A patient with severe hypoglycaemia is unconscious but has a functioning intravenous line. Which treatment provides rapidly available glucose?
Correct answer: A. Intravenous dextrose
- A. Intravenous dextrose
- B. Intramuscular vitamin K
- C. Oral glucose tablets
- D. Subcutaneous insulin
Explanation
Intravenous dextrose is appropriate for an unconscious patient with confirmed intravenous access because it raises blood glucose rapidly. Oral glucose is unsafe in an unconscious patient, while insulin would worsen hypoglycaemia.
