Contact Precautions, explained for the bedside and the exam
Written and reviewed by Dana Whitfield, RN, MSN · 4 min read · Updated September 2026
Short answer
Contact precautions require a gown and gloves on entry to the room, plus dedicated or disposable equipment for that patient alone. For Clostridioides difficile specifically, wash hands with soap and water rather than alcohol-based sanitiser, because C. diff spores are not killed by alcohol.
Defining it precisely
Contact precautions apply to organisms spread by direct touch or by contact with contaminated surfaces and equipment. Anyone entering the room puts on a gown and gloves before touching the patient or their environment, and removes both before leaving. This isn't a mask-based category; respiratory protection isn't the point unless another indication exists alongside it.
Equipment gets dedicated to the patient wherever possible: a single-patient stethoscope, blood pressure cuff, and thermometer stay in the room rather than travelling the unit. When shared equipment must be used, it's disinfected before it leaves. Common triggers include MRSA, VRE, Clostridioides difficile, scabies, and draining wounds colonised with resistant organisms.
The exceptions that matter
C. difficile is the exception every exam writer loves. Standard alcohol-based hand sanitiser doesn't kill C. diff spores, so hand hygiene must be soap and water, with the mechanical friction of washing physically removing spores from the skin. Gel alone, even used correctly and frequently, leaves the spores intact.
This matters at the sink, not just at triage: a nurse who gels in and out of a C. diff room using perfect technique everywhere else is still practicing incorrectly for that specific organism. The gown-and-gloves requirement doesn't change, only the hand hygiene agent does. During a facility-wide C. diff outbreak, some units also restrict alcohol gel use at the bedside station entirely and post signage requiring the sink.
Using it to prioritise
On a shift with multiple assignments, contact precaution patients aren't automatically the sickest, but the sequencing of care still matters. Many units schedule contact-precaution rooms last in a medication pass or wound-care round, purely to limit the number of gown-and-glove changes and reduce the chance equipment carries organisms between rooms.
When prioritising which patient to see first in an emergent situation, isolation status doesn't override acuity. A stable MRSA-colonised patient waits behind an unstable patient without precautions. The exam expects you to don PPE quickly rather than delay care to a genuinely urgent contact-precaution patient, but it also expects you not to skip the gown for the sake of speed when the situation is not emergent.
Traps in exam wording
Watch for stems that mention hand sanitiser at a C. diff patient's door and ask what the nurse should do. The correct action is to redirect to soap and water, not to accept the gel dispenser as adequate. This is one of the few points in infection control where the more convenient, more universally-taught practice (alcohol gel) is the wrong answer for a specific organism.
Another trap: gloves alone without a gown. Contact precautions require both, even for tasks that seem glove-only, like adjusting an IV line, because the gown protects clothing from surface contamination that then travels to the next patient. A third: reusing a stethoscope after wiping it with an alcohol pad for a C. diff patient. Alcohol doesn't reliably kill spores on equipment either; a sporicidal disinfectant, per facility policy, is needed.
Examples from practice
A patient with a MRSA-colonised wound needs a dressing change. The nurse gowns and gloves before entering, uses supplies from a dedicated cart kept in the room, and removes PPE before exiting, disposing of gown and gloves inside the room per facility protocol.
A patient develops watery diarrhea and testing confirms C. difficile. The bedside alcohol dispenser is not the answer for hand hygiene before or after care; the nurse washes at the sink with soap and water, in the room if available, for the full recommended duration, before doffing gloves and again after.
Summary
Contact precautions mean gown and gloves on entry and dedicated equipment, protecting against organisms spread by touch rather than by air or droplet. C. difficile is the standout exception that shifts hand hygiene from alcohol gel to soap and water, because spores survive the gel.
Keep the gown-and-glove pairing intact even for brief tasks, and never let convenience substitute the wrong hand hygiene agent for C. diff. Sequencing contact-precaution care doesn't override acuity, but it does shape workflow when everything else is equal.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our safe and effective care practice questions are the closest set to what this page covers.
One question from the safe and effective care set
A nurse on a medical unit receives report on four clients. Which client should the nurse assess first?
Rationale
Prioritization items are airway, breathing, circulation, in that order — the ranking survives every rewording. Audible gurgling around a fresh tracheostomy is a partially obstructed airway and it is the only option that can kill the client in the next few minutes. Fever, post-op pain, and a glucose of 232 are all real problems that need the nurse, just not first.
Answer: C
Common questions
Why doesn't alcohol hand gel work for C. difficile?
C. difficile forms spores that are resistant to alcohol-based sanitisers. Soap and water hand washing physically removes spores through friction and rinsing, which alcohol alone cannot do.
Do I need a mask for contact precautions?
Not by default. Contact precautions are gown and gloves; a mask is only added if another indication, such as droplet precautions or splash risk, applies at the same time.
Can I wear the same gown between two contact-precaution patients?
No. Gowns and gloves are single-patient use and are removed and discarded before leaving that patient's room, then replaced with a fresh gown and gloves for the next patient.
Is a stethoscope wiped with an alcohol pad safe to reuse on a C. diff patient?
Alcohol alone isn't reliably sporicidal, so a dedicated stethoscope for that patient is preferred. If shared equipment must be used, it needs a disinfectant proven effective against C. difficile spores, per facility policy.
What organisms typically require contact precautions?
MRSA, VRE, Clostridioides difficile, scabies, and wounds colonised with multidrug-resistant organisms are the common triggers. Facility policy determines exact criteria and duration.
