A nurse is caring for a client who was admitted to the hospital and is scheduled for surgery in the morning due to a partial intestinal obstruction secondary to an intestinal mass.
For which clinical indicator most associated with an intestinal obstruction should the nurse assess the client?

Choice A rationale

Perineal hygiene is a critical component of infection control because the accumulation of fecal matter or secretions near the urethral meatus facilitates the migration of pathogenic bacteria up the catheter lumen. Proper cleansing, especially after bowel movements, reduces the microbial load and prevents the colonization of organisms like Escherichia coli. Maintaining a clean environment around the insertion site is a standard evidence based practice for reducing the incidence of catheter associated urinary tract infections in hospitalized patients.

Choice B rationale

Adequate hydration is vital because it promotes a steady flow of urine, which mechanically flushes the bladder and the urinary catheter. This continuous flushing action helps prevent the stasis of urine, which can otherwise serve as a medium for bacterial proliferation. Unless the patient has a medical contraindication such as congestive heart failure or renal failure, increasing fluid intake remains a primary non pharmacological intervention to maintain urinary tract health and prevent biofilm formation on the device.

Choice C rationale

Maintaining the drainage bag at or above the level of the bladder is incorrect and dangerous because it allows for the reflux of stagnant urine from the bag or tubing back into the bladder. Gravity should always be utilized to ensure one way flow away from the patient. Backflow carries contaminated urine and accumulated bacteria directly into the sterile bladder environment, significantly increasing the risk of infection. The bag should always be kept below the level of the bladder.

Choice D rationale

The urinary tract is naturally sterile, and the introduction of a foreign body like a catheter requires a strict aseptic technique to prevent the introduction of exogenous pathogens. Breaches in sterility during insertion are a leading cause of immediate post procedure infections. Using sterile gloves, drapes, and antiseptic solutions ensures that the initial environment remains uncontaminated, which is essential for preventing the early onset of healthcare associated infections in vulnerable or immunocompromised patients.

Choice E rationale

The application of powders to the perineal area is contraindicated in catheter care because powder can cake, trap moisture, and provide a substrate for bacterial or fungal growth. Additionally, particles from the powder can irritate the urethral meatus or become a source of crusting that makes hygiene more difficult. It does not provide a protective barrier and may lead to skin breakdown or inflammatory responses, which ultimately compromises the integrity of the primary defense against ascending infections.

Choice A rationale

Removing a soiled dressing before washing hands and preparing the environment is a violation of infection control principles. The nurse's hands could be contaminated from other tasks, and touching a wound site without prior hygiene increases the risk of healthcare-associated infections. Furthermore, flushing the wound before having a clean field ready can lead to contamination of the surrounding area. The sequence must begin with hand hygiene and proper preparation of the sterile field to ensure safety.

Choice B rationale

Pouring the solution before washing hands or removing the old dressing is disorganized and risks contaminating the sterile solution. If the nurse pours the solution first, it sits exposed to the air while the contaminated dressing is handled, increasing the risk of airborne pathogens settling in the liquid. Hand hygiene must always be the very first step in any sterile or clean procedure to minimize the transfer of microorganisms from the nurse to the client or equipment.

Choice C rationale

The correct sequence begins with washing hands to reduce the microbial load on the nurse. Next, the nurse prepares the sterile field to ensure all necessary supplies are ready and uncontaminated. Applying clean gloves to remove the old, soiled dressing protects the nurse from pathogens in the wound drainage. After removal, the nurse discards the contaminated gloves and performs hand hygiene again before donning sterile gloves for the irrigation. This flow maintains the highest standard of surgical asepsis.

Choice D rationale

Preparing the sterile field and putting on sterile gloves before removing the soiled dressing is incorrect because the sterile gloves would become contaminated the moment they touch the old dressing. Removing a soiled dressing is a "clean" task, not a "sterile" one. Once the old dressing is gone and the area is cleaned, the nurse should then transition to sterile gloves for the actual irrigation and application of the new sterile dressing to prevent cross-contamination.
