QUESTION
In horse, a light red foam coming from both nostrils and harsh sound over the trachea and bronchi indicates?
OPTIONS
(A) Pulmonary haemorrhage
(B) Pharyngeal haemorrhage
(C) Nasal haemorrhage
(D) Pulmonary congestion
ANSWER
(A) Pulmonary haemorrhage
EXPLANATION
Bilateral light-red froth from the nostrils together with harsh tracheobronchial sounds in a horse is consistent with blood originating from the lower respiratory tract, as occurs in pulmonary hemorrhage. Pharyngeal or nasal hemorrhage usually produces more localized bleeding, whereas pulmonary congestion alone does not specifically account for hemorrhagic foam.
