T or F Surgical Principles Flashcards
T or F: Rat tooth forceps have large, interlocking teeth and are used to grasp skin and place sutures
True
T or F: Babcock and Doyen forceps are self retaining, while Adson and Brown Adson forceps are not
Babcock (without teeth, used on delicate tissues) and Doyen (long, gentle tips are used for holding bowel) are self retaining forceps, while Adson (thumb forceps with several fine teeth in a single row) and Brown-Adson (teeth on edges of tips) forces are not
T o F: Periosteal elevators ratchet to reduce bone fractures
False
Kern and Richards forceps rachet to manipulate bone fractures to reductionwhile periosteal elevators remove muscle from bone. Both are orthopedic instruments
T or F: Needle holders are used to give intramuscular injections
False
Needle holders are used to hold suture needles and assist with tying sutures
T or F: Kelly forceps have distal transverse grooves, Crile forceps have complete transverse grooves, and Rochester-Carmalt forceps have both longitudinal and complete transverse grooves
True
T or F: Balfour and Gelpi are OVH (spay) hooks
False
Snook and covault are OVH hooks
T or F: The most common scalpel handle and blade combination is a #10 handle and #3 blade
False
Most common scalpel handle is #3 and the basic blade is #10
T or F: Metzenbaum scissors have one blade that is flat with a thich edge and blunted tip to cut bandage material from the underside
False
Yankauer suction tips remove abdominal fluid and are unable to be plugged by the omentum
False
Yankauer suction tips remove fluids other than blood. Poole tips remove abdominal fluid and are unable to be plugged by the omentum.
T or F: Edges of a wound must be dry before using a cyanoacrylate tissue adhesive
True
Tissue glue must be applied to dry edges that must be held together for about 15 seconds after application
T or F: In some cases, a skin stapler can be used to close a wound
True
T or F: A suture needle with an eye and threaded suture material is less traumatic than a swaged needle
False
When suture material is swaged onto the suture needle, the suture is less traumatic. When there is an eye, the suture needle is more traumatic to tissues
T or F: Chromic gut suture maintains its tensile strength longer than silk suture
False
Chromic gut suture is natural and absorbable, silk is natural and non-absorbable
T or F: A simple interrupted suture pattern is when each individual suture is placed separately with its own knot so failure of one suture does not result in failure of the entire line
True
T or F: Tap water is preferable when manually cleaning medical and surgical instruments
False
Recommended to clean instruments with distilled water when possible
T or F: Sterilized packs that are double wrapped with muslin have a longer shelf life than those double wrapped with a non-woven barrier such as paper
False
Non-woven material such as paper has a longer shelf life than woven material like muslin. Double wrapped packs have a longer shelf life than singe wrapped packs.
T or F: Basic cleaning of surgical instruments occurs in this order: presoaking –> decontaminating –> ultrasonic cleaning
True
T or F: Manual cleaning, ultrasonic cleaning, and the use of washer disinfectors are all ways to sterilize surgical instruments
False
Once they are thoroughly cleaned/disinfected then they go through sterilization
T or F: When cleaning instruments the box locks should be closed and locked to take up less space in the cleaning area
False
T or F: If you suspect a sterile item has touched a non-sterile item, everything should be considered unsterile and replaced
True
T or F: When opening sterile packages, ensure the sterility of the contents by opening the package away from you and not reaching over the sterile field
True
T or F: Isopropyl alcohol is the ideal surgical scrub to prepare an incision site for surgery
False
T or F: Open-gloving is when an individual puts on sterile gloves over the cuffs of a sterile gown
False
T or F: Orchidectomy is the surgical removal of the uterus; ovariohysterectomy is the surgical removal of the testicles
False
T or F: A laparotomy is performed for multiple reasons, including feline castration
False
T or F: Reduced appetite, a hematoma, and a lowered heart rate are all normal post-operative signs
False
Signs of post-operative infection include swelling, redness, heat and pain
True
T or F: A disinfectant that is labelled as virucidal kills viruses
True
“cidal” = killed
T or F: Medical items that come into contact with internal fluids through blood vessel walls (like IV catheters) must be sterile
True
T or F: Disinfectants that are bacteriostatic will kill bacteria
False
“static” = growth will be inhibited
T or F: When performing steam sterilization, as many packs should be loaded into the autoclave as possible to improve efficiency
False
T or F: An antiseptic is an antimicrobial agent kills or inhibits the growth of microorganisms on external surfaces of the body
True
T or F: The external indicator tape indicates that the pack has been exposed to the sterilization process and ensures that the instruments inside the pack as safe to use
False
T or F: Gravity displacement and high vacuum are two methods of sterilization that rely on ionizing radiation
False
They rely on moist heat (steam) at a certain pressure
T or F: Sterilization is the elimination or destruction of all living organisms excluding viruses and spores
False
T or F: Gas sterilization with ethylene oxide is an appropriate method of sterilization for heat sensitive items that cannot be sterilized with steam, like rubber and plastic
True
T or F: The disadvantage of biological indicators over chemical indicators when determining if sterilization was effective is that biological indicators do not provide an immediate answer and chemical indiators do
True
T or F: It is not necessary to clean surfaces prior to disinfecting
False
T or F: bacteria and bacterial spores can be killed by most commercial disinfectants
False
T or F: An antiseptic is an antimicrobial agent that kills or inhibits the growth of microorganisms on external surfaces of the body
True
T or F: Gravity displacement and high vacuum are two methods of sterilization that rely on ionizing radiation
False
T or F: Medical items that come in contact with internal fluids through blood vessel walls (like IV catheters) must be sterile
True
T or F: Bacteria and bacterial spores can be killed by most commercial disinfectants
