The test is implemented in two sessions. The first session is four hours, from 7:00 am and the second of four hours, starting at 1:30 pm The test structure is as follows:
Question Types and Examples
ECAES In veterinary medicine and animal husbandry will use four (4) types of questions:
single answer multiple choice, multiple answer multiple-choice analysis, assumptions and analysis relationship.
multiple choice questions only answer
Below you will find questions that consist of a statement and four (4) response options. You must mark your answer sheet that option you think is correct.
Examples 1. In a Schnauzer dog breed 10 years of age, fed with homemade food.
reported: occasional vomiting, emaciation progressive hair loss and loss of appetite. Clinical examination and abdominal tenderness subictéricas mucous. The clinical suspicion of liver disease, which can be confirmed by the determination of
A. BUN.
B. aspartate aminotransferase.
C. alanine aminotransferase.
D. free bilirubin.
B. aspartate aminotransferase.
C. alanine aminotransferase.
D. free bilirubin.
Key: C
Competition: Purpose
Rationale: ALT is the enzyme hepatoespecĂfica of canine
Competition: Purpose
Rationale: ALT is the enzyme hepatoespecĂfica of canine
2. Isabelo color or clear Palomino horses can be obtained from matings horse chestnut mares cremillas (white yellow) or the reciprocal cross. Obtaining this new color (Palomino), is explained by the type of inheritance called.
A. epistatic interaction.
B. no epistatic interaction.
C. codominance incomplete.
D. overdominance.
Key: C
Competition: Interpretative
Justification: incomplete dominance, each allele has a variable degree of expression. Furthermore, the genotypic proportions correspond to the phenotypic ratios.
Competition: Interpretative
Justification: incomplete dominance, each allele has a variable degree of expression. Furthermore, the genotypic proportions correspond to the phenotypic ratios.
3. One experiment assessed 7 varieties of grass, which will be planted actual plots of 40 m2 located on four lots. The experimental design used is
A. completely random.
B. randomized block.
C. the Latin square.
D. factorial arrangement with completely randomized design.
B. randomized block.
C. the Latin square.
D. factorial arrangement with completely randomized design.
Key: B
Competition: Interpretative
Rationale: The correct design is the randomized block, in this case has 4 blocks and 7 treatments. As for the placement of the blocks in the field, look for homogeneous soil conditions for each, according to the example, each batch is considered as a homogeneous block and soil characteristics.
Competition: Interpretative
Rationale: The correct design is the randomized block, in this case has 4 blocks and 7 treatments. As for the placement of the blocks in the field, look for homogeneous soil conditions for each, according to the example, each batch is considered as a homogeneous block and soil characteristics.
multiple choice questions with multiple choice
Here are some questions that consist of a statement and four (4) response options. Two or more options may successfully complete the sentence. You must mark your answer sheet according to the following table:
4. A beef cattle 5 years has pale mucous membranes, decreased appetite, progressive weight loss, swelling of the chin. The laboratory reported: Ht: 12%, Hb: 3 g / dl, RE: 1.5 X 106, MCV: 80, Fl, MCHC: 25, IPR 1.3. Benchmarks
Ht: 28-38%, Hb: 8-15 g / dl, RE: 6.5-9.0 x 106, VCM: 37.51, Fl, MCHC: 33-37, IPR: 0 - 0 4
The type of anemia that is evident in the animal's regenerative
1. Hypochromic microcytic
2. Hypochromic macrocytic
3.
4 no regeneration.
Key: B
Competition: Interpretative
Justification: there is regeneration by the reticulocyte production index (MPI). MCV and MCHC indicate macrocytic hypochromic anemia.
5. In dual purpose herd located in warm weather, production has decreased by 15% during the last week, no changes in management to justify the problem. Possible causes of the decline in production can be:
1. the low availability of drinking water.
2. the reduced availability of fodder and feed.
3. the noticeable increase in tick infestation.
4. exacerbation of a latent internal parasitism.
Key: A
Competition:
Argumentative Justification: The production will be altered by reduction in dietary components and by a parasitic infestation. For internal parasites cause decrease in production should occur exacerbation of a possible latency.
analysis postulates Questions
The questions below consist of a thesis and two postulates TRUE TRUE also identified with the numbers I and II. You must decide if the conclusion follows logically from the thesis and answer according to the following table:
6. From day 60 of gestation in sheep depends on the secretion of progesterone by the placenta. THEREFORE
I. The induction of abortion in cases of toxemia of pregnancy can only be done with glucocorticosteroids.
II. The induction of abortion requires the elimination of the synthesis of progesterone by the placenta.
Key: A
Competition: Argumentative
Rationale: Option I. To induce abortion in sheep after day 60 of gestation should be administered glucocorticoids. But we can not conclude the thesis that the toxemia of pregnancy occurs after day 60 of gestation and that the sheep requires glucocorticoids for induction of abortion after day 60 of gestation.
Option II.
Yes we can conclude the thesis, it is said that progesterone after day 60 is only secreted by the placenta and therefore eliminate the synthesis of progesterone by the placenta lead to abortion. Reference: Van Saun, RJ Pregnancy toxemia in a flock of sheep. Journal of The American Veterinary Medicine Association. 2000 Nov. 15, 217 (10) :1536-9.
7. AST is found in small amounts in red blood cells. THEREFORE
I. Hemolyzed sample can cause variation of the results of the laboratory.
II. The AST is diagnostic in case of damage to muscle cells.
Key: B
Competition: Argumentative
Rationale: The AST is found in red blood cells and can cause variation in results when the sample is haemolysed.
relationship analysis questions
Here are some questions that consist of a statement and reason together with the word WHY. You must judge both the degree of truth or falsity of each of them as the relationship between them and answer in your answer sheet according to the following table:
8. In pigs the administration of prostaglandin is not often used to induce estrus BECAUSE
in pig corpus luteum is sensitive to prostaglandin only at 15-17 days of the estrous cycle.
Key: A
Competition:
Argumentative Justification: The pig is one of the few species where the corpus luteum remains refractory to prostaglandin until day 15-17, when endogenous prostaglandin is released. Therefore it is not practical since prostaglandin would get the same effect as endogenous prostaglandin.
9. antisepsis are all steps to eliminate germs and surgical equipment installations
BECAUSE
Key: D
Competition: Interpretative.
Rationale: antisepsis is made in the skin of the surgeon and patient, not in facilities and equipment.
10. disease Leg-Calve-Perthes disease (avascular necrosis of the femoral head) affects young animals and is diagnosed by radiology
BECAUSE
Key: C
Competition: Argumentative
Rationale: The statement is correct and that the disease is diagnosed with a high degree of reliability by radiological assessment. The reason is false and that the angle measured Norbert hip dysplasia.
