Claim: Patient B's single blood glucose reading suggests homeostasis is being maintained.\n\nEvidence: The fingerstick taken during morning lab read 92 mg/dL. A fasting blood glucose in a healthy person is generally about 70 to 99 mg/dL, and Patient B reported eating breakfast about two hours earlier, which normally keeps a reading below 140 mg/dL. The recorded value of 92 mg/dL sits inside both of those ranges.\n\nReasoning: A glucose value inside its normal range means the body's negative feedback loop for blood sugar is working. After a meal, rising glucose signals the pancreas to release insulin, which moves sugar into cells and brings the level back down; if that loop were failing, the reading would drift high and stay there. So a value near 92 mg/dL is what you would expect when insulin and glucagon are balancing each other. A limitation is that this is a single-time-point reading, so it shows a snapshot, not a trend. The exact timing of the last meal, recent exercise, or stress could each shift a one-time number, so a firm conclusion would need repeated readings across the day rather than one measurement.
