NEW QUESTION # 327
With Cushing's disease, which of the following substances will be elevated in the blood?
Answer: A
Explanation:
Cushing's syndrome, or hyperadrenocorticism, is caused by elevated cortisol produced by the pituitary or adrenal gland tumors. Cushing's disease has a higher incidence in dogs than in cats. Clinical signs include weight gain, a pot-bellied appearance, increased drinking and urination, lethargy, and muscle weakness.
High levels of glucose may indicate diabetes mellitus. High levels of thyroxine may indicate hyperthyroidism. High levels of luteinizing hormone occur prior to ovulation in intact female dogs.
NEW QUESTION # 328
Which of the following does not describe root planing?
Answer: C
Explanation:
Subgingival curettage actually describes the process of removing infected soft tissue from periodontal pockets. One can use a curette or periodontal incision.
Root planing helps remove any gross calculus and cementum around the tooth root using a curette. One uses various strokes in various directions to achieve this.
Root planing also removes microorganisms and toxins that have caused necrotic debris along the periodontium.
Root planing can be done closed, when no flap is needed for areas less than 4 mm in depth. Sometimes, open root planing using a gingival flap to access the debris may be required.
It is adequate to only remove superficial layers of cementum to achieve periodontal debridement, the goal of root planing.
NEW QUESTION # 329
What correctly describes the purpose and use of a control when referring to practices to ensure laboratory instrumentation and procedures work as needed?
Answer: A
Explanation:
Controls monitor a test's performance and make sure that the procedure/test runs smoothly and correctly. They examine a machine or kit's performance to ensure the instrument or test/procedure works consistently and accurately. They are used on consistent schedules to check the instrument's performance independently or the entire analytical process. Controls should be used daily, before any patient samples are run for the day.
Controls are commercially available and may include normal and abnormal controls or, for some equipment, low, normal and high controls to ensure that the analyte's high and low values remain in proper working order.
Some point-of-care units, such as iSTAT, use a single-use cartridge. The electromechanical methods do not allow in-house calibration because the individual cartridge is calibrated at manufacture. But this means that it is even more critical that patient sampling, using the correct sample type, minimizing hemolysis on venipuncture, and cartridge loading are all done correctly to ensure accurate and consistent results.
NEW QUESTION # 330
What is extra-label drug use?
Answer: A
Explanation:
Extra-label drug use, sometimes referred to as "off-label drug use", is the use of a drug in ways other than those listed on an FDA-approved label. This could include use for a different species, other disease states, different dosages, or even another mode of administration. Extra-label drug use is often advantageous, even necessary. It allows veterinarians to use medications in ways that have not yet been thoroughly tested or approved for a specific species, but may still be helpful. This practice is regulated by the Animal Medicinal Drug Use Clarification Act and is not permitted in food-producing animals.
The administration of several medications in combination could involve extra-label use of one or more of the drugs. However, generally, extra-label use refers to the administration of one drug. The use of drugs that have not been approved by the FDA is incorrect because extra-label drug use involves an FDA-approved drug, but it is used in a manner not listed on the FDA-approved label. The compounding of a number of substances to arrive at a single therapeutic compound otherwise unavailable is incorrect because extra-label drug use does not require the compounding of several substances.
NEW QUESTION # 331
Which cell type would new methylene blue help best identify on cytology?
Answer: B
Explanation:
Mast cells, round to oval cells with round to oval nuclei, often contain numerous blue to dark purple granules within the cytoplasm. New methylene blue effectively stains nuclei, mast cells, and many infectious agents. Typically, mast cells are found near blood vessels, allowing them to quickly release the contents of the granules (histamine and heparin). This allows them to be protective and guard against infection and abnormal proteins. When stimulated, they burst open, releasing the granules. When they proliferate in other places, however, they can become neoplastic. Knowing how to identify these cells is paramount. They can be identified with other stains such as Diff-Quik, but the granules stain much darker and clearer with new methylene blue.
The remaining cells can be identified by a variety of stains, most commonly, Diff-Quik.
