Question 1

Which of the following statement regarding oxygen toxicosis is false:

1. It is often irreversible
2. Blindness has been reported in humans
3. Related to lipid per oxidation
4. In patients on long-term oxygen therapy, FIO2 should be less than 80%

Answer 1

4. In patients on long-term oxygen therapy, FIO2 should be less than 80%. FIO2 should be less than 60%

Question 2

Which of the following statement regarding primary ciliary dyskinesia is true:

1. It is idiopathic
2. It is heterogenous group of inherited autosomal dominant diseases
3. It could involve other ciliated tissue
4. It could be associated with a reduced production of mucous

Answer 2

It could involve other ciliated tissue. In fact otitis media, reproductive problems, renal fibrosis and dilation of renal tubules can be seen.

1. It is idiopathic= it is a genetic disorder
2. It is heterogenous group of inherited autosomal dominant diseases = it is recessive
3. it could be associated with a reduced production of mucous = usually, there is an excessive production of mucous (difficult to rid off)

Question 3

Based on human medicine, which one is not one of the 3 hallmark of asthma?

1. Obstruction/airways limitation
2. Reversible airways inflammation
3. Airways hyperresposiveness
4. Smooth muscle atrophy

Answer 3

Smooth muscle atrophy

Question 4

Which is the most common cause of pneumothorax in cats?

1. Idiopathic
2. Trauma
3. Asthma
4. Neoplasia

Answer 4

Asthma

Question 5

Which of the following statement regarding pleural effusion is false:

1. Low glucose is indicative of sepsi
2. High concentration of NT-proBNP is indicative of cardiac origin
3. FIP effusion is aseptic exudate
4. Chylothorax is composed by high concentration of small lymphocytes

Answer 5

Low glucose is indicative of sepsi

In fact, this is not as clear as abdominal effusion

Question 6

Which is the contraindication for nebulization of N-acetylcysteine?

1. Toxic in cats
2. Cannot be nebulized
3. Cause bronchoconstriction
4. Direct contact cause necrosis of the respiratory mucosa

Answer 6

3. Cause bronchoconstriction

Question 7

Identification of loud inspiratory crackles in the absence of alveolar lung pattern, can be an excellent clue of:

1. Pulmonary edema
2. Pulmonar fibrosis
3. Emphysema
4. Pneumothorax

Answer 7

2. Pulmonar fibrosis

Question 8

Which one of the following is not a potential cause of pulmonary hypertension in dogs?

1. Generalized alveolar hypoxia
2. Left-side congestive heart failure
3. Living at high altitude
4. Treatment with alpha-adrenergic agonists

Answer 8

4. Treatment with alpha-adrenergic agonists

1. Increased
2. Decreased
3. Remains the same
4. I dont care

Answer 9

Remains the same

Question 10

In toxicity due to CO there is :

1. decreased PO2 and SaO2
2. increased PO2 and decreased SaO2
3. stable PO2 and decreased SaO2
4. decreased PO2 and increased SaO2

Answer 10

stable PO2 and decreased SaO2
