A patient arrives at the provider's office with a laceration on their right forearm, and the provider determines the patient will need sutures. Which of the following supplies should the medical assistant hand to the provider?

The appropriate supply to hand to the provider in this scenario is the needle holder with the suture already attached. This option is correct because when suturing a laceration, the provider needs a needle holder to properly grasp and manipulate the needle and suture material during the procedure. The needle holder is designed specifically for suturing, providing the necessary control and precision to stitch the wound effectively.

Handing the needle holder with the suture already attached streamlines the process for the provider, allowing for efficiency and reducing the time the wound is open. Additionally, it ensures that the provider has immediate access to the suture, which is essential for wound closure and facilitating healing.

While the antiseptic solution, local anesthetic, and scalpel are all relevant supplies in a surgical setting, they serve different purposes. The antiseptic solution is necessary for cleaning the area to prevent infection, the local anesthetic is used to numb the area before suturing, and the scalpel is typically used for initial incision or debridement, not specifically for the suturing process. Thus, while those items are important, they are not as directly tied to the immediate action of suturing as the needle holder with the suture.
