Diabetes Blood Sugar Management 5

Question 1

A person with type 1 diabetes plans to run a half-marathon. What proactive blood sugar strategy is most recommended?

Accepted Answer

Reduce basal/bolus insulin and increase carbohydrate intake around the event

Answer

Skip all insulin doses on race day to prevent hypoglycemia

Answer

Increase insulin doses to handle the carb-loading before the race

Answer

Avoid all carbohydrates to keep glucose stable

Question 2

What is the primary reason blood glucose should be checked before driving for a person with insulin-treated diabetes?

Accepted Answer

Hypoglycemia impairs cognitive function and reaction time, creating accident risk

Answer

High glucose impairs night vision specifically

Answer

Glucose meters are only accurate in a stationary environment

Answer

Driving raises glucose and requires dose adjustment

Question 3

Which insulin storage rule is critical to maintain potency?

Accepted Answer

Open insulin vials in use can be kept at room temperature for up to 28–30 days

Answer

All insulin should be frozen until the day of use

Answer

Insulin should be shaken vigorously before each injection

Answer

Insulin exposed to sunlight for under an hour is still fully effective

Question 4

What is 'glycemic variability' and why does it matter beyond A1C?

Accepted Answer

Fluctuations in blood glucose levels throughout the day, which increase oxidative stress and complication risk

Answer

The difference between morning and evening A1C readings

Answer

The amount of insulin needed to lower glucose by one point

Answer

Weekly variation in fasting glucose numbers

Question 5

In a patient with hypoglycemia unawareness, what is the recommended treatment approach?

Accepted Answer

Raise the blood glucose targets temporarily to restore hypoglycemia awareness

Answer

Increase insulin doses to prevent any high glucose episodes

Answer

Avoid all exercise permanently

Answer

Switch from insulin to oral medications only

Question 6

Which carbohydrate counting approach is used in intensive insulin therapy to match bolus insulin precisely to meal intake?

Accepted Answer

Insulin-to-carb ratio (ICR)

Answer

Plate method

Answer

Glycemic index scoring

Answer

Carb elimination diet

Question 7

Which of the following best describes 'reactive hypoglycemia'?

Accepted Answer

Blood sugar drop 1–3 hours after a high-carbohydrate meal due to excessive insulin response

Answer

Low blood sugar occurring during fasting or overnight

Answer

Hypoglycemia triggered by physical activity

Answer

Low glucose caused by intentionally skipping meals
