ATI TEAS (Test of Essential Academic Skills) Version 7ReadingMedium
A medical assistant is preparing a patient for a blood draw. The patient asks, 'Why do I need to hold my arm still after you take the needle out?' Which of the following is the most appropriate response?
- AIt prevents bruising and hematoma formation.
- BIt helps the blood clot faster.
- CIt reduces pain at the injection site.
- DIt ensures the vein collapses properly.
Show answer & explanationAnswer & explanation
Correct answer: A. It prevents bruising and hematoma formation.
Holding pressure and keeping the arm still after a blood draw helps to compress the punctured vein and surrounding tissues, which is crucial for preventing blood from leaking out and forming a bruise (ecchymosis) or a larger collection of blood (hematoma).
Why the other options are wrong
- B. While pressure aids clotting, the primary purpose of holding still is to prevent blood leakage from the vessel.
- C. Though it might indirectly reduce some discomfort, pain reduction is not the primary reason for holding still; preventing bleeding is.
- D. Veins collapse naturally; holding still doesn't directly cause or ensure this process.
Post-Venipuncture Care
Actions taken immediately after a blood draw to promote hemostasis and prevent complications.
- Apply direct pressure to the site.
- Keep arm extended and still.
- Prevents bruising and hematoma formation.
Memory trick: After the NEEDLE, HOLD still to STOP the BLEED.
