Question 1

Which nerve block is most appropriate for standing flank laparotomy in cattle?

Accepted Answer

Paravertebral nerve block

Answer

Paravertebral nerve block (proximal or distal) desensitizes the flank region by blocking the spinal nerves T13, L1, and L2, providing analgesia and muscle relaxation for standing laparotomy.

Question 2

A horse presents with a large colon displacement that is not correctable via rolling. Which surgical approach is preferred?

Accepted Answer

Ventral midline celiotomy

Answer

Ventral midline celiotomy provides the best access to the entire large colon and allows manual correction of displacements that cannot be resolved non-surgically.

Question 3

What is the primary concern when performing a rumenotomy in cattle?

Accepted Answer

Contamination of the peritoneal cavity with rumen contents

Answer

Spillage of rumen contents during rumenotomy can cause severe peritonitis; meticulous isolation of the surgical field and careful incision technique are essential to prevent contamination.

Question 4

Which suture pattern is classically used to close the equine linea alba after celiotomy?

Accepted Answer

Large-bite simple continuous with #2 or #3 polyglactin 910

Answer

Large-bite simple continuous suture with large-gauge absorbable monofilament or polyglactin incorporates adequate fascial tissue to resist the significant intra-abdominal pressure in horses.

Question 5

In small ruminants, what is the most common site for urethral obstruction by uroliths?

Accepted Answer

Urethral process (vermiform appendage)

Answer

The urethral process is the narrowest point of the small ruminant urethra and is the most frequent site of urolith lodgment, making amputation of this structure the first-line treatment.
