Correct Answer: A

Rationale: In this scenario where the client with type I diabetes mellitus is exhibiting confusion, light-headedness, and aberrant behavior, indicating hypoglycemia, the first-line treatment would be administering I.M. or subcutaneous glucagon. Glucagon helps to rapidly increase blood sugar levels by stimulating the liver to release stored glucose. This is crucial in situations where the client is conscious but unable to take oral carbohydrates, such as in cases of severe hypoglycemia with altered mental status. Administration of glucagon helps to quickly raise blood sugar levels and prevent further deterioration in the client's condition. Options B, C, and D are not the initial interventions in this situation and may not be as effective in rapidly correcting hypoglycemia in a client who is exhibiting signs of confusion and aberrant behavior.
