How should insulin vials be stored?
Store insulin vials in the freezer to prolong shelf life.
Store insulin vials at room temperature away from direct sunlight.
Store insulin vials in the refrigerator and warm them before injection.
Store insulin vials in a hot environment to prevent crystallization.
The Correct Answer is B
Store insulin vials at room temperature away from direct sunlight. Refrigeration is generally not necessary for most insulin types when in use, and freezing or exposure to high temperatures can damage insulin.
Incorrect choices:
a. Freezing insulin can alter its efficacy and should be avoided.
c. Insulin stored in the refrigerator should not be warmed before injection, as this can lead to temperature-related degradation.
d. Storing insulin in a hot environment can lead to degradation and loss of effectiveness.

Correct Answer is D
Explanation
Basal insulin is typically administered once or twice daily to mimic the body's basal insulin secretion and maintain stable blood glucose levels between meals and overnight.
Incorrect choices:
a. Basal insulin is not administered before meals; it is intended to regulate fasting glucose levels.
b. Basal insulin does not cover carbohydrates consumed in meals; it targets basal glucose levels.
c. Rapid-acting insulin is not synonymous with basal insulin; they serve different purposes in insulin therapy.
Correct Answer is C
Explanation
Basal insulin is typically taken once or twice a day to provide a steady baseline level of insulin, while prandial (mealtime) insulin is taken before meals to control post-meal blood sugar spikes.
Incorrect choices:
a. Basal insulin indeed provides a steady amount of insulin to cover the body's basic metabolic needs between meals and overnight. This statement is correct.
b. Prandial insulin does help control the rise in blood sugar after meals. This statement is correct.
d. Prandial insulin is indeed a type of rapid-acting insulin used to cover meals and control post-meal blood sugar levels. This statement is correct.
