A blood glucose test is given to determine the amount of glucose, which is a kind of sugar, that is residing in a patient’s blood. Glucose is attained through carbohydrates and is an important energy source for any body. Insulin is what assists your body’s cells in breaking down and utilizing the glucose. If your blood glucose levels become too high, over time they can cause damage to your blood vessels, your nerves, your kidneys, and your eyes. Remember to identify the patient, wash your hands and gather equipment, and explain what is happening to your patient. Any finger will do for the prick, but be sure to use the lateral side of the finger, and massage the digit to increase blood flow to the tip before taking any blood. Once the massage is complete, use an alcohol swab to cleanse the area. Prick the side of the finger, swipe away the first drop of blood with a cotton ball, and then squeeze the finger to produce a second drop of blood for testing. Place the drop of blood on the strip, and set aside. While the machine calculates, apply pressure to the prick point for at least one minute and wipe away any extra blood with a cotton ball. Once the bleeding has ceased, apply a band-aid or plaster as needed. Be sure to throw away the lancet you used for pricking as well as your gloves, and don’t forget to wipe down your machine with an alcohol swab.
