Nursing MediumWHO 5 Moments: when to clean your hands
Hand hygiene reduces transfer of microorganisms during care. The five moments describe when to clean hands; they are not five rubbing steps.
| Moment | Indication | Example |
|---|---|---|
| 1 | Before touching a patient | Before checking a pulse or helping a patient move. |
| 2 | Before a clean/aseptic procedure | Immediately before handling a wound or accessing an IV line. |
| 3 | After body fluid exposure risk | After handling a used dressing or removing gloves after exposure risk. |
| 4 | After touching a patient | After examining the patient, before moving away. |
| 5 | After touching patient surroundings | After touching a bedrail or bedside surface, even without touching the patient. |
A change from a contaminated task to a clean task can require hand hygiene even for the same patient.
Hand rub vs soap and water
| Method | When? | WHO timing |
|---|---|---|
| Alcohol-based hand rub | Preferred for most routine clinical situations when hands are not visibly soiled. | 20–30 seconds for the whole hand-rub procedure; rub until dry. |
| Soap and water | When visibly dirty/soiled; after using the toilet; follow organism-specific and outbreak policy. | 40–60 seconds for the whole handwashing procedure. |
The WHO whole-procedure timing is not the same as a public handwashing message about scrubbing for at least 20 seconds. Read which guideline and part of the procedure an exam question asks about.
For suspected or confirmed C. difficile, norovirus or an outbreak, follow your facility’s organism-specific policy. Alcohol is not reliably sporicidal; do not assume one simple rule covers every clinical situation.
Technique: cover every surface
- For washing, wet hands and apply enough soap. For hand rub, apply the recommended amount to dry hands.
- Rub palms together and each palm over the back of the opposite hand, fingers interlaced.
- Clean between fingers and the backs of fingers against the opposite palm.
- Rub each thumb rotationally and clean fingertips against the opposite palm.
- For washing, rinse and dry thoroughly with a single-use towel; use the towel to turn off a hand-operated tap.
- For hand rub, continue rubbing until dry. Do not rinse it off or wipe it away.
Use enough product to cover all hand surfaces, including thumbs and fingertips. This is a revision summary; learn the full demonstrated technique and local policy during training.
Gloves do not replace hand hygiene
- Perform hand hygiene before putting on gloves when indicated and after removing them.
- Change gloves between patients, and between contaminated and clean tasks as required.
- Do not wash or reuse disposable examination gloves.
- Let hands dry before putting gloves on. Keep nails short; follow policy on artificial nails and jewellery.
10 original MCQs with rationales
Choose an answer before opening the explanation. These are original revision questions, not claimed PGIMER/NORCET previous-year questions.
Q1. A nurse is about to check a patient’s pulse. Which WHO moment applies?
- After touching surroundings
- Before touching a patient
- After body fluid exposure risk
- Only after removing gloves
Show answer & rationale
Answer: B. Before touching a patient
Clean hands before direct patient contact to reduce transfer of microorganisms to the patient.
Q2. After touching a bedrail, a nurse leaves without having touched the patient. Which moment applies?
- Before an aseptic task
- No hand hygiene is needed
- After touching patient surroundings
- Only before eating
Show answer & rationale
Answer: C. After touching patient surroundings
Moment 5 applies after contact with objects in the patient zone, even without direct patient contact.
Q3. Immediately before accessing an IV line, which moment is most relevant?
- Before a clean/aseptic procedure
- After touching a patient
- After touching surroundings
- Only after the shift
Show answer & rationale
Answer: A. Before a clean/aseptic procedure
An aseptic task requires hand hygiene immediately beforehand, even if the patient was already touched.
Q4. What is the WHO duration of the entire alcohol hand-rub procedure?
- 5–10 seconds
- 40–60 seconds
- 2–3 minutes
- 20–30 seconds
Show answer & rationale
Answer: D. 20–30 seconds
WHO specifies 20–30 seconds for hand rubbing. Cover all surfaces and continue until dry.
Q5. What is the WHO duration of the entire soap-and-water handwashing procedure?
- 10–15 seconds
- 40–60 seconds
- 20–30 seconds
- Exactly 5 minutes
Show answer & rationale
Answer: B. 40–60 seconds
The WHO handwashing procedure takes 40–60 seconds in total, including rinsing and drying.
Q6. A nurse’s hands are visibly soiled with blood. Which method is appropriate?
- Alcohol rub alone in every case
- Wipe on a clean uniform
- Wash with soap and water
- Put on another pair of gloves only
Show answer & rationale
Answer: C. Wash with soap and water
Visible soiling requires soap and water. Gloves or a quick wipe do not remove the contamination adequately.
Q7. A nurse removes gloves after handling a used wound dressing. What should happen next?
- Perform hand hygiene
- Skip hand hygiene because gloves were used
- Reuse the gloves after drying
- Wait until the end of the round
Show answer & rationale
Answer: A. Perform hand hygiene
Hand hygiene is needed after glove removal. Body fluid exposure risk is Moment 3; gloves can be contaminated or have defects.
Q8. After perineal care, the nurse prepares for a clean task on the same patient. What is best?
- Keep the same gloves because it is one patient
- Clean only the glove fingertips
- Proceed if gloves look clean
- Remove gloves, perform hand hygiene and use new gloves if indicated
Show answer & rationale
Answer: D. Remove gloves, perform hand hygiene and use new gloves if indicated
Moving from contaminated to clean work requires preventing transfer of organisms, even on the same patient.
Q9. What should a nurse do after applying alcohol-based hand rub?
- Rinse immediately
- Rub all surfaces until dry
- Wipe off with a towel
- Put on gloves while hands remain wet
Show answer & rationale
Answer: B. Rub all surfaces until dry
Hand rub should remain on the hands while rubbing until dry. Do not rinse or wipe it off.
Q10. Which statement about the WHO 5 Moments is correct?
- They are five surgical scrub strokes
- They apply only when gloves are not worn
- They describe indications for hand hygiene
- They replace all local infection-control policies
Show answer & rationale
Answer: C. They describe indications for hand hygiene
The five moments describe when hand hygiene is needed. Technique describes how; local policy and clinical circumstances still apply.
