Final answer:
The nurse is using practical training or demonstration to teach a diabetic patient how to administer insulin. This hands-on method is essential for diabetic patients, particularly those with type 1 diabetes.
Step-by-step explanation:
The mode of learning that the nurse is using when showing a diabetic patient how to draw insulin out of a syringe is practical training or demonstration. This hands-on approach is crucial for patients with diabetes, especially those with type 1 diabetes, who need to self-administer insulin injections to manage their blood sugar levels. Insulin is necessary for the transport and storage of glucose, which helps to decrease blood glucose levels after a meal high in glucose. Thanks to the development of biotechnology, human insulin can now be synthesized and purchased by diabetic patients, offering a safer and more effective treatment option than previous alternatives.
