- 1. 1-800-DIABETES www.diabetes.org DIABETES CARE TASKS AT SCHOOL: What Key Personnel Need to Know KETONES
- 2. 1-800-DIABETES www.diabetes.org 2 Goal: Optimal Student Health and Learning Ketone Monitoring is a vital piece of a comprehensive plan.
- 3. 1-800-DIABETES www.diabetes.org 3 Learning Objectives Participants will be able to understand: • What ketones are • Why ketones are monitored • When ketones should be monitored • When to contact school nurse, parent/guardian, health care provider Participants will be able to demonstrate: • How to perform a ketone test
- 4. 1-800-DIABETES www.diabetes.org 4 What Are Ketones? • Acids that result when the body does not have enough insulin and uses fats for energy • May occur when insulin is not given, during illness or extreme bodily stress, or with dehydration • Can cause abdominal pain, nausea, and vomiting • Without sufficient insulin ketones continue to build up in the blood and result in diabetic ketoacidosis (DKA)
- 5. 1-800-DIABETES www.diabetes.org 5 Why Test for Ketones? • DKA is a critical emergency state • Early detection and treatment of ketones prevents diabetic ketoacidosis (DKA) and hospitalizations due to DKA • Untreated, progression to DKA may lead to severe dehydration, coma, permanent brain damage, or death • DKA is the number one reason for hospitalizing children with diabetes
- 6. 1-800-DIABETES www.diabetes.org 6 When Should Ketones Be Checked? The DMMP should specify, generally: • When blood glucose remains elevated • During acute illness, infection or fever • Whenever symptoms of DKA are present ─ Nausea ─ Vomiting or diarrhea ─ Abdominal Pain ─ Fruity breath odor • Common symptoms including fruity odor to breath, nausea, vomiting, drowsiness, abdominal pain − Rapid breathing − Thirst and frequent urination − Fatigue or lethargy
- 7. 1-800-DIABETES www.diabetes.org 7 How Quickly Does DKA Progress? • An isolated high blood glucose reading, in the absence of other symptoms is not cause for alarm • DKA usually develops over hours, or even days • DKA can progress much more quickly for students who use insulin pumps, or those who have an illness or infection • Most at risk when symptoms of DKA are mistaken for flu and high blood glucose is unchecked and untreated
- 8. 1-800-DIABETES www.diabetes.org 8 Checking for Ketones • Urine testing ─ Most widely used method • Blood testing ─ Requires a special meter and strip ─ Procedure similar to blood glucose checks
- 9. 1-800-DIABETES www.diabetes.org 9 1. Gather supplies 2. Student urinates in clean cup 3. Put on gloves, if performed by someone other than student 4. Dip the ketone test strip in the cup containing urine. Shake off excess urine 5. Wait 15 - 60 seconds 6. Read results at designated time 7. Record results, take action per DMMP How to Test Urine Ketones
- 10. 1-800-DIABETES www.diabetes.org 10 Test Results: Color Code no ketones trace small moderate large ketones present
- 11. 1-800-DIABETES www.diabetes.org 11 Considerations • Colors on strips and timing vary according to brand • If using a scale with “urine glucose” and “urine ketones,” be sure to read the correct scale when testing for ketones • Follow package instructions regarding expiration dates, time since opening, correct handling, etc., as incorrect results may occur
- 12. 1-800-DIABETES www.diabetes.org 12 How To Test for Blood Ketones 1. Prepare lancing device 2. Wash hands using warm soapy water and dry them completely 3. Remove the test strip from its foil packet 4. Insert the three black lines at the end of the test strip into the strip port 5. Push the test strip in until it stops
- 13. 1-800-DIABETES www.diabetes.org 13 How To Test for Blood Ketones 6. Touch the blood drop to the purple area on the top of the test strip. The blood is drawn into the test strip 7. Continue to touch the blood drop to the purple area on the top of the test strip until the monitor begins the test 8. The blood ß-Ketone result shows on the display window with the word KETONE
- 14. 1-800-DIABETES www.diabetes.org 14 Treatment of Ketones • free use of bathroom • sugar-free liquids • insulin as per DMMP • limit physical activity • if vomiting or lethargic, call parent/guardian Generally: DMMP specifies treatment for ketones for the individual student.
