LO Vet Tech common mistakes
LO Vet Tech · Understand the traps and how to avoid them.
Choosing a directional or positional term by its everyday English meaning instead of its anatomical meaning, so that a limb described as 'distal to the carpus' is labelled proximal, or 'cranial' is used for a structure on the rear limb.
Candidates study terminology as a vocabulary list without anchoring it to a reference posture. Under time pressure they fall back on colloquial usage, and terms like cranial/caudal, dorsal/palmar, and proximal/distal get applied relative to the observer rather than relative to the standing animal.
What to do instead
Before answering, mentally place the animal in a standing position and orient yourself: head is cranial, tail is caudal, and on the distal limb use dorsal/palmar (forelimb) or dorsal/plantar (hindlimb). Practise by labelling a simple limb diagram from memory in both directions, then describe five clinical scenarios (a wound, a swelling, a fracture) using only directional terms until the reference posture becomes automatic.
Describing a restraint hold as 'firm' or 'secure' without naming the specific contact points, the direction of force, and the body part controlled, so that answers about feline or canine restraint are chosen on general impression.
Restraint is learned hands-on and candidates remember the feel of a hold rather than its mechanics. Exam questions that ask which hold limits a specific behaviour (scratching, biting, backing out of a collar) require identifying which body part is controlled and how, which a vague memory cannot supply.
What to do instead
For each common hold, write a three-part note: what is immobilised, which hand or device does it, and what movement it prevents. Include the cat scruff versus full-body towel wrap, the lateral recumbency hold, the muzzle, and the Elizabethan collar alternative. Then match each hold to the behaviour it defeats, and rehearse the pairing aloud until the mechanics, not the impression, drive the answer.
Calculating a drug dose correctly but reporting it in the wrong unit or concentration, for example giving milligrams when the question asks for millilitres of a solution, or confusing a percent solution with milligrams per millilitre.
Candidates memorise dose rates in mg/kg and stop there, treating the concentration step as an afterthought. Percent concentrations are especially error-prone because 1 percent equals 10 mg/mL, a conversion that is easy to invert under exam pressure.
What to do instead
Adopt a fixed three-step written method for every calculation: dose in mg/kg times body weight gives total mg; total mg divided by concentration in mg/mL gives mL; check the answer against a sanity range. Drill the percent-to-mg/mL conversion until it is instant, and always write the unit at each step so a mismatched unit is visible before you select an option.
Selecting an anaesthetic or analgesic protocol by drug class name alone, without matching it to the patient's condition, species, or procedure duration, so a contraindicated agent is chosen for a patient with a specific risk.
Candidates learn drug categories as lists and associate each with a use, but exam items often hinge on a single contraindication, such as an agent that should be avoided in a patient with a particular organ dysfunction or a species-specific sensitivity. The category label feels sufficient, so the qualifier is skipped.
What to do instead
Build a one-page matrix of anaesthetic and analgesic agents with columns for species caution, organ-system caution, onset, duration, and route. For every practice question, state the patient's key risk factor before looking at the options, then eliminate any agent that conflicts with it. Review the matrix weekly so contraindications are recalled alongside indications.
Confusing sterile technique with clean technique during a surgical preparation question, for example describing a gown or drape as sterile once it has contacted a non-sterile surface, or reaching across a sterile field.
Asepsis is taught as a set of rules but candidates often remember the sequence of steps without the principle behind each. When a question describes a breach, they evaluate whether the step was performed rather than whether sterility was maintained, and the breach goes unnoticed.
What to do instead
Learn asepsis as a single governing principle: anything that contacts a non-sterile surface is no longer sterile, and the sterile field is defined by its boundaries. Practise identifying breaches in written scenarios, naming the exact object and the exact contact that contaminated it. Include the gown cuff, the drape edge, the instrument handle, and the gloved hand in your examples.
Answering a dental question using tooth numbering or a charting convention from the wrong system, or describing a dental procedure without distinguishing the crown from the root and the surrounding periodontium.
Dental anatomy is often studied from charts without practising the numbering system, and candidates may carry over a numbering convention learned elsewhere. Periodontal disease questions also require knowing which tissue is affected, which a surface-level memory of 'dental disease' does not supply.
What to do instead
Learn the tooth numbering system used in your region as a fixed grid and practise labelling a full mouth from memory in both directions. For periodontal questions, separate gingiva, periodontal ligament, cementum, and alveolar bone, and state which is affected before choosing an answer. Review a dental charting example and describe each finding in anatomical terms.
Interpreting a radiograph by describing what is visible without first establishing the projection, the patient position, and the normal appearance of that structure, so a normal variant is called abnormal or a lesion is missed.
Candidates look at the image first and reason from the finding, skipping the orientation step. Without a normal reference for that projection, symmetry and expected silhouettes cannot be assessed, and the answer is driven by the most striking feature rather than the correct one.
What to do instead
Use a fixed reading routine for every image: identify projection and position, check symmetry and alignment, then assess each organ or bone against its expected appearance. Practise on normal films until the expected silhouette is familiar, then apply the same routine to abnormal films. Write the routine down and follow it in every practice question.
Reporting a laboratory result without checking it against the reference interval, the sample quality, or the patient's species, so a haemolysed sample or a species-specific normal is treated as a true abnormality.
Candidates focus on the number and the test name, treating the result as an isolated fact. Sample handling artefacts and species differences are taught separately and are not retrieved when the question is framed around a single value.
What to do instead
For every laboratory question, run a three-part check: is the value inside the species reference interval, could the sample have been affected by handling (haemolysis, lipaemia, delayed processing, wrong tube), and does the result fit the clinical picture. Practise by reviewing reports with known artefacts and identifying which values should not be trusted.
Prioritising an emergency intervention by the order it appears in a textbook protocol rather than by the patient's immediate threat to life, so a stable step is chosen before airway, breathing, or circulation is addressed.
Protocols are memorised as sequences and candidates reproduce the sequence without reassessing the patient. Exam scenarios deliberately present a distracting finding, and the memorised order overrides the primary survey.
What to do instead
Apply a primary survey in a fixed order every time: airway, breathing, circulation, then disability and exposure. For each scenario, state the immediate threat before considering any intervention, and only then select the action that addresses it. Practise with scenarios that include a distracting but non-lethal finding so the habit of reassessment is reinforced.
Answering a nursing-care question about monitoring, nutrition, or comfort without linking it to the patient's specific condition, age, or species, so a general care statement is chosen over the one that fits the case.
Nursing care is often studied as general principles, and candidates treat it as common sense rather than as condition-specific assessment. Questions that ask what to monitor next or how to adjust care require matching the intervention to the patient's actual risk.
What to do instead
For each common condition, write the specific monitoring parameters and nursing adjustments it demands, including temperature, hydration, pain score, mentation, and feeding route. When answering, name the patient's main risk first and choose the option that monitors or addresses it. Review by converting each general principle into a condition-specific example.
