A patient is learning about his new diagnosis of asthma with the asthma nurse. What medication has the ability to prevent the onset of acute asthma exacerbations?
A) Diphenhydramine (Benadryl)
B) Montelukast (Singulair)
C) Albuterol sulfate (Ventolin)
D) Epinephrine
Ans: B
Feedback:
Many manifestations of inflammation can be attributed in part to leukotrienes. Medications categorized as leukotriene antagonists or modifiers such as montelukast (Singulair) block the synthesis or action of leukotrienes and prevent signs and symptoms associated with asthma. Diphenhydramine prevents histamine's effect on smooth muscle. Albuterol sulfate relaxes smooth muscle during an asthma attack. Epinephrine relaxes bronchial smooth muscle but is not used on a preventative basis.

A researcher studies the effect on reading comprehension level of providing fourth-grade boys who are slow and ponderous readers with illustrated comic books for a six-week summer session instead of textbooks,
hypothesizing that reading associated with pictures will results in a higher reading comprehension level. The researcher set a level of significance at p <.05. Analysis of the data from a study indicates that there was a significant difference between the two groups, which were randomly selected and composed of 100 subjects each. However, the experimental comic book group's scores improved less than did the scores of the boys who used the textbooks. The measured p-level was 0.026. What type of finding is this? a. Significant results that are in keeping with those predicted by the researcher b. Nonsignificant results c. Significant results that oppose those predicted by the researcher d. Mixed results
