Nursing Mnemonics Organised by Body System
A mnemonic is a retrieval hook, not understanding: used well it gets a fact out of your head under pressure, used badly it replaces the clinical reasoning the NCLEX is actually testing. Learn the handful that encode something you genuinely cannot derive, such as VEAL CHOP for fetal heart tracings, ROME for blood gases, Cushing's triad, and the airborne precautions list, and skip the ones that just relabel knowledge you already have.

A mnemonic is a retrieval hook, not understanding. Used well it gets a fact out of your head under pressure; used badly it replaces the reasoning the NCLEX is actually testing. Everything below is the first kind.
Cardiac
| Mnemonic | Stands for | Used for |
|---|---|---|
| MONA | Morphine, Oxygen, Nitroglycerin, Aspirin | Acute coronary syndrome. Note the modern order gives aspirin early, not last |
| All People Enjoy Time Magazine | Aortic, Pulmonic, Erb's point, Tricuspid, Mitral | Cardiac auscultation sites, base to apex |
| Beck's triad | Hypotension, muffled heart sounds, JVD | Cardiac tamponade |
| Left = Lungs | Left-sided failure backs into the lungs; right into the Rest of the body | Heart failure findings |
Respiratory
| Mnemonic | Stands for | Used for |
|---|---|---|
| ROME | Respiratory Opposite, Metabolic Equal | Arterial blood gas interpretation |
| The four Ds | Drooling, Dysphagia, Dysphonia, Distress | Epiglottitis — and never look in the throat |
| My Chicken Hez TB | Measles, Chickenpox, Herpes zoster, TB | Airborne precautions |
Neuro
| Mnemonic | Stands for | Used for |
|---|---|---|
| FAST | Face drooping, Arm weakness, Speech difficulty, Time to call | Stroke recognition |
| PERRLA | Pupils Equal, Round, Reactive to Light, Accommodation | Pupil assessment |
| AVPU | Alert, Verbal, Pain, Unresponsive | Rapid level-of-consciousness check |
| Cushing's triad | Rising BP with widening pulse pressure, falling pulse, irregular respirations | Increased intracranial pressure — a late and ominous sign |
Maternity and newborn
| Mnemonic | Stands for | Used for |
|---|---|---|
| VEAL CHOP | Variable/Cord, Early/Head, Accelerations/Okay, Late/Placental | Fetal heart tracings |
| LION | Left side, IV fluids, Oxygen, Notify | Response to late decelerations |
| APGAR | Appearance, Pulse, Grimace, Activity, Respiration | Newborn scoring at 1 and 5 minutes |
| TORCH | Toxoplasmosis, Other, Rubella, Cytomegalovirus, Herpes | Congenital infections |
| Four Ts | Tone, Trauma, Tissue, Thrombin | Causes of postpartum haemorrhage — tone is the commonest |
Pharmacology
| Mnemonic | Stands for | Used for |
|---|---|---|
| Suffix families | -olol beta blocker, -pril ACE, -sartan ARB, -dipine CCB, -statin lipid, -prazole PPI, -parin anticoagulant | Identifying an unfamiliar drug's class |
| Six rights | Right drug, dose, route, time, client, documentation | Medication administration |
| SLUDGE | Salivation, Lacrimation, Urination, Defecation, GI upset, Emesis | Cholinergic excess / organophosphate poisoning |
| Can't see, can't pee, can't spit, can't poop | Blurred vision, retention, dry mouth, constipation | Anticholinergic side effects |
Safety, priorities and assessment
| Mnemonic | Stands for | Used for |
|---|---|---|
| ABC | Airway, Breathing, Circulation | Priority order — always run it first |
| RACE | Rescue, Alarm, Confine, Extinguish | Fire response, in that order |
| PASS | Pull, Aim, Squeeze, Sweep | Using an extinguisher |
| SBAR | Situation, Background, Assessment, Recommendation | Handoff and escalation |
| PQRST | Provocation, Quality, Region, Severity, Timing | Pain assessment |
| SPLATT | Symptoms, Previous falls, Location, Activity, Time, Trauma | Post-fall assessment |
Labs and electrolytes
| Hook | Meaning |
|---|---|
| Low potassium = quiet gut. High potassium = loud gut | Hypokalemia slows smooth muscle; hyperkalemia irritates it |
| Flat T with a U = low K. Peaked T = high K | Potassium ECG changes |
| Vomiting = alkalosis, diarrhea = acidosis | Stomach contents are acid; intestinal contents are alkaline |
| Chvostek and Trousseau | Both signs of low calcium |
Where mnemonics let you down
They give you a list, not a decision. MONA tells you the four things in acute coronary syndrome; it does not tell you to hold the nitroglycerin because the systolic is 84, and that is what the question will ask. Use the hook to retrieve the list, then think about this client.
They also go out of date. MONA is still taught but the order it implies is no longer the recommended sequence. Treat any mnemonic as a memory aid whose clinical logic you should still be able to explain — if you cannot, you have memorised the letters and not the nursing.
NCLEX tip: Learn the handful that encode something you genuinely cannot derive — VEAL CHOP, ROME, Cushing's triad, the airborne list. Skip the ones that just relabel knowledge you already have. Twenty mnemonics you can use beat fifty you half-remember.

Frequently asked questions
Common follow-up questions on Study Plans & Timelines.
What is ROME used for?
ROME stands for Respiratory Opposite, Metabolic Equal, and it is used for arterial blood gas interpretation. It is one of the mnemonics worth learning because it encodes a relationship you cannot easily derive under pressure.
What does VEAL CHOP help me remember?
VEAL CHOP is used for fetal heart tracings: Variable with Cord, Early with Head, Accelerations are Okay, and Late with Placental problems. It is a high-value mnemonic because it captures the cause behind each tracing pattern.
What is Cushing's triad?
Cushing's triad is rising blood pressure with a widening pulse pressure, a falling pulse, and irregular respirations. It signals increased intracranial pressure and is a late and ominous sign. It is worth memorizing because it packages several findings into one recognizable emergency.
How do I remember the airborne precautions diseases?
The mnemonic 'My Chicken Hez TB' covers Measles, Chickenpox, Herpes zoster, and TB, the conditions needing airborne precautions. It is one of the mnemonics that encodes a list you cannot otherwise derive, which is exactly the kind worth keeping.
Where do mnemonics let students down?
They give you a list, not a decision. MONA tells you the four things in acute coronary syndrome, but it does not tell you to hold the nitroglycerin because the systolic is 84: and that is what the question will ask. Mnemonics also go out of date; MONA is still taught but the order it implies is no longer the recommended sequence, so treat any mnemonic as a memory aid whose clinical logic you can still explain.
