Question 1

A patient's CGM shows a rapid rate-of-change arrow pointing straight down (>-3 mg/dL/min). What is the most appropriate immediate action?

Accepted Answer

Recheck with fingerstick and treat hypoglycemia proactively

Answer

A rapid downward trend indicates fast-falling glucose requiring fingerstick confirmation and proactive hypoglycemia treatment before symptoms develop.

Question 2

Which factor most commonly causes falsely elevated SMBG readings in patients using older glucose meter technology?

Accepted Answer

Maltose or xylose interference with glucose oxidase strips

Answer

Maltose (found in icodextrin peritoneal dialysis solutions) and xylose can cause falsely elevated readings with glucose oxidase-based test strips.

Question 3

For a patient with T1D using a hybrid closed-loop system, when should fingerstick BG be used instead of relying solely on CGM values?

Accepted Answer

When symptoms don't match CGM reading or before treating severe hypoglycemia

Answer

Fingerstick verification is essential when symptoms are discordant with CGM values or before treating severe hypoglycemia to ensure clinical safety.

Question 4

What is the recommended minimum number of daily SMBG checks for a patient with T1D using multiple daily injections (MDI) who is NOT using CGM?

Accepted Answer

6–8 times per day

Answer

ADA standards recommend at least 6–8 SMBG checks daily for T1D patients on MDI to guide insulin dosing decisions at meals, bedtime, and overnight.

Question 5

A patient's CGM time-in-range (TIR) is 58% with 12% time below range (TBR). Which adjustment should be prioritized?

Accepted Answer

Address hypoglycemia (TBR) before attempting to improve TIR

Answer

Hypoglycemia (TBR >4%) must be addressed first as it poses immediate safety risk and may paradoxically be worsening TIR through hypoglycemia-driven rebound hyperglycemia.
