Diabetes Insulin Therapy 4

Question 1

An insulin-dependent patient plans to travel across multiple time zones. Which insulin type requires the most careful schedule adjustment?

Accepted Answer

Long-acting basal insulin

Answer

Long-acting basal insulin is time-sensitive; crossing time zones can disrupt the 24-hour dosing cycle, requiring careful scheduling to avoid gaps or overdose.

Question 2

Which of the following best describes insulin resistance in Type 2 diabetes?

Accepted Answer

Cells do not respond effectively to insulin's signal to take up glucose

Answer

Insulin resistance means peripheral tissues (muscle, fat, liver) fail to respond normally to insulin signaling, requiring higher insulin levels to achieve glucose uptake.

Question 3

A closed-loop insulin delivery system (artificial pancreas) differs from standard CSII by:

Accepted Answer

Automatically adjusting insulin delivery based on continuous glucose monitor readings

Answer

Closed-loop systems integrate a CGM with an insulin pump and algorithm to automatically modulate basal insulin delivery in real time.

Question 4

Inhaled insulin (Afrezza) is contraindicated in patients with:

Accepted Answer

Chronic lung disease such as COPD or asthma

Answer

Afrezza is contraindicated in patients with chronic lung disease because it can cause acute bronchospasm and decreased pulmonary function.

Question 5

What is the correct action if a patient accidentally injects double their usual insulin dose?

Accepted Answer

Consume carbohydrates immediately and monitor glucose closely

Answer

Immediate carbohydrate intake and close glucose monitoring are required to prevent or treat the hypoglycemia that will result from the excess insulin.
