Where is the needle placed for a cornual nerve block in an adult cow?
C. On the upper third of the frontal crest, midway between lateral canthus and horn base
The cornual nerve runs under the frontal (temporal) crest; the block is placed on the upper third of the crest, about midway between the lateral canthus and the horn base, just beneath the ridge. The supraorbital foramen and the zygomatic arch are sites for other blocks.

A cornual block uses 8 mL of 2% lidocaine on each side of an adult cow. How many milligrams of lidocaine are given in total?
C. 320 mg
A 2% solution contains 2 g per 100 mL, which is 20 mg/mL. Each side: 8 mL x 20 mg/mL = 160 mg; two sides: 320 mg. 160 mg is only one side; 32 mg comes from reading 2% as 2 mg/mL; 3,200 mg comes from reading it as 200 mg/mL. Volumes and maximum doses must be confirmed against the product label and your national formulary.

Which enucleation approach is preferred for a globe with a large infected or neoplastic lesion, and why?
C. Transpalpebral, because the lids are sutured shut and the conjunctival sac is never opened
In the transpalpebral approach the eyelids are closed first and the lids, conjunctiva and globe are removed together, so infected material and tumour cells are not spilled. The subconjunctival approach causes less bleeding but opens the conjunctival sac. In both approaches the lid margins are removed, never preserved, or a secreting cyst may form.

When an aural haematoma is incised and closed with through-and-through mattress sutures, the sutures should be placed:
C. Parallel to the major auricular vessels, not tied tightly
Mattress sutures through the whole pinna close dead space; they run parallel to the major vessels to avoid ligating them and are not tied too tightly, so the pinna is not strangled. The incision is left open to drain, not sealed; sutures that do not cross the cartilage do not close the dead space.

A proximal paravertebral block uses 15 mL of 2% lidocaine at each of three sites. How much lidocaine is given?
A. 900 mg
2% = 20 mg/mL. Total volume 3 x 15 = 45 mL; 45 mL x 20 mg/mL = 900 mg. 300 mg is a single site; 90 mg treats 2% as 2 mg/mL; 450 mg treats 2% as 10 mg/mL. Volumes must be confirmed against the product label and your national formulary, and the total dose kept below the toxic limit for the animal's weight.

Which acid-base and electrolyte pattern is typical of abomasal displacement or volvulus in cattle?
B. Hypochloraemic, hypokalaemic metabolic alkalosis
Hydrochloric acid secreted into the obstructed abomasum is sequestered there or refluxed into the rumen, so chloride falls and bicarbonate rises, giving hypochloraemic metabolic alkalosis, with hypokalaemia from reduced intake and alkalosis. Metabolic acidosis appears only late, with severe dehydration and poor perfusion.

Which closure is generally recommended for a small-intestinal enterotomy in a dog?
B. Single layer, appositional sutures with monofilament absorbable
Single-layer appositional closure with monofilament absorbable suture heals quickly and does not narrow the lumen. Inverting double layers, appropriate for the rumen, narrow the small intestine; everting patterns delay healing and favour adhesions.

A 15 cm linea alba incision is closed with a continuous suture. Using the 4:1 rule, what is the minimum length of suture that should lie in the wound?
B. 60 cm
The suture-length to wound-length ratio should be at least 4:1 for continuous abdominal closure: 15 cm x 4 = 60 cm. 30 cm is 2:1 and 45 cm is 3:1, both too short (bites too small or too far apart); 120 cm is 8:1, more than the minimum.

In male sheep and goats, which site is the commonest point of urethral obstruction by calculi?
B. Urethral process (vermiform appendage)
The narrow urethral process at the tip of the penis is the commonest site in small ruminants, followed by the distal sigmoid flexure. In cattle the distal sigmoid flexure is the usual site. Calculi lodging in the ureters or bladder neck do not cause the typical male urethral obstruction.

Why are radiographs taken immediately after cystotomy for radio-opaque calculi?
C. To confirm that no calculi were left in the bladder or urethra
Incomplete removal of uroliths is a recognised error after cystotomy, so post-operative radiographs confirm that all radio-opaque stones are gone. Plain radiographs do not show suture-line leakage; wall thickness and closure technique are not assessed this way.
