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?
Ask the client to hold still while the RN steps away briefly, leaving the sterile field unattended
Continue the dressing change and address the call light after the sterile dressing is applied
Ask assistive personnel to reposition the call light while the RN remains at the sterile field
Remove sterile gloves, adjust the call light, then don new sterile gloves and continue with the same sterile field
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.
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?
The assisting nurse places sterile ultrasound gel on the probe after applying a sterile probe cover
The assisting nurse maintains the sterile field at or above waist level
The assisting nurse reaches over the sterile field to plug in a nonsterile device
The assisting nurse wears a mask, cap, sterile gown, and sterile gloves
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.
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?
Increase the room temperature to reduce airborne contamination risk
Ask staff to minimize door openings and keep traffic in and out of the room to a minimum
Ask the scrub nurse to turn away from the sterile field when the door opens
Place a clean sheet over the sterile back table and continue allowing door openings
Explanation
This question tests the maintenance of sterile technique and sterile field in the operating room. Critical principles include minimizing air currents and traffic to reduce airborne contamination. Asking to minimize door openings is best to preserve the field's integrity from drafts and personnel. Covering with clean sheet, turning away, or increasing temperature doesn't address traffic. The foundational principle of sterile technique limits environmental disturbances. Traffic increases contamination risk. In practice, coordinate with team to restrict entries and maintain a controlled environment.
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?
Discard the catheter and obtain an unexpired sterile catheter before proceeding
Proceed and document the expiration date after the catheter is inserted
Soak the catheter in antiseptic solution to compensate for expiration
Use the catheter because the package is unopened and appears intact
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.
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?
Cover the tear with a piece of sterile gauze and continue
Ignore the tear because it is near the edge of the drape
Apply additional skin antiseptic to compensate for the tear
Replace the torn drape with a new sterile drape before proceeding
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.
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?
Sterile drapes are applied from the incision site outward
A sterile team member turns their back to the sterile field while adjusting their mask
The circulating nurse remains outside the sterile field while documenting
The scrub nurse keeps sterile hands above waist level and in view
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.
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?
Use clean gloves to cleanse the perineum and then proceed without changing gloves
Place the sterile catheter tip on the sterile drape while adjusting the light with the same gloved hand
Hold the catheter 2.5 cm (1 inch) from the tip to guide insertion while keeping it above the sterile field
Keep the dominant hand sterile while using the non-dominant hand to separate the labia and maintain that position
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.
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?
Lubricate the catheter tip and place it on the sterile drape
Position the client in dorsal recumbent position and drape for privacy
Inflate the catheter balloon with sterile water to test for leaks
Perform hand hygiene and verify that the bedside table surface is clean and dry
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.
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?
Remind non-scrubbed personnel to maintain at least 30 cm (12 in) distance from the sterile field
Ask the anesthesia provider to adjust the sterile drape if it slips
Ensure sterile team members keep their hands at or below waist level to avoid fatigue
Allow the sterile back table to be used as a place to set the chart temporarily
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.
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?
A damp area is considered contaminated and the gown should be changed
The sterile gown remains sterile as long as it is above waist level
Only visible blood on the gown indicates contamination
Dampness is acceptable if sterile gloves remain dry
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.
