1、北美执业兽医考试中英双语版1. 一只4岁雌性已绝育哈士奇由于眼睛，鼻子和嘴巴周围出现的如下图所示的结痂和角化过度转诊而来。皮肤刮片检查未找出病因。你会怎样治疗这只狗？ 单选题 *Zinc supplementation 补充锌(正确答案)Daily wiping with chlorhexidine pads 每天用洗必泰擦拭Corticosteroids 糖皮质激素Ivermectin treatment 伊维菌素答案解析：Zinc responsive dermatopathy occurs most frequently in the Siberian Husky. Other spec

2、ies such as cattle, goats, and humans have a similar condition. The exact cause is unknown, but it has been linked to defective intestinal absorption of zinc. Lesions may vary in severity. The response is typically seen within days. The key to answering this question appropriately was to recognize t

3、he signalment of the patient, the location of the lesions which is characteristic of zinc responsive dermatopathy, and the fact that there was no infectious etiology such as demodex identified.锌反应性皮肤病最常见于哈士奇犬。其他物种入牛，羊和人也有相似的问题。根本的病因未知，但已经证明该病与肠道内锌的吸收不良有关。病情不同症状差别可能较大。但治疗后会在几天内有好转。回答这道问题的关键点在于认识病患的特点

4、，病变的位置是典型的锌反应性皮肤病的好发部位以及没有找到其他如蠕型螨之类的感染性原因。2. Which diseases are classically associated with a high anion gap (AG)?哪种疾病很典型得与阴离子间隙升高有关？*单选题 *Eosinophilic enteritis, hypothyroidism, gastrinoma 嗜酸性粒细胞性肠炎，甲状腺机能减退，胃泌素瘤Prostatic adenocarcinoma, pleural effusion, lymphangiectasia 前列腺癌，胸腔积液，淋巴管扩张Diabetes me

5、llitus, pancreatitis, proliferative enteritis 糖尿病，胰腺炎，增生性肠炎Hypercalcemia of malignancy, hypoadrenocorticism, displaced abomasum 癌症导致的高血钙，肾上腺机能减退，真胃变位Grain overload, ethylene glycol toxicity, renal failure 食物过载，乙二醇中毒，肾衰(正确答案)答案解析：Typically, expect an increased anion gap with: Diabetic ketoacidosis，Re

6、nal failure，Ethylene glycol toxicity，Lactic acidosis from grain overload or strenuous exercise. Anion gap is typically measured as positive cations (Na+, K+) minus negative anions (Total CO2, Cl-). You can also calculate AG using HCO3- in place of TCO2. Anion gap = (sodium + potassium) - (TCO2 + chl

7、oride). Decreased anion gap is UNcommon. Think hemodilution, hypoalbuminemia, hypercalcemia.一般情况下在糖尿病酮酸中毒，肾衰，乙二醇中毒，粮食过载导致的乳酸酸中毒或剧烈运动后看到明显的阴离子间隙升高。一般来说，阴离子间隙由带正电荷的阳离子（Na+，K+）减去带负电荷的阴离子（总CO2，Cl-）得到。你还可以使用HCO3-代替TCO2来计算AG。AG=（钠离子+钾离子）-（TCO2+氯离子）。阴离子间隙降低的原因未知Abdominocentesis reveals sanguineous fluid. H

8、ow can you determine that it is fresh blood rather than just hemorrhagic fluid?3. 3. 腹腔穿刺液为血样。你该怎样区分这些是新鲜血液还是血性液体？ 单选题 *See if it clots 看它是否凝结(正确答案)Measure lactate 检测其乳酸值Evaluate red blood cell morphology microscopically 显微镜检查红细胞形态Take another sample, and check color 再次穿刺采样看其颜色Measure viscosity 检测其黏

9、度答案解析：If sanguineous fluid from abdominocentesis clots, it is fresh blood rather than just free hemorrhagic fluid from within the abdomen.如果腹腔穿刺液凝结了，则说明它是新鲜血液而不仅仅是血性液体。考虑血液稀释，低白蛋白血症，高血钙。4. 4. A surgical repair of a patent ductus arteriosus was performed via thoracotomy in a four-month-old Labrador p

10、uppy. In recovery, the puppy is found in his cage, crying and whining. His breaths are short and fast. When a technician attempts to comfort him, he tries to get away, cowers in the corner, and cries louder. Which of the following is the best explanation of this scenario?一只4月龄的拉布拉多接受了开胸手术治疗动脉导管未闭。在麻

11、醉复苏阶段发现该犬在笼子里嚎叫哀鸣。他的呼吸短而快。当有人尝试接近安抚他时，他一边叫一边躲到角落里叫得更大声了。以下哪个选项解释了这个情况？*单选题 *Recovery is prolonged, stage II signs are still occurring 苏醒期延长，II 期表现依旧存在The patient has cerebral hypoxia, likely due to sustained hypotension 动物出现脑组织缺氧，可能由于术中低血压导致This puppy is painful, pain management is inadequate 该犬感受到了

12、疼痛，疼痛管理不足(正确答案)Labradors often do this in recovery, they have low pain tolerance 拉布拉多犬常常在苏醒期有这种表现，因为它们对疼痛耐受性差答案解析：This puppy is painful, pain management is inadequate, as these are signs of pain. Behavioral changes are the most reliable signs of pain in animals.Tolerance levels and socialization ski

13、lls certainly vary in all species, however, signs of pain should be anticipated, repeatedly evaluated, and treated in all cases. A thoracotomy is one of the most painful procedures performed in animals and humans. Intense pain management is required, including: 1) an opioid in combination with a tra

14、nquilizer or sedative, 2) a non-steroidal anti-inflammatory agent, and 3) intercostal and intrapleural nerve blocks with a long acting local anesthetic, e.g. bupivacaine. Continuous infusion of lidocaine, ketamine, and/or an opioid such as fentanyl or morphine provides excellent analgesia and some s

15、edation. This can replace # 1 above. Shallow respiration is common in patients with chest pain; hypoventilation and hypoxemia can result. Opioids can depress respiratory function, but adequate pain management will improve ventilation when it doesnt hurt so much to breathe. Although labrador puppies

16、are generally most gregarious and responsive to people, they still exhibit signs of pain when present. Sometimes we need to look very closely; dont believe that wagging tail!这只狗的表现说明疼痛管理不足。行为改变是判断动物是否处于疼痛状态中的可靠手段。不同动物的疼痛耐受水平以及互动技能不尽相同，所以需要重复进行疼痛评估并且在任何需要的情况下给予治疗。开胸手术是动物和人类中疼痛级别最高的一种手术之一。需要高级的疼痛管理，包括

17、1）阿片类药物配合镇静药物 2）非甾体类抗炎药结合3）使用长效局部麻醉药如布比卡因进行肋间神经和胸膜内神经阻断。衡速输注利多卡因，氯氨酮和/或阿片类药物如芬太尼或吗啡都可以提供很好的镇痛和镇静效果。这些可以结合1）来使用。胸腔疼痛的动物常常表现浅快的呼吸，可能会导致通气不足和低血氧。阿片类药物会导致呼吸抑制，但是镇痛到位可以帮助改善通气所以当不那么痛的时候呼吸也就会好很多了。虽然拉布拉多幼犬对人十分友好喜欢亲近人类，但他们感受到疼痛时也会表现出来。有时我们需要细心观察，不要相信那根摇来摇去的尾巴！5. 5. Which direction is caudal?caudal是指哪个方向？*单选题

18、 *Towards the tail 朝向尾巴(正确答案)Towards the belly 朝向肚子Towards the left side 朝向左边Towards the nose 朝向鼻子答案解析：Caudal means towards the tail/hind end. caudal是指朝向尾巴/尾侧Rostral means towards the nose. rostral是指吻端Cranial means towards the head. cranial是指朝向头部Ventral is towards the ground. ventral是指朝向地面Dorsal mea

What kind of problem may result in waxy casts in the urine sediment of a dog?一只犬的尿沉渣检查发现蜡样管型提示什么问题？*单选题 *Glomerular leakage 肾小球泄漏Chronic renal tubular degeneration 慢性肾小管退化(正确答案)Pyelonephritis (kidney infection) 肾盂肾炎（肾脏感染）Renal

21、 hemorrhage 肾出血答案解析：Waxy casts in a urine sediment are thought to be older versions of granular casts, and may indicate chronic to severe renal tubular degeneration.They are wide, blunt or square-ended, and opaque. Look for cellular casts (recognizable cells in cast) like sloughed epithelial cells,

22、or red blood cells with renal hemorrhage, or white blood cells with pyelonephritis (kidney infection). Look for hyaline casts (clear, semitransparent) with mild glomerular leakage. You may also see granular casts (common, nonspecific, made of degenerating cells) or fatty casts in some cats.尿沉渣中的蜡样管型

23、被认为是老化的颗粒管型，可能提示慢性或严重的肾小管退化。它们一般为透明，较宽且钝圆或方头状。肾出血可能会见到细胞管型（管型明显由细胞组成）如堆叠在一起的上皮细胞或红细胞，肾盂肾炎时可见白细胞管型。一些猫上面你可能会见到颗粒管型（常见，无特殊意义，由退化细胞组成）。7.

24、答案)答案解析：When Canine parvovirus mainly affects puppies and young dogs less than a year of age. Transmission of the virus is through contact with infected feces and fomites such as hands, toys, the dogs hair coat. The virus is very resilient in the environment and is resistant to many types of disinfe

25、ctants. It replicates in the crypt epithelium of the gut and causes epithelial necrosis and hemorrhagic diarrhea. The virus can also affect the heart of young puppies, causing myocarditis. This occurs less commonly now since most bitches are immunized against the virus, which allows for maternal ant

26、ibodies to protect young puppies from this form of the disease.犬细小病毒一般感染幼犬或一岁以下的犬。传播途径包括接触感染的粪便或污染物如手，玩具或犬的被毛等。病毒在环境中适应能力很强并且可以抵抗多种消毒剂。病毒在肠上皮隐窝中复制导致上皮坏死以及出血性腹泻。病毒同样可能侵犯幼犬等心肌导致心肌炎。由于现在多数母犬都接种了疫苗使幼犬可以从母犬那里得到抗体，这个问题已经很少见了。8.

It requires prolonged, close contact. Cats may shed the virus for mon

34、ths to years. Transmission may also occur through reuse of instruments and blood. Virus is shed in saliva, tears, urine, and feces.主要转播方式为唾液传播。需要长时间密切的接触。病猫会持续数月甚至数年的排毒。也会通过重复使用的器械和血液传播。病毒通过唾液，眼泪，粪尿排出。12. 12. An adopted adult male cat from a shelter with an unknown vaccination history is presented.

35、The cat tests positive for feline leukemia virus (FeLV) infection by IFA. What should the owner be told?你接诊了一只疫苗史不清的从救助站领养的成年公猫。这只猫免疫荧光检测FeLV为阳性。应该告知主人什么？*单选题 *Possible transient FeLV infection 可能是FeLV的一过性感染Need an ELISA test in 12 weeks to confirm diagnosis 需要在12周后做ELISA检测确诊Cat may be vaccinated fo

36、r FeLV 这只猫可能打过FeLV疫苗Need a Western blot test to confirm diagnosis 需要做蛋白印迹试验确诊Strong chance of lifelong FeLV infection 很可能出现FeLV终身感染(正确答案)答案解析：97% of cats positive for feline leukemia virus (FeLV) by IFA remain persistently infected and viremic for life. The FeLV ELISA is more seNsitive than the IFA

37、(fewer false Negs, so trust a NEG test more), so it is a better general screening test with which to start. The FeLV IFA is more sPecific than the ELISA, (fewer false Pos, so trust a POS test more) so it is a better confirmatory test for any cats with a positive FeLV ELISA.97%的IFA测试FeLV阳性的猫很可能出现持续感染

38、和终身病毒血症。FeLV的ELISA测试比IFA敏感（假阴性更少，所以阴性结果更可信），所以是一个更好的筛查方式。FeLV的IFA测试比ELISA准确性更高（假阳性更少，所以阳性结果更可靠），所以是FeLV的ELISA检测阳性猫更好的确诊性检测。THREE things to remember about FeLV and vaccinations: 关于FeLV和疫苗需要记住的三点：1. FeLV ELISA and IFA tests measure ANTIGEN, not antibody, so FeLV vaccination does NOT interfere with tes

39、ting. FeLV的ELISA和IFA检测的是抗原，不是抗体，所以FeLV疫苗不会影响检测结果。2.Vaccinate FeLV-positive cats yearly against respiratory, enteric viruses with inactivated vaccines. 每年给FeLV阳性的猫接种灭活疫苗可以预防呼吸道和肠道病毒。3. FeLV vaccination for FeLV-negative cats has been associated with sarcomas. Vaccinate LOW on the LEFT hind. FeLV阴性猫的F

51、sia. The kitten was having severe diarrhea around the house when it became ill. The owner has a 2 year old cat at home and wants to know what this cats prognosis is since it has been exposed to the sick kitten. Currently this cat is clinically healthy. What do you tell her？这是一只8个月大的小猫，患有猫传染性腹膜炎，并进行了

52、安乐死。 她之前生病时，在家里有严重的腹泻。 畜主在家里还有一只2岁的猫，这只猫暴露在FIP小猫的生活环境里，所以他想知道这只猫的预后是什么。 目前这只猫没有临床表现。 你应该告诉他什么？*单选题 *Perform a PCR on the cats feces to see if the virus is being shed 对猫的粪便进行PCR检测，看是否能检测到病毒Place the cat on L-lysine to prevent or suppress any infection with FIP 给猫吃L-赖氨酸，以防止或抑制FIP感染You recommend a coro

53、navirus titer to determine it the cat is actively infected 建议使用冠状病毒滴度检测来确定猫是否被感染Feline infectious peritonitis is not contagious and because her other cat died of FIP does not mean this cat will succumb to the disease 猫传染性腹膜炎是没有传染性的，虽然那只小猫死于FIP但这并不意味着这只猫也会死于这个疾病(正确答案)Her other cat may develop symptom

54、s within the next two weeks because FIP is highly contagious 她的另一只猫可能在接下来的两周内出现症状，因为FIP具有高度的传染性答案解析：Feline infectious peritonitis is not a contagious disease. It is a disease that is caused by a mutation of feline enteric coronavirus. It is unknown why in some patients this virus mutates and causes

55、the FIP syndrome. It is most likely to occur in young or immunocompromised cats. Her other cat is not necessarily going to get FIP just from exposure. In fact, the majority of the cat population has been exposed to the feline enteric coronavirus. Because most cats in the general population have been

56、 exposed, it makes interpretation of coronavirus titers difficult. The titers can be elevated due to prior exposure and not from FIP. The titers can only be interpreted in lieu of clinical signs, blood results, etc. L-lysine is an anti-viral medication that may have some benefit for suppression猫传染性腹

57、膜炎并不是一种传染病。这是一种由肠道冠状病毒突变而引起的疾病。目前尚不清楚为什么在某些患者中这种病毒会发生突变并引发FIP。它最有可能发生在年轻或免疫功能低下的猫身上。另一只猫并不一定会因为暴露在FIP病患的环境下而感染上病毒。事实上，大多数猫的生活环境中都有肠冠状病毒。由于大多数猫的生活环境中都有肠冠状病毒，因此难以解释冠状病毒滴度。病毒滴度的升高可能会是由于环境的暴露而不是来自于FIP。滴度检测只能用来解释临床症状和血液结果。L-赖氨酸是一种抗病毒药物，可能对抑制疱疹病毒有一定的益处，但它不用于冠状病毒的预防或治疗。在冠状病毒活动期间，冠状病毒会在猫的粪便中排除。但其中一些受感染的猫并不会

58、排出病毒。病毒攻击肠道会引起胃肠道的不适。我们可以用PCR检测粪便中的冠状病毒，但无法区分该病毒是肠冠状病毒，还是它突变形成的FIP病毒形式。17. The veterinarian at your clinic tells you that a dog is coming in with dystocia. What is happening?你诊所的兽医告诉你，一只狗因为难产而来就诊。这意味着什么？*单选题 *Trouble breathing 呼吸困难Unable to urinate 无法排尿Trouble giving birth 分娩困难(正确答案)Dog is temporari
