Question 1Anesthesia and Analgesia

Which agent is most appropriate for premedication in a healthy, fractious cat that needs to be handled for an IV catheter placement before induction?

  1. Atropine sulfate
  2. Ketamine alone
  3. Midazolam alone
  4. Dexmedetomidine with an opioid Correct answer.

Explanation

Alpha-2 agonists such as dexmedetomidine combined with an opioid produce reliable sedation and handling ease in healthy, aggressive cats while reducing anesthetic induction doses. Atropine is an anticholinergic and does not sedate. Ketamine alone can cause rough recoveries and increased muscle tone.

Question 2Anesthesia and Analgesia

Which crystal or fluid is isotonic and commonly used for maintenance in small animal anesthesia?

  1. Lactated Ringer's solution Correct answer.
  2. 0.9% sodium chloride
  3. 5% dextrose in water
  4. Hypertonic saline (7.2%)

Explanation

Lactated Ringer's solution is an isotonic balanced crystalloid used for maintenance and replacement in anesthetized patients. 5% dextrose in water is hypotonic after dextrose metabolism and provides no electrolytes. Hypertonic saline is used for resuscitation, not maintenance.

Question 3Anesthesia and Analgesia

A dog is breathing spontaneously through a tight-fitting mask with an oxygen flow of 2 L/min. Which statement about this technique is correct?

  1. It produces less dead space and better oxygenation than a tight mask alone
  2. It delivers a reliable fraction of inspired oxygen above 90%
  3. It provides an unpredictable FiO2 and may cause CO2 rebreathing Correct answer.
  4. It is only effective if the patient is intubated

Explanation

Mask breathing with a tight-fitting mask provides an unpredictable and often low inspired oxygen fraction and can cause rebreathing of carbon dioxide. It is not a reliable method for controlled oxygen delivery in an anesthetized patient.

Question 4Anesthesia and Analgesia

Which monitoring finding most strongly suggests that an anesthetized patient is too lightly anesthetized?

  1. Pale mucous membranes with prolonged CRT
  2. Increased jaw tone and nystagmus Correct answer.
  3. Bradycardia with a stable blood pressure
  4. Decreased respiratory rate with a stable heart rate

Explanation

Increased jaw tone, nystagmus, and limb withdrawal are signs of inadequate anesthetic depth. These indicate the patient may respond to surgical stimulation and needs deeper anesthesia. Cardiovascular depression and pale membranes suggest excessive depth or poor perfusion.

Question 5Anesthesia and Analgesia

A 20 kg dog receives a constant rate infusion of fentanyl at 5 µg/kg/hr. What is the hourly dose in micrograms?

  1. 100 µg/hr Correct answer.
  2. 200 µg/hr
  3. 10 µg/hr
  4. 50 µg/hr

Explanation

The dose is calculated as 5 µg/kg/hr × 20 kg = 100 µg/hr. This is a direct multiplication of the weight-based rate by the patient's body weight.

Question 6Anesthesia and Analgesia

Which inhalant agent has the lowest blood-gas partition coefficient and therefore the fastest induction and recovery?

  1. Halothane
  2. Sevoflurane
  3. Desflurane Correct answer.
  4. Isoflurane

Explanation

Desflurane has the lowest blood-gas partition coefficient among the listed agents, giving the fastest equilibration and recovery. Sevoflurane is faster than isoflurane but slower than desflurane. Halothane has the highest coefficient and slowest recovery.

Question 7Anesthesia and Analgesia

A patient under general anesthesia has a sudden drop in end-tidal CO2 from 40 to 15 mmHg with a concurrent drop in blood pressure. Which is the most likely cause?

  1. Hypercapnia
  2. Hypothermia
  3. Decreased cardiac output Correct answer.
  4. Light anesthesia

Explanation

A sudden fall in end-tidal CO2 with hypotension most likely reflects decreased pulmonary blood flow due to reduced cardiac output, such as from hemorrhage or cardiovascular collapse. Light anesthesia and hypercapnia would raise end-tidal CO2.

Question 8Anesthesia and Analgesia

Which analgesic technique provides preemptive and multimodal pain control by blocking peripheral nociception before surgery?

  1. Postoperative opioid administration
  2. Local anesthetic infiltration at the surgical site Correct answer.
  3. Intraoperative dobutamine infusion
  4. Intraoperative isoflurane alone

Explanation

Local anesthetic infiltration before incision blocks nociceptive input at the source and is a preemptive, multimodal analgesic technique. Opioids given postoperatively treat pain after it begins. Isoflurane and dobutamine are not analgesics.

Question 9Anesthesia and Analgesia

What is the primary purpose of preoxygenation immediately before induction in a high-risk patient?

  1. To increase the alveolar oxygen reservoir and delay desaturation during apnea Correct answer.
  2. To increase the MAC of the inhalant agent
  3. To reduce the risk of vomiting during induction
  4. To speed the onset of intravenous induction agents

Explanation

Preoxygenation raises alveolar and blood oxygen content, extending the time before hemoglobin desaturation during apnea after induction. It does not change MAC or the onset of IV agents and does not prevent vomiting.

Question 10Anesthesia and Analgesia

Which opioid is most commonly used as a constant rate infusion in dogs for intraoperative analgesia because of its rapid onset and titratability?

  1. Fentanyl Correct answer.
  2. Buprenorphine
  3. Methadone
  4. Butorphanol

Explanation

Fentanyl has a very rapid onset and short duration, making it well suited to a titratable constant rate infusion for intraoperative analgesia. Butorphanol and buprenorphine have longer, less titratable profiles, and methadone is typically given as boluses.

Question 11Anesthesia and Analgesia

A dog with a known MDR1 (ABCB1) mutation is being anesthetized. Which class of drug should be avoided because of the risk of severe neurotoxicity?

  1. Isoflurane
  2. Propofol
  3. Ivermectin at high doses Correct answer.
  4. Acepromazine

Explanation

Dogs with ABCB1 mutations have impaired P-glycoprotein efflux and are at risk of severe neurotoxicity from drugs such as high-dose ivermectin and other P-glycoprotein substrates. Isoflurane, propofol, and acepromazine are not classic substrates of concern in this context.

Question 12Anesthesia and Analgesia

Which parameter is the most sensitive indicator of inadequate tissue perfusion during anesthesia?

  1. Mucous membrane color
  2. Lactate concentration Correct answer.
  3. Blood pressure
  4. Heart rate

Explanation

Lactate concentration rises when tissues are poorly perfused and shift to anaerobic metabolism, making it a sensitive marker of perfusion. Mucous membrane color and heart rate can appear normal despite poor perfusion, and blood pressure can be maintained by compensatory vasoconstriction.

Question 13Anesthesia and Analgesia

A dog is anesthetized with isoflurane and becomes bradycardic with a normal arterial blood pressure. Which action is most appropriate?

  1. Increase the isoflurane vaporizer setting
  2. Administer an anticholinergic or reduce the inhalant concentration Correct answer.
  3. Give a bolus of intravenous fluid
  4. Deepen anesthesia

Explanation

Isoflurane causes dose-dependent bradycardia and vasodilation; reducing the inhalant concentration or administering an anticholinergic such as atropine or glycopyrrolate addresses the cause. Deepening anesthesia or increasing the vaporizer setting would worsen the bradycardia.

Question 14Anesthesia and Analgesia

Which statement about the use of atropine in small animal anesthesia is correct?

  1. It produces profound sedation and analgesia
  2. It is contraindicated in all surgical patients
  3. It is used to reverse opioid-induced respiratory depression
  4. It increases heart rate by blocking muscarinic receptors Correct answer.

Explanation

Atropine is a muscarinic antagonist that increases heart rate by blocking vagal effects on the sinoatrial node. It does not provide sedation, analgesia, or opioid reversal. It is not universally contraindicated.

Question 15Anesthesia and Analgesia

A capnograph shows a waveform with a gradual upward slope of the expiratory plateau. What does this most likely indicate?

  1. Cardiac arrest
  2. Hyperventilation
  3. Obstruction of the expiratory limb of the breathing circuit Correct answer.
  4. A leak in the endotracheal tube cuff

Explanation

A gradually rising expiratory plateau (a sloping phase III) suggests uneven alveolar emptying, most commonly caused by obstruction of the expiratory limb or endotracheal tube. A cuff leak causes a loss of the plateau, hyperventilation lowers CO2, and cardiac arrest causes a sudden drop toward zero.

Question 16Anesthesia and Analgesia

Which agent is a dissociative anesthetic that provides analgesia and amnesia but can cause increased muscle tone and rough recovery?

  1. Etomidate
  2. Alfaxalone
  3. Ketamine Correct answer.
  4. Propofol

Explanation

Ketamine is a dissociative anesthetic that produces analgesia and amnesia while preserving some airway reflexes, but it can increase muscle tone and cause rough recoveries. Propofol, alfaxalone, and etomidate are non-dissociative induction agents.

Question 17Anesthesia and Analgesia

Which is the most appropriate initial treatment for a patient with opioid-induced respiratory depression and bradypnea after surgery?

  1. Administer atropine
  2. Increase the inhalant concentration
  3. Administer doxapram
  4. Administer naloxone and provide ventilatory support Correct answer.

Explanation

Opioid-induced respiratory depression is reversed with naloxone, an opioid antagonist, along with supplemental oxygen and ventilatory support. Atropine treats bradycardia, doxapram is a respiratory stimulant that is not first-line, and increasing the inhalant would worsen depression.

Question 18Anesthesia and Analgesia

What is the primary reason for using a cuffed endotracheal tube in a dog undergoing abdominal surgery?

  1. To allow spontaneous breathing only
  2. To measure end-tidal CO2 more accurately than a mask
  3. To prevent aspiration and provide a closed breathing system Correct answer.
  4. To reduce the MAC of the inhalant agent

Explanation

A cuffed endotracheal tube seals the airway, preventing aspiration of gastric contents and allowing a closed or semi-closed breathing system with controlled ventilation. It does not reduce MAC or limit the patient to spontaneous breathing.

Question 19Anesthesia and Analgesia

Which condition is a relative contraindication to the use of acepromazine as a premedication?

  1. A dog with a history of hypotension or shock Correct answer.
  2. A dog with a history of seizure disorder
  3. A dog with mild osteoarthritis
  4. A healthy 2-year-old dog undergoing elective neutering

Explanation

Acepromazine causes vasodilation and hypotension, so it is relatively contraindicated in patients with hypotension or shock. It is generally acceptable in healthy dogs and is not absolutely contraindicated by seizure history or mild osteoarthritis.

Question 20Anesthesia and Analgesia

Which monitoring device directly measures the percentage of hemoglobin saturated with oxygen?

  1. Blood pressure Doppler
  2. Pulse oximeter Correct answer.
  3. Capnograph
  4. Electrocardiogram

Explanation

A pulse oximeter estimates arterial hemoglobin oxygen saturation by measuring light absorption across a pulsatile vascular bed. A capnograph measures CO2, a Doppler measures blood pressure, and an ECG measures electrical cardiac activity.

Question 21Anesthesia and Analgesia

During anesthesia, a dog's end-tidal CO2 rises to 65 mmHg with a stable heart rate and blood pressure. Which action is most appropriate?

  1. Decrease the oxygen flow rate
  2. Administer a fluid bolus
  3. Administer an anticholinergic
  4. Increase the depth of anesthesia or assist ventilation Correct answer.

Explanation

Hypercapnia during anesthesia usually reflects hypoventilation, so assisting ventilation or increasing anesthetic depth to improve respiratory depression control is appropriate. Anticholinergics, fluid boluses, and reducing oxygen flow do not directly address hypoventilation.

Question 22Anesthesia and Analgesia

A cat is given a high dose of an alpha-2 agonist and develops marked bradycardia and pale mucous membranes. Which drug reverses the alpha-2 effects?

  1. Flumazenil
  2. Atipamezole Correct answer.
  3. Yohimbine at a low dose
  4. Naloxone

Explanation

Atipamezole is a selective alpha-2 antagonist used to reverse the sedative and cardiovascular effects of alpha-2 agonists such as dexmedetomidine and medetomidine. Naloxone reverses opioids and flumazenil reverses benzodiazepines.

Question 23Anesthesia and Analgesia

Which statement about the minimum alveolar concentration (MAC) of an inhalant is correct?

  1. MAC is the same for every inhalant agent
  2. MAC is the concentration at which 50% of patients do not respond to a standardized noxious stimulus Correct answer.
  3. MAC is the concentration that produces apnea in all patients
  4. MAC is unaffected by age or body temperature

Explanation

MAC is defined as the alveolar concentration at which 50% of patients do not respond to a standardized noxious stimulus. It varies among agents and is influenced by age, temperature, and other factors.

Question 24Anesthesia and Analgesia

A dog undergoing anesthesia has a sudden onset of ventricular premature complexes. Which electrolyte abnormality is most likely to predispose to this arrhythmia?

  1. Hypernatremia
  2. Hyperkalemia
  3. Hypokalemia Correct answer.
  4. Hypochloremia

Explanation

Hypokalemia predisposes to ventricular arrhythmias and increased myocardial irritability during anesthesia. Hyperkalemia more typically causes bradycardia and conduction abnormalities, while sodium and chloride disturbances are less directly arrhythmogenic.

Question 25Animal Nursing and Patient Care

A veterinary technician is preparing to obtain a blood sample from a dog's cephalic vein. Which restraint approach best facilitates this venipuncture while minimizing patient stress?

  1. Placing the patient in sternal recumbency with the forelimb extended off the table edge and the holder stabilizing the elbow Correct answer.
  2. Restraining the dog in dorsal recumbency and occluding the vein with a tourniquet above the shoulder
  3. Applying a full-body towel wrap and drawing blood from the jugular vein without a holder
  4. Suspending the dog by the forelimbs to engorge the cephalic vein before needle insertion

Explanation

Cephalic venipuncture is best performed with the patient in sternal recumbency, the forelimb extended over the table edge, and an assistant stabilizing the elbow and occluding the vein. This position keeps the limb stable, engorges the vein, and reduces patient movement. Suspending or dorsal restraint increases stress and injury risk without improving access.

Question 26Animal Nursing and Patient Care

Which route is most appropriate for administering a large volume of warmed isotonic crystalloid to a stable, hospitalized dog requiring fluid therapy?

  1. Intraperitoneal injection delivered as a single rapid bolus
  2. Subcutaneous bolus injection into the scruff at multiple sites
  3. Intramuscular injection divided among large muscle groups
  4. Intravenous infusion through an aseptically placed peripheral catheter Correct answer.

Explanation

The intravenous route is preferred for large-volume crystalloid therapy because it allows precise delivery, rapid correction of deficits, and continuous rate control. Subcutaneous administration is limited by absorption rate and volume capacity, while intramuscular and intraperitoneal routes are not appropriate for routine large-volume resuscitation.

Question 27Animal Nursing and Patient Care

A technician is calculating a maintenance fluid rate for a 10 kg dog using the standard formula of 60 mL/kg/day. What is the daily maintenance volume?

  1. 60 mL/day
  2. 1200 mL/day
  3. 600 mL/day Correct answer.
  4. 300 mL/day

Explanation

Multiplying 60 mL/kg/day by 10 kg yields 600 mL per day. This is the typical maintenance estimate for a small dog; the hourly rate would then be 600 divided by 24, or 25 mL/hour. Accurate arithmetic is essential because errors in rate calculation can cause over- or under-hydration.

Question 28Animal Nursing and Patient Care

When placing an indwelling urinary catheter in a male dog, which practice best reduces the risk of catheter-associated urinary tract infection?

  1. Maintaining a closed collection system and performing aseptic site preparation before insertion Correct answer.
  2. Flushing the catheter with tap water every four hours to keep it patent
  3. Leaving the catheter open to drainage onto absorbent pads to avoid stagnation
  4. Disconnecting the collection bag daily to check urine color directly

Explanation

Closed collection systems combined with aseptic insertion and site preparation are the cornerstone of preventing catheter-associated urinary tract infection. Every break in the closed system creates a route for ascending bacterial contamination. Tap water flushing and open drainage both introduce pathogens and should be avoided.

Question 29Animal Nursing and Patient Care

A dog recovering from anesthesia is being monitored in the post-operative period. Which combination of parameters provides the most reliable early indication of inadequate perfusion?

  1. Mucous membrane color, capillary refill time, heart rate, and blood pressure Correct answer.
  2. Respiratory rate and thoracic auscultation alone
  3. Urine specific gravity and packed cell volume measured once daily
  4. Body temperature alone measured every thirty minutes

Explanation

Perfusion is assessed through a combination of mucous membrane color, capillary refill time, heart rate, and blood pressure, which together reflect cardiovascular status. No single parameter reliably detects early hypoperfusion. Temperature, respiration, and laboratory values measured infrequently are insensitive to acute changes.

Question 30Animal Nursing and Patient Care

Which finding on physical examination most strongly suggests dehydration in a canine patient?

  1. Serous ocular discharge and mild epiphora
  2. Bounding femoral pulses and bright pink mucous membranes
  3. Bilateral otitis externa with head shaking
  4. Prolonged skin tent over the dorsal midline and tacky mucous membranes Correct answer.

Explanation

A persistent skin tent and tacky mucous membranes are classic indicators of reduced interstitial and mucosal moisture consistent with dehydration. Bounding pulses and bright membranes suggest adequate or increased perfusion rather than dehydration. Ocular discharge and otitis are unrelated to hydration status.

Question 31Animal Nursing and Patient Care

A technician is preparing to administer a medication via the subcutaneous route to a cat. Which site and technique is most appropriate?

  1. Injecting into the jugular furrow after clipping and aseptic preparation
  2. Tenting the skin over the interscapular region and injecting into the subcutaneous space Correct answer.
  3. Injecting into the caudal thigh muscle at a ninety-degree angle
  4. Injecting into the ventral abdomen at a forty-five-degree angle into muscle

Explanation

The interscapular region provides a large, accessible area of loose subcutaneous tissue well suited to subcutaneous injection in cats. Tenting the skin helps confirm placement in the subcutaneous space. The thigh and ventral abdomen approaches describe intramuscular injection, and the jugular furrow is a venipuncture site.

Question 32Animal Nursing and Patient Care

During a routine wellness examination, a technician notes that the dog has a body condition score of 8 out of 9. What is the most appropriate interpretation and client communication?

  1. The score reflects muscle condition rather than body fat and cannot guide nutrition
  2. The dog is at ideal weight and no intervention is needed
  3. The dog is overweight and the client should be counseled on caloric restriction and weight management Correct answer.
  4. The dog is underweight and requires increased caloric intake

Explanation

A body condition score of 8 out of 9 indicates excess body fat consistent with overweight status. The technician should communicate this finding and discuss portion control, treat reduction, and increased activity. Scores of 4 to 5 out of 9 represent ideal condition, and low scores indicate underweight patients.

Question 33Animal Nursing and Patient Care

Which parameter is most useful for detecting early respiratory compromise in a dyspneic cat before cyanosis develops?

  1. Palpation of the femoral pulse quality
  2. Respiratory rate and effort observed from a distance before handling Correct answer.
  3. Measurement of systolic blood pressure
  4. Auscultation of the heart for murmurs

Explanation

Observing respiratory rate and effort from a distance allows detection of increased work of breathing and tachypnea before oxygenation falls far enough to cause cyanosis. Minimizing handling in dyspneic cats reduces stress-related deterioration. Cardiac auscultation, blood pressure, and pulse palpation assess other systems and do not directly gauge respiratory effort.

Question 34Animal Nursing and Patient Care

A technician is collecting a voided urine sample from a dog for urinalysis. Which handling practice best preserves sample integrity?

  1. Collecting midstream urine into a clean container and refrigerating or analyzing it promptly Correct answer.
  2. Storing the sample in a nonsterile container at body temperature until morning
  3. Diluting the sample with saline to increase volume before submission
  4. Collecting the first portion of the stream and leaving it at room temperature for several hours

Explanation

Midstream collection reduces contamination from the distal urethra and genitalia, and prompt analysis or refrigeration limits bacterial overgrowth and cellular degeneration. Delayed processing at room temperature causes changes in pH, crystal formation, and cell lysis. Dilution and warm storage both invalidate results.

Question 35Animal Nursing and Patient Care

Which action is most appropriate when a technician suspects that a dog has a zoonotic ectoparasite infestation?

  1. Deferring all diagnostic testing until the patient is discharged
  2. Sharing restraint equipment with other patients before disinfection
  3. Handling the patient without gloves to reduce patient stress
  4. Using appropriate personal protective equipment and following practice infection-control protocols Correct answer.

Explanation

Suspected zoonotic ectoparasites require personal protective equipment and adherence to infection-control protocols to protect staff and prevent environmental spread. Gloves, gowns, and equipment disinfection reduce transmission risk. Unprotected handling and shared contaminated equipment increase exposure for personnel and other patients.

Question 36Animal Nursing and Patient Care

A technician is preparing to place an intravenous catheter in a dog. Which step is essential before venipuncture?

  1. Applying a tourniquet and inserting the catheter without skin preparation to save time
  2. Flushing the catheter with heparinized saline before skin preparation
  3. Clipping the site and performing aseptic skin preparation with chlorhexidine or iodine scrub Correct answer.
  4. Coating the catheter with antibiotic ointment before insertion

Explanation

Aseptic skin preparation after clipping is essential before catheter placement to reduce the risk of phlebitis and bloodstream infection. Chlorhexidine or iodine scrub applied with friction and allowed contact time is standard. Skipping preparation, applying ointment, or flushing before preparation does not address skin contamination.

Question 37Animal Nursing and Patient Care

Which nursing intervention is most important for a recumbent, immobilized large-breed dog to prevent pressure sores?

  1. Applying tight bandages over all bony prominences
  2. Restricting fluid intake to reduce urination frequency
  3. Repositioning the patient regularly and providing well-padded bedding Correct answer.
  4. Keeping the patient in one position to reduce pain and movement

Explanation

Frequent repositioning and padded bedding redistribute pressure over bony prominences and maintain circulation to the skin, which prevents decubital ulcers in recumbent patients. Prolonged immobilization in one position promotes ischemia and tissue breakdown. Tight bandages and fluid restriction do not address pressure and can cause harm.

Question 38Animal Nursing and Patient Care

A technician is asked to obtain a blood pressure reading on an anxious cat. Which technique improves measurement reliability?

  1. Using a cuff that covers most of the limb regardless of circumference
  2. Taking a single reading immediately after physical restraint
  3. Allowing the cat to acclimate in a quiet room and using the appropriately sized cuff on the limb or tail Correct answer.
  4. Measuring only while the cat is vocalizing to confirm the pulse

Explanation

Accurate blood pressure measurement requires a calm patient, an appropriately sized cuff, and a consistent technique, ideally averaging multiple readings. An undersized or oversized cuff distorts readings, and immediate restraint elevates values through stress. Multiple measurements in a quiet setting improve reliability.

Question 39Animal Nursing and Patient Care

Which observation most reliably indicates that a patient has adequate oxygenation during recovery from anesthesia?

  1. Absence of a gag reflex and flaccid jaw tone
  2. A heart rate above one hundred beats per minute
  3. Presence of shivering and piloerection
  4. Pink mucous membranes with a capillary refill time under two seconds and normal respiratory pattern Correct answer.

Explanation

Pink mucous membranes, brisk capillary refill, and a regular respiratory pattern together suggest adequate perfusion and oxygenation. Absence of gag reflex and flaccid jaw tone indicate residual anesthetic depth, not oxygenation. Heart rate and shivering reflect other physiologic processes and are not direct indicators of oxygenation.

Question 40Animal Nursing and Patient Care

A technician is preparing a patient for surgery and must perform a surgical skin scrub. Which principle governs the direction of scrubbing?

  1. Scrub from the incision site outward in a circular motion, moving away from the center Correct answer.
  2. Scrub from the periphery toward the incision site to concentrate antiseptic at the center
  3. Scrub in a back-and-forth pattern across the entire field without regard to direction
  4. Scrub only the hair coat without contacting the skin surface

Explanation

Surgical skin preparation begins at the intended incision site and moves outward in concentric circles so that contamination from the periphery is not carried back to the center. Scrubbing toward the center would drag organisms into the surgical field. Directional technique and adequate contact time are essential for antisepsis.

Question 41Animal Nursing and Patient Care

Which sign in a hospitalized cat most warrants immediate notification of the veterinarian?

  1. Sudden onset of open-mouth breathing with increased respiratory effort Correct answer.
  2. A single episode of grooming after eating
  3. Purring during gentle handling
  4. Voluntary urination in the litter box

Explanation

Open-mouth breathing in cats is an abnormal and often urgent sign of severe respiratory distress, and it requires immediate veterinary assessment. Cats typically breathe only through their noses, so open-mouth breathing signals significant compromise. Grooming, normal urination, and purring reflect normal or relaxed behavior.

Question 42Animal Nursing and Patient Care

When performing a physical examination on a dog, which sequence best supports a thorough and low-stress evaluation?

  1. Examine only the system the owner identified as the problem
  2. Observe from a distance, then perform hands-on examination from head to tail while reserving painful areas for last Correct answer.
  3. Begin with the most painful area to assess severity immediately
  4. Perform auscultation only after completing all other manipulations

Explanation

A systematic head-to-tail examination after initial distant observation ensures all body systems are assessed while minimizing stress and pain. Reserving painful areas for last prevents guarding from interfering with the rest of the examination. Focusing only on one complaint risks missing concurrent abnormalities.

Question 43Animal Nursing and Patient Care

A technician must administer oral medication to a fractious cat. Which approach best balances safety and efficacy?

  1. Using a pill popper or syringe after gentle restraint, or a low-stress handling technique such as a towel wrap Correct answer.
  2. Restraining the cat in dorsal recumbency without assistance and administering the pill
  3. Mixing the medication into the entire water bowl without confirming intake
  4. Forcing the mouth open with fingers and placing the pill directly on the tongue

Explanation

Low-stress handling techniques such as towel wraps or a pill popper reduce the risk of bites and improve medication delivery. Placing fingers in the mouth of a fractious cat risks injury, and dorsal restraint without assistance is unsafe. Mixing medication into a water bowl does not ensure the patient receives the full dose.

Question 44Animal Nursing and Patient Care

A dog is receiving a constant rate infusion of a drug through an infusion pump. Which action is most important to ensure accurate delivery?

  1. Relying on gravity flow without checking the pump settings
  2. Disconnecting the line during repositioning without occluding the catheter
  3. Increasing the rate to compensate for a suspected delay in reaching the patient
  4. Verifying the pump programming against the prescribed rate and checking the line for patency Correct answer.

Explanation

Accurate constant rate infusion delivery requires verifying the programmed rate against the prescription and confirming line patency and catheter security. Adjusting the rate without authorization can cause overdose, and disconnecting the line without occlusion risks air entry or blood loss. Gravity flow is not a substitute for pump verification.

Question 45Animal Nursing and Patient Care

Which technique is most appropriate for cleaning the ears of a dog with excessive cerumen but no evidence of tympanic membrane rupture?

  1. Instilling hydrogen peroxide repeatedly until the canal appears clear
  2. Flushing the ear canal with high-pressure water from a syringe directed at the tympanum
  3. Inserting a cotton swab deep into the horizontal ear canal to remove debris
  4. Applying a veterinary-approved ceruminolytic cleaner and gently massaging the ear canal base before allowing the dog to shake Correct answer.

Explanation

Ceruminolytic cleaners soften debris, and gentle massage at the base of the ear canal helps distribute the product before the dog shakes out loosened material. Deep cotton swab insertion risks trauma and impaction, high-pressure flushing can damage the tympanum, and repeated hydrogen peroxide can irritate the canal.

Question 46Animal Nursing and Patient Care

A technician is assessing pain in a post-operative dog. Which combination of findings most reliably indicates significant pain requiring intervention?

  1. Interest in food and interaction with staff
  2. Reluctance to move, guarding of the surgical site, and increased heart rate and respiratory rate Correct answer.
  3. A single yawn followed by stretching
  4. Resting quietly with a relaxed body posture and slow breathing

Explanation

Pain assessment in dogs relies on combined behavioral and physiologic signs, including guarding, reluctance to move, and elevated heart and respiratory rates. Quiet resting, interest in food, and normal interaction suggest comfort. A single yawn or stretch does not indicate pain and is a normal behavior.

Question 47Animal Nursing and Patient Care

A technician is calculating a drug dose for a 15 kg dog where the prescribed dose is 5 mg/kg and the drug concentration is 10 mg/mL. What volume should be administered?

  1. 1.5 mL
  2. 7.5 mL Correct answer.
  3. 0.75 mL
  4. 75 mL

Explanation

The total dose is 15 kg multiplied by 5 mg/kg, which equals 75 mg. Dividing 75 mg by the concentration of 10 mg/mL yields 7.5 mL. Checking the arithmetic and units before administration is a critical safety step in veterinary nursing.

Question 48Animal Nursing and Patient Care

During a blood transfusion in a dog, the technician observes a sudden rise in temperature, tachycardia, and restlessness. What is the most appropriate immediate action?

  1. Administer an antihistamine and continue the transfusion at the same rate
  2. Slow the transfusion rate and continue monitoring without notifying the veterinarian
  3. Increase the transfusion rate to finish the unit more quickly
  4. Stop the transfusion, maintain intravenous access with a crystalloid, and notify the veterinarian immediately Correct answer.

Explanation

Acute transfusion reactions can present with fever, tachycardia, and restlessness, and the first action is to stop the transfusion while maintaining vascular access and contacting the veterinarian. Continuing or accelerating the transfusion risks worsening the reaction. Treatment decisions follow veterinary assessment of the reaction type.

Question 49Animal Nursing and Patient Care

A technician is evaluating a dog with suspected hypovolemic shock. Which set of findings best supports this assessment?

  1. Normal heart rate with strong pulses and warm extremities
  2. Serous nasal discharge with a normal capillary refill time
  3. Bright pink mucous membranes, bradycardia, and bounding pulses
  4. Pale mucous membranes, prolonged capillary refill time, tachycardia, and weak pulses Correct answer.

Explanation

Hypovolemic shock produces poor perfusion characterized by pale mucous membranes, prolonged capillary refill, compensatory tachycardia, and weak pulses. Bright pink membranes with bounding pulses suggest adequate or increased perfusion, and normal findings do not support shock. Nasal discharge is unrelated to volume status.

Question 50Animal Nursing and Patient Care

A technician is preparing to express the anal sacs of a healthy medium-breed dog during a routine visit. Which anatomical landmark guides correct placement of the externally applied thumb and forefinger?

  1. The ischiorectal fossa deep to the greater trochanter
  2. The ventral midline just cranial to the prepuce
  3. The lateral margins of the anus at approximately the 4 and 8 o'clock positions Correct answer.
  4. The dorsal aspect of the tail base at the 12 o'clock position

Explanation

The anal sacs lie ventrolateral to the anus, and external expression is performed by positioning the thumb and forefinger at roughly the 4 and 8 o'clock positions and pressing inward and together. This compresses the sacs against the anal canal wall and expresses their contents through the ducts. Palpating elsewhere on the perineum or tail base will not empty the sacs and may cause discomfort without benefit.
