Which statement about interrupted sutures is true?

• A. Interrupted sutures are less cumbersome but each requires a knot
• B. Interrupted sutures require constant tension
• C. Interrupted sutures allow continuous tension
• D. Interrupted sutures never require knots

Answer: (A)

Interrupted sutures place and secure each stitch individually, with its own knot. This arrangement gives precise control of how each bite brings tissue edges together and makes it easy to modify or remove a single stitch without disturbing the rest. That’s why the statement that interrupted sutures are less cumbersome while each requires a knot is the best fit: you gain local control and straightforward adjustment, but you still have a knot for every stitch. The other ideas don’t fit the pattern of interrupted sutures. You don’t rely on a single constant tension across all stitches, since tension is set per stitch and can be adjusted as tissue conditions change. A running, continuous suture provides a way to distribute tension along a length, which isn’t how interrupted sutures function. And obviously, each interrupted stitch needs a knot, so the notion that they never require knots isn’t correct.
