Question 1

Which statement about insulin storage is most accurate for clinical practice?

Accepted Answer

Unopened insulin should be refrigerated; in-use insulin can be kept at room temperature up to 28–30 days

Answer

Unopened insulin should be refrigerated (36–46°F); once opened, most formulations remain stable at room temperature (up to ~77°F) for 28–30 days depending on the product.

Question 2

A patient with type 2 diabetes on premixed insulin 70/30 twice daily has good fasting glucose but high post-lunch values. The most physiologically rational adjustment is:

Accepted Answer

Add a rapid-acting insulin dose before lunch

Answer

Premixed 70/30 provides coverage mainly for breakfast and dinner; adding a separate rapid-acting dose at lunch directly addresses the uncontrolled midday postprandial rise.

Question 3

The pharmacologic rationale for combining insulin degludec with liraglutide (IDegLira) includes:

Accepted Answer

GLP-1 agonist activity mitigates insulin-associated weight gain and reduces hypoglycemia risk

Answer

GLP-1 receptor agonists promote satiety and weight loss while stimulating glucose-dependent insulin secretion, counteracting insulin-associated weight gain and reducing hypoglycemia risk.

Question 4

Insulin resistance in a hospitalized patient is MOST likely to increase insulin requirements due to:

Accepted Answer

Counter-regulatory hormone surges during physiologic stress

Answer

Physiologic stress triggers release of epinephrine, cortisol, glucagon, and growth hormone, causing marked insulin resistance and increased glucose production.

Question 5

A patient using an insulin pen forgets to prime (perform an air shot) before injection. The most likely consequence is:

Accepted Answer

Delivery of an inaccurate (smaller) insulin dose

Answer

Failure to prime the pen needle can result in air displacement within the pen mechanism, leading to delivery of less insulin than dialed.
