Safety and Infection Prevention and Control carries 10-16% of the NCLEX-RN, with a planning midpoint of 13% and roughly 9 to 18 scored items by our arithmetic. It tests transmission-based precautions, PPE, restraints, falls, medication safety, fire and disaster response. This is a pattern-matching category: the rules are fixed, and most errors come from mixing similar lists.
What this category covers
The category was renamed in the 2026 test plan from "Safety and Infection Control" to "Safety and Infection Prevention and Control", but the percentage range did not change. Its 18 subtopics fall into four groups.
- Infection prevention: standard precautions and hand hygiene; airborne, droplet and contact precautions; PPE donning and doffing; surgical asepsis; prevention of central line infection, catheter-associated urinary tract infection, ventilator-associated pneumonia and surgical site infection.
- Injury prevention: fall risk screening, restraints and seclusion, safe patient handling and ergonomics, home safety teaching, security plans for infant abduction, workplace violence and elopement.
- Medication and equipment safety: error prevention and incident reporting, oxygen, suction, infusion pumps and electrical safety.
- Emergencies: fire safety, disaster triage and mass-casualty plans, hazardous materials, chemotherapy and radiation safety, bioterrorism and emerging infections.
Guideline points to know
| Topic | Rule |
|---|---|
| Airborne | Private negative-pressure airborne infection isolation room and an N95 or higher respirator for tuberculosis, measles, varicella and disseminated herpes zoster. |
| Droplet | Private room preferred, surgical mask, for influenza, pertussis, mumps, rubella, meningococcal disease (until 24 hours of effective therapy), Mycoplasma and adenovirus. |
| Contact | Gown and gloves for MRSA, VRE, C. difficile, scabies, norovirus and RSV. Soap and water for C. difficile and norovirus because alcohol rub does not kill spores. |
| PPE sequence | On: gown, mask or respirator, goggles or face shield, gloves. Off: gloves, goggles or face shield, gown, mask or respirator last, then hand hygiene. |
| Hand hygiene | Alcohol-based rub if not visibly soiled; soap and water for at least 20 seconds if soiled. |
| Restraints (CMS) | Only for violent or self-destructive behavior. No PRN or standing orders. Order limits: 4 hours adults, 2 hours ages 9 to 17, 1 hour under 9. Face-to-face evaluation within 1 hour. Release at the earliest possible time. |
| IV tubing and lines | CDC: replace administration sets no more often than every 96 hours, at least every 7 days for continuous infusions; chlorhexidine skin antisepsis; remove unneeded central lines promptly. |
| Urinary catheters | Insert only for appropriate indications and remove as soon as possible. |
| Medication safety | Five rights plus documentation; two identifiers; Joint Commission Do-Not-Use list (U, IU, Q.D., Q.O.D., trailing zero, missing leading zero, MS, MSO4, MgSO4). |
| Fire | RACE: rescue, alarm, contain, extinguish or evacuate. PASS: pull, aim, squeeze, sweep. Close oxygen sources and clamp supply when evacuating clients on oxygen. |
| Radiation | Time, distance and shielding. |
Three typical traps
- Swapping airborne and droplet. Tuberculosis, measles and varicella need the respirator and negative-pressure room. Influenza and pertussis need a surgical mask. When a stem lists a disease, name its precaution before you read the options.
- Using alcohol rub for spores. For C. difficile and norovirus, soap and water is the answer; alcohol rub is the tempting wrong option.
- Restraint as first response. The correct sequence uses the least restrictive option first (reorient, address the cause, offer toileting, sitter, environmental change), and restraints need a time-limited order and a face-to-face evaluation. An option that applies restraints "to prevent a fall" without alternatives is wrong.

How to revise it
- Make one precautions table. Three columns (airborne, droplet, contact), diseases in rows, with room type and PPE. Recite it from memory daily for two weeks.
- Rehearse PPE order physically. Say the donning and doffing sequence aloud while miming it. The order, especially that the mask or respirator comes off last, is tested in several formats, including drag-and-drop.
- Learn restraint rules as numbers. 4, 2 and 1 hours; 1-hour evaluation; no PRN.
- Sort errors by cause. For medication safety items, ask whether the problem was identification, dose, route, time or documentation.
- Do disaster triage by category. Know the principle: assess and tag by severity, save the most lives. Triage systems such as START (adults) and JumpSTART (children) are named in the test plan subtopics.
- Link to case studies. Infection-control stems often become Next Generation items where you choose the precautions and the actions. Practice with the NGN guide.
Pairing with other categories
Safety overlaps with Management of Care (incident reporting, staffing), Pharmacological and Parenteral Therapies (high-alert drugs, line care) and Reduction of Risk Potential. The high-yield topics guide holds the compact fact list. At the midpoint, 13 of every 100 study hours go here, and much of that can be short daily recall sessions rather than long blocks.
How the items are phrased
Safety items rarely ask for a definition. They give a client and a risk and ask for the action, the room or the order of steps. Four patterns cover most of them.
- Choose the precaution. The stem names a diagnosis or symptom cluster (for example, a rash with fever in a child, or a persistent cough with night sweats). Name the transmission route first, then pick the room and the PPE. For a suspected airborne disease, precautions start before the diagnosis is confirmed.
- Order the steps. Drag-and-drop items ask for the PPE sequence, a sterile field set-up or the steps of a fire response. Say the order aloud before you drag.
- Find the unsafe action. "Which action by the nurse requires intervention?" items reward the habit of scanning for broken technique: contaminating a sterile field, leaving a bed high, skipping a second identifier.
- Prevent the fall or the elopement. After you screen for fall risk (the Morse scale is one named tool), the interventions are low bed, brakes on, call light in reach, non-slip footwear, scheduled toileting and review of medications that sedate. Restraints are last, not first.
Disaster questions test triage logic: the client with a salvageable, life-threatening problem such as airway compromise or uncontrolled bleeding is seen before one who is walking and stable, and clients who cannot survive with available resources are managed last. Learn the principle, then the named systems in the blueprint (START for adults, JumpSTART for children).

Frequently asked questions
What percentage of the NCLEX-RN is safety and infection control?
The 2026 test plan range for Safety and Infection Prevention and Control is 10-16%, with a planning midpoint of 13%.
Which diseases need airborne precautions?
Tuberculosis, measles, varicella and disseminated herpes zoster need a negative-pressure airborne infection isolation room and an N95 or higher respirator.
When is soap and water required instead of alcohol rub?
When hands are visibly soiled, and for C. difficile and norovirus, because alcohol rub does not kill spores.
What are the time limits for restraint orders?
CMS limits are 4 hours for adults, 2 hours for ages 9 to 17 and 1 hour under 9, with a face-to-face evaluation within 1 hour. Orders cannot be PRN or standing.
