Critical Safety Rules:
- NEVER GIVE IV PUSH OR BOLUS: Rapid IV push causes instant cardiac arrest and is lethal.
- Maximum Peripheral Infusion Rate: $10$ mEq/hour (can give up to $20$ mEq/hr ONLY via Central Venous Catheter with continuous cardiac monitoring).
- Dilution: Must always be diluted in IV fluids (never add to a hanging IV bag; mix thoroughly).
- Renal Function Check: "No pee, no K" — always confirm urine output $> 30$ mL/hr before starting replacement.
