In hyperosmolar hyperglycemic syndrome, the laboratory results are similar to those of diabetic ketoacidosis, with three major exceptions. What differences would you expect to see in patients with hyperosmolar hyperglycemic syndrome?
a. Lower serum glucose, lower osmolality, and greater ketosis
b. Lower serum glucose, lower osmolality, and milder ketosis
c. Higher serum glucose, higher osmolality, and greater ketosis
d. Higher serum glucose, higher osmolality, and no ketosis
D
In patients with hyperosmolar hyperglycemic syndrome (HHS), glucose is higher; osmotic diuresis is greater, resulting in higher osmolality; and ketosis is usually absent. Glucose values in HHS are typically higher than those of diabetic ketoacidosis and are not typically accompanied by ketosis.
