NHA Certified Clinical Medical Assistant (CCMA)Clinical Patient CareMedium
A medical assistant is preparing to perform a venipuncture on a patient with visible petechiae on the arm. Which of the following actions should the medical assistant take?
- AChoose an alternate site for venipuncture.
- BUse a smaller gauge needle for the venipuncture.
- CProceed with the venipuncture as petechiae do not affect blood draw.
- DApply a warm compress to the area before venipuncture.
Show answer & explanationAnswer & explanation
Correct answer: A. Choose an alternate site for venipuncture.
Petechiae indicate fragile capillaries and a potential bleeding disorder, which can complicate venipuncture. Choosing an alternate site is the safest approach to prevent further bruising or complications.
Why the other options are wrong
- B. While a smaller gauge needle might cause less trauma, the underlying issue of capillary fragility remains, making an alternate site preferable.
- C. Petechiae indicate capillary fragility, which can affect the blood draw and lead to excessive bruising.
- D. Applying a warm compress might further increase capillary fragility or blood flow in an already compromised area.
Petechiae and Venipuncture
Petechiae are small, pinpoint hemorrhages under the skin. Their presence on an arm designated for venipuncture indicates capillary fragility or a potential bleeding disorder, requiring site re-evaluation.
- Indicates fragile capillaries.
- Suggests potential bleeding issues.
- Requires selection of an alternative venipuncture site.
