You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.


  • Hypoglycemic medicine may be given to decrease the amount of sugar in your blood. It helps your body move the sugar to your cells, where it is needed for energy.
  • Insulin may be given to decrease the amount of sugar in your blood. You may be given 1 or more doses of insulin each day. This medicine may be given through an IV or as an injection.


  • Blood glucose checks will happen several times throughout the day. Your blood will be tested with a glucose monitor.
  • Intake and output measurement means that your healthcare provider needs to know how much liquid you are getting and urinating. You may need to urinate into a container in bed. A healthcare provider will then measure the amount you urinated. Do not flush urine down the toilet before you ask your healthcare provider.
  • Vital signs will be checked throughout the day. Vital signs are your blood pressure, heart rate, breathing rate, and temperature. Healthcare providers will also ask about your pain. Vital signs give healthcare providers information about your current health.


  • Blood tests may be done to test ketones, sugar, and electrolyte levels. You may need to have blood drawn more than once.
  • A urine test may be done to check the amount of ketones and sugar it contains.
  • An A1c test may be done to check the average amount of sugar in your blood over the past 2 to 3 months.
  • An arterial blood gas (ABG) test checks the amount of acid in your blood. It also checks the amount of gases, such as oxygen and carbon dioxide.


You may receive liquids through an IV that is placed in your vein to treat dehydration. The liquids may also include electrolytes, such as potassium.


  • Treatment may cause your blood sugar level to become too low. The levels of your electrolytes (minerals) may become too high or too low. For example, your blood level of potassium may decrease.
  • Without treatment, high blood sugar levels can lead to severe dehydration. If you have surgery, you may develop an infection in your surgery wound, or it may not heal well. You may get a blood clot in your leg or arm. The clot may travel to your heart or brain and cause life-threatening problems, such as a heart attack or stroke. Hyperglycemia may cause pancreatitis. Hyperglycemia can also lead to diabetes. Hyperglycemia can damage your nerves, veins, arteries, and organs over time. Damage to arteries may increase your risk for a heart attack or stroke.


You have the right to help plan your care. Learn about your health condition and how it may be treated. Discuss treatment options with your caregivers to decide what care you want to receive. You always have the right to refuse treatment.
