diabetesnclexquestions

This set of Diabetes NCLEX questions is intended to help nurses brush up on the concepts of managing patients with this chronic disease.

The topic of diabetes mellitus care and management is one of the most challenging ones that nurses face because you are expected to know about the disease process and how to ensure that the patient will have the ability to function optimally in the face of chronic illness.

Questions asked mostly consist of patient education, medication administration, determining signs and symptoms of diabetic emergencies, and complications of the disease process. These topics are included in this practice test to help you understand care for these patients with diverse and sometimes specialized care requirements.

Read and analyze each question carefully and chose the best answer/s from the choices provided. At the end of this practice tests, correct answers along with the explanation are given.
