SURGICAL INSTRUMENTS QUIZ

**1. What is the primary purpose of a scalpel?**

- **Answer:** To make precise incisions in skin and tissue.

- **Rationale:** Scalpels have sharp, removable or fixed blades

designed for cutting with minimal trauma.

**2. Which instrument is used to grasp and hold tissue or needles?**

- **Answer:** Needle holder (e.g., Halsey, Mayo-Hegar).

- **Rationale:** Needle holders have short jaws with a cross-hatched

surface to securely grip a suture needle without damaging it.

**3. What is the forked instrument used for grasping tissue like tonsils

or adenoids?**

- **Answer:** Allis forceps.

- **Rationale:** Allis forceps have teeth that interlock, providing a firm

grasp on dense tissue but can be traumatic.

**4. Which instrument is used to clamp blood vessels or absorbable

tissue before ligation?**

- **Answer:** Hemostat (mosquito or Kelly clamp).

- **Rationale:** Hemostats have serrated jaws and ratchets to occlude

5. What distinguishes a Kelly clamp from a mosquito clamp?

Answer: Kelly clamps have serrations along the entire jaw, while mosquitoes have fine, full-length serrations and are smaller.
Rationale: Kellys are for slightly larger vessels; mosquitoes for delicate, fine vessels. 6. Name the instrument used to separate tissue layers by spreading without cutting.
Answer: Metzenbaum scissors or Mayo dissecting scissors.
Rationale: Blunt dissection spreads tissue along natural planes, minimizing bleeding. 7. Which scissors are best for cutting delicate tissue like mesentery?
