The NLCEX likes to ask a fair amount of questions about diabetes.

Here are 10 practice questions, and this page discusses general ideas and strategy.

Diabetes NCLEX questions tend to check on your ability to understand the various aspects of both treating diabetes and the complications that arise from it.

Some key areas that it tends to focus on are:

Ketoacidosis and hypoglycemia:

Knowing the difference between ketoacidosis and hypoglycemia, as well as how to treat the two

Ketoacidosis: life threatening reaction, has hyperglycemia, dehydration, often treated with insulin and to reduce dehydration among others, monitoring intracranial pressure often important, because a too rapid blood sugar level drop can cause issues.

Patient shows up with abnormal blood sugar:

A very common NCLEX diabetes question type is: "A patient shows up with a blood sugar reading of X (either too low, too high, or normal). What should you do?"

Make sure to know how to interpret the lab value and then how to deal with all three cases.


You should be able to assess a client's knowledge of the treatment of diabetes and how to manage different attitudes towards treatment.

Specific knowledge areas commonly asked about include how often a patient should take medication, how they should respond to certain situations like a hypoglycemic event, and what a healthy diet consists of.


You're also expected to know a fair amount of the diabetes medications.

This means knowing the difference between those used for Type I vs Type II, the insulins, the sulfonylureas, and sensitizers, and so on, as well as what potential interactions they may have.

It's also good to know what dietary modifications are needed for which meds, and some other details.

Taking care of feet

Also good to know are the proper ways for a patient with diabetes to take care of their feet.
