Two hand-tie: gives the best knot security Is rarely used in surgery rarely used in surgery Is not a useful knot Is faster than a one hand tie - Answer- Gives the best knot security Which of the following methods of suturing should be used to close a deep layer located on the medial edge of a myocutaneous flap closure of a sacral decubitus? Halstead suture with 0 Vicryl CTX simple running with 0 Vicryl SH Cushing suture with Prolene FS half-buried mattress suture with 0 PDO FS - Answer- half-buried mattress suture with 0 PDO FS Keloids are: broken bones enlarged scar due to formation of excessive amounts of collagen the end result of scarring type of skin flap - Answer- *enlarged scar due to formation of excessive amounts of collagen True or False: All of the following are correct tip for holding retractors 1. When holding a retractors only use the amount of force necessary for visualization 2. Focus on holding the retractor even if you are holding it for hours- lack of focus will cause the retractor to move and block visualization. 3. When holding a army-navy type retractor tow-in with the retractor-term refers to placing pressure on the end of the retractor keeping it slightly down while slightly lifting in/up-wards this motion will help keep a blunt from slipping out 4. when holding two retractors you will need to use counter and counter-traction to maintain proper visualization - Answer- True If during the course of an operation in which initially clean wound was made and the pharyngeal cavity was entered, the wound is now: still a clean wound a contaminated wound a clean, contaminated wound an infected wound - Answer- a clean, contaminated wound True or False: Lithotomy position is another modification of the supine position with the patient lying on their back with their legs in stirrups or on leg braces exposing the perineum, vagina, and rectum. Care must always be taken to prevent injury to the Obturator nerve. - Answer- True All of the following statements concerning Trendelenburg position are true Except Head of the bed tilted downward approximately 40 degrees. Knees are placed over the lower break in the bed which is lowered to help stabilize the patient. This position causes the abdominal viscera to move upward toward the diaphragm often results in decreased lung volume and compression of the heart. I can also cause increased intracranial pressure and hypertension and should not be used for extended periods of time Trendelenburg position can be used to treat a patient in hypovolemic shock. It raises blood pressure by reducing venous stasis in the legs and increasing the blood supply to the head and trunk. "Shock position" can include the entire bed being tilted downward toward the head or the trunk can be kept level and just the legs elevated. To prevent the patient from sliding toward the head of the bed and causing a shear injury or fall, well padded shoulder braces can be placed at the acromion processes Trendelenburg position is used for procedures of the head and neck - Answer- Trendelenburg position is used for procedures of the head and neck True or False: Primary intention or first intention wound healing: Refers to the healing process following closure of a clean surgical incision closed with suture material - Answer- True True or False: Granulation or Second intention wound healing the Wound is irrigated, nonviable tissue removed and wound is closed 4 to 7 days later - Answer- False Which of the following physical characteristics of sutures is described as the amount of force necessary to break the suture? knot strength memory elasticity tensile strength - Answer- tensile strength Factors which affect wound healing include: age steroids weight all the above - Answer- all the above True or False: Armboards can be positioned at various angles and must never be abducted greater than 90 degrees to avoid injury to the Axillary nerve plexus. - Answer- False Taper point needles are generally used in which of the following tissue types? 1. gastrointestinal 2. tendons 3. adipose 4. vascular 1, 2 and 3 1, 2 and 4 1, 3 and 4 2, 3 and 4 - Answer- 1, 3, and 4 True or False: Reverse Trendelenburg position is a modification of the supine position with the patient lying on their back with the entire bed tilted with head up and feet down. To prevent the patient from sliding downward, a padded foot board is used. Steep reverse can decrease venous return, since blood may pool in the lower extremities, sequential compression devices (SCD) or anti embolic stockings should be applied to the legs. - Answer- True Which of the following should be considered when positioning a patient? 1. Patency of the airway is the prime concern when positioning a patient. 2. Pressure injuries are most common after surgical procedures lasting one hour or longer. 3. An anesthetized patient with muscle paralysis is at increased risk for muscle strain. 4. The most common sites of peripheral nerve injury are the divisions of the brachial plexus and the ulnar, radial, perineal, and facial nerves. 1, 2, and 3 only 1, 2, and 4 only 1, 3, and 4 only 2, 3, and 4 only - Answer- 1, 2, and 4 only
