NWCA Phlebotomy Technician Credential Practice Exam

What should you do if you cannot feel a vein after palpation?

Reassess the patient, consider warming the arm, or choose an alternate site; do not force a draw Apply more pressure to palpate Use a tourniquet tighter Ask patient to move a finger

Correct Answer:

Reassess the patient, consider warming the arm, or choose an alternate site; do not force a draw

Explanation:

When a vein isn’t felt after palpation, the move is to pause and reassess rather than forcing a draw. Start by warming the arm to promote vasodilation, orient the arm so the hand is lower than the heart to aid venous filling, and consider selecting a different venipuncture site if a suitable vein remains elusive. Forcing a draw by pressing harder, tightening the tourniquet, or waiting for finger movement to reveal a vein can injure tissue, cause pain, and lead to a failed collection or hematoma. If a vein still cannot be found after these steps, stop and try again later or switch to an alternative site with proper consent and communication to the patient.
