Wild Card Flashcards
You are about to perform a myelogram and there are two bottles of iodinated contrast medium on the shelf: ionic (Hypaque-76) and nonionic (Omnipaque). Which one do you choose, and why?
Nonionic iodinated contrast medium (Omnipaque), because injection of ionic iodinated contrast medium into the subarachnoid space is strictly contraindicated (causes fluid shifts into the space that are usually fatal).
When administering a drug to a food animal, established withdrawal times only apply if which condition is met?
Only is the drug is used according to the approved labelling.
What is the definition of specific gravity?
Specific gravity refers to the ratio of the weight of a volume of liquid to the weight of an equal volume of distilled water. Therefore, specific gravity depends on the molecular weight of particles as well as the number present in the solution.
Which of the following antibiotics best crosses the normal blood-brain barrier?
A) Amoxicillin-Clavulanate
B) Cefazolin
C) Chloramphenicol
D) Gentamicin
C) Chloramphenicol
Which describes a true hermaphrodite?
A) Chromosomal and gonadal sex agree, phenotypic sex and tubular organs are modified towards the other sex
B) Chromosomal and gonadal sex reversed
C) Both ovarian and testicular tissue present
D) Gonadal and tubular sex are reversed
A) Chromosomal and gonadal sex agree, phenotypic sex and tubular organs are modified towards the other sex
Which of the following species is most sensitive to xylazine - cats, cows, dogs, horses, rabbits?
Cows
In which intervertebral space would an epidural injection be given to provide regional anesthesia for procedures performed caudal to the umbilicus in a dog?
Between the seventh lumbar vertebra (L7) and the first sacral vertebra (S1).
Stage III of labor ends with what?
A) Dilation of the cervix
B) Entry of the fetus into the pelvic canal
C) Delivery of the fetus
D) Delivery of the placenta
D) Delivery of the placenta
Through which developmental zone of the physis do fractures typically occur?
Zone of hypertrophy
Name 2 factors that can influence the effectiveness of a disinfectant.
1) Organic debris
2) Concentration
3) Temperature
4) Contact time
Organic debris can inactivate disinfectants, which is why cleaning before disinfection is essential.
Which 3 vessels are part of the circle of Willis (also called the arterial circle of the brain)?
The right and left internal carotid arteries, and the basilar artery form an elongated arterial ring on the ventral surface of the brain.
Where are the Renshaw cells located, and what is their function?
Ventral horns of the spinal cord; they are inhibitory neurons that transmit inhibitory signals to surrounding motor neurons.
Which structure is primarily responsible for preventing caudal displacement of the femur and cranial displacement of the tibia in the stifle?
The cranial cruciate ligament
The lesions of pyogranulomatous nephritis that are associated with the non-effusive/’‘dry’’ form of feline infectious peritonitis are related to which type of hypersensitivity reaction?
Type IV - delayed hypersensitivity
In acid-base balance, what does the law of electroneutrality stipulate?
The sum of all cations must equal the sum of all anions (in body fluids).
Isolation guidelines for human medicine target the prevention of five different types of transmission of infectious diseases. Name 2.
1) Contact transmission
2) Droplet transmission
3) Airborne transmission
4) Common vehicle transmission
5) Vector-borne transmission
Rapid blood loss causes fatal hypovolemic shock after approximately which proportion of the blood volume is lost?
A) 10-15%
B) 25-30%
C) 40-45%
D) 55-60%
C) 40-45%
What is the definition of an outbreak of a disease?
An increased occurrence of infections above the expected baseline (endemic) level.
In a case with angular limb deformity, what does the term ‘‘valgus’’ mean?
Lateral deviation of the limb distal to the origin of the deformity.
In the adult, haematopoietically active bone marrow can be collected from which anatomical locations?
Flat bones (Sternum, ribs, pelvis, vertebrae) and proximal ends of long bones (Humerus, femur)
A dog with acute renal failure has a positive serum titer for Leptospira interrogans, serovar hardjo. The dog was vaccinated 2 months earlier. Is this titer related to vaccination?
No. Vaccines protect against serovars icterohaemorrhagiae and canicola (conventional) or, additionnally, also pomona and gryppothyphosa (newer vaccines). No vaccine protects against hargjo, autumnalis, bratislava or others.
Name 3 protozoal causes of splenomegaly in the dog and/or cat.
Babesiosis, cytauxzoonosis, hepatozoonosis, leishmaniasis, toxoplasmosis, trypanosomiasis.
Name 4 round cell tumors.
1) Lymphoma
2) Mast cell tumor
3) Plasmocytoma
4) Histiocytoma
5) Transmissible veneral tumor
The Somogyi response can be seen as a complication of insulin therapy for diabetes mellitus. What is this response?
The Somogyi response is insulin-induced hypoglycemia leading to counterregulatory glycogenolysis and secretion of glucagon and epinephrine, which results in severe hyperglycemia (rebound effect). This explains the need for blood glucose curves in patients with poorly controlled diabetes receiving increasing dosages of insulin,
