# RC16A — Patient Context Expansion and Universal Autofill

## Expanded parser

The active patient context now recognizes and retains:

- sodium
- potassium
- chloride
- bicarbonate/CO2
- BUN
- creatinine and creatinine trend
- glucose
- calcium
- magnesium
- phosphate
- albumin
- WBC
- hemoglobin
- hematocrit
- platelets
- INR
- aPTT
- AST
- ALT
- bilirubin
- alkaline phosphatase
- LDH
- uric acid
- lactate
- ANC
- osmolality
- troponin
- eGFR
- phenytoin level
- vancomycin level
- iron, TIBC, ferritin
- pH
- beta-hydroxybutyrate
- acetaminophen level
- digoxin level
- heart rate
- respiratory rate
- temperature
- oxygen saturation
- QT and QTc
- systolic and diastolic blood pressure

Blood pressure is stored as two atomic values. Explicit Fahrenheit temperatures are converted to the canonical Celsius patient-context value while preserving the raw captured line.

Each captured result continues to retain value, unit, timestamp when available, capture number, source, confidence, and raw text.

## Additional automatic calculator population

RC16A adds patient-context population to:

- acetaminophen toxicity/NAC
- anticoagulant reversal
- digoxin immune Fab
- DKA treatment support
- CRRT solution/electrolyte support
- TNK stroke support
- HIV/occupational exposure PEP
- RSI dosing

RC15 bindings remain active for CrCl, body weight, corrected calcium, iron deficit, QTc, anion gap, sodium, aminoglycosides, vancomycin, and antibiotic/allergy support.

## Compact patient strip

Bound calculator windows display a compact context strip such as:

`68 yr · Male · 82.4 kg · SCr 1.31 · K 5.2 · Allergies Penicillin`

This is informational, nonmodal, and does not force the window above other applications.

## Window behavior

No standard PhUCKIT window uses AlwaysOnTop. Calculator values are populated when a tool opens, remain editable, and do not trap workflow.

## Preservation

RC16A preserves the RC14.1 installation safeguards and RC15 owner database, active truth bundles, Patient Data Bindings, custom records, exports, logs, and backups.
