A patient's arm shows signs of a hematoma forming during venipuncture. What is the FIRST action to take?
Answer: Apply pressure and remove the needle immediately
When a hematoma forms, the needle should be removed immediately and firm pressure applied to prevent further blood leakage into surrounding tissue.
Which evacuated tube color is used for serum chemistry tests requiring no additive?
Answer: Red
Red-top tubes contain no additive and allow blood to clot naturally, producing serum for chemistry testing.
What is the recommended angle of needle insertion for a standard venipuncture?
Answer: 15–30 degrees
A 15–30 degree angle is recommended for venipuncture to enter the vein cleanly without passing through it.
Which condition requires the phlebotomist to draw blood from the hand or wrist rather than the antecubital fossa?
Answer: Mastectomy on the ipsilateral side
Drawing from the arm on the same side as a mastectomy is contraindicated due to lymphedema risk, so alternate sites such as the hand are used.
A phlebotomist notices the tube is not filling during an ETS draw. Which is the LEAST likely cause?
Answer: Patient's blood pressure is too high
High blood pressure would not prevent tube filling; it is more commonly associated with rapid, forceful filling rather than failure to fill.
When performing a capillary puncture on an infant, which site is preferred?
Answer: Medial or lateral plantar heel
The medial or lateral plantar surface of the heel is the recommended site for infant capillary puncture to avoid bone and nerve damage.
Which tube additive prevents glycolysis and is used for glucose testing?
Answer: Sodium fluoride
Sodium fluoride inhibits glycolysis, preserving glucose levels in the specimen until it can be tested.
