Which of the following stimulates the pancreas to secrete insulin?

Ketoacids

Hyperglycemia

Hypoglycemia

Glucagon

Answer and Explanation

The Correct Answer is B

A. Ketoacids: This is incorrect. While ketoacids are a by-product of fat metabolism that occurs when insulin is low, they do not directly stimulate insulin secretion.
B. Hyperglycaemia: This is correct. Elevated blood glucose levels (hyperglycaemia) directly stimulate the pancreas to secrete insulin to help lower blood glucose levels.
C. Hypoglycaemia: This is incorrect. Low blood glucose levels (hypoglycaemia) would reduce insulin secretion and might increase glucagon secretion to raise blood glucose levels.
D. Glucagon: This is incorrect in the context of directly stimulating insulin secretion. Glucagon is a hormone secreted by the alpha cells of the pancreas when blood glucose levels are low. Its primary role is to increase blood glucose levels by stimulating glycogenolysis and gluconeogenesis in the liver.

Explanation

A. Subcutaneous: Correct. The most common route for insulin administration is subcutaneous injection.
B. Intradermal: Incorrect. Insulin is not administered intradermally as this route does not provide proper absorption.
C. Oral: Incorrect. Insulin is not given orally because it would be broken down by digestive enzymes and stomach acid before it could be effective.
D. Intravenous: Correct. Insulin can be administered intravenously in emergency situations, such as diabetic ketoacidosis.
E. Topical: Incorrect. Insulin is not effective when applied topically.

Correct Answer is ["0.6"]

Explanation

To calculate the volume of diazepam to administer, we use the formula:
Volume (mL)=Dose (mg)÷Concentration (mg/mL)
Given:
● Dose = 3 mg
● Concentration = 5 mg/mL
Plugging these values into the formula:
Volume (mL)=3 mg÷5 mg/Ml
Volume (mL)=0.6 mL
So, the nurse should administer 0.6ml of diazepam.
