NUR 1101: Blood Glucose Monitoring in Nursing Skills

Blood Glucose Monitoring Essentials

• A glucometer is essential for measuring blood glucose levels.
• Blood glucose reagent/test strips must be compatible with the specific glucometer used.
• Other necessary supplies include lancets, gauze, alcohol swabs, band-aids, disposable gloves, and a clean kidney receiver.

Procedure Implementation

• Review the doctor’s order to understand test purpose.
• Confirm the patient’s identity to ensure accurate testing.
• Explain the procedure to the patient to obtain consent and cooperation.
• Perform hand hygiene and don gloves before the procedure.

Choosing a Puncture Site

• Select a vascular site, typically on the sides of the fingers.
• Avoid sites that are cold, cyanotic, swollen, inflamed, infected, or wounded.
• Rotate puncture sites with each test to minimize tissue damage.
• Disinfect the chosen site with an alcohol swab and let it air dry completely.

Preparing for Blood Sample Collection

• Prepare the glucometer and check the expiry dates of test strips and lancets.
• Verify the code number of test strips if required, ensuring it matches the glucometer.
• Insert the test strip into the glucometer, checking compatibility.

Collecting a Blood Sample

• Determine the appropriate depth for puncture.
• Firmly position the lancet at a perpendicular angle to the fingertip.
• Execute a quick, deliberate puncture to promote effective blood flow.
• Apply a drop of blood to the test strip’s testing area.
• After sample collection, apply pressure to the puncture site to stop bleeding.

Post-Procedure Actions

• Read and document the glucose level result.
• Inform the patient about their results promptly.
• Discard the used lancet in a sharps container and dispose of the test strip properly.
• After bleeding stops, apply a bandage to the puncture site.
• Remove gloves and perform hand hygiene.

Evaluation and Documentation

• Ensure bleeding from the puncture site has fully stopped.
• Record results and take necessary actions based on findings.

Important Notes

• Blood glucose is typically measured in mmol/L or mg/dL.
• Glucose control solutions can be used to test the functionality of glucometers and strips.

Learning Outcomes for Nursing Students

• Students will describe indications for measuring capillary blood glucose levels.
• They will learn to measure current blood glucose levels effectively.
• Understand that frequent monitoring is key for patients at risk of hyperglycemia or hypoglycemia.
• Evaluate treatment effectiveness through routine testing and patient education on procedures.

Considerations for Assessment and Planning

• Assess patient’s need for glucose monitoring, prior readings, and frequency required.
• Evaluate the condition of the skin at puncture sites, ensuring proper circulation and sensation.
• Plan the test timing relative to meals and the overall patient condition.
