Must Remember
- **Hand hygiene is the SINGLE MOST EFFECTIVE infection-control measure** — breaks the chain of infection at the transmission link. Use soap & water for C. difficile (spores); alcohol-based rub for routine.
- **Chain of Infection has 6 links:** agent → reservoir → portal of exit → transmission → portal of entry → susceptible host. Break ANY ONE to interrupt transmission.
- **Medical asepsis (clean) REDUCES number of microorganisms; surgical asepsis (sterile) ELIMINATES ALL microorganisms and spores** — only sterile touches sterile in sterile field.
- **1-inch (2.5 cm) OUTER BORDER of sterile field = CONTAMINATED; anything BELOW WAIST LEVEL = CONTAMINATED** — key rules for maintaining surgical asepsis.
- **MOISTURE WICKS MICROORGANISMS (strike-through)** — a wet sterile field is contaminated; do not reach across sterile field; if in doubt, it's contaminated.
- **Airborne precautions (MTV: Measles, TB, Varicella) require N95 respirator + negative-pressure room; droplet (influenza, pertussis) requires surgical mask only; contact (MRSA, C. difficile) requires gown & gloves.**
- **PPE donning:** gown → mask → goggles → gloves; **doffing:** gloves → goggles → gown → mask (remove mask LAST, outside room) — then perform hand hygiene.
- **Fall prevention:** bed in LOWEST position with BRAKES LOCKED; call light in reach; fall-risk identifier (color-coded band); adequate lighting; assist high-risk patients; attend to orthostatic hypotension (rise slowly).
- **Patient identification:** use **at least TWO identifiers** (name + birthdate/hospital number) — never room number alone. WHO Surgical Safety Checklist prevents wrong-site surgery.
- **CAUTI prevention:** insert only when indicated; aseptic technique; closed drainage system; **keep bag BELOW bladder level**; remove early. CLABSI: chlorhexidine prep, maximal barriers, daily review. VAP: head 30–45°, oral care, spontaneous breathing assessment. SSI: prophylactic antibiotics within 60 min, glucose control, sterile technique.
Last Minute Tips
- **Memorize the 1-inch border rule and waist-level rule for surgical asepsis** — these appear in almost every NLE exam question about sterile technique. Picture the field: center is sterile, 1-inch edges contaminated, everything below your waist is contaminated.
- **MTV = Measles, TB, Varicella for airborne precautions (N95 + negative-pressure room).** Droplet precautions use surgical mask only. Contact precautions use gown + gloves. You WILL see a question asking you to differentiate these.
- **Hand hygiene at 5 WHO Moments is HIGH-YIELD.** Practice reciting them: before touching patient, before aseptic procedure, after body-fluid exposure, after touching patient, after touching surroundings. If asked 'when should you perform hand hygiene?' the answer is often one of these five.
- **Fall prevention combines environmental safety (bed low, call light in reach, lighting, non-slip floors) + patient assessment (Morse Fall Scale) + interventions (assist ambulation, attend to orthostatic hypotension, fall-risk ID band).** Don't memorize just the assessment tool — you must know the FULL bundle.
- **Never recap needles and dispose immediately in sharps containers.** This is a safety principle tested on every NLE exam. Also remember: four side rails up = restraint (needs physician order); three side rails = OK.
