Correct answer: Maintaining a warm but professional demeanor during all interactions

Professional boundaries include keeping interactions warm yet appropriate, avoiding personal entanglements that could compromise objectivity.

Question 4: Which drug is used to reverse the sedative and analgesic effects of medetomidine or dexmedetomidine in dogs?

Neostigmine
Naloxone
Atipamezole (Correct answer)
Flumazenil

Correct answer: Atipamezole

Atipamezole (Antisedan) is a selective alpha-2 adrenergic antagonist that rapidly reverses the effects of medetomidine and dexmedetomidine.

Question 5: Which technique is most appropriate for performing a blood draw from the jugular vein of a cat?

Sternal recumbency with the head turned to the side
Standing position with the scruff held tightly
Lateral recumbency with the forelimbs extended over the table edge (Correct answer)
Dorsal recumbency with the neck hyperextended

Correct answer: Lateral recumbency with the forelimbs extended over the table edge

Lateral recumbency with forelimbs extended over the table edge exposes the jugular vein while maintaining safe, controlled restraint.

Question 6: The root word 'hepat/o' refers to which organ?

Spleen
Pancreas
Kidney
Liver (Correct answer)

Correct answer: Liver

Hepat/o is the combining form for the liver, as seen in hepatitis (liver inflammation).

Question 7: A client is non-compliant and has not been giving their pet the prescribed medication. The ethical approach is to:

Document the non-compliance and refuse future care
Report the client to animal control immediately
Non-judgmentally explore barriers to compliance and offer solutions (Correct answer)
Scold the client for neglecting their pet

Correct answer: Non-judgmentally explore barriers to compliance and offer solutions

Non-judgmental exploration of barriers (cost, difficulty, misunderstanding) helps identify solutions and improve compliance.

Question 8: When performing a blood smear using the push-slide technique, what does a smear that is too thick most likely indicate?

The spreader slide angle was too low (less than 30°)
The blood sample was too old
The spreader slide was pushed too slowly
The spreader slide angle was too high (greater than 45°) or a large drop of blood was used (Correct answer)

Correct answer: The spreader slide angle was too high (greater than 45°) or a large drop of blood was used

A steep angle or too large a blood drop produces a thick smear where cells overlap, making differential counting unreliable.

Question 9: A new floor cleaning agent is introduced in the clinic. To comply with OSHA regulations, where would a veterinary assistant find detailed information about the chemical's potential hazards, required personal protective equipment (PPE), and first-aid measures?

On the chemical's Safety Data Sheet (SDS). (Correct answer)

Question 14: What is the function of a veterinary nurse in pain management?

Giving injections without assessing pain.
Assessing pain and providing pain relief treatments. (Correct answer)
Only observing the animal's behavior.
Recommending surgical procedures.

Correct answer: Assessing pain and providing pain relief treatments.

Veterinary nurses are skilled in assessing pain in animals, recognizing subtle behavioral and physiological signs of discomfort. Based on their assessment and the veterinarian's orders, they administer appropriate pain relief treatments, such as medications or supportive therapies. Their proactive approach to pain management is crucial for improving animal welfare, promoting faster recovery, and ensuring comfort during illness or post-surgery.

Question 15: A client presents with a pet that is not registered in the practice management software. The FIRST step is to:

Ask the veterinarian to handle the intake without creating a file
Turn the client away until they have a scheduled appointment
Create a new client and patient record before proceeding with the visit (Correct answer)
Use another client's record temporarily to save time

Correct answer: Create a new client and patient record before proceeding with the visit

Accurate record creation for every patient is required before any clinical or billing activities can proceed.

Question 16: What does 'PRN' mean on a veterinary prescription label?

Twice daily
By mouth
As needed (Correct answer)
Every night

Correct answer: As needed

PRN is an abbreviation from Latin 'pro re nata,' meaning 'as needed' or 'as the situation demands.'

Question 17: Which laboratory value is most useful for evaluating hepatic (liver) function in dogs and cats?

Amylase
Alanine aminotransferase (ALT) (Correct answer)
Creatinine
Blood urea nitrogen (BUN)

Correct answer: Alanine aminotransferase (ALT)

ALT is a liver-specific enzyme in dogs and cats; elevations indicate hepatocellular damage, making it the primary marker for hepatic disease.

Question 18: How long can a whole blood sample in an EDTA tube typically be stored at room temperature before CBC results become unreliable?

Up to 4 hours (Correct answer)
Up to 72 hours
Indefinitely if sealed
Up to 24 hours

Question 22: Which route of drug administration provides the fastest onset of action in an emergency?

Intravenous (Correct answer)
Oral
Intramuscular
Subcutaneous

Correct answer: Intravenous

Intravenous administration delivers drugs directly into the bloodstream, producing the fastest onset of action.

Question 23: What is the correct method for preparing a blood smear for differential WBC count?

Place a large drop and cover with a coverslip
Place a small drop near one end, use a spreader slide at 30-45 degrees to push forward in one smooth motion (Correct answer)
Spin blood in a centrifuge and examine the buffy coat
Dip the slide directly into the blood tube

Correct answer: Place a small drop near one end, use a spreader slide at 30-45 degrees to push forward in one smooth motion

A proper wedge smear uses a small drop and a spreader slide at 30-45 degrees, creating a feathered edge where cells are in a monolayer.

Question 24: Which of the following best describes the purpose of a day sheet (daily journal) in veterinary practice management?

It tracks all financial transactions for the day including charges and payments (Correct answer)
It documents controlled substance dispensing only
It records employee vacation schedules
It lists upcoming appointments for the next business day

Correct answer: It tracks all financial transactions for the day including charges and payments

The day sheet is a chronological record of all daily financial transactions used for balancing accounts at day's end.

Question 25: What is the proper handling of a blood smear immediately after spreading it on a slide?

Cover it with a coverslip right away
Immediately place it in fixative while still wet
Refrigerate it before staining
Allow it to air dry completely before staining (Correct answer)

Blood smears must air dry completely before staining to ensure proper cell morphology and prevent cell distortion.

Question 26: When placing an intravenous catheter in an emergency patient, which vein is MOST commonly used as the first choice in dogs?

Jugular vein
Auricular vein
Saphenous vein
Cephalic vein (Correct answer)

Correct answer: Cephalic vein

The cephalic vein (running along the cranial foreleg) is the most accessible and commonly used first-choice IV site in dogs. It is easy to visualize, restrain, and catheterize. The jugular vein is reserved for rapid volume delivery, central venous pressure monitoring, or when peripheral access fails. The saphenous vein is a secondary peripheral option, and the auricular vein is used in rabbits.

Question 27: A veterinary assistant notices the eyewash station has not been flushed this week. What is the correct action?

Wait until it is needed before flushing
Replace the entire eyewash unit as it is contaminated
Flush the eyewash station immediately for at least 5 minutes to clear stagnant water (Correct answer)
Log the finding and notify the next shift

Eyewash stations should be flushed weekly for at least 5 minutes to prevent microbial growth in stagnant water and ensure readiness in an emergency.

Question 28: A veterinary assistant is preparing the skin of a cat for an abdominal surgery. Which of the following describes the correct pattern for the final sterile scrub?

Beginning at the periphery of the clipped area and moving inward.
Using a circular motion, starting at the proposed incision site and moving outward. (Correct answer)
Scrubbing in a back-and-forth motion across the entire clipped area.
Applying the scrub solution and letting it air dry completely without rinsing.

Correct answer: Using a circular motion, starting at the proposed incision site and moving outward.

The correct aseptic technique for a surgical scrub is to start at the center of the surgical site (where the incision will be made) and move in an ever-widening circle outward. This pattern prevents dragging contaminants from the less clean peripheral areas back over the prepared incision site. You should never go back to the center with the same piece of gauze.

Question 29: Why is providing supportive care important for recovering animals?

It prevents future illnesses.
It helps speed up recovery and reduces the risk of complications. (Correct answer)
It allows for faster discharge from the clinic.
It helps with administrative duties.

Correct answer: It helps speed up recovery and reduces the risk of complications.

Providing supportive care is vital for recovering animals because it significantly speeds up their healing process and reduces the risk of complications. This comprehensive care includes pain management, nutritional support, wound care, and maintaining a comfortable environment. By addressing these needs, veterinary staff help the animal recover more quickly and prevent setbacks.

Question 30: What term describes the ability of a drug to produce a harmful or toxic effect on a developing fetus?

Carcinogenic
Mutagenic
Nephrotoxic
Teratogenic (Correct answer)

Correct answer: Teratogenic

Correct answer: Maropitant (Cerenia)

Maropitant is an NK1 receptor antagonist that blocks substance P at the emetic center, making it the most effective broad-spectrum veterinary antiemetic.

Question 32: Which piece of restraint equipment is most appropriate for handling an extremely aggressive dog that cannot be safely approached?

An Elizabethan collar
A towel
A slip lead
A control pole (catch pole) (Correct answer)

Correct answer: A control pole (catch pole)

A control pole, also known as a catch pole or rabies pole, is designed to handle extremely aggressive or feral dogs from a safe distance, preventing bites. A slip lead requires close contact, and a towel would not offer sufficient protection from a truly aggressive dog. An Elizabethan collar is used to prevent self-trauma, not for initial restraint of an aggressive animal.

Question 33: Which term describes an unexpected or unusual adverse drug reaction not related to the drug's pharmacological action?

Tolerance
Idiosyncratic reaction (Correct answer)
Synergism
Tachyphylaxis

Correct answer: Idiosyncratic reaction

An idiosyncratic reaction is an unpredictable, abnormal response to a drug that is not dose-dependent and not related to its primary mechanism.

Question 34: What is the primary purpose of using a loading dose when starting a drug therapy?

To reduce side effects
To test for allergic reactions
To extend the drug's half-life
To quickly achieve therapeutic drug levels (Correct answer)

Correct answer: To quickly achieve therapeutic drug levels

A loading dose is a larger initial dose given to rapidly achieve therapeutic plasma concentrations before maintenance dosing begins.

Question 35: What ethical obligation does a veterinary assistant have when they witness a colleague behaving unethically?

Handle the matter by confronting the colleague publicly
Stay silent to avoid conflict
Report the behavior to a supervisor or appropriate authority (Correct answer)
Join the colleague's behavior to maintain team unity

Ethical obligations require reporting witnessed unethical behavior through appropriate channels to protect patients and maintain professional standards.

Question 36: Atropine is classified as which type of drug?

Anticholinergic (Correct answer)
Opioid analgesic
Beta-blocker
Alpha-agonist

Correct answer: Anticholinergic

Atropine is an anticholinergic (antimuscarinic) agent that blocks acetylcholine receptors, commonly used as a preanesthetic.

Question 37: What is the function of the circulatory system in animals?

Transporting food.
Helping with digestion.
Regulating temperature.
Transporting oxygen, nutrients, and waste. (Correct answer)

Correct answer: Transporting oxygen, nutrients, and waste.

The circulatory system in animals is vital for transporting essential substances throughout the body. Its primary function is to deliver oxygen and nutrients to cells while simultaneously collecting and transporting metabolic waste products for elimination, ensuring proper cellular function and overall health.

Question 38: What does lipemia mean when noted on a blood sample?

High white blood cell count from infection
Cloudiness of serum due to elevated triglycerides, usually from a non-fasted sample (Correct answer)
Yellow discoloration from elevated bilirubin
Red discoloration from hemolysis

Correct answer: Cloudiness of serum due to elevated triglycerides, usually from a non-fasted sample

Lipemia refers to turbidity caused by elevated triglycerides and lipoproteins, most commonly from blood drawn from a non-fasted patient.

Question 39: When a drug label states 'SID,' how often should the medication be administered?

Twice daily
Three times daily
Once daily (Correct answer)
Every other day

Correct answer: Once daily

SID stands for 'semel in die,' Latin for 'once a day,' indicating once-daily dosing.

Question 40: What does the suffix '-ectomy' mean?

Surgical creation of an opening
Inflammation of
Surgical repair
Surgical removal or excision (Correct answer)

Correct answer: Surgical removal or excision

'-ectomy' means surgical removal. For example, splenectomy is removal of the spleen, ovariohysterectomy is removal of ovaries and uterus.

Question 41: A vaginal cytology smear from a dog showing predominantly cornified (anuclear) squamous epithelial cells indicates:

Estrus (standing heat) (Correct answer)
Diestrus
Anestrus
Proestrus

Correct answer: Estrus (standing heat)

Cornified anuclear squamous cells predominate during estrus due to peak estrogen stimulation of the vaginal epithelium.

Question 42: Why must patients undergoing veterinary dental procedures always be under general anesthesia, rather than sedation alone?

Anesthesia is only required for tooth extractions, not routine cleanings
Dental instruments require general anesthesia to function correctly
Sedation is equally acceptable as long as the patient is calm
A cuffed endotracheal tube protects the airway from water and debris aspiration during the procedure (Correct answer)

Correct answer: A cuffed endotracheal tube protects the airway from water and debris aspiration during the procedure

General anesthesia with a cuffed endotracheal tube is mandatory because dental procedures generate water spray, calculus fragments, and bacteria-laden aerosols that could be inhaled into the lungs (aspiration pneumonia). Anesthesia also allows thorough subgingival cleaning and radiographs that are impossible in an awake or lightly sedated patient. AVDC and AAHA guidelines explicitly prohibit 'anesthesia-free' dental cleanings.

Question 43: A post-surgical incision appears red, swollen, with yellowish discharge. What should you do?

Sutures are dissolving normally
It is just seroma fluid that will resolve
Document signs of possible surgical site infection and report to the veterinarian (Correct answer)
Normal healing, no action needed

Correct answer: Document signs of possible surgical site infection and report to the veterinarian

Redness, swelling, and purulent discharge are cardinal signs of infection that must be documented and reported.

Question 44: Why must oral suspension medications be shaken thoroughly before dispensing?

To activate the chemical compounds
To remove air bubbles
To warm the medication
To ensure uniform distribution of active ingredient for accurate dosing (Correct answer)

Correct answer: To ensure uniform distribution of active ingredient for accurate dosing

Insoluble drug particles settle over time. Shaking resuspends them evenly so each dose contains the correct amount.

Question 45: What is the correct order for cleaning and disinfecting a surgical suite between procedures?

Sweep the floor and wipe with alcohol
Apply disinfectant, clean with detergent, air dry
Remove organic matter, clean with detergent, rinse, apply disinfectant (Correct answer)
Disinfect, then remove organic matter, then rinse

Correct answer: Remove organic matter, clean with detergent, rinse, apply disinfectant

Organic matter must be removed first because it inactivates most disinfectants. The sequence is: remove debris, detergent clean, rinse, then disinfect.

Question 46: A CVA dilutes a concentrated disinfectant into a spray bottle for use in the exam rooms. According to OSHA's Hazard Communication Standard, which of the following is the MOST critical information to include on the new spray bottle's label?

The date the solution was mixed.
The identity of the chemical and its specific hazards. (Correct answer)
The initials of the person who made the solution.
The phone number for the poison control center.

Correct answer: The identity of the chemical and its specific hazards.

OSHA's Hazard Communication Standard requires that all secondary containers be properly labeled to ensure employee safety. The label must, at a minimum, identify the hazardous chemical inside and provide information about its specific hazards (e.g., flammable, corrosive). [21, 23]

Question 47: A client is upset about a long wait time. The most professional way to address this is to:

Ignore the complaint and continue working
Blame the veterinarian for the delay
Apologize and provide an estimated wait time update (Correct answer)
Ask the client to reschedule

Correct answer: Apologize and provide an estimated wait time update

Acknowledging the inconvenience and providing a realistic update shows empathy and maintains client trust.

Question 48: A veterinary assistant is packaging a blood sample to be shipped to a diagnostic laboratory. According to standard guidelines, what constitutes the 'triple packaging' system?

A styrofoam cooler, bubble wrap, and a sealed plastic container.
The blood tube, a padded envelope, and a biohazard bag.
A leak-proof primary container, a leak-proof secondary container with absorbent material, and a rigid outer box. (Correct answer)

Correct answer: A leak-proof primary container, a leak-proof secondary container with absorbent material, and a rigid outer box.

Shipping regulations for biological specimens require a triple packaging system to prevent leaks and ensure safety. This consists of: 1) a securely sealed, leak-proof primary container (the blood tube itself), 2) a leak-proof secondary container (like a sealed bag or jar) with enough absorbent material to contain any potential spill, and 3) a durable, rigid outer package for transport.

Question 49: Metronidazole is most commonly used in veterinary medicine to treat which type of infection?

Viral infections
Ectoparasite infestations
Fungal infections
Anaerobic bacterial and protozoal infections (Correct answer)

Correct answer: Anaerobic bacterial and protozoal infections

Metronidazole is effective against anaerobic bacteria and protozoa such as Giardia and Trichomonas.

Question 50: What does the acronym SOAP stand for in the context of a veterinary medical record?

Subjective, Objective, Assessment, Plan (Correct answer)
Symptoms, Observations, Analysis, Procedure
Subjective, Objective, Analysis, Prognosis
Surgery, Observations, Assessment, Plan

Correct answer: Subjective, Objective, Assessment, Plan

SOAP is a structured medical record format: Subjective (history/complaints), Objective (physical findings), Assessment (diagnosis), and Plan (treatment).

Question 51: Which anticoagulant tube is used when collecting blood for a complete blood count (CBC)?

Green top (heparin)
Purple/lavender top (EDTA) (Correct answer)
Blue top (sodium citrate)
Red top (no additive)

Correct answer: Purple/lavender top (EDTA)

EDTA (purple/lavender top) is the anticoagulant of choice for CBC because it best preserves cell morphology and prevents clotting without affecting cell counts.

Question 52: For a rabbit that begins to kick violently during restraint, the most dangerous consequence to the rabbit is:

Fractured vertebrae from spinal twisting (Correct answer)
Bite wounds to the handler
Skin tears from struggling
Respiratory distress from stress

Correct answer: Fractured vertebrae from spinal twisting

Rabbits can fracture their own lumbar vertebrae when they kick powerfully during improper restraint due to their powerful hindlimbs and fragile spine.

Question 53: When a client uses technical jargon incorrectly about their pet's condition, you should:

Agree with their terminology to avoid conflict
Ignore it since they are not professionals
Gently clarify the correct term without making them feel embarrassed (Correct answer)
Correct them bluntly to prevent miscommunication

Correct answer: Gently clarify the correct term without making them feel embarrassed

Gently clarifying medical terminology helps ensure accurate communication while preserving the client's dignity.

Question 54: What does 'contraindication' mean in veterinary pharmacology?

A recommended drug combination
A condition or factor that makes a drug unsafe to use (Correct answer)
An alternative dosing schedule
A drug interaction that increases efficacy

Correct answer: A condition or factor that makes a drug unsafe to use

A contraindication is a specific situation or condition in which a drug should not be used because its risks outweigh the benefits.

Question 55: Which is the most appropriate way to greet a client upon arrival at the practice?

Shout a greeting from across the room
Only greet clients you recognize
Make eye contact, smile, and acknowledge them promptly (Correct answer)
Ignore them until they approach the desk

Correct answer: Make eye contact, smile, and acknowledge them promptly

A prompt, friendly acknowledgment sets a positive tone for the visit and makes clients feel welcomed.

Looking at the computer screen while the client speaks
Interrupting to offer a diagnosis quickly
Nodding, maintaining eye contact, and paraphrasing what the client said (Correct answer)
Asking only yes-or-no questions

Correct answer: Nodding, maintaining eye contact, and paraphrasing what the client said

Active listening involves giving full attention, acknowledging the speaker, and reflecting content back to ensure understanding.

Question 57: Which of the following is the most critical piece of information to include when labeling a urine sample collected via cystocentesis that will be sent to an external lab for culture?

The patient's name, owner's name, and collection method. (Correct answer)
The patient's current medications.
The volume of urine collected.
The time of day the sample was collected.

Correct answer: The patient's name, owner's name, and collection method.

While all details are helpful, the patient's name and owner's name are essential for positive identification. Indicating the collection method (cystocentesis) is critical for interpreting culture results, as it is the most sterile method and helps the lab differentiate between true infection and contamination.

Question 58: A veterinarian writes a prescription for an anti-anxiety medication to be given "PRN for thunderstorms." How should the CVA explain these instructions to the pet owner?

Give the medication by mouth thirty minutes before every meal.
Give the medication once a day, every day, during thunderstorm season.
Give the medication as needed specifically when there are thunderstorms. (Correct answer)
Give the medication every 12 hours on days when storms are forecast.

Correct answer: Give the medication as needed specifically when there are thunderstorms.

The Latin abbreviation 'PRN' stands for 'pro re nata,' which translates to 'as the occasion arises' or 'as needed'. In this context, it means the medication should only be administered when the specific trigger (thunderstorms) is present.

Question 59: A 44-pound dog needs a medication that is dosed at 2 mg/kg. The medication is available in a 10 mg/mL liquid concentration. How many milliliters should be administered per dose? (1 kg = 2.2 lbs)

8.8 mL
2.0 mL
4.0 mL (Correct answer)
2.2 mL

Correct answer: 4.0 mL

First, convert the dog's weight from pounds to kilograms: 44 lbs / 2.2 lbs/kg = 20 kg. Next, calculate the total dose in milligrams: 20 kg * 2 mg/kg = 40 mg. Finally, determine the volume in milliliters: 40 mg / 10 mg/mL = 4.0 mL.

Question 60: What does hemolysis in a blood sample indicate and how does it affect results?

Correct collection with more accurate results
Red blood cells have ruptured, causing false elevations in potassium, AST, and LDH (Correct answer)
Elevated white blood cells requiring sample discard
Bacterial infection with no effect on results

Correct answer: Red blood cells have ruptured, causing false elevations in potassium, AST, and LDH

Hemolysis occurs when RBCs rupture, releasing intracellular contents that falsely elevate potassium, AST, LDH, and phosphorus.

Question 61: A CVA is comforting a client in an exam room just before a scheduled euthanasia. The client asks, "Are you sure this is the right thing to do? Is there anything else we can try?" What is the CVA's most appropriate response?

"Yes, this is definitely the kindest option. Your pet is suffering a lot."
"I'm not qualified to give a medical opinion, but I can see how difficult this is for you. Let me get the veterinarian to come speak with you right away." (Correct answer)
"The doctor has already reviewed the case and this is the only choice left."
"You could look into some holistic therapies, but they are very expensive."

Correct answer: "I'm not qualified to give a medical opinion, but I can see how difficult this is for you. Let me get the veterinarian to come speak with you right away."

A CVA must not offer a medical prognosis or opinion on the treatment plan, as this is outside their scope of practice. The most ethical and compassionate response is to show empathy and immediately involve the veterinarian, who is the only one qualified to discuss the prognosis and confirm the decision with the client.

Question 62: Which restraint device is most appropriate for a rabbit that needs abdominal radiographs?

Standard dog leash
Plexiglass restraint box or V-trough (Correct answer)
Elizabethan collar
Cat muzzle

Correct answer: Plexiglass restraint box or V-trough

A plexiglass restraint box or V-trough supports the rabbit's body, prevents movement, and allows radiographic exposure without handler involvement in the beam.

Question 63: Which disinfectant is considered effective against parvovirus on hard surfaces?

Chlorhexidine gluconate 2%
Dilute bleach (sodium hypochlorite 1:32) (Correct answer)
Quaternary ammonium compounds
Isopropyl alcohol 70%

Correct answer: Dilute bleach (sodium hypochlorite 1:32)

Parvovirus is a non-enveloped virus resistant to many disinfectants, but dilute bleach (1:32 dilution of household bleach) is effective against it on hard, non-porous surfaces.

Question 64: What type of needle is preferred for suturing skin in veterinary patients?

Round-body needle
Taper-point needle
Blunt-point needle
Reverse cutting needle (Correct answer)

Correct answer: Reverse cutting needle

Reverse cutting needles have the cutting edge on the outer curve, making them ideal for tough tissues like skin because they resist cutting through the suture line.

Question 65: A body condition score (BCS) of 5 out of 9 in a dog indicates:

Severely obese
Underweight
Ideal body weight (Correct answer)
Obese

Correct answer: Ideal body weight

On the 9-point BCS scale, a score of 5 represents ideal body condition with ribs easily palpable and a visible waist.

Question 66: A CVA is asked to assist with restraining a healthy but nervous rabbit for a nail trim. What is the MOST critical aspect of handling to prevent injury to the rabbit?

Wearing leather gloves to protect from scratches.
Placing the rabbit on a cold, metal surface to calm it.
Holding it tightly by the scruff to prevent movement.
Supporting its hind legs and back at all times. (Correct answer)

Correct answer: Supporting its hind legs and back at all times.

Rabbits have a delicate skeletal structure and powerful hind legs. If they kick out while not properly supported, they can easily fracture their own spine. Therefore, the most critical safety measure is to always support the rabbit's back and hindquarters to prevent this type of injury.

Question 67: When using an in-house chemistry analyzer, a hemolyzed sample may falsely affect which value?

Potassium (K+), causing a falsely elevated result (Correct answer)
Sodium, causing a decreased result
Glucose, causing no interference
BUN, causing a falsely decreased result

Correct answer: Potassium (K+), causing a falsely elevated result

Red blood cells contain high concentrations of potassium; hemolysis releases intracellular K+ into the sample, falsely elevating the measured potassium level.

Question 68: What does a refractometer measure with urine, and what is normal for dogs?

Glucose concentration, normal 0 mg/dL
Urine specific gravity (concentration), normal 1.015-1.045 (Correct answer)
Urine pH, normal 6.0-7.0
