NV Vet Tech common mistakes
NV Vet Tech · Understand the traps and how to avoid them.
Calculating a drug dose from the patient's actual body weight in kilograms when the drug label or formulary specifies a dose in mg/m² or a fixed dose, or omitting the species-specific conversion factor when moving between mg/kg and mg/lb.
Candidates memorize a handful of mg/kg doses and then apply them reflexively; unit conversion (lb to kg, mg/kg to mg/m², percent solution to mg/mL) is where most arithmetic errors occur, and many candidates round early, compounding the error across the drawn volume.
What to do instead
Write the dimensional analysis out in full on scratch paper (weight × dose ÷ concentration), carry units through every step, and round only at the final volume. Practice converting a 1:1000 epinephrine solution to mg/mL and a 50 mg/mL drug to mg/kg doses until the unit chain is automatic. State the final volume in mL and cross-check it against a sane syringe size before drawing.
Confusing the concentration expressed as a percentage with mg/mL (e.g., treating 2% lidocaine as 2 mg/mL rather than 20 mg/mL), or misreading a ratio dilution such as 1:1000 versus 1:10,000.
Percentage and ratio concentrations are taught early and assumed known, so candidates skip the conversion under time pressure; the decimal-place error is invisible because the resulting number looks plausible on a syringe.
What to do instead
Memorize the anchor that 1% = 10 mg/mL and 1:1000 = 1 mg/mL, and derive every other concentration from those two anchors. Before answering, restate the concentration in mg/mL explicitly in your own words, then compute the volume. Flag any answer whose volume differs from your mental estimate by a factor of 10.
Selecting an anesthetic protocol or premed without accounting for the patient's ASA status, concurrent disease (e.g., hepatic or renal impairment, cardiac disease, brachycephalic conformation), or the procedure's expected duration and pain level.
Candidates learn drug classes in isolation and then match a drug to a species rather than to a patient; the exam deliberately presents comorbid patients to test whether the candidate adjusts the plan rather than reciting a default protocol.
What to do instead
For every anesthesia question, first assign an ASA class and list the two or three comorbidities that change drug choice. Then justify each drug by its effect on those comorbidities (e.g., avoid ketamine in a patient with seizure history or raised intracranial pressure; reduce inhalant requirement in a hypovolemic patient). Build a one-page matrix of drug contraindications and review it before the exam.
Monitoring depth of anesthesia by a single parameter (usually jaw tone or eye position) and failing to integrate heart rate, respiratory rate, mucous membrane color, capillary refill time, blood pressure, and end-tidal agent concentration into a single assessment.
Textbook descriptions of anesthetic stages are memorized as discrete signs, but real patients show conflicting signs; candidates answer with the single most familiar indicator and miss the question that asks what to do when parameters disagree.
What to do instead
Practice reading a full monitoring sheet as a whole: state what each parameter is telling you, then state the integrated conclusion and the next action. Learn which signs are most reliable at each depth (e.g., palpebral reflex loss, jaw tone, tear production) and which are confounded by premedication. Answer anesthesia-monitoring questions by naming the parameter that most directly reflects the problem being described.
Failing to recognize and prioritize life-threatening emergencies in the correct order, for example spending time on diagnostics before establishing an airway or vascular access, or missing that a patient in shock needs fluid resuscitation before sedation.
Candidates answer the question that was asked rather than the question the patient needs; emergency questions are written so that the most familiar intervention is often not the first one, and triage sequencing is tested more heavily than any single drug or dose.
What to do instead
Apply a fixed ABC (airway, breathing, circulation) and perfusion-assessment framework to every emergency stem before reading the answer choices. Practice ranking interventions by immediacy and be able to state why each earlier step must precede the later one. Review the classic presentations of GDV, urethral obstruction, hypovolemic shock, and anaphylaxis so the first intervention is reflexive.
Interpreting a laboratory result in isolation without reference to the patient's hydration status, age, species, sample quality, or the analyzer's reference interval, and therefore misclassifying a hemolyzed or lipemic sample as a true abnormality.
Candidates memorize normal ranges and then compare a single number to them, forgetting that hemolysis elevates potassium and falsely lowers some analytes, that young animals have different reference intervals, and that a value outside the interval may be clinically insignificant.
What to do instead
For every lab question, first identify the sample type and quality, then note the patient's species and age, then interpret the value in context. Learn the common artifacts of hemolysis, lipemia, and icterus on a chemistry panel and CBC. When a single value is abnormal, ask what else on the panel would change if it were real, and answer from that pattern.
Placing a surgical site or preparing the patient without confirming the correct side, procedure, and patient identity, or clipping and prepping in a way that contaminates the field (e.g., clipping after scrubbing, prepping in a circular motion that drags hair into the incision line).
Candidates treat aseptic preparation as a memorized list of steps rather than a sequence with a rationale, so they cannot tell which step is out of order; patient-identity and site-verification questions are treated as administrative trivia rather than safety-critical.
What to do instead
Learn the prep sequence with its reason attached: clip first (outside the prep area, away from the wound), then alternate scrub and rinse from the incision outward, then apply the final antiseptic. Memorize that clipping after scrubbing reintroduces contamination. For site-verification questions, answer with the behavior that confirms patient, side, and procedure against the record before the patient is draped.
Handling dental radiographs and periodontal probing as optional extras, or interpreting a dental radiograph without assessing the full tooth root and alveolar bone rather than only the visible crown.
Dentistry is under-weighted in many study plans, so candidates skim it; they then answer from surface visual inspection, missing that most dental disease (root resorption, periapical lucency, bone loss) is invisible without imaging and probing.
What to do instead
Treat full-mouth dental radiographs and a six-point periodontal probe chart as the standard of care in every dental question. Practice identifying the normal radiographic landmarks (lamina dura, alveolar margin, pulp cavity) so you can spot their loss. Learn the probe depths that define gingivitis versus periodontitis and the tooth-by-tooth extraction complications most likely to be tested.
Choosing a pain-management plan based only on the procedure performed, without reassessing the patient's pain score, and defaulting to a single analgesic class rather than multimodal analgesia.
Candidates learn that 'surgery equals NSAID' and stop there; the exam tests whether the candidate reassesses and escalates, and whether they know the contraindications (e.g., NSAIDs in renal compromise or with concurrent corticosteroids) that force a different plan.
What to do instead
For every pain question, state the assessment tool used (e.g., a validated pain scale or the Colorado State University acute pain scale), the score, and then build a plan that combines at least two classes acting at different points (opioid plus NSAID plus local block, for example). Memorize contraindications to each class and the signs of inadequately controlled pain. Reassess after intervention and state what change in plan the reassessment triggers.
Answering practice-management and ethics questions from personal preference rather than from the legal and professional framework, for example describing what a technician may do without confirming the state's practice act, or breaching client confidentiality in a hypothetical scenario.
Candidates assume ethics questions are common sense, so they do not study the underlying rules; the exam tests specific concepts such as the veterinary-client-patient relationship, informed consent, record retention, and the boundaries of delegated tasks.
What to do instead
Study the definitions of the VCPR, informed consent, and the technician's scope of practice as concepts, and learn that scope is set by the state practice act, not by the employer. For each scenario, identify who holds the legal responsibility and what documentation is required. Practice stating the rule first, then applying it, rather than reasoning from what feels right.
