Which treatment approach involves delivering a continuous subcutaneous insulin infusion using an insulin pump and providing bolus doses before meals to mimic physiologic insulin secretion?
Oral antidiabetic medication therapy.
Basal-bolus insulin therapy.
Sliding-scale insulin therapy.
Insulin glargine therapy.
The Correct Answer is B
Basal-bolus insulin therapy involves administering a continuous basal insulin infusion to provide background insulin coverage and delivering bolus doses of insulin before meals to cover postprandial glucose elevations.
Incorrect choices:
a. This choice is incorrect. Oral antidiabetic medications are not used in basal-bolus insulin therapy.
c. This choice is incorrect. Sliding-scale insulin therapy involves adjusting insulin doses based on current blood glucose levels, rather than providing consistent basal and mealtime coverage.
d. This choice is incorrect. Insulin glargine therapy provides long-acting basal insulin coverage but does not involve bolus doses before meals.

Correct Answer is A
Explanation
Correct choices
A. The pancreas plays a central role in blood glucose regulation by releasing glucose into the bloodstream through glycogenolysis and gluconeogenesis when blood glucose levels are low. It also stores glucose as glycogen and responds to insulin and glucagon signals.
Incorrect choices:
b. This choice is incorrect. While the kidneys play a role in filtering blood and excreting waste products, they are not primarily responsible for regulating blood glucose levels.
c. This choice is incorrect. The lungs are involved in oxygen and carbon dioxide exchange and are not directly involved in blood glucose regulation.
d. This choice is incorrect. The spleen is involved in immune function and blood filtration, but it does not play a central role in blood glucose regulation.
Correct Answer is C
Explanation
Insulin plays a key role in glucose metabolism by facilitating the uptake of glucose into cells, reducing blood sugar levels. It also promotes glycogen synthesis in the liver and muscle cells.
Incorrect choices:
a. This choice is incorrect. Insulin promotes glucose uptake into cells, leading to decreased blood sugar levels.
b. This choice is incorrect. Insulin promotes glycogen synthesis, which stores glucose and reduces blood sugar levels.
d. This choice is incorrect. Insulin promotes glycogen synthesis, contributing to the storage of glucose and lowering blood sugar levels.
