The nurse is preparing class for patients with
asthma. The nurse will inform the patients that
leukotriene modifiers are used in the treatment of
asthma to
A. assist in opening narrowed airways.
B. suppress the release of histamine and other mediators
from the mast cells.
C. loosen mucus from the airways.
D. prevent serious complications from bacterial infections.
Answer: B
Rationale: Leukotriene modifiers are used in the treatment of patients with asthma
to suppress the release of histamine and other mediators from the mast cells. In
the treatment of patients with COPD, bronchodilators such as sympathomimetics,
parasympatholytics, and methylxanthines are used to assist in opening narrowed
airways; expectorants are used to loosen mucus from the airways, and antibiotics
may be prescribed to prevent serious complications from bacterial infection.
