A four-month-old filly is presented with a four-day history of lethargy, heavy
breathing, cough, and decreased appetite. Temperature: 104.9 F (RR: 99.0-100.6 F); HR:
72 bpm (RR: 28-40 bpm); R: 44 bpm (RR: 10-14 bpm).
On lung auscultation asymmetrically-distributed crackles and wheezes are audible.
Some areas have no breath sounds and dull resonance on thoracic percussion. A
,lateral chest radiograph shows consolidated nodular lung lesions and mediastinal
lymphadenopathy.
Pneumonia due to Rhodococcus equi infection is confirmed based on culture and
polymerase chain reaction results on a transtracheal wash.
Which one of the following choices is the most appropriate treatment?
A) Chloramphenicol and aminophylline
B) Procaine penicillin G and gentamicin
C) Tilmicosin
D) Clarithromycin and rifampin
E) Vancomycin and atropine (if bronchospasm is observed)
Give this one a try later!
D) Clarithromycin an rifampin
A 1.5-year old spayed female cat presents with a 7-day history of vocalizing, rolling,
and allowing a male neutered cat in the household to mount her. The cat has gone
through one similar episode 1 month ago. She otherwise has been behaving normally
and has no other health problems. You performed an ovariohysterectomy on the cat
at 3 months of age. You perform vaginal cytology which shows some cornified
epithelial cells but is inconclusive. You measure serum luteinizing hormone of 0.2
ng/ml (normal for an ovariectomized female is >1 ng/ml). Which of the following is the
most appropriate course of action?
A) Measure serum testosterone levels
B) Measure serum estrogen and progesterone levels
C) Exploratory laparotomy to remove the ovarian remnant
D) Order MRI of t he brain to rule out a pituitary tumor
Give this one a try later!
C) Exploratory laparotomy to remove the ovarian remnant
, An adopted adult male cat from a shelter with an unknown vaccination history is

B - Need an ELISA test in 12 weeks to confirm diagnosis
C - Cat may be vaccinated for FeLV
D - Need a Western blot test to confirm diagnosis
E - Strong chance of lifelong FeLV infection
Give this one a try later!
E) Strong chance of lifelong FeLV infection
An alpaca is presented in poor body condition with an unkempt coat,
patchy alopecia, and severe pruritus and crusting of the extremities.. A

diagnostic step?

B) Check thyroid status and bluetongue titers
C) Tell Yoda found his brother
D) Punch biopsy
E) Skin scraping and microscopic exam
Give this one a try later!

A ten-year-old male neutered Irish Setter is presented with an acute
onset of severe abdominal distension, non-productive retching, and
collapse. Physical exam reveals a tense, distended abdomen. A right
