NCLEX Isolation Precautions Made Simple: PPE, Diseases, and the Mnemonics That Stick (2026)

Infection control is a guaranteed NCLEX category, and isolation precautions are where students lose easy points. The good news is that this is pure memorization with a clear structure. Learn the three precaution types, the PPE for each, and the key diseases, and you will answer these questions in seconds.

The three transmission-based precautions

Every isolation question comes down to which of these three applies, plus standard precautions underneath all of them.

Airborne

Tiny particles that hang in the air. Requires a negative pressure room and an N95 respirator.

Memory trick: My Chicken Hez TB. Measles, Chickenpox (varicella), Herpes zoster (disseminated), and TB are your airborne diseases.

Droplet

Larger droplets from coughing or sneezing that travel a short distance. Requires a private room and a surgical mask.

Memory trick: SPIDERMAN. Sepsis, Scarlet fever, Streptococcal pharyngitis, Pertussis, Pneumonia, Parvovirus, Influenza, Diphtheria, Epiglottitis, Rubella, Mumps, Meningitis, Mycoplasma, and Adenovirus.

Contact

Spread by touch. Requires gloves and a gown.

Memory trick: MRS WEE. MRSA, RSV, Skin infections, Wound infections, Enteric infections like C. diff, and Eye infections (conjunctivitis). Remember that C. diff needs soap and water, not alcohol gel.

Donning and doffing PPE in the right order

The NCLEX loves order-of-steps questions here.

• Donning (putting on): gown, mask, goggles, gloves.
• Doffing (taking off): gloves, goggles, gown, mask. The gloves come off first because they are the most contaminated.

Tie it to clinical judgment

On the NGN, you will often get a client scenario and have to choose the precaution and the PPE together. Practice spotting the disease, naming the precaution, and selecting the PPE as one motion.

Where to drill this

Infection control is included as a full high-yield section in our 2026 NCLEX Ultimate Mastery Notes, with the mnemonics above plus the PPE order laid out for fast review. If you also want to sharpen your overall test approach, our piece on prioritization questions pairs well, since safety and infection control often drive who you see first.

Memorize the three types, lock in the mnemonics, and isolation precautions become some of the fastest points on your exam.
