Which of the following is a guideline for assessing a patient before insulin therapy?

Assessing a patient before initiating insulin therapy involves understanding several critical components of their health and readiness to manage their diabetes effectively. Evaluating a patient's understanding of insulin is essential because it ensures that they comprehend how insulin works, the importance of adhering to prescribed doses, and the potential effects on their blood sugar levels. This knowledge is vital for empowering patients to manage their condition proactively, recognize signs of hypo- or hyperglycemia, and make informed decisions regarding their healthcare.

In contrast, while it may be beneficial to know about a patient's dietary habits, such as their favorite foods, this is not a primary guideline for assessing their readiness for insulin therapy. Focusing solely on measuring blood pressure neglects other vital metrics, such as blood glucose levels and overall health considerations, which are critical in the context of insulin administration. Finally, administering insulin without considering a patient's health status poses significant risks, as it could lead to adverse effects, including hypoglycemia or other complications. Consequently, assessing a patient’s understanding of insulin plays a crucial role in ensuring safe and effective therapy.
