| Question | Answer |
|---|---|
| When using electrocautery, if good contact is maintained between the surgical patient's skin and the ground plate | The patient might be burned |
| Synthetic absorbable sutures offer an advantage over natural absorbable sutures because | They are not significantly affected by inflammation |
| When performing a laparoscopic procedure, the abdomen must be filled with gas to cause distention. This process is called | Insufflation |
| Multifilament suture has several strands. It has less tissue drag and no interstitial spaces to harbor bacteria | False |
| Like the CO2 laser, the diode laser also functions to ablate, incise, and excise soft tissue by way of photothermal laser-tissue interaction | True |
| Catgut is a suture constructed from the intestines of sheep, goats or cattle and consists mostly of collagen | Multifilament |
| Electrocautery is equivalent electrocoagulation | False |
| In a room with volatile anesthetic agents and compressed gas cylinders the risk of fire is a minimal concern. Surgical drapes, animal hair, alcohol used on the patients are rarely fire hazards | False |
| Filtering face masks specifically made for lasering should be worn in lieu of conventional surgical masks, because | They protect against the plume (smoke) |
| sutures are considered easier to pass through the tissues because they cause less resistance | Monofilament |
| Photothermal Ablation: laser is applied to soft tissue and the light energy is absorbed by the water existing in the soft tissue; by heating up and vaporizing the water | True |
| Lasers are divided into four classes according to their ability to | Inflict damage to skin or eyes |
| When using an arthroscope, it is important to keep in mind that to keep in mind that fiberoptic cables are easily damaged if | They are kinked excessively |
| needles have three cutting edges, however, the third edge is on the outer convex curvature of the needle and are designed to resist tissue cutout | Reverse - cutting |
| Why would skin staples be chosen over suture to close incision | They are all advantages over suture |
| Monopolar electrocautery is most efficient in a surgical site | Dry |
| ASA classification is rating of the anesthetic risk of the patient | True |
| The quarter drape is positioned a few centimeters from the proposed incision and once placed | Should never be advanced toward the proposed incision |
| lasers create minimal latent and collateral thermal damage and can be used for precise cutting | CO2 |
| patterns allow increased control of suture tension and apposition of wounds | Interrupted |
| Catgut is made from what organic material | Sheep |
| Preemptive analgesia makes IV catheterization less stressful for patient and staff, reduces the amount of induction agent, eases transition of anesthesia resulting in smoother recovery, avoids the wind up, and will often include an opioid/narcotic with a | True |
| Which of the following properties are the ideal properties of suture | Nonallergenic, Noncarcinogenic, Noncapillary, Absorbed with minimal reaction after tissue healed |
| The CO2 laser can be used with or without a smoke plume evacuator | False |
| sutures lose most of their breaking strength within 60 days of placement | Absorbable |
| What are two organic, non-absorbable suture materials | Silk Cotton |
| It takes 45-60 seconds for tissue adhesive to set | False |
| Choose all questions you should ask an owner checking in their animal for surgery | Are you the owner or do you have authorization to make treatment decisions for the pet? Have they been fasted properly? Abnormal bleeding or bruising? Travel history? Previous or ongoing illness, if so, what treatment was pursued? Allergies or drug r |
| A patient undergoing an intercoastal thoracotomy should be positioned for surgery in | Lateral recumbency |
| Surgical gloves should be wet when abdominal organs are touched, particularly the gastrointestinal tract, because dry gloves can | Cause tearing of the serosal layer or drying of the organs |
| You should place IV catheters in anesthetic patients because it is recommended to readily have access available to a vein in case you should need to administer fluids or medications during surgery | True |
| When preparing to introduce an arthroscope into a joint, a sharp trocar is inserted into a hollow, cannula-type instrument called the . Both the trocar and this instrument are then used to penetrate the fibrous portion of the joint cap | Arthroscope sleeve |
| All personnel in the laser OR should wear eye protection goggles made for every possible type wavelength of laser light | False |
| Suture needles can be preloaded with suture. This is called a/an needle | Swaged |
| Different types of surgical laser units get their energized light from any of the following sources except | Liquid nitrogen |
| Electrocautery plates | Should be in direct contact with the patient at all times |
| As suture diameter decreases, tensile strength increases | False |
| is an example of a braided multifilament suture | Polyglycolic acid (Dexon) |
| What is one advantage of stainless-steel suture | Stable in contaminated wounds |
| Which of the following properties are the ideal properties of suture? Select the choices that are correct for credit. There may be more than one | Absorbed with minimal reaction after tissue healed Noncapillary Noncarcinogenic Nonallergenic |
| sutures have greater capillary action | Braided |
