VTNE - Vet Tech Prep Timed Exam
Questions
When discussing the equine hoof, which structure produces cells that become the hoof wall?
- Frog
- Sole
- Ergot
- Coronary band ANS: Answer: Coronary band
The hoof wall grows from the coronary band.
The coronary corium produces cells that become the horn of the hoof wall.
It is soft skin tissue such as the cuticles on our fingers.
If the coronary band is ever damaged, the hoof may grow improperly and could cause lameness.
The ergot is a callus-type structure on the underside of the fetlock.
The sole is the bottom of the hoof.
The frog is the structure that is shaped like a heart and extends forward across two-thirds of the sole.
,It grows from front to back where it then merges with the heel periople.
Which internal parasite is a threat to young (but typically not adult) horses?
- Large strongyles
- Tapeworms (Anaplocephala perfoliota)
- Small strongyles
- Parascaris equorum ANS: Answer: Parascaris equorum
Ascarids (Parascaris equorum) can cause significant problems in young (<1 year) horses and can cause
poor growth and a pot-bellied appearance.
A more severe problem occurs when the small intestine becomes obstructed from a heavy worm
burden.
Adult horses develop an immunity to ascarids, so they are typically not a problem in adults.
What zoonotic pathogen might a technician contract from treating a 10 day old dairy calf with diarrhea?
- Staphylococcus aureus
- Francisella tularensis
,- Cryptosporidium parvum
- Leptospira pomona
- E. coli 0157 ANS: Answer: Cryptosporidium parvum
Cryptosporidium is a major cause of calf diarrhea, and just a few oocysts can be infective to humans and
cause diarrhea lasting several days.
A Cavalier King Charles Spaniel presents to your clinic with a history of chronic otitis externa. You
perform an ear cytology showing large numbers of Malassezia. Which of the following types of
organisms is this?
- Gram-negative bacteria
- Gram-positive bacteria
- Ear mite
- Yeast
- Acid-fast bacteria ANS: Answer: Yeast
Malassezia pachydermitis is a yeast/fungus very common in skin and ear infections. It resembles a
bowling pin under the microscope.
, The ear mite is Otodectes.
What does bog spavin describe?
- Abscessation of the hoof wall
- Tarsocrural effusion
- Rotation of the coffin joint
- Inflammation of the superficial digital flexor tendon ANS: Answer: Tarsocrural effusion
Bog spavin is a term used in the equine field.
It describes the accumulation of synovial fluid in the tarsocrural joint.
Rotation of the coffin joint occurs with laminitis.
"Bowed tendon" and tendonitis are the descriptive terms for inflammation of a tendon.
If in the correct location the abscessed hoof wall may be termed a subsolar abscess.
These result in extreme pain and lameness and must be distinguished from laminitis.
You are performing an ear cytology and see some purple bowling pin-appearing organisms. What are
these most likely?
