Chapter 21. Robotic Surgery MULTIPLE CHOICE 1. A suture is a suture-needle combination designed to release the suture easily. A. double-armed C. swaged suture-needle combination B. spring-eye needle D. control-release ANS: D A detachable suture is one in which the suture detaches from the needle by pulling it straight back from the swage. These are referred to by their proprietary names such as de-tach or control-release. PTS: 1 DIF: 2 REF: p. 457 2. dressings are used to prevent or limit movement of the surgical wound during healing. A. Flat C. Supportive B. Pressure D. None of the above ANS: C Supportive dressings are used to prevent or limit movement of the surgical wound during healing. Thick cotton covered with stretch gauze is used for soft support. Hard casting materials are used when complete immobility is required. PTS: 1 DIF: 2 REF: p. 471 3. The needle has a round body that narrows to a sharp point. It punctures tissue, making an opening for the body of the needle to follow. Its primary use is for suturing soft tissue. A. blunt C. cutting B. tapered D. spatula ANS: B The tapered needle has a round body that tapers to a sharp point. It punctures tissue, making an opening for the body of the needle to follow. Its primary use is for suturing soft tissue such as muscle, subcutaneous fat, peritoneum, and dura, as well as gastrointestinal, genitourinary, biliary, and vascular tissue. PTS: 1 DIF: 2 REF: p. 458 4. The process of suturing two tissue edges together is called . A. approximation C. stitching B. ligation D. locking ANS: A The primary use of sutures is to repair or construct tissue. The process of suturing other means to hold two tissue edges together is called approximation. Suture is also used to tie or ligate bleeding vessels. PTS: 1 DIF: 2 REF: p. 459 5. Mucous membrane or organ tissue such as spleen tissue requires forceps. A. toothed C. Adson B. smooth or vascular D. Russian ANS: B Smooth forceps are used on mucous membrane organ tissue such as spleen and kidney and any tissue that bleeds easily. PTS: 1 DIF: 2 REF: p. 464 6. A(n) suture is a continuous suture used to approximate the open ends of a lumen. It is traditionally used during an appendectomy to close the base of the appendix after the distal portion is removed. A. interrupted C. mattress B. running D. purse-string ANS: D The purse string is a special continuous suture technique for closing the end of a tubular structure (lumen) such as the appendix, which is its most common application. In this technique, one end of the suture is anchored and stitches are placed around the periphery of the open “tube.” PTS: 1 DIF: 2 REF: p. 461 7. In areas where great strength is required, such as abdominal incisions, sutures are used in conjunction with routine abdominal suture layers to add support to the closure. A. retention C. horizontal mattress B. continuous D. vertical mattress ANS: A Retention sutures are a type of interrupted technique used to provide additional support to wound edges in abdominal surgery. In this technique, heavy sutures are placed though all the tissue layers of the body wall several centimeters from the primary suture line. PTS: 1 DIF: 2 REF: p. 462 8. When cutting sutures, use only scissors. To cut the suture, open the scissors slightly. Use only the tips of the scissors to cut; never the midportion of the blades. Cut only when you can see what you are cutting. A. tissue C. sharp suture B. bandage D. Potts ANS: C The proper technique for cutting sutures is as follows: • Use only sharp suture scissors; never use tissue scissors on suture material. • To cut the suture, open the scissors slightly. Use the tip of the scissors to cut, because this provides more control. • Place your index finger over the top of the scissors to steady the blades. Turn the scissors at a 45- degree angle. This creates a small “whisker.” Cut the suture ends while keeping the scissors at an angle. • When cutting sutures and performing other tasks at the same time, “palm” the scissors in one hand. • Remove any cut suture ends from the wound area to prevent them from falling into the wound. PTS: 1 DIF: 2 REF: pp. 465-466 9. are small V-shaped staples that close down and occlude a vessel or duct.
