When starting a peripheral intravenous line, what is the recommended technique?

• A. Start proximally near the elbow
• B. Start distally and move up the arm if infiltration or vein blow occurs
• C. Start in the scalp
• D. Start in the foot

Answer: (B)

Starting with the most distal usable vein in the upper extremity and then moving up toward more proximal sites is the preferred technique. This approach preserves proximal veins for future IV access and provides a practical path if the current site fails. Distal hand or forearm veins are typically easier to cannulate, and advancing proximally after an unsuccessful attempt or if infiltration occurs allows you to continue therapy with fewer punctures in different limbs. If infiltration or a vein blow happens, you can switch to a more proximal vein in the same arm rather than starting over on another limb, which helps minimize tissue damage and delays in therapy. Scalp access is generally reserved for infants, while starting in the foot is not favored in adults due to higher infection risk, discomfort, and longer catheter dwell times.
