Which statement about scalpel blades and disposal is true?

• A. Scalpels may be one disposable piece or designed with a reusable handle and a disposable blade
• B. Scalpels blades must be stainless steel
• C. Scalpels do not have varying sizes or shapes
• D. A number on the blade distinguishes the scalpel's size and shape

Answer: (D)

Understanding scalpel blades hinges on recognizing that they come in different sizes and shapes, and those differences are identified by a number on the blade. That numeric code tells you the blade’s geometry—its size and shape—so you can choose the right blade for the procedure and handle disposal safely, since you know exactly which blade you’re using.

While scalpel assemblies can be sold as disposable units or as reusable handles with disposable blades, and blade materials can vary, the stable, universally true point is that the blade number denotes its size and shape. For example, different numbers correspond to blades designed for broad incisions, fine stab wounds, or precision work, guiding proper use and safe disposal.
