Which is the most effective nursing action for preventing and controlling the spread of infection?

Infection prevention and control are essential components of nursing practice that safeguard both clients and healthcare providers. In healthcare settings, infections can be transmitted through direct contact, droplets, airborne particles, or contaminated surfaces.

Rationale for correct answer:

A. Thorough hand hygiene: Hand hygiene removes or destroys transient microorganisms. It interrupts the chain of infection by removing transient microorganisms from the hands before they can be spread to others or enter the body through mucous membranes or broken skin.

Rationale for incorrect answers:

B. Wearing gloves and masks when providing direct client care: Gloves and masks provide a barrier to infectious agents. However, they are not substitutes for hand hygiene and may be misused or improperly removed, potentially increasing the risk of contamination.

C. Implementing appropriate isolation precautions: Isolation precautions (e.g., contact, droplet, airborne) help limit the transmission of specific pathogens. They are essential for infection control when a known pathogen exists.

D. Administering broad-spectrum prophylactic antibiotics: Antibiotics may be used in select cases (e.g., pre-op or immunocompromised clients), but overuse contributes to antimicrobial resistance and disrupts normal flora.

Take home points:

• Hand hygiene is the most effective and universally applicable infection control measure in nursing practice.
• It should be performed before and after client contact, after removing gloves, and after contact with bodily fluids or contaminated surfaces.

Iatrogenic infections, also known as healthcare-associated infections (HAIs), are infections acquired during the course of receiving healthcare treatment. These infections can result from invasive procedures, improper hand hygiene, or contamination from the healthcare environment.

Rationale for correct answer:

A. Teaching correct handwashing to assigned patients: Hand hygiene is the most effective method to prevent the spread of infection. Educating patients on proper handwashing technique helps reduce transmission of pathogens.

B. Using correct procedures in starting and caring for an intravenous infusion: Proper aseptic technique when inserting and maintaining IV lines reduces the risk of bloodstream infections, a common type of HAI.

C. Providing perineal care to a patient with an indwelling urinary catheter: Perineal care prevents bacterial colonization around the catheter site and reduces the risk of catheter-associated urinary tract infections (CAUTIs), a common iatrogenic infection.

Rationale for incorrect answer:

D. Isolating a patient on antibiotics who has been having loose stool for 24 hours: While loose stool could suggest a Clostridioides difficile (C. diff) infection, isolation might not be warranted until there's confirmation-either through a positive lab result or continued symptoms with clinical suspicion. Premature isolation without evidence may not align with resource allocation or institutional policy.

E. Decreasing a patient’s environmental stimuli to decrease nausea: While comfort measures are important, reducing environmental stimuli for nausea does not contribute to the prevention of infections and is unrelated to infection control practices.

Take home points:

Preventing iatrogenic infections requires vigilance in patient care practices, including:

• proper catheter care
• IV-line maintenance
• patient education on hand hygiene among others
