Question 1 of 5
The nurse explains that the negative feedback inhibition controls hormone release by communication between which two anatomical areas?
Correct Answer: A
Rationale: The amount of hormone released is controlled by negative feedback inhibition. The negative feedback inhibition process is when a gland releases a primary hormone, which stimulates target cells to release a secondary hormone; the gland slows the release of the primary hormone as it senses the rise of the secondary hormone. Information is constantly being exchanged via the bloodstream between target organs and endocrine glands.
Question 2 of 5
Which diagnostic test for diabetes mellitus provides a measure of glucose levels for the previous 8 to 12 weeks?
Correct Answer: C
Rationale: Glycosylated hemoglobin (HbA1c) - This blood test measures the amount of glucose that has become incorporated into the hemoglobin within an erythrocyte. Because glycosylation occurs constantly during the 120-day lifespan of the erythrocyte, this test reveals the effectiveness of diabetes therapy for the preceding 8 to 12 weeks.
Question 3 of 5
Which test will furnish immediate feedback for a newly diagnosed diabetic who is not yet under control?
Correct Answer: A
Rationale: Diabetics should do a finger-stick blood glucose level test before each meal and at bedtime each day until their disease is under control. The HbA1c serum test reveals the effectiveness of diabetes therapy for the preceding 8 to 12 weeks.
