Likelihood of appendicitis based on symptoms, signs, and lab data.
Clears head injury without imaging.
Criteria for which patients are unlikely to require imaging after head trauma.
Provides the PECARN algorithm for evaluating pediatric head injury.
Calculates PO/IV NAC dosing for acetaminophen overdose (and nomogram to determine toxic 4 hour level).

Estimates viability of an extremity after trauma, to determine need for salvage vs empiric amputation.
Stratifies Upper GI bleeding patients who are "low-risk" and candidates for outpatient management.
Calculates recommended fluid type, rate and volume to correct hyponatremia slowly (or more rapidly if seizing)
Calculates pregnancy dates, forward from last period or backward from due date.
