A patient with diabetes has a capillary glucose level of 240 mg/dL (13.3 mmol/L) before exercise and reports nausea. Which action should the nurse take before allowing exercise?
Correct answer: B. Check urine or blood ketones before exercise
- A. Encourage vigorous exercise to lower the glucose
- B. Check urine or blood ketones before exercise
- C. Give the patient a high-fat snack immediately
- D. Tell the patient to omit the next insulin dose
Explanation
Hyperglycaemia with nausea may indicate developing ketone production, and exercise can worsen metabolic acidosis when insulin is insufficient. Ketones should be checked before activity and the patient assessed for further symptoms. Vigorous exercise, omitting insulin and giving a high-fat snack are unsafe responses.
