Question

1. what is the purpose of a nebulizer?

hypoxia
bronchodilation
bronchoconstriction
vomiting

1. where does a cortical cataract occur?

at birth
on the edge of the lens nucleus
in the middle of the lens
on the back of the lens

Explanation:

• Question 37: Nebulizers are used to deliver medication in a mist form. Bronchodilation is the widening of the airways. Nebulizers often contain bronchodilators to open up the bronchial tubes. Hypoxia is a lack of oxygen (not the purpose of a nebulizer). Bronchoconstriction is the narrowing of airways (opposite of what nebulizers help with). Vomiting is unrelated to the main function of a nebulizer.
• Question 38: A cortical cataract occurs on the edge of the lens nucleus. It is not present at birth (congenital cataracts are different). It is not in the middle (nuclear cataracts are more central). It is not on the back (posterior sub - capsular cataracts are on the back).

Answer:

1. bronchodilation
2. on the edge of the lens nucleus
