. The following results were obtained on a patient's serum.

 

Sodium: 142 mmol/L

Potassium: 4.3 mmol/L

Chloride: 101 mmol/L

Bicarbonate: 28 mmol/L

Measured Osmolality: 314 mOsm/kg (normal 289-308)

Glucose: 283 mg/dL

BUN: 70 mg/dL

 

Considering this data, which of the following statements is true?

 

a. The electrolytes are in balance (normal anion gap), but the measured osmolality does not correlate with the calculated osmolality

b. The electrolytes are in balance (normal anion gap), and the measured osmolality correlates with the calculated osmolality

c. The electrolytes are not in balance (low anion gap), but the measured osmolality correlates with the calculated osmolality

d. The electrolytes are not in balance (high anion gap) and the measured osmolality does not correlate calculated osmolality
