NEW QUESTION # 131
What benefit does an edge artifact provide when performing an ultrasound?
Answer: C
Explanation:
An edge artifact is created by refraction leading to a hypoechoic band at the edge of a curved structure secondary to the redirection of the sound beam. It helps identify round, smooth structures such as the bladder and cystic structures.
Acoustic enhancement occurs as the beam of the ultrasound passes through a structure, like the gallbladder, that is fluid-filled. It has a low sound attenuation compared to the liver and, thus, slows the sound down. The echo that returns to the transducer is of higher intensity, causing an increased echogenicity. It creates an artifact deep to the fluid-filled structure.
Acoustic shadowing is an artifact that occurs when insufficient sound penetrates a sound-absorptive substance. It produces a dark or less echogenic area than the nearby tissue. It occurs deep to dense material like calcium or bone. Basically, most of the beam is absorbed or reflected and occurs at bone, gas, foreign body, or fecal interfaces.
Finally, evenly spaced parallel lines, or comet tails, represent reverberation artifacts. These form as the ultrasound beam reaches air or other gas. This causes the entire beam to reflect back on the transducer while some will then re-enter the patient. This then continues in a cycle, and the sound keeps bouncing from the patient to the gas to the patient. It creates two bright parallel lines representing the distance between the transducer and the gas interface. We commonly see this in the GI tract or with metal objects. So, they may be beneficial in identifying metal objects or other foreign material, including a biopsy needle.
NEW QUESTION # 132
Which regulatory agency controls the development, testing, and approval of topical medications used in parasite prevention?
Answer: A
Explanation:
Topical parasiticides are regulated by the United States Environmental Protection Agency (EPA). Topical parasiticides include amitraz, imidacloprid, fipronil, and permethrin. In addition to pesticides, the EPA Pesticide Regulation Division regulates insecticides and rodenticides.
The Food and Drug Administration (FDA) regulates veterinary drugs and devices, pet foods, livestock feeds, prescription and non-prescription drugs, vaccines, and blood products. The United States Department of Agriculture (USDA) oversees the area of veterinary medicine that aims to prevent, treat, or diagnose animal diseases. The United States Pharmacopoeia (USP) compiles a list of all drugs into one place.
NEW QUESTION # 133
When describing relative echogenicity between two structures, isoechoic refers to which of the following statements?
Answer: C
Explanation:
Echogenicity describes the gray scale appearance of different tissues and structures. It is useful in interpreting normal vs. abnormal tissue appearance.
Isoechoic structures that have the same echogenicity (brightness) as surrounding tissues Hyperechoic structures are brighter than surrounding tissues Hypoechoic structures are darker than surrounding tissues Anechoic structures appear black and do not produce echoes Joanna M. Bassert, VMD. McCurnin's Clinical Textbook for Veterinary Technicians, 9th Edition. Pg 512.
Mosby's Comprehensive Review for Veterinary Technicians 5th Edition. Pg 176.
NEW QUESTION # 134
Which term refers to the portion of the tooth closest to the inside of the cheek?
Answer: C
Explanation:
Buccal refers to the portion of the tooth closest to the inside of the cheek.
Palatal is the portion of the tooth closest to the palate and is typically used for maxillary teeth. Lingual is the portion of the tooth closest to the tongue and is typically used for mandibular teeth. Apical (towards the apex) is the portion of the tooth closest to the root.
NEW QUESTION # 135
Properly draping a patient at the start of surgery ensures the patient and surgical field remain sterile. The veterinarian will be performing an abdominal exploratory.
Of the following equipment, what will you not need to drape the patient?
Answer: A
Explanation:
The equipment needed to use the quarter drape technique includes 4 quarter drapes, appropriately sterilized towel clamps, such as Backhaus clamps, and a large surgical drape. When draping the body using this technique, they create a window where the incision will be made, and they are then secured by the clamps. The veterinarian will then take a large surgical drape and make a fenestration to provide access to the surgical field, thereby covering the clamps, so they are not in the way.
A stockinette may be needed, but it is not equipment used in draping. However, we know that this is abdominal surgery, not a limb surgery or a surgery where the limb may be in the way and would need to be manipulated during surgery (which is where a stockinette would be used). Knowing what surgery will be performed helps you anticipate what will be required and the type of services you may provide either as a sterile or non-sterile surgery technician.
