After the most recent physician's office visit and blood work, the patient learns that an oral glucose tolerance test scheduled for the next week is not needed. The patient says to the nurse, This is good news if I don't need additional testing.

What should the nurse recognize that the cancellation of this test indicates?
1. consistently high fasting blood glucose levels
2. no evidence of type 1 diabetes mellitus
3. normal renal functioning
4. normal liver functioning

Question 2

Answer to Question 1

Correct Answer: 1
An oral glucose tolerance test is done to diagnose diabetes mellitus if prior fasting blood sugar levels are inconsistent. However, the test will not be done if the patient's fasting blood sugars are consistently high or greater than 200 mg/dL. Cancellation of the test does not indicate absence of evidence of type 1 diabetes, or normal liver or renal function.

Answer to Question 2

Correct Answer: 2, 3, 4
Beta cells produce insulin, which facilitates the uptake and use of glucose by muscle, liver, and fat cells and prevents an excessive breakdown of glycogen in the liver and muscle. Delta cells secrete somatostatin, which inhibits the secretion of glucagon and insulin by the alpha and beta cells. Alpha cells produce glucagon, which decreases glucose oxidation and promotes an increase in the blood glucose level by signaling the liver to release glucose from glycogen stores. F cells secrete pancreatic polypeptide, which is believed to inhibit the exocrine activity of the pancreas and has no impact on the regulation of blood glucose. The pancreas does not have omega cells.
