A client with type 1 diabetes arrives for a training session and checks her blood glucose, which reads 265 mg/dL. She mentions she has ketone test strips in her bag. What is the most appropriate action before proceeding with exercise?
Why each option is right or wrong
Pick an answer. Then tap any option to read its explanation, the wrong ones included.
A — Correct. With glucose above 250 mg/dL in type 1 diabetes, check ketones first. If they are present, exercise can worsen ketoacidosis, so hold the session and refer.
B — Not this one. This uses the wrong cutoff: ketones plus glucose above 250 mg/dL is already a stop signal, and waiting for 300 is unsafe.
C — Not this one. Hard intervals are not a tool for lowering high glucose. Vigorous work can push glucose up further in type 1 diabetes, and the trainer is not managing blood sugar.
D — Not this one. Light exercise is still exercise. If ketones have not been checked, the safe order is to test first, not to start moving and recheck.
E — Not this one. The 300 mg/dL figure is not the deciding threshold here. Above 250 mg/dL, ketone status decides whether exercise is safe.
