Question 1

During exercise, a patient's CGM shows glucose dropping from 140 to 95 mg/dL over 30 minutes with a downward arrow. Per ADA exercise guidelines, what should the patient do?

Accepted Answer

Consume 15–30g fast-acting carbohydrates and continue or pause exercise

Answer

ADA exercise guidelines recommend consuming 15–30g of fast-acting carbohydrates when glucose falls rapidly during exercise to prevent hypoglycemia.

Question 2

Which statement about continuous glucose monitor (CGM) sensor accuracy during the warm-up period is correct?

Accepted Answer

Most CGM sensors require a 1–2 hour warm-up before providing reliable readings

Answer

Most CGM sensors require a 1–2 hour initialization/warm-up period after insertion before glucose readings are sufficiently accurate for clinical use.

Question 3

A hospitalized patient on insulin drip has fingerstick BG of 52 mg/dL but appears clinically well without symptoms. What is the most appropriate next step?

Accepted Answer

Repeat the fingerstick immediately and treat if confirmed

Answer

In the hospital, a low fingerstick result without symptoms warrants immediate repeat testing to confirm hypoglycemia before treatment, as capillary samples can yield erroneous results.

Question 4

Which CGM alarm threshold setting is most appropriate to help a patient with hypoglycemia unawareness?

Accepted Answer

Low alarm at 80 mg/dL with a predictive low alert at 20 minutes

Answer

Setting a low alarm at 80 mg/dL with a predictive alert provides early warning for patients with impaired hypoglycemia awareness, allowing intervention before glucose falls to dangerous levels.

Question 5

A patient's CGM Mean Absolute Relative Difference (MARD) is reported as 12%. What does this indicate?

Accepted Answer

On average, CGM readings differ from reference blood glucose by 12%

Answer

MARD is the standard CGM accuracy metric; a 12% MARD means CGM values deviate from reference glucose by an average of 12%, which is within acceptable clinical accuracy range.
