Infection prevention technique
NCLEX infection-control technique: standard precautions, sterile field rules, PPE removal order, and the first steps after a needlestick.
Infection-prevention technique questions reward the nurse who keeps a sterile field honest, takes dirty PPE off in a safe order, and washes a needlestick before doing anything else.
Standard precautions are for everyone
Hand hygiene, gloves for blood and body fluids, sharps safety, and cough etiquette are baseline for all clients. Known diagnosis only adds transmission-based layers; it never subtracts the baseline.
- Clean (medical) asepsis: reduce organisms for most routine care.
- Sterile (surgical) asepsis: required for sterile procedures and many sterile dressing changes.
Sterile field rules that fail people on purpose
| Action | Result |
|---|---|
| Hands or sterile item drop below waist / out of sight | Contaminated |
| Turn back on the field | Contaminated |
| Moisture soaks through a sterile barrier | Contaminated |
| Reach across or drop a nonsterile item onto the field | Contaminated |
| Outer 1-inch border of many sterile packages | Considered nonsterile |
If contamination happens, stop and rebuild the field. Continuing “because you are almost done” is how surgical sites get infected on the exam and in real life.
PPE: put on for the risk, take off without self-contamination
Donning follows the exposure risk (contact, droplet, airborne, or combinations). Doffing is where most self-contamination happens. A common safe pattern for mixed airborne-and-contact gear is to remove gloves and gown carefully, exit, then remove the N95 last after leaving the room. Always follow the skill checklist your facility uses for testing.
Safety
Do not remove an N95 with soiled gloves as your first move inside an airborne room. Peel contaminated outer gear in order, perform hand hygiene between critical steps as taught, and keep the respirator on until you are out of the airborne space.
Needlestick exposure order
- Wash the site with soap and water immediately.
- Report the injury to the charge/occupational health pathway without delay.
- Seek evaluation for post-exposure prophylaxis and baseline labs as directed.
- Complete the occurrence report. Charting waits behind first aid and reporting.
Priority map
| Picture | First move |
|---|---|
| Any client care | Standard precautions |
| Hand dips below waist during sterile change | Contaminated; restart field |
| Leaving airborne + contact room | Doff outer gear safely; N95 after exit |
| Hollow-bore needlestick | Soap-and-water wash, then report/protocol |
Must know
- 1Standard precautions (hand hygiene, gloves for body fluids, safe sharps) apply to every client, not only those with a known infection.
- 2Medical (clean) asepsis reduces microbes. Surgical (sterile) asepsis aims for a sterile field for invasive procedures and sterile dressing changes when required.
- 3Sterile field contamination classics: turning your back, hands below waist, wet barrier soak-through, reaching across, nonsterile item touching sterile, talking over the field with droplets.
- 4PPE removal generally moves from most contaminated outer items to the respirator last when airborne protection was used; remove the N95 after leaving the room. Exact sequences follow current facility/CDC skill checklists.
- 5Inside a droplet room still wearing full PPE, the mask/face items come off in the correct doffing sequence; do not yank the respirator first while gloved and gowned if that breaks the sequence.
- 6Needlestick: wash the site with soap and water first, then report and follow occupational health exposure protocol (do not squeeze as the primary “treatment,” and do not delay washing to finish charting).
Memory hooks
Waist is the waterline
Sterile gloved hands and sterile items stay above the waist and in sight. Below the waist is contaminated.
Wash the stick first
After a needlestick, soap-and-water wash is the first action. Reporting and labs follow immediately after.
N95 leaves last
When airborne PPE was used, the respirator is removed after other contaminated gear and typically after exiting the room.
How it's tested
Stems highlight a hand dipping below the waist, ask for the next PPE item to remove, or put a needlestick in front of you. Distractors remove the N95 first while still gloved, treat standard precautions as optional for “low-risk” clients, or run to employee health before washing the site.
