C. difficile, a Shared Cuff, and the Next Resident Waiting
Mr. Chen has had four unformed, foul-smelling stools since midnight and is on contact precautions for a confirmed Clostridioides difficile infection. At 0745 you are assigned to clean him up and change his linens. His roommate's bed is about two meters away and the privacy curtain is pulled. You have a small bandaged cut on your right index finger. The alcohol-based hand rub is mounted just outside the door; the sink is down the hall. After Mr. Chen you are scheduled to take another resident to physical therapy for a 0800 appointment, and the shared blood pressure cuff you used on Mr. Chen is still in his room.
1. What personal protective equipment do you use and how do you clean your hands around this room? Explain the reasoning.
Read the worked answer
PPE: gloves and a gown for the clean-up and linen change, as the care plan and posted precautions direct. Don them before entering the room and remove them before leaving. The bandaged cut must be covered and dry before you start; if it cannot be covered, tell the nurse before providing care.
Hand hygiene: soap and water, not the alcohol rub. C. difficile spreads by spores, and alcohol does not reliably kill spores - friction and running water physically remove them. Wash after doffing gown and gloves, before leaving the room.
Reasoning: the posted alcohol rub is the convenient choice and the wrong one for this organism. The cut matters because a break in the skin is an entry point and a place organisms can hide from a hand rub.
2. Can you go straight from his room to take the next resident to physical therapy? What has to happen first?
Read the worked answer
Not straight from the room. Before you leave: remove gown and gloves inside the room, wash hands with soap and water, and leave the shared blood pressure cuff in Mr. Chen's room.
Reasoning: the cuff is a shared item that has been against his skin and is now a transport vehicle to the next resident. Use a dedicated cuff for him, or clean and disinfect the cuff per facility policy (a bleach-based product for spore-forming organisms) and let it dry before it goes to anyone else. Do not carry it out draped over your arm. If the cuffed equipment cannot be cleaned quickly, borrow another cuff for the 0800 appointment. Also do not take a shared item into a common area, and do not let the roommate use it.
3. What do you report to the nurse, and what is outside your role here?
Read the worked answer
Report: number and character of stools and times (four since midnight, unformed, foul-smelling), any blood or mucus, complaints of abdominal pain or cramping, the condition of the perianal skin, signs of dehydration (dry mouth, dark urine, dizziness), whether he is eating and drinking, and any new incontinence.
Outside your role: deciding when precautions end, starting or changing a diet, giving an anti-diarrheal, or telling the roommate's family why Mr. Chen is on precautions. Those are nurse or provider decisions and, for the roommate, a confidentiality matter.
Reasoning: the CNA is the eyes on this resident. Frequent unformed stools plus a spore-forming organism are exactly the situation where perianal skin breakdown and dehydration develop fast, and both are reportable observations rather than things you treat on your own.
