- AAttempt to find a vein within the tattooed area if it appears healthy.

- DRefer the patient to a more experienced phlebotomist.
Show answer & explanationAnswer & explanation
Correct answer: B. Select a vein in the dorsal side of the hand or wrist.
Tattooed skin can obscure veins, mask signs of infection, and potentially increase the risk of infection or reaction. While some sources say it's acceptable if the skin is healthy and veins are visible, the safest practice is to select an alternative site without tattoos, such as the dorsal hand or wrist, if available.
Why the other options are wrong
- A. Drawing through tattooed skin is generally discouraged due to potential complications and difficulty in site assessment.
- C. While asking about past experiences is part of good communication, it doesn't override the safety principle of avoiding tattooed areas if possible.
- D. Referring to another phlebotomist isn't the first step; the technician should attempt to find an appropriate alternative site first.
Venipuncture in Tattooed Areas
Drawing blood from skin covered by tattoos.
- Generally avoided due to obscured veins, infection risk, and skin reactions.
- Alternative sites (e.g., dorsal hand) are preferred.
- If unavoidable, select an area of healthy, intact skin.
Memory trick: Tattoos are art, but for draws, pick a clean part!
