Nursing Skills | Blood Glucose Monitoring

Blood glucose monitoring is a vital nursing skill used to assess metabolic status, guide insulin therapy, and detect hypo or hyperglycemia. Nurses begin by verifying provider orders, confirming patient identity, and assessing factors that may influence glucose levels such as meals, medications, stress, or illness. The procedure involves preparing the glucometer, using a clean lancet, obtaining a capillary blood sample, and applying it to the test strip. Proper site selection and rotation help prevent skin irritation. Nurses must follow infection control practices, including wearing gloves and disposing of sharps safely. Interpretation of results requires understanding normal ranges, trends, and patient specific targets. Abnormal values may require immediate intervention, such as administering insulin or providing carbohydrates. Documentation includes the glucose value, time of testing, related symptoms, and any interventions performed. Patient education is essential, especially for those managing diabetes at home.
