Diabetes Type 1 Diabetes 3

Question 1

A patient with Type 1 diabetes uses an insulin pump. Which insulin is used in continuous subcutaneous insulin infusion (CSII)?

Accepted Answer

Rapid-acting insulin analog

Answer

Insulin pumps use only rapid-acting insulin analogs (e.g., lispro, aspart, glulisine) delivered continuously as basal and in boluses for meals.

Question 2

Which complication is unique to Type 1 diabetes and rarely seen in Type 2?

Accepted Answer

Diabetic ketoacidosis

Answer

DKA occurs almost exclusively in Type 1 diabetes due to absolute insulin deficiency, which drives unregulated ketogenesis.

Question 3

What is the carbohydrate-to-insulin ratio used for in Type 1 diabetes management?

Accepted Answer

Calculating mealtime bolus insulin doses

Answer

The carbohydrate-to-insulin ratio (e.g., 1 unit per 15g carbs) is used to calculate how much rapid-acting insulin to take with each meal.

Question 4

Which finding on urinalysis is an early marker of diabetic nephropathy in Type 1 diabetes?

Accepted Answer

Microalbuminuria (30–300 mg/day)

Answer

Microalbuminuria (moderately increased albuminuria) is the earliest clinical marker of diabetic nephropathy and indicates glomerular damage.

Question 5

How does exercise typically affect blood glucose in a patient with Type 1 diabetes during aerobic activity?

Accepted Answer

Generally decreases blood glucose due to increased glucose uptake

Answer

Aerobic exercise increases muscle glucose uptake independent of insulin, which typically lowers blood glucose and may require carbohydrate supplementation.
