11

A 40-year-old client with multiple sclerosis is admitted for urinary retention and requires an indwelling urinary catheter. During preparation, the nurse opens a sterile catheterization kit on the bedside table. Which action by the nurse maintains sterility during Foley catheter insertion?

  1. Place the sterile catheter tip on the sterile drape while adjusting the light with the same gloved hand
  2. Hold the catheter 2.5 cm (1 inch) from the tip to guide insertion while keeping it above the sterile field
  3. Keep the dominant hand sterile while using the non-dominant hand to separate the labia and maintain that position (correct answer)
  4. Use clean gloves to cleanse the perineum and then proceed without changing gloves
Explanation: This question tests the maintenance of sterile technique and sterile field during urinary catheter insertion. The critical principles include maintaining hand designation (one sterile, one clean) and avoiding cross-contamination during the procedure. Keeping the dominant hand sterile while using the non-dominant hand to separate and maintain the labia (Answer C) correctly maintains sterility by designating specific roles for each hand throughout the procedure. Placing the catheter tip down while adjusting equipment (A) contaminates the catheter, holding near the tip (B) risks contamination of the insertion portion, and using clean gloves throughout (D) fails to maintain the required sterility for catheter insertion. The foundational principle is that designated hand roles prevent cross-contamination between sterile and non-sterile areas. In practice, once hand roles are established during catheterization, they must be maintained throughout the entire procedure.

Question 12

A 29-year-old postpartum client with a history of recurrent urinary tract infections requires a Foley catheter insertion due to urinary retention after delivery. The nurse opens the sterile catheter kit and prepares to don sterile gloves. What should the nurse do FIRST to establish a sterile field and reduce contamination risk?

  1. Position the client in dorsal recumbent position and drape for privacy
  2. Perform hand hygiene and verify that the bedside table surface is clean and dry (correct answer)
  3. Lubricate the catheter tip and place it on the sterile drape
  4. Inflate the catheter balloon with sterile water to test for leaks
Explanation: This question tests the maintenance of sterile technique and sterile field preparation for catheter insertion. The critical principles include ensuring a clean foundation before establishing sterility and following proper procedural sequencing. Performing hand hygiene and verifying the bedside table is clean and dry (Answer B) is the correct first step because it ensures a clean foundation for the sterile field and reduces contamination risk. Positioning the client (A) can be done before or after field preparation, while lubricating the catheter (C) and testing the balloon (D) are steps that occur after establishing the sterile field and donning sterile gloves. The foundational principle is that sterile fields must be established on clean, dry surfaces after proper hand hygiene. In practice, always prepare the environment and perform hand hygiene before opening sterile supplies to prevent contamination.

Question 13

A 66-year-old client with a history of coronary artery disease is in the operating room for a hip arthroplasty. The circulating nurse is monitoring sterile technique. Which action by the nurse is MOST important to maintain a sterile field during the procedure?

  1. Ensure sterile team members keep their hands at or below waist level to avoid fatigue
  2. Ask the anesthesia provider to adjust the sterile drape if it slips
  3. Allow the sterile back table to be used as a place to set the chart temporarily
  4. Remind non-scrubbed personnel to maintain at least 30 cm (12 in) distance from the sterile field (correct answer)
Explanation: This question tests the maintenance of sterile technique and sterile field in the operating room. Critical principles involve maintaining distance for non-scrubbed personnel to prevent accidental contamination. Reminding to keep 12 inches distance is most important to safeguard the field from reach or airflow issues. Hands below waist increase risk, back table is sterile, and anesthesia should not adjust drapes. The foundational principle of sterile technique requires spatial separation. Distance minimizes breaches. In practice, enforce buffer zones around sterile areas during procedures.

Question 14

A 48-year-old client with obesity is undergoing a surgical procedure. The circulating nurse notes the scrub nurse's sterile gown becomes damp at the abdomen after leaning against the sterile table edge. Which observation indicates a breach in sterile technique?

  1. Dampness is acceptable if sterile gloves remain dry
  2. The sterile gown remains sterile as long as it is above waist level
  3. Only visible blood on the gown indicates contamination
  4. A damp area is considered contaminated and the gown should be changed (correct answer)
Explanation: This question tests the maintenance of sterile technique and sterile field in the operating room. Critical principles include recognizing that moisture strikes through gowns, rendering them contaminated. A damp area indicates a breach as it allows microbial penetration through the gown. Waist level doesn't negate dampness, visible blood isn't the only sign, and glove dryness is irrelevant. The foundational principle of sterile technique is that barriers must remain dry and intact. Moisture compromises this. In practice, change damp gowns immediately to restore sterility.

Question 15

A 54-year-old client with diabetes mellitus is receiving a negative-pressure wound therapy dressing change for a large sacral ulcer. The RN opens the sterile supplies and prepares a sterile field on the overbed table. What should the nurse do FIRST to establish a sterile field?

  1. Don sterile gloves and arrange the sterile supplies on the overbed table before placing the sterile drape.
  2. Request an order for topical lidocaine, then apply it around the wound edges before beginning the dressing change.
  3. Remove the old dressing and measure the wound depth before placing the sterile supplies on the overbed table.
  4. Perform hand hygiene and clear the overbed table, then place the sterile drape to create the field. (correct answer)
Explanation: To establish a sterile field, the first action is to make the surface clean and safe: perform hand hygiene, clear the overbed table, and place a sterile drape. The sterile drape is the barrier that separates sterile supplies from the nonsterile table. Arranging supplies before the drape is placed is a sequence error because the undraped table is not sterile. Requesting and applying lidocaine may address pain, but it does not create a sterile field and is not the priority. Removing the old dressing and measuring the wound is part of dressing care, but it does not set up the sterile field. The field is created by preparing a clean work surface and placing the sterile drape, not by gloving, medicating, or measuring first.

Question 16

A 58-year-old client with peripheral arterial disease is receiving a sterile dressing change for a post-operative lower-leg incision. The RN opens a sterile dressing kit and sets it on the bedside table. Which action by the nurse maintains sterility?

  1. Open the first flap of the sterile package away from the body (correct answer)
  2. Lean over the sterile field to reach sterile gauze at the far edge
  3. Place sterile supplies within 1.25 cm (0.5 in) of the edge of the sterile drape
  4. Turn away from the sterile field to answer a question while keeping the field open
Explanation: This question tests the maintenance of sterile technique and sterile field for dressing changes. Critical principles involve opening packages away from the body to prevent contamination from reaching over. Opening the first flap away from the body maintains sterility by controlling wrapper movement and avoiding personal contact. Leaning over, placing near edges, or turning away risks contamination through reach or inattention. The foundational principle of sterile technique is to create barriers between sterile and non-sterile zones. Proper opening techniques ensure this separation. In practice, open packages methodically, starting with the farthest flap, to safeguard the field.

Question 17

A 62-year-old client with chronic kidney disease is having a central line inserted for vasopressor therapy. The RN is assisting with sterile supplies and notes the provider's sterile glove brushes against the client's bed sheet during positioning. Which action by the nurse maintains sterility?

  1. Document the event after the line is secured and dressing is applied
  2. Apply additional chlorhexidine to the insertion site and proceed
  3. Cover the bed sheet with a clean towel and continue without changing gloves
  4. Ask the provider to change the contaminated glove before continuing the procedure (correct answer)
Explanation: This question tests the maintenance of sterile technique and sterile field during central line insertion. Critical principles involve immediately addressing any contact between sterile items and non-sterile surfaces to prevent contamination. Asking the provider to change the contaminated glove maintains sterility by removing the breached item before proceeding. Applying more chlorhexidine or covering with a towel does not resolve glove contamination, and documenting later ignores the immediate risk. The foundational principle of sterile technique is that sterile items must only touch sterile surfaces. Contamination requires replacement, not continuation. In practice, advocate for sterility by halting the procedure and replacing contaminated items promptly.

Question 18

A 73-year-old client with heart failure has a peripherally inserted central catheter placed and now requires a sterile dressing change due to lifting edges. The RN prepares the sterile field and removes the old dressing with clean gloves. Which action by the nurse maintains sterility when transitioning to the sterile portion of the procedure?

  1. Apply sterile gloves after removing clean gloves and performing hand hygiene (correct answer)
  2. Keep the clean gloves on and apply the new sterile dressing carefully
  3. Use hand sanitizer over the clean gloves and then handle sterile supplies
  4. Ask assistive personnel to apply the sterile dressing while the RN holds the catheter in place
Explanation: This question tests the maintenance of sterile technique and sterile field for PICC dressing changes. Critical principles involve transitioning from clean to sterile phases with hand hygiene and new gloves. Applying sterile gloves after hygiene maintains sterility for handling supplies. Keeping clean gloves, using sanitizer over them, or delegating breaches protocol. The foundational principle of sterile technique separates clean removal from sterile application. Hygiene bridges this. In practice, remove old dressings with clean gloves, then hygienize before sterile gloving.

Question 19

A 52-year-old client with cirrhosis is in the intensive care unit and needs a central line insertion for multiple infusions. The RN is preparing to assist and notes the provider has donned a mask but has not placed a cap. What should the nurse do FIRST to maintain sterile technique during the procedure?

  1. Ask the provider to don a cap before the sterile field is established (correct answer)
  2. Apply sterile gloves to the provider's hands
  3. Begin skin antisepsis with chlorhexidine while the provider prepares supplies
  4. Proceed because a cap is optional if a mask is worn
Explanation: This question tests the maintenance of sterile technique and sterile field for central line insertion. Critical principles involve ensuring all PPE, including caps, is worn to cover hair and prevent contamination. Asking the provider to don a cap first maintains sterility by completing barrier precautions before field setup. Gloving or starting antisepsis without it risks hair fallout, and proceeding without is incorrect. The foundational principle of sterile technique requires full barriers to minimize microbial shedding. Caps are essential, not optional. In practice, verify all PPE is in place before opening sterile kits.

Question 20

A 79-year-old client with benign prostatic hyperplasia and acute urinary retention requires an indwelling urinary catheter insertion. During setup, the RN opens the sterile catheter kit on the bedside table and notices the outer wrapper touches the floor. Which action by the nurse maintains sterility?

  1. Continue using the kit because only the outer wrapper touched the floor
  2. Discard the kit and obtain a new sterile catheter kit before proceeding (correct answer)
  3. Wipe the wrapper with an alcohol pad and proceed with the same kit
  4. Ask the assistive personnel to open a new kit while the RN prepares the client
Explanation: This question tests the maintenance of sterile technique and sterile field during urinary catheter insertion. Critical principles include discarding any sterile item that contacts a non-sterile surface like the floor to prevent contamination. Discarding the kit and obtaining a new one maintains sterility as the outer wrapper's contact with the floor compromises the entire package. Continuing use or wiping ignores contamination risks, and delegating opening breaches protocol without addressing the issue. The foundational principle of sterile technique is that once contaminated, an item cannot be re-sterilized in a clinical setting. Contamination is assumed if packaging integrity is questioned. In practice, always err on the side of caution by replacing potentially contaminated supplies to ensure patient safety.
