Which instrument is shaped like a duck's mouth and is attachable?

• A. Vaginal Speculum
• B. Nasal Speculum
• C. Webster Needle Holder
• D. Crile-Wood Needle Holder

Answer: (A)

The instrument described by a duckbill shape that can be attached is a vaginal speculum. Its two blades come together to form a beak-like opening, and it is designed to be inserted closed and then opened to hold the vaginal walls apart for visualization. Many specula are made to attach to a handle or have a mechanism to maintain the opening, which is what “attachable” refers to here. The other tools don’t fit this description: a nasal speculum is used for the nasal passages and isn’t characteristically described as a duckbill in the same way, and needle holders are long, scissor-like devices used to grasp suturing needles, not beak-shaped or attachable in the sense described.
