Key Actions for Medical Assistants in Blood Collection and Handling
1. Completing the Requisition Form
- Action: Verify that the requisition form has been completed.
- Rationale: Ensuring all necessary information is included prevents processing delays and errors.
2. Choosing the Right Venipuncture Method
- Scenario: Phlebotomy on an 80-year-old patient with small veins.

- Rationale: Butterfly needles provide better control and are suitable for smaller veins.
3. Managing Abnormal Blood Glucose Results
- Finding: Fasting blood glucose of 200 mg/dL.
- Action: Notify the patient's provider of the results.
- Rationale: High glucose levels require a provider's intervention and fall outside normal reference
ranges.
