MS Vet Tech common mistakes
MS Vet Tech · Understand the traps and how to avoid them.
Confusing directional and positional terminology (cranial/caudal, dorsal/ventral, proximal/distal, palmar/plantar) when describing a lesion or reading a procedure prompt, then selecting the answer that matches the wrong axis.
Candidates memorize term lists as isolated vocabulary rather than as a coordinate system tied to a standing animal, so they translate terms on the fly under time pressure and flip axes, especially proximal/distal versus cranial/caudal on limbs.
What to do instead
Practice by mentally (or physically) placing a standing quadruped and pointing to each direction before answering; drill paired opposites in sets of four and state the reference plane aloud. Build a habit of writing the axis (e.g., 'toward head = cranial') in scratch notes at the start of the exam block.
Applying a restraint hold appropriate for a dog to a cat or a fractious patient, or choosing a hold that restricts the airway or a limb in a way that risks injury, when asked to select the safest handling method.
Candidates learn one 'standard' hold and reuse it; they underweight species differences (cats' fragile cervical spine and defensive escape behavior, brachycephalic airway compromise, avian and exotic fragility) and underestimate how restraint choice changes with the procedure.
What to do instead
For each restraint question, first identify the procedure, the species, and the patient's temperament, then eliminate any option that compromises airway, circulation, or joints. Study species-specific holds as a matrix (dog lateral, cat scruff versus towel, chemical restraint thresholds) and rehearse the 'least restraint necessary' principle.
Calculating a drug dose correctly but failing to convert units or to distinguish concentration from total dose (mg versus mg/mL versus mg/kg), producing an answer off by a factor of 10 or 100.
Candidates rush the arithmetic and skip dimensional analysis; they also confuse percent solutions (a 2% solution is 20 mg/mL, not 2 mg/mL) and forget to cross-check that the drawn volume is physically plausible for the patient size.
What to do instead
Always write the unit equation with cancellation (kg × mg/kg ÷ mg/mL = mL) before computing, and sanity-check the result against a known volume (e.g., a 10 kg dog should not receive 50 mL of a typical injectable). Memorize percent-to-mg/mL conversion and practice a mixed set of unit-conversion items weekly.
Mixing up which blood tube (EDTA, heparin, serum separator, citrate) is correct for a given test, or answering a hematology or chemistry question based on the wrong anticoagulant's effect.
Candidates memorize tube colors without linking them to the analyte or the mechanism; they do not connect EDTA's calcium chelation to why it invalidates calcium and some enzyme assays, or why citrate tubes must be filled to the line.
What to do instead
Build a tube-to-test table keyed by analyte and mechanism, not color alone. For each sample question, state the analyte first, then the required tube, then the reason. Practice spotting interference scenarios (hemolysis, lipemia, underfilled citrate tube).
Choosing an anesthetic protocol or monitoring parameter without matching it to the patient's ASA status, species, or procedure, such as selecting a mask-induction plan for a vomiting patient or missing that capnography reflects ventilation rather than oxygenation.
Candidates memorize drug lists and monitor names separately from the clinical decision chain; they confuse what each monitor measures (SpO2 = oxygenation, ETCO2 = ventilation, blood pressure = perfusion) and overlook premedication goals.
What to do instead
For each anesthesia item, walk a fixed sequence: patient risk (ASA), premedication goal, induction route (airway protection if regurgitation risk), maintenance, and the monitor that detects the most likely complication. Drill monitor-to-physiology mapping until automatic.
Answering emergency or critical-care questions with a definitive diagnosis or a slow diagnostic workup instead of the immediate stabilization step (e.g., choosing radiographs before fluid resuscitation in a shocky patient).
Candidates treat emergency items like general medicine items and default to 'diagnose first'; they have not internalized the ABC-and-perfusion priority framework or triage categories.
What to do instead
Adopt a reflex: for any emergency stem, ask 'what kills this patient in the next five minutes?' and select the intervention that addresses airway, breathing, circulation, or glucose/temperature first. Practice triage sorting and shock-recognition items until stabilization-first becomes the default.
Misidentifying dental anatomy or periodontal staging, such as confusing which tooth is the carnassial, mislabeling the maxillary fourth premolar versus mandibular first molar, or understating attachment loss when assigning a stage.
Candidates learn dental charts visually but not the numbering and quadrant logic, and they conflate gingivitis (reversible, stage 1) with periodontitis stages that require attachment-loss criteria.
What to do instead
Memorize the modified Triadan system by quadrant and practice naming teeth from descriptions, not pictures. Build a staging ladder (stage 1 = gingivitis only; stages 2–4 by percentage attachment loss) and apply it to written case vignettes.
Confusing husbandry and nutrition requirements across species, such as applying dog feeding or housing norms to cats (obligate carnivores, taurine requirement), rabbits (hindgut fermenters needing continuous forage), or reptiles, and answering preventive-care items with the wrong life stage schedule.
Candidates generalize from the most familiar species and memorize vaccination or deworming schedules without anchoring them to species physiology and life stage; they also miss that some 'preventive' products are toxic to certain species.
What to do instead
Study nutrition and husbandry as species-specific profiles (metabolic type, essential nutrients, housing, social needs) and pair each with its preventive schedule. Flag species-toxicity facts (e.g., permethrin in cats, ivermectin sensitivity in some breeds) as high-yield memory anchors.
Overstepping or understepping the veterinary technician's legal scope, such as selecting an answer in which the technician gives a diagnosis or prognosis, prescribes, or performs surgery, or conversely defers a task the technician may legally perform under supervision.
Candidates know the general principle of 'supervision' but not the specific task boundaries, and they conflate ethical best practice with legal scope; they also overlook record-keeping and informed-consent obligations.
What to do instead
Build a task-by-task scope table (diagnosis and prognosis = veterinarian; client education, sample collection, anesthesia monitoring, dental prophylaxis under supervision = technician, per state practice act). For each ethics or compliance item, ask 'who is legally responsible and what documentation is required?'
Selecting an imaging view or technique that is contraindicated or poorly matched to the question, such as choosing a ventrodorsal radiograph for a patient with respiratory distress, or answering a thoracic or abdominal question with the wrong projection or contrast study.
Candidates memorize view names without linking each view to the structure it highlights or the patient-positioning risk; they also confuse which modality answers which clinical question (survey versus contrast versus ultrasound).
What to do instead
Create a view-to-indication table (e.g., lateral for free air and cardiac silhouette, VD/DV for symmetry and lung fields, orthogonal views always) and note positioning contraindications for unstable patients. For each item, state the clinical question first, then the modality and view that answers it with least risk.
