VTNE Anesthesia: What's Actually Tested
The second-largest VTNE domain in our practice bank. Depth-of-plane cues, titrated shock-dose fractions, and machine leak-checks — plus the least-appropriate-drug stems that reward disciplined elimination.
Anesthesia is the second-largest domain in our bank — 13.1% of the questions, 224 items. That weight is the reason to work it early: points here are dense, and the mistakes are predictable enough to drill out.
What's actually tested
Traps to expect
Drill these
- Give shock-dose crystalloid in titrated fractions, not the full 90 mL/kg at once.
- Match vital trends to depth: hypoventilation means support ventilation, not a deeper vaporizer.
- Drop tube size for brachycephalics and prep a range.
- On least-appropriate-drug stems, eliminate the safe options and take what remains.
FAQ
What is the canine crystalloid shock dose?
It's quoted near 90 mL/kg in the dog, but the tested point is that you deliver it in titrated boluses — often about a quarter at a time — and reassess, rather than pushing the whole volume at once.
How do I size an ET tube for a brachycephalic dog?
Their tracheas are disproportionately narrow, so drop one to two sizes below what the weight chart suggests and prepare a range around it. A tube that's too large is a pressure-necrosis trap.
What does a rising end-tidal CO₂ mean under anesthesia?
During maintenance it often signals hypoventilation or a rebreathing problem — for example a stuck unidirectional valve. The fix is to support ventilation and check the circuit, not to deepen the plane.
