When performing venipuncture in an older adult, which technique helps reduce vessel trauma?

• A. Decrease the angle of insertion
• B. Increase the angle of insertion
• C. Use a larger gauge catheter
• D. Apply a tourniquet for a longer period

Answer: (A)

Fragile veins in older adults benefit from a shallow entry that minimizes how deeply the needle penetrates. Decreasing the angle of insertion keeps the needle tip more parallel to the vein, allowing a gentle entry that enters the lumen without digging through the posterior wall or causing excessive trauma. A steeper angle would drive the needle deeper and increase the risk of penetrating the vein or surrounding tissue. Using a larger gauge catheter would create a larger puncture, which raises trauma, and keeping a tourniquet on longer doesn’t specifically reduce vessel injury and can worsen vein swelling.
