Question 20

An 82-1b (37-kg), 8-year-old neutered male German Shepherd mixed-breed dog is being evaluated because of a two-month history of decreased exercise tolerance. The client reports that the dog had two episodes of “profound weakness” on walks during the past week. The dog seems comfortable at home, but his “heart is racing all the time.” Two years ago, another veterinarian diagnosed the dog with hypothyroidism and prescribed oral levothyroxine 0.8 mg twice daily. Dosage was reevaluated one month after initiation of treatment and was determined appropriate. Appetite, urination, and bowel movements are normal. Body condition score is 6/9. Temperature is 101.2°F (38.4°C) and heart rate is 180 beats/min. The dog is panting.
Physical examination detects a pulse deficit that occurs three to five times each minute. No other abnormalities are noted.

Question 59

A 4-year-old female Maltese dog has had the progressive onset of tremors, excitability, and panting during the past hour. She has had two tonic seizures during this time. The dog whelped five healthy puppies four weeks ago. Her temperature is 103.9°F (39.9°C). On examination, the dog is very anxious, has muscle tremors, and is hyperresponsive to tactile stimulation. Which of the following is the most appropriate immediate pharmacologic treatment of this dog?
A) Calcium gluconate intravenously
B) Dexamethasone intravenously
C) Diazepam intravenously
D) Phenobarbital intravenously
E) Potassium bromide orally

Answer 59

A
In this case, the symptoms and the history suggest that the Maltese may be experiencing eclampsia, a condition that can occur in nursing females due to low calcium levels. The signs of tremors, excitability, panting, seizures, and hyperresponsiveness align with this condition.

Given that eclampsia is typically treated with calcium supplementation, calcium gluconate would be the appropriate choice. It helps to rapidly increase calcium levels in the blood, which can alleviate the neurological signs and prevent further seizures.

Diazepam, while useful for managing seizures, would not address the underlying cause of the tremors and seizures related to hypocalcemia. Therefore, in this scenario, calcium gluconate is the correct treatment to administer.

Question 60

A 5-year-old Simmental cow who is used as a donor for embryo transfer is evaluated because of the acute onset of anorexia and lethargy. She has been flushed six times; the most recent flushing occurred 10 days ago. Rectal temperature is 104.0°F (40.0°C). During physical examination, the cow is reluctant to move and periodically kicks at her abdomen. On rectal palpation, the left kidney is grossly enlarged and has a smooth texture. When stimulated to urinate, the urine is grossly hematuric; numerous blood clots and fibrin are present. Which of the following is the most appropriate treatment?

A) Administration of gentamicin intravenously
B) Administration of procaine penicillinG intramuscularly
C) Long-term catheterization of the bladder
D) Surgical removal of the enlarged kidney
E) No treatment is indicated

Answer 60

B

Question 61

A 10-year-old commercial beef cow has had a gradually diminished appetite and progressive weight loss over the past two months. Feces are dry and scanty. She continues to drink water. Physical examination shows distention of the left paralumbar fossa and ventral right abdominal wall.

A) Administration of bismuth subsalicylate with sucrose
B) Administration of magnesium hydroxide
C) Exploratory laparotomy
D) Salvage to slaughter
E) Surgicl creation of a rumen fistula

Answer 61

D

This is a right displaced abomasum. Prognosis for this is GUARDED.

For LDA you could do medical management - Calcium, transfaunation, gastric stimulants OR roll and toggle, abomasopexy, omentopexy

Rumenotomy is for frothy bloat or traumatic reticuloperitonitis

Question 62

Question 64

A 4-year-old second-lactation Holstein cow that is 150 days in milk has been in anestrus since calving. On palpation of the rectum, a cystic structure that is 3 cm in diameter is identified on the left ovary. Administration of which of the following is the most appropriate initial treatment?
A) Follicle-stimulating hormone followed by gonadotropin-releasing hormone in 15 days
B) Gonadotropin-releasing hormone followed by prostaglandin in 15 days
C) Melengestrol acetate followed by prostaglandin in 19 days
D) Prostaglandin followed by melengestrol acetate in 19 days

Answer 64

B

GnRH stimulates the release of LH from the anterior pituitary, which can induce the ovulation of a follicular cyst. In this case, GnRH is used to promote the rupture of the cyst and the initiation of a new estrous cycle.
After administering GnRH and allowing time for the cyst to either ovulate or regress, prostaglandin (PGF2α) is administered around 15 days later to lyse the corpus luteum if present (from the cyst or other source). This ensures the cow will return to estrus.

Question 65

Fifteen of a group of 200, 7-month-old feedlot calves are lame. The calves arrived at the feedlot approximately one month ago, and one week later 40 of the animals developed pneumonia. These calves were treated with oxytetracycline, and the pneumonia appeared to resolve. On physical examination, the affected calves have swellings in the carpi, tarsi, and stifles with distention of associated tendon sheaths, and a stiff gait. Two calves are euthanized. Postmortem examination shows fibrinous pleuritis and papillary muscle necrosis. Which of the following organisms is the most likely cause of these signs?
A) Arcanobacterium (Actinomyees) pyogenes
B) Histophilus somni (Haemophilus somnus)
C) Mannheimia (Pasteurella) haemolytica
D) Pasteurella multocida
E) Salmonella typhimurium

Answer 65

B

The combination of pneumonia, polyarthritis, pleuritis, and myocardial necrosis in these calves is most consistent with an infection caused by Histophilus somni. This organism is known to cause systemic infections in cattle that include respiratory, joint, and cardiac involvement, making it the most likely cause in this case.

Remember: Bovine Respiratory Disease Complex is made up of Enzootic Pneumonia and Shipping Fever

• Enzootic Pneumonia is mostly caused by P. multocida and is seen in thin, recently weaned calves.
• Shipping Fever is mostly seen in any age calf that underwent a stressful event and is usually caused by M. haemolytica but occasionally P. multocida and H. somni.

In cases of Coxiella you see placental thickening.

In cases of Campylobacter you see gray foci

Question 68

In October, six mixed-breed beef cows and three calves are being evaluated because of a one-day history of droopy ears, squinting, rubbing their heads on objects, and ataxia. Four days ago, the cows and calves escaped from their pasture and were found the next day eating the lush clover, buckwheat, and ryegrass in a food plot a neighbor had planted to attract deer to his property. The cattle were returned to their home pens and fed their usual diet of timothy hay and a commercial grain supplement. Today, vital signs of one affected calf are: temperature 102.5°F (39.2°C), heart rate 85 beats/min, and respiratory rate 35 breaths/min. Examination shows blepharospasm, as well as edema, erythema, serous exudate, and matting of the hair, which are most severe on the ears, eyelids, external nares, and lips. Animals with white faces seem most severely affected. Which of the following is the most likely cause of these findings?
A) Dermatophilosis
B) Infectious bovine keratoconjunctivitis
C) Infectious bovine rhinotracheitis
D) Primary photosensitization
E) Secondary photosensitization

Answer 68
