Question

A client with a tentative diagnosis of hyperosmolar hyperglycemic nonketotic syndrome (HHNS) has a history of type 2 diabetes that is being controlled with an oral diabetic agent, tolazamide. Which laboratory test is the most important for confirming this disorder?

Answer 1

Answer:

The correct answer is - serum osmolarity.

Explanation:

Serum osmolarity is one of the essential laboratory tests for diagnosing the hyperosmolar hyperglycemic nonketotic syndrome or HHNS. This test also helps to determine strategies for the treatment and evaluation range for HHNS.

Serum osmolarity of HHNS patients typically falls in the range of 350 mOsm/L or more. There is another test also available but serum osmolarity is very important in confirming a diagnosis of HHNS.

Thus, the correct answer is - serum osmolarity.
