PERIOPERATIVE QUIZ 100% SOLVED 2024 CHAPTER 7 - Answer- NEEDLES, SUTURES, INSTRUMENTS List examples of nonabsorbable sutures. Silk, nylon, polyester fiber, polypropylene, and stainless steel wire are examples of nonabsorbable sutures. - Answer- List the indications for using a surgical adhesive. Surgical adhesives are used in place of subcuticular sutures 4-0 in diameter or less in areas that are not under high tension or subject to increasing tension with movement Define the term suture Suture is a generic term for all materials used to sew severed body tissues together and to hold these tissues in their normal position until healing takes place; to suture is to stitch together cut or torn edges of tissue - Answer- List examples of instruments or other devices used for blunt dissection. Blunt dissectors include gauze dissectors (e.g., peanuts, pushers, kitners), a sponge on a stick, the back of a knife handle, and the surgeon's finger or hand. Define the term ligature A ligature is a strand of suture material used to tie off (seal) blood vessels for the prevention of minor bleeding, or to isolate a mass of tissue for excision (cut out) - Answer- Describe the ideal suture. An ideal suture causes minimal inflammation and tissue reaction while providing maximal strength during the lag phase of wound healing. Describe the "no touch" sharps technique Sharps are placed in a predesignated basin, tray collection device, or safe ''neutral'' zone on the field, from which the surgeon can retrieve the sharps. After use, the item is placed back in the neutral zone, and the scrub person retrieves it - Answer- Define the secondary suture line. The secondary suture line is composed of those sutures that supplement the primary suture line. Define the term retention suture Retention sutures are placed at a distance from the primary suture line to provide a secondary suture line, relieve undue strain, and help obliterate dead space - Answer- List the different types of endomechanical staplers used for internal stapling. Ligating and dividing staplers (LDSs), gastrointestinal anastomosis (GIA) staplers, thoracoabdominal (TA) staplers, end-to-end anastomosis (EEA) staplers, laparoscopic hernia mesh staplers, open hernia mesh staplers, and endo-GIA devices are used internally What is the function of the barbs in barbed suture? The barbs help the tissue to stay approximated with equal wound tension and eliminate the need to tie knots. - Answer- Describe the purpose of surgical soft goods. Surgical sponges are used to affect hemostasis via direct pressure, absorb intraoperative blood loss and drainage, aid in blunt dissection, pack viscera from the field, and keep areas of the wound moist Describe how sutures are measured. Suture size is measured in millimeters, and expressed in USP sizes with zeroes. The smaller the cross-sectional diameter, the more zeroes; sizes range from #7, the largest, to 11-0, the smallest - Answer- Describe when surgical counts (e.g., sponge, sharp, instrument) are performed. Counts are performed initially, before the patient enters the operating room (OR), before closure of a body cavity or deep, large incision; after closure of a body cavity; and at skin closure Define the term subcuticular suture. Subcuticular sutures are placed completely under the epidermal layer of the skin. This technique is often used for cosmetic closure. - Answer- Define tensile strength. Tensile strength is the amount of weight (breaking load) necessary to break a suture (breaking strength); it varies according to the type of suture material. Describe the techniques used to ligate in deep tissues. The following techniques can be used to ligate in deep tissue: (1) A hemostat is placed on the end of the structure; the ligature is then placed around the vessel. The knot is tied and tightened with the surgeon's fingers or with the aid of forceps. (2) A slipknot is made, and its loop is placed over the involved structure by means of a forceps or clamp. (3) In deeper cavities, ties are often placed on clamps with the long end extending from the tip. These are sometimes called ties on a pass or bow ties. The extending long end is held tightly against the rings by the surgeon (creating the bow), who then passes the tip of the clamp under the vessel or duct to be ligated. The first ass
