Which medication is mentioned for use in a diabetic patient in a saline solution?

Insulin Human Regular is the medication mentioned for use in a diabetic patient in a saline solution. This form of insulin is often used in hospital settings for the management of blood glucose levels. When administered intravenously in a saline solution, it allows for rapid onset of action, which is particularly important in acute care situations, such as when patients are unable to eat or are experiencing hyperglycemia.

While other medications like Metformin and Glargine Insulin are important in the management of diabetes, they are not typically administered as an injectable in a saline solution. Metformin is primarily used as an oral medication for long-term glycemic control, and Glargine is a long-acting insulin typically used in subcutaneous form, making them less suitable for acute saline solution administration. Levothyroxine, meanwhile, is a thyroid medication and not a treatment for diabetes, thus irrelevant in this context.
