Certified Surgical Technologist (CST) Practice Exam

When placing a swaged needle onto a needle holder, the needle should be clamped:

1. One-third distance from the needle point

2. Three-fourths distance from the needle point

3. At the junction of suture and needle

4. Half-way distance from the needle point

The correct answer is: Three-fourths distance from the needle point

When placing a swaged needle onto a needle holder, clamping the needle at a distance of three-fourths from the needle point is considered optimal for a few key reasons. This positioning provides the surgeon with better control over the needle during suturing, allowing for precise maneuvers, especially in tight or constrained anatomical spaces. Clamping farther from the needle point supports leveraging the natural curve of the needle, which helps in directing it through tissues more effectively. It minimizes the risk of the needle bending or breaking, which can occur if it is clamped too close to the point or at an improper angle. Additionally, this technique ensures adequate distance for the suture to be pulled through without causing excessive tension or damaging the tissue. Positioning the clamp at this recommended distance aligns with best practices in surgical technique, ensuring both the safety and efficacy of the suturing process. This understanding of needle placement enhances the surgical technologist's role in maintaining optimal conditions during a procedure.
