NAVTA AVA common mistakes
NAVTA AVA · Understand the traps and how to avoid them.
On a limb, the candidate labels a structure near the paw as 'caudal' rather than 'distal,' or says the elbow is 'distal to the carpus.'
They memorize cranial/caudal, dorsal/ventral, and proximal/distal as one vocabulary list without mapping each pair to a body region, so the terms blur under exam pressure.
What to do instead
Drill the rule that proximal/distal apply to limbs and their appendages, while cranial/caudal apply to the trunk and head. Practice labeling a limb diagram from shoulder to paw and state the reference point out loud before choosing a term.
The candidate reverses left/right abbreviations, writing 'OS' for the right eye or 'AD' for the left ear.
OD/OS and AD/AS look nearly identical, and candidates memorize them as paired letter strings instead of linking each letter to an anatomical word.
What to do instead
Anchor the terms: O = oculus (eye), A = auris (ear); D = dexter (right), S = sinister (left). Build a two-column table and quiz yourself by covering either the abbreviation or the meaning, not both at once.
The candidate places a muzzle on a dog that is vomiting, coughing, or showing increased respiratory effort because it is fractious.
They default to 'muzzle every aggressive dog' without considering airway compromise, aspiration risk, or brachycephalic anatomy.
What to do instead
Treat vomiting, respiratory distress, and brachycephalic conformation as muzzle contraindications. Use a towel, a trained second handler, or veterinarian-directed chemical restraint, and document the reason restraint was modified.
The candidate lifts a cat off the table by the scruff so the front limbs dangle while attempting jugular venipuncture.
Scruffing is taught as a fast cat-handling shortcut, and full suspension appears to control the head and neck.
What to do instead
Use a low-stress, four-point hold with the cat's feet supported, or a towel wrap. Reserve minimal scruffing for brief procedures, never suspend the cat, and avoid scruffing obese or dyspneic cats.
During surgical skin preparation, the candidate scrubs from the incision line outward to the periphery, then palpates the prepped center with bare fingers.
They transfer household cleaning habits, where scrubbing outward from a dirty center seems logical, and underestimate how quickly a gloved or bare hand contaminates the site.
What to do instead
Scrub in concentric circles from the intended incision outward, never returning a used swab to the center. After prep, handle the site only with sterile gloves or instruments and keep the prepped field covered until surgery.
The candidate counts respirations for a few seconds and multiplies, or records only the number without noting respiratory effort or character.
Time pressure during appointments encourages shortcut counting, and candidates treat respiratory rate as a number-only vital sign.
What to do instead
Observe before handling the patient, count thoracic and abdominal excursions for a full 15 to 30 seconds, and record effort, noise, and mucous membrane color alongside the rate.
The candidate calculates a drug volume without converting units, or converts pounds to kilograms in the wrong direction, producing a tenfold or 2.2-fold error.
They jump straight to the calculator and omit unit labels, so mg/kg, mg/mL, and lb/kg become interchangeable numbers.
What to do instead
Write the equation with units that cancel, use 1 kg = 2.2 lb, and require a second person to verify high-alert or controlled drugs. Sanity-check the final volume against the patient's size before drawing it up.
The candidate submits a chemistry panel in an EDTA tube or underfills a citrate tube, then labels the tube away from the patient.
The purple-top tube is familiar from hematology, and tube fill lines and order-of-draw rules are treated as memorized trivia rather than sample-integrity requirements.
What to do instead
Match each test to its tube additive: serum or heparin for most chemistry panels, EDTA for CBC, citrate filled to the line for coagulation. Label at the patient's side and reject underfilled or wrong-additive samples.
The candidate wears the same exam gloves from an isolation patient into the general treatment area, or moves from isolation to clean areas without changing PPE.
Gloves create a false sense of protection, and isolation traffic flow is not practiced as a physical route during training.
What to do instead
Treat gloves as patient-specific and perform hand hygiene before and after every patient. Follow the posted clean-to-dirty traffic flow, doff PPE in the correct order at the exit, and use dedicated equipment in isolation.
The candidate tells an anxious client that the pet 'just has a stomach bug' or gives medication instructions without confirming the veterinarian's plan.
They want to reassure the client and fill awkward silence, and they mistake friendly conversation for permission to interpret findings.
What to do instead
Use closed-loop communication: state that the veterinarian will review findings and give the plan, then ask the client to repeat the instructions back. Redirect medical questions to the veterinarian and document the conversation.
