Introduction:If you have diabetes, self-testing your blood sugar (blood glucose) can be an important tool in managing your treatment plan and preventing long-term complications of diabetes. Blood sugar tests are performed with a portable electronic device that measures sugar levels in a small drop of your blood.
1. Why test your blood sugar
A. Blood sugar testing — or self-monitoring blood glucose — provides useful information for diabetes management. It can help you:
B. Judge how well you're reaching overall treatment goals
Understand how diet and exercise affect blood sugar levels
Understand how other factors, …show more content…
such as illness or stress, affect blood sugar levels
Monitor the effect of diabetes medications on blood sugar levels
Identify blood sugar levels that are dangerously high or low
2.When to test your blood sugar
A.
Your doctor will advise you on how often you should check your blood sugar level. In general, the frequency of testing depends on the type of diabetes you have and your treatment plan.
B. Type 1 diabetes. Your doctor may recommend blood sugar testing three or more times a day if you have type 1 diabetes. Testing may be before and after certain meals, before and after exercise, before bed, and occasionally during the night. You may also need to check your blood sugar level more often if you are ill, change your daily routine or begin a new medication.
C. Type 2 diabetes. If you take insulin to manage type 2 diabetes, your doctor may recommend blood sugar testing one or more times a day, depending on the number of insulin doses you take. Testing is commonly done before meals, after fasting for at least eight hours and sometimes after meals if instructed by your provider. If you manage type 2 diabetes with noninsulin medications or with diet and exercise alone, you may not need to test your blood sugar daily.

A. Supplies needed for the glucose test are:Gloves,Goggles,Safety lancet,Alcohol swabs,Glucose analyzer,Adhesive strip,Gauze,Control solutions for glucose analyzer,Test strips for glucose analyzer,Laboratory tissue,Cotton
balls
B.1.Assemble the supplies. RATIONALE: Organizing the supplies before the procedure ensures a more timely and professional process.
2.Identify the patient, introduce yourself, explain the procedure, and recheck the provider's orders. RATIONALE: Introducing yourself and explaining the procedure will establish a professional relationship with the patient and might help put him or her at ease. Identifying the patient and rechecking the provider's orders will ensure the proper tests will be performed on the right patient.
3.Wash hands and apply gloves. RATIONALE: Washing your hands protects the patient, and applying gloves protects you.
4.Select the puncture site on the fleshy part of the ring or middle finger, avoiding the very tip and the extreme sides. RATIONALE: The ring and middle fingers generally will have fewer calluses and less scarring. The tip and sides are more sensitive than the fleshy part.
5.Have the patient wash his or her hands in very warm water; if necessary, apply a warming pack to the fingertip, encourage the patient to relax, and provide a comfortable, professional atmosphere. RATIONALE: The patient washing his or her hands in very warm water provides two benefits: his or her hands will be cleaner and warmer, which encourages better blood to the area. Appling a warming pack to the fingertips will further encourage blood flow. A relaxed patient in a comfortable, professional atmosphere is more likely to provide a better sample.
6.Clean the selected puncture site with alcohol swab and allow it to air dry or dry it with a gauze pad. RATIONALE: Alcohol will remove any residue soap or debris. Allowing the alcohol to dry will prevent irritation and stinging. If the site is wiped dry, the irritation of the gauze pad will further encourage blood to the area.
7.Holding the distal phalange firmly, perform the puncture across the lines of the fingerprint rather than along the lines. RATIONALE: Holding the distal phalange firmly will add support to the finger and prevent the patient from pulling back on the finger during the puncture. Puncturing across the fingerprint will assist the blood to form a drop rather than flow across the fingertip.
8.Using a gauze pad, wipe away the first drop. RATIONALE: The first drop usually contains contamination from the alcohol and tissue fluid and would not be a good representation of the blood sample needed. Using gauze rather than cotton to wipe it away lessens the likelihood of it clotting too quickly.
9.Collect the specimen according to the test being performed (see Chapter 41 for hemoglobin and hematocrit;
10.Have patient hold firm, direct pressure on the site with a cotton ball for at least 2 minutes. If the bleeding has stopped, an adhesive strip can be applied. If the bleeding has not stopped yet, hold firm, direct pressure on the site for another 5 minutes and then recheck. Adhesive strips are not recommended for patients younger than 2 years. RATIONALE: A cotton ball is used because the cotton fibers further encourage clotting at the puncture site. The bleeding should be stopped before the patient leaves your care. Adhesive strips for children younger than 2 years are not recommended because they are a choking hazard.
11.Disinfect the area and equipment, remove gloves, and dispose of them into a biohazard waste container/red bag. Wash hands. RATIONALE: Biohazard waste should be controlled for everyone's protection. Hand washing after removing gloves further protects you.
12.Record the procedure and complete the laboratory requisition or test. The laboratory requisition is completed in the presence of the patient if possible. RATIONALE: Documentation is critical for good patient records. Completing the laboratory requisition in the presence of the patient provides accurate insurance and personal information if needed for the insurance forms and for your medical records.
