Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.
Which drug reverses the sedation produced by medetomidine?
A. Atipamezole
Atipamezole is a selective alpha-2 antagonist. Flumazenil antagonises benzodiazepines, naloxone antagonises opioids, and neostigmine reverses non-depolarising neuromuscular blockers.
A cornual block in a heifer produced no analgesia. On review, the needle had been advanced about 4 cm. What is the most likely reason for failure?
A. The drug was deposited too deep, beyond the superficially placed cornual nerve
The cornual nerve is superficial, under skin and a thin frontalis layer, so the needle needs only about 1 cm; a deep injection misses it. Lidocaine is not inactivated by sinus mucosa, textbook volumes are around 5 to 10 mL, and the nerve lies outside the sinus.
Which pairing of technique and alternative name is correct for paravertebral anaesthesia in cattle?
C. Proximal technique: Farquharson or Hall, also called Cambridge
The proximal technique is associated with Farquharson and Hall (Cambridge), and the distal technique with Magda and Cakala (Cornell). The inverted L is a separate field block, not a paravertebral technique.
At which site is a caudal epidural most commonly given in adult cattle?
D. The first intercoccygeal space (Co1-Co2)
The first intercoccygeal space, or the sacrococcygeal space, is found by pumping the tail and feeling the first moveable joint. The lumbosacral site is used for high epidurals in small ruminants and pigs and routinely in dogs and cats; the atlanto-occipital site is for cerebrospinal fluid collection.
What are the three components of the equine 'triple drip' used for short total intravenous anaesthesia?
D. Guaifenesin, ketamine and xylazine
Triple drip combines a centrally acting muscle relaxant (guaifenesin), a dissociative (ketamine) and an alpha-2 agonist (xylazine or another), infused for procedures of up to about an hour. The other combinations are not the equine triple drip, and halothane is an inhalant.
A horse under inhalant anaesthesia is hypotensive with poor contractility. Which drug is commonly infused to improve cardiac contractility?
B. Dobutamine
Dobutamine is a predominantly beta-1 adrenergic agonist that increases contractility and cardiac output and is widely used to support blood pressure in anaesthetised horses. Acepromazine causes vasodilation, furosemide reduces volume and propranolol lowers contractility.
Why may some operators include the third lumbar nerve (L3) in a paravertebral block for a flank incision in cattle, and what is the risk?
C. To extend analgesia caudally, risking weakness of that side's pelvic limb
L3 contributes to the caudal flank; blocking it helps with caudally extended incisions, but because lumbar nerves also contribute to the femoral nerve, pelvic-limb weakness on the blocked side may follow. The vagus and phrenic nerves are not near the lumbar transverse processes, and L3 does not supply the udder.
