A nurse is about to enter the room of a client with Clostridioides difficile infection during a facility C. difficile outbreak. The nurse's hands are not visibly soiled. Which hand hygiene plan best follows CDC guidance?
1Use alcohol-based hand rub before contact and omit hand hygiene after glove removal unless the hands look soiled.
2Use alcohol-based hand rub before contact; after care and glove removal, wash with soap and water as an outbreak precaution.✓ Correct answer
3Wash with soap and water before contact, then use only alcohol-based hand rub after glove removal despite the outbreak.
4Use alcohol-based hand rub before and after care because wearing gloves removes the need for outbreak-specific handwashing.
Explanation
During routine care, CDC prefers alcohol-based hand rub when hands are not visibly soiled, including care of clients with C. difficile. During a C. difficile outbreak, CDC encourages soap-and-water handwashing after care and glove removal as an additional precaution because washing mechanically removes spores better than alcohol. Gloves and a gown remain essential. Therefore option 2 is the most accurate plan. Options 1 and 4 omit post-care handwashing during an outbreak, and option 3 substitutes alcohol for the recommended post-care wash.
Clinical judgment Separate routine guidance from outbreak guidance. When hands are not visibly soiled, alcohol-based hand rub remains CDC's preferred routine method, even for C. difficile care. During a facility outbreak, add soap-and-water handwashing after care and glove removal because mechanical washing removes spores better than alcohol.
Safety bundle Use gown and gloves on entry, remove PPE without contaminating the hands, then perform the outbreak-specific hand hygiene step. Soap and water is also required whenever hands are visibly soiled.

Clinical scenario
Clinical Practice Guide CDC, SHEA, and IDSA classify C. difficile, Bacillus anthracis, and certain Norovirus exposures as situations where soap and running water are preferred over alcohol-based hand rub. For all other routine contacts in the absence of visible soiling, ABHR remains WHO-preferred (5 Moments of Hand Hygiene).
Caution NCLEX tests this exception heavily. If the prompt mentions C. difficile, Bacillus anthracis, Norovirus, or "visibly soiled", default to soap and water. Conversely, do NOT pick soap-and-water as default for routine contacts where alcohol is faster and gentler on skin.
Key concepts
Clostridioides difficile (C. difficile) — A spore-forming, anaerobic, gram-positive bacillus that causes pseudomembranous colitis. Spores are environmentally hardy and resistant to alcohol-based hand sanitizers, dictating soap-and-water hand hygiene during patient encounters.
Spore-forming organism — Bacteria capable of producing endospores — dormant, highly resistant structures that survive heat, drying, and chemical disinfectants including alcohol. Mechanical removal by soap-and-water friction is the recommended hand-hygiene method when caring for clients infected with these organisms.
Alcohol-based hand rub (ABHR) — WHO-preferred hand hygiene product for routine clinical contacts. Effective against vegetative bacteria, most viruses, and fungi, but NOT against bacterial spores. Should be used on visibly clean hands; replaced by soap-and-water when hands are visibly soiled or when caring for spore-forming organism infections.
