Answer:
Foreign body airway obstruction.
Explanation:
Foreign body airway obstruction may be defined as the medical condition in which the breathing tube is completely or partially blocked due to the foreign substances. The cough develops suddenly in this condition.
The child has difficulty in breathing means that his breathing tube shows blockage. This has happened suddenly when he was playing with friends. The foreign substance present in air has entered in the body and causes difficulty in breathing. Hence, this describes the condition of foreign body airway obstruction.
Thus, the correct answer is option (a).
Answer:
The statement that is true about leukotrienes is that they create excess mucus in the airways (last option).
Explanation:
Leukotrienes are inflammatory mediators, derived from arachidonic acid, in whose presence occurs increased vascular permeability in tissues, leading to inflammatory processes.
The presence of leukotrienes has been related to the development of allergic reactions, mainly in the respiratory tract, producing edema in the mucosa, contraction of the smooth muscles of the airways and increased production of mucus
in the airways.
the other options are not correct because leukotrienes:
- <em>Produce contraction of the smooth musculature around the airway.
</em>
- <em>Are related to the production of bronchial asthma.
</em>
- <em>Are inflammatory (chemical) mediators. </em>
