Final answer:
The critical thinking attitude that a nurse would apply in questioning the order to administer metformin to a Type 1 diabetic is skepticism.
Step-by-step explanation:
The critical thinking attitude that a nurse would be applying in questioning the order to administer metformin to a Type 1 diabetic is skepticism.
Metformin is a medication commonly used to treat Type 2 diabetes, not Type 1 diabetes. Type 1 diabetes is characterized by an absolute deficiency of insulin, while Type 2 diabetes involves insulin resistance and impaired insulin secretion. Administering metformin to a Type 1 diabetic may not be effective and could potentially be harmful.
Therefore, a nurse must critically evaluate the order and question its appropriateness to ensure the safety and well-being of the patient.
