A medical assistant is preparing to perform a venipuncture on a patient with visible petechiae. Which of the following actions should the medical assistant take?
- AUse a smaller gauge needle to minimize additional trauma.
- BSelect an alternative site for venipuncture or notify the provider.
- CProceed with the venipuncture as usual, as petechiae are harmless.
- DApply a warm compress to the site before venipuncture to improve blood flow.
Show answer & explanationAnswer & explanation
Correct answer: B. Select an alternative site for venipuncture or notify the provider.
Petechiae indicate capillary fragility or a bleeding disorder, increasing the risk of excessive bleeding or hematoma formation during venipuncture. It is safest to select an alternative site without petechiae or consult the provider for guidance.
Why the other options are wrong
- A. While a smaller needle might cause less trauma, the underlying issue of capillary fragility remains, making the site risky.
- C. Petechiae indicate capillary fragility, so proceeding as usual increases bleeding risk.
- D. A warm compress would further dilate capillaries and could exacerbate bleeding in a patient with petechiae.
Petechiae and Venipuncture
Petechiae are small, pinpoint hemorrhages under the skin, indicating capillary fragility or bleeding tendencies, which can complicate venipuncture.
- Indicate capillary fragility.
- Increased risk of hematoma or bleeding.
- Requires careful site selection or provider consultation.
Memory trick: When petechiae appear, caution is clear, find a new vein, or call the provider, dear.
