Question 1

A virucidal disinfectant:

Accepted Answer

A virucidal disinfectant is specifically designed to kill viruses. It may or may not be effective against bacteria, but its primary purpose is to eliminate viruses. Options A and C may be true for other types of disinfectants, but not for virucidal disinfectants. Option D is not a correct choice for the same reason as option C.

Question 2

For steam and gas sterilization, instruments should be organized:

Accepted Answer

Instruments should be placed on a lint-free towel on the bottom of a perforated metal instrument tray for proper sterilization. This allows for proper circulation of the sterilizing agents around all surfaces of the instrument. Choices A, C, and D are not necessary for organizing instruments for sterilization.

Question 3

Hemostasis means :

Accepted Answer

Hemostasis refers to the arrest or cessation of bleeding. It is the goal of surgical or medical procedures to achieve hemostasis to prevent excessive blood loss. Options A and D are incorrect as they refer to uncontrolled bleeding and blotting blood away from the surgical site respectively. Option B is not entirely correct as minimal bleeding may still occur, and the goal is to achieve complete hemostasis.

Question 4

An incision into the intestine is called:

Accepted Answer

An incision into the intestine is called an enterotomy. Gastrotomy refers to an incision into the stomach, intestinal resection and anastomosis involves the removal of a segment of the intestine and the joining of the remaining ends, and laparotomy refers to a surgical incision into the abdominal cavity.

Question 5

Which serrations on hemostatic forceps are gentler on tissue?

Accepted Answer

Longitudinal serrations are gentler on tissue because they have a longer length and a shallower depth compared to other types of serrations. This results in less trauma to the tissue being manipulated.

Question 6

Metzenbaum scissors should be reserved for:

Accepted Answer

Metzenbaum scissors are designed for delicate or fine tissue dissection. They have a narrow blade, a sharp tip, and a longer handle to provide greater precision and control. They should not be used for heavier tissues such as fascia or for cutting through suture material. Using Metzenbaum scissors for heavier tissues can cause the blades to become damaged or dulled. Therefore, choice A is the best choice.

Question 7

Before gas sterilization, items should be:

Accepted Answer

Before gas sterilization, items must be clean and dry to ensure that no dirt or moisture can inhibit the effectiveness of the sterilization process. Aeration or autoclaving are not necessary before gas sterilization, and rinsing with sterile water may not be sufficient to remove all contaminants.

Question 8

The following are examples of needle shapes, except:

Accepted Answer

All of the other choices (tapercut, spatula point, regular cutting) are types of needle shapes commonly used in medical procedures, while "swagged" is not a needle shape.

Question 9

Which of the following instruments is appropriate for holding tissues during surgery?

Accepted Answer

Brown-Adson forceps are specifically designed for holding delicate tissues during surgeries. Angiotribes are used for clamping vessels, standard surgical scissors are used for cutting tissues, and sponge forceps are used for holding sponges.

Question 10

With the needle and suture joined as a continuous unit in swaged needles:

Accepted Answer

With the needle and suture joined as a continuous unit in swaged needles, ease of use is increased as there is no need to thread the suture through the eye of the needle. This also minimizes tissue trauma as there is no additional manipulation of the suture through the tissue.

Question 11

The term virulence means :

Accepted Answer

The term virulence refers to a microorganism's ability to cause disease, specifically the degree or intensity of the disease that the microorganism is capable of causing. The other options - resistance of a bacteria to an antibiotic, enough microorganisms to overcome a patient's defenses, and resistance of a patient to infection - do not directly relate to virulence.

Question 12

Before putting soiled instruments into an ultrasonic cleaner:

Accepted Answer

Soiled instruments should be washed in cleaning solution before being placed in the ultrasonic cleaner to remove debris and organic material. It is important to remove as much debris as possible before placing instruments in the ultrasonic cleaner to ensure that the cleaning process is effective.

Question 13

Standard practice is to withhold food from healthy dogs scheduled for surgery for ___ hours prior to anesthetic induction.

Accepted Answer

The standard practice is to withhold food for 8-12 hours prior to surgery to prevent vomiting and regurgitation during anesthesia, which can lead to aspiration pneumonia. However, it is important to consult with the veterinarian as individual patients may have different requirements based on their overall health condition and the specific procedure they are undergoing.

Question 14

The surgical procedure in which calculi are removed from the urinary bladder is called:

Accepted Answer

Cystotomy is the surgical procedure in which calculi are removed from the urinary bladder. A cystostomy is a surgical procedure in which an opening is made in the bladder to drain urine, urethrostomy is the surgical creation of a new urethral opening, and calculectomy is not a commonly used term in veterinary medicine.

Question 15

Gravity displacement autoclaves:

Accepted Answer

Gravity displacement autoclaves involve water that is heated in a chamber to create steam, which then displaces the air out of the chamber through a vent. This type of autoclave does not use a boiler or vacuum pump. While gravity displacement autoclaves are commonly used in veterinary medicine, they are also used in other industries for sterilization purposes.

Question 16

Which physical method of sterilization is commonly used in veterinary hospitals?

Accepted Answer

Moist heat is the most commonly used physical method of sterilization in veterinary hospitals as it is fast, efficient, and does not damage most materials. The use of autoclaves, which use moist heat under pressure, is a common practice in veterinary hospitals. Radiation and filtration are not commonly used for sterilization purposes in veterinary hospitals. While dry heat can also be effective, it requires longer exposure time and higher temperatures which can damage some materials.

Question 17

Multifilament suture:

Accepted Answer

Multifilament sutures are more pliable and flexible than monofilament sutures, which makes them easier to handle and tie. This is due to their structure, consisting of several filaments twisted or braided together.

Question 18

Which instrument is typically used to retract the abdominal wall?

Accepted Answer

The Balfour retractor is specifically designed for retracting the abdominal wall during surgical procedures. The other instruments listed may be used for retracting other tissues, such as bone or skin.

Question 19

The definition of sterile is:

Accepted Answer

The definition of sterile includes being without pathogenic microbes, bacteria, viruses, or spores. Therefore, both option B (without bacteria) and option C (without viruses or spores) are included in the definition of sterile.

Question 20
