A client's serum chemistry measurements are serum sodium level 146 mEq/L, BUN 24 mg/dl, and glucose level 90 mg/dl. What is the client's serum osmolality?
 
  a. 275 mOsm/kg
  b. 285 mOsm/kg
  c. 295 mOsm/kg
  d. 305 mOsm/kg

ANS: D
To calculate osmolality, use the equation:
2(serum Na concentration) + BUN/3 + glucose level/18.
2(146) + 24/3 + 90/18 = 305 mOsm/kg.
