Surgery Quiz 04 Quiz InstructionsThis quiz consists of 20 multiple-choice questions.You will be awarded 5 marks for each correct answer. Question 1: In shock more common isRespiratory acidosisMetabolic acidosisRespiratory alkalosisMetabolic alkalosis Question 2: Most of the clinical signs seen in animals in shock related to excessive blood loss are attributable toAcidosisAlkalosisRedistribution of blood flowTissue hyperoxia Question 3: Drug induced state of sleep may or may not be accompanied by analgesia is known asHypnosisNacrosisTranquilizationNone of the above Question 4: Which of the following is not an objective of preanaesthetic medication?Alleviate or minimize painMinimize undersirable post anaesthetic recovery complicationsIncrease reflex autonomic activityDecrease the dose of parenteral anesthetic induction drugs Question 5: Atropine acts on the parasympathetic nervous system byDepressing formation of acetylcholineEnhancing formation of cholinesteraseDirectly inhibiting neurochemical reactions at the myoneural junctionCompetitive anatagonism of acetylcholine Question 6: Bradycardia during general anesthesia of dogs can be treated with intravenous atropine, usually at 0.01 to 0.02 mg/kg. If the bradycardia worsens after atropine administration, the most appropriate course of action is toRepeat the dose after 1 or 2 minutesWait for atropine to cause it's sympathetic effectCease administration of anaesthetic and insuffiate with OxygenAdminister epinephrine intravenously Question 7: One of the differences between atropine and glycopyrrolate is thatGlycopyrrolate causes a greater increase in the heart rate than atropineGlycopyrrolate causes a smaller increase in the heart rate than atropineAtropine is longer acting than glycopyrrolateAtropine can be antagonized by epinephrine but glycopyrrolate cannot Question 8: Which is not an action of phenothiazine tranquilizers on the nervous system?AntiemeticSympathomimeticPotentiate seizuresSedation Question 9: Acepromazine is classified asA alpha 2 adrenergic agonistA phenothiazine tranquilizersAn anticholinergicAn opioid Question 10: In horses acepromazine should be used with caution inPregnent maresHorses with pre-existing second degree atrioventricular blockWorking stallionAdult draft stallion Question 11: Guaifenesin, a muscle relaxant commonly used for large animal anesthesiaActs at myoneural junctionCauses profound cardiac depressionDoes not provide analgesiaCauses respiratory paralysis because f it's muscle relaxant properties Question 12: A drug with a similar mechanism of action to guaifenesin isDiazepamGlycopyrrolateButorphanolSuccinylcholine Question 13: In horses the lethal effects of gauifenesinAre primarily manifested by respiratory center depressionAre not seen because such large volumes must be administeredAre primarily manifested by skeletal muscle relaxation resulting in respiratory muscle paralysisAre seen at 3 to 4 times the therapeutic dose Question 14: AtracuriumReduces the requirement for inhalation an aesthesia because of its analgesic propertiesIs a central acting muscle relaxantCrosses the placental barrierShould not be used unless patients are receiving intermittent positive pressure ventilation Question 15: Elimination of atracurium from the bodyProduces the metabolite laudanosine , which depresses cwntral nervous system functionIs enhanced by its inherent instability at body temperature and pHIs prolonged I patients with both renal and hepatic diseaseIs prolonged following intravenous infusion Question 16: Atracurium has advantages over succinylcholine in thatIt has a shorter duration of actionIt does it cause ganglionic biockadeIt does not caused Muscle rigidityReversal of succinylcholine requires administration of neostigmine Question 17: In an anaesthetised patients with profound bradycardia, injection of neostigmineExacerbates the bradycardiaRapidly resolves the bradycardiaDoes not change the heart rateCauses sudden arousal of the anaesthetised animal Question 18: Which of the following is most selective alpha 2 adrenoceptor agonist?XylazineDetomidineMedetomidineDexmedetomidine Question 19: Which is a alpha 2 adrenoceptor agonist?ClonidineXylazineRomifidineAll of the above Question 20: Which is alpha 2 adrenoceptor antagonist?YohimbineTolazolineAtipamazoleAll of the above
