In a linear stapler, which statement is true?

• A. They use only one row of staples
• B. They place 2-3 rows of staples on either side of the knife blade
• C. They place no staples and rely on sutures
• D. They require a 20 mm port

Answer: (B)

In a linear stapler, tissue is captured and then stapled in multiple rows on either side of a central cutting blade. When deployed, two to three rows of staples are formed on each side of the knife, and the blade passes between them to transect the tissue. This configuration creates a secure, hemostatic seal along the cut line in a single action.

That’s why the statement is true: placing 2-3 rows of staples on each side of the knife blade is the defining feature of how a linear stapler closes and divides tissue. The other options don’t fit because one row wouldn’t provide adequate closure, relying on sutures defeats the stapler’s purpose, and the size of the port is not a defining characteristic of the stapler’s mechanism (devices come in various sizes, and a 20 mm port is not a standard requirement).
