MI Vet Tech common mistakes
MI Vet Tech · Understand the traps and how to avoid them.
Calculating a drug dose from the labeled concentration without first converting units, so a patient receives 10x or 100x the intended amount (e.g., treating a 1% solution as 1 mg/mL instead of 10 mg/mL, or mixing mg/kg with a percent solution).
Candidates memorize dose rates but practice them almost exclusively in mg/kg, then meet concentrations expressed as percent, mg/mL, or units/mL under time pressure and skip the conversion step.
What to do instead
Adopt a fixed written sequence for every calculation: patient weight in kg, dose rate, desired dose in mg, concentration in mg/mL, volume in mL. Convert percent to mg/mL explicitly (1% = 10 mg/mL) and show the conversion on paper before dividing.
Drawing up and administering a vaccine or injectable without confirming the route, needle gauge/length, and injection site appropriate to species and product (e.g., giving an IM product subcutaneously, or using an intradermal route on a cat).
Candidates focus on the drug name and volume and treat route and needle choice as automatic, so species differences and product-specific route requirements get lost.
What to do instead
Before every injection, state aloud the product, dose, route, and site, and match needle length to patient size and tissue depth. Learn the standard sites per species (e.g., IM in the epaxial/lumbar or quadriceps muscles, SC in the interscapular or lateral flank) and check the label for route restrictions.
Monitoring depth of anesthesia by a single parameter (usually jaw tone or eye position) and failing to integrate heart rate, respiratory rate, reflexes, and blood pressure, so a light plane or excessive depth is missed.
Textbook lists of signs are memorized as separate facts, and candidates latch onto whichever sign they can assess most easily in a busy room.
What to do instead
Use a structured anesthesia record with a fixed checklist at each 5-minute interval: heart rate and rhythm, respiratory rate and character, mucous membrane color, CRT, palpebral reflex, jaw tone, and blood pressure if available. Interpret the combination, not one sign, and document trends rather than single readings.
Breaking the sterile field during surgical preparation or draping (reaching over an open pack, letting a gown or glove touch a non-sterile surface, or repositioning a drape after it is placed) and continuing as if nothing happened.
Candidates concentrate on completing the task quickly and have not internalized which contacts are considered contamination, so they do not recognize the breach in real time.
What to do instead
Learn the specific rules: sterile items contacting non-sterile surfaces are contaminated; a drape is not adjusted once placed but replaced; hands stay above the table and in view. Practice the sequence slowly with an instructor calling breaches until recognition becomes automatic, and when in doubt, re-glove or re-drape.
Charting dental disease from a quick visual glance, missing pathology on the lingual/palatal surfaces, below the gingival margin, or on the far side of the mouth, and recording a grade without probing.
Dental charts are often completed under time pressure, and candidates rely on the most visible teeth (buccal surfaces of the carnassials and incisors) rather than a systematic examination.
What to do instead
Use a consistent quadrant-by-quadrant sequence and probe every tooth at multiple sites, recording probing depth, attachment loss, furcation involvement, and mobility. Chart findings as you go rather than from memory afterward, and note that a normal-looking crown does not rule out disease below the gingiva.
Running in-house laboratory tests without validating the analyzer or running controls, and interpreting a single abnormal value as diagnostic without confirming it or considering pre-analytical error.
Candidates treat the machine output as ground truth and have not been taught which errors occur before the sample reaches the analyzer.
What to do instead
Check analyzer status and controls before patient samples, and know the common pre-analytical errors: hemolysis, lipemia, delayed processing, wrong tube or anticoagulant, and improper storage. Repeat unexpected values and correlate with the clinical picture before drawing conclusions.
Missing or misinterpreting early signs of patient deterioration (increased respiratory effort, changes in mentation, subtle mucous membrane color change, falling urine output) and waiting for a dramatic change before escalating.
Candidates assess vital signs as a checklist to be completed rather than as a trend to be tracked, and they are reluctant to escalate to a veterinarian without an obvious emergency.
What to do instead
Record vital signs on a timed flowsheet and compare each set with the previous ones. Learn species-specific normal ranges and report any trend moving in the wrong direction, even if the value is still within normal limits, using a structured report (parameter, value, trend, concern).
In an emergency, delaying vascular access and initial stabilization to complete a full history, full physical examination, or diagnostics first.
Candidates have practiced thorough examination as the default and have not rehearsed the triage-first sequence, so they default to the routine approach under stress.
What to do instead
Learn and drill the ABC sequence: airway, breathing, circulation, then disability. Place IV access and begin stabilization while obtaining history from the owner in parallel, and treat life-threatening problems before completing diagnostics.
Positioning a patient for radiographs without considering the anatomic region and needed projections, producing images that are rotated, cropped, or missing the structure of interest (e.g., a lateral thorax that excludes the diaphragm or a limb study with only one view).
Candidates focus on machine settings and restraint and treat positioning as secondary, and they do not routinely take orthogonal views.
What to do instead
Before exposure, confirm the anatomy included, the centering point, and that the patient is straight and not rotated. Take at least two orthogonal views of any region, include the joints above and below a long bone, and check the image for collimation and positioning before releasing the patient.
Confusing restraint with force: applying a tight hold or improper scruff/neck restraint on a fearful or painful patient, causing escalation, injury, or a bite.
Candidates equate control with physical strength and have not practiced low-stress handling or recognized fear and pain signals early.
What to do instead
Use the least restraint necessary, approach calmly, and use towel wraps, muzzle, or chemical restraint when indicated. Learn fear and pain body language, and pause and reassess when the patient escalates rather than tightening the hold.
