C. difficile, a Shared Room, and a Family Member in the Hall
The lab report on the chart says Mrs. Nguyen, 69, has a positive C. difficile stool test. She has had seven watery stools since midnight, and her last stool was 20 minutes ago. The nurse has not yet put up a precaution sign. Mrs. Nguyen shares a room with Mrs. Patel, 74, who has a healing surgical incision on her right hip and an indwelling urinary catheter. Your assignment this morning is both residents, plus vital signs on two others. The blood pressure cuff, thermometer, and gait belt in the room are shared. Mrs. Nguyen asks to go to the dining room for breakfast, and Mrs. Patel's son stops you in the hallway to ask why the nurses are wearing yellow gowns.
1. You notice the precaution cart outside the room but no sign on the door. What do you do before entering either room, and what do you need from the nurse?

Before either room
- Stop and get the nurse. A positive C. difficile result is a transmitted infection and the precautions are not optional or mine to improvise. The nurse needs to place the sign, write the order, and tell me what equipment is dedicated to that room.
- Gather what I need before I go in: gown, gloves, a dedicated thermometer, a dedicated blood pressure cuff, and a gait belt that stays in her room. Nothing shared goes in.
- Do not enter Mrs. Patel's side first "just to get started." Once I have been in the C. difficile room, I am a vector for the next resident unless I doff and wash properly.
Why the missing sign is the real emergency here
Mrs. Patel has an open incision and a urinary catheter - two direct routes for this organism. Every hour without a sign, any staff member, visitor, or shared blood pressure cuff can carry spores from one bed to the other. The sign is not paperwork; it is the only thing that makes everyone who enters the room behave differently.
What I ask the nurse for: the precaution order and sign, dedicated equipment or a plan for cleaning, direction on whether Mrs. Nguyen may leave the room, and whether housekeeping needs a sporicidal clean of shared items already used.
2. Describe your PPE, your hand hygiene agent, the order in which you care for the two residents, and what happens to the shared equipment - with the reason behind each choice.

PPE
- Gown and gloves on entry, every entry, even for a two-minute task like handing her water. Contact precautions are for the room, not for the task.
- Remove the gown and gloves inside the room before touching the door handle, then perform hand hygiene.
Hand hygiene - soap and water, not alcohol gel
- C. difficile forms spores. Alcohol-based rub does not kill spores; it just moves them around. Soap and water with friction, at least 15–20 seconds, after glove removal and after any contact with the room or the resident. This is the single most important step and the one most often done wrong.
Order of care
- Everyone else first, Mrs. Patel next, Mrs. Nguyen last. Sequence is a control measure: I do not want to arrive at a resident with a fresh incision and a catheter carrying spores on my gloves or uniform.
- Mrs. Patel's catheter care gets its own gloves, and the drainage bag stays off the floor and below bladder level.
Equipment
- The shared cuff, thermometer, and gait belt leave the room only for a sporicidal clean, or better, stay in the room and a second set is issued to the roommate. Per facility policy, clean with a disinfectant labeled for C. difficile spores - bleach-based products are the usual choice, and alcohol wipes are not.
- Never drape a used gait belt over the roommate's chair. Never carry the cuff out under an arm.
Why all of this: C. difficile survives on surfaces for a long time, is spread by hands and equipment, and causes severe colitis in frail elderly residents. My hands are the delivery system, so my hand hygiene is the treatment.
3. How do you answer Mrs. Patel's son, and how do you handle Mrs. Nguyen's request to go to the dining room?
Read the worked answer
Mrs. Patel's son - in the hallway
- Move him away from the doorway first. The conversation should not be audible in the room.
- Answer the general question without confirming or denying anyone's diagnosis: "Gowns are used when a resident has an infection that can spread easily. The precautions protect everyone on the hall, including your mother. Her care hasn't changed."
- Do not name Mrs. Nguyen, do not describe her symptoms, and do not say "the lady in the other bed has C. diff." Even confirming which bed is affected is a privacy breach.
- Redirect specifics to the nurse: "The nurse can tell you more about your mother's precautions and what to watch for with her incision."
- Offer something useful: "The most helpful thing you can do is wash your hands when you leave her bedside."
Mrs. Nguyen and the dining room
- I do not simply say yes. Contact precautions usually mean meals in the room; that is a nursing decision, not mine.
- What I say: "You tested positive for a germ that causes diarrhea, and until it clears we keep you in your room for meals so it doesn't spread to other residents. I know that's not what you want to hear."
- Tell her why in plain language - people cooperate with precautions when they understand them, and stay angry when they don't. Also give her what she can still control: the chair, walking within the room, the phone, choosing her meal.
- Escalate both things to the nurse: the request to leave the room, and the fact that a resident on precautions was not told her own result. And report the son's question, because the nurse may want to do the education himself.
