Hyperkalemia? Stabilize the heart first.
Calcium gluconate before insulin/D50 or albuterol — it protects the myocardium and buys you time; it doesn’t lower the K⁺.
SBAR in one breath.
Lead with the recommendation. “I need you to come see this patient” lands harder than a 90-second backstory.
Never run calcium & ceftriaxone together.
They precipitate in the line — risky in neonates especially. Flush well or use a second lumen. A 10-second check beats a code.
