A nurse is teaching about self-monitoring to a client who has type 1 diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?
"I will check my urine once a day for ketones."
"I will check my blood glucose every 4 hours when I am sick."
"I will notify my provider if pre-meal glucose is 120 mg/dL."
"I will check blood glucose every 5 minutes when lightheaded."
The Correct Answer is B
A. Checking urine for ketones is generally recommended when blood glucose is consistently high, but once daily may not be sufficient during illness or hyperglycemic episodes.
B. Monitoring blood glucose every 4 hours during illness helps manage potential fluctuations and prevent diabetic ketoacidosis, making this statement correct.
C. A pre-meal blood glucose of 120 mg/dL is within the acceptable range, so notifying the provider is unnecessary.
D. Checking blood glucose every 5 minutes is excessive and not standard practice, even if feeling lightheaded.
