1. SLUDGE — Cholinergic Drug Effects

When a cholinergic drug (or cholinesterase inhibitor) amps up your parasympathetic nervous system, think SLUDGE:

\n\n
Why it works: SLUDGE maps directly to parasympathetic activation — \"rest and digest\" overdrive. If you see these symptoms on the NCLEX, think cholinergic excess or organophosphate poisoning. The antidote? Atropine.
\n

2. Drug Suffix Stems — Decode Any Drug Name

You don't need to memorize 300 individual drugs. Learn the suffixes and you can identify the class on sight:

\n\n
Pro tip: If the NCLEX gives you an unfamiliar drug name, check the ending first. You can often reason through the entire question from the drug class alone.
\n

3. Anticoagulant Monitoring — \"aPTT for the P, PT/INR for the Pill\"

Heparin is parenteral (IV/subQ) → monitor aPTT. Warfarin is the pill (oral) → monitor PT/INR. Match the P's and you'll never mix them up.

\n
High-alert: Anticoagulant monitoring is one of the most frequently tested pharmacology topics on the NCLEX. Know the therapeutic ranges and the antidotes — protamine for heparin, vitamin K for warfarin.
\n

Make Them Stick

A mnemonic only works if you pair it with understanding. Learn the shortcut, then immediately ask why — that connection is what holds up under NCLEX pressure. Practice applying these in NCLEX-style questions and you'll retrieve them automatically on exam day.
