A person with type 1 diabetes plans to run a half-marathon. What proactive blood sugar strategy is most recommended?
Answer: Reduce basal/bolus insulin and increase carbohydrate intake around the event
Reducing insulin and increasing carbohydrate intake around prolonged exercise helps prevent exercise-induced hypoglycemia.
What is the primary reason blood glucose should be checked before driving for a person with insulin-treated diabetes?
Answer: Hypoglycemia impairs cognitive function and reaction time, creating accident risk
Hypoglycemia reduces alertness and reaction time, making driving dangerous; a pre-drive check ensures glucose is in a safe range.
Which insulin storage rule is critical to maintain potency?
Answer: Open insulin vials in use can be kept at room temperature for up to 28–30 days
Most insulin formulations can be kept at room temperature for 28–30 days after opening without significant loss of potency.
What is 'glycemic variability' and why does it matter beyond A1C?
Answer: Fluctuations in blood glucose levels throughout the day, which increase oxidative stress and complication risk
High glycemic variability, even with an acceptable A1C, increases oxidative stress and is associated with greater diabetes complication risk.
In a patient with hypoglycemia unawareness, what is the recommended treatment approach?
Answer: Raise the blood glucose targets temporarily to restore hypoglycemia awareness
Deliberately relaxing glucose targets to prevent hypoglycemia allows counter-regulatory hormone responses to recover, restoring awareness.
Which carbohydrate counting approach is used in intensive insulin therapy to match bolus insulin precisely to meal intake?
Answer: Insulin-to-carb ratio (ICR)
The insulin-to-carb ratio defines how many grams of carbohydrate one unit of rapid-acting insulin will cover.
Which of the following best describes 'reactive hypoglycemia'?
Answer: Blood sugar drop 1–3 hours after a high-carbohydrate meal due to excessive insulin response
Reactive hypoglycemia is a postprandial drop in blood glucose caused by an exaggerated insulin response to carbohydrate intake.
