The physician prescribes cromolyn (Intal) for the client with asthma. The nurse identifies that the client correctly understands the purpose of this medication when the client states that the medication will:
1. Suppress an allergic response.
2. Promote bronchodilation.
3. Decrease the risk of infection.
4. Eliminate the need for a rescue inhaler.
1
Rationale:. Cromolyn is a first-line therapy for prophylactic treatment of asthma; it is a mast-cell stabilizer, antiasthmatic, and antiallergic. It does not decrease the risk of infection. It is not a bronchodilator. The medication acts in part by stabilizing the cytoplasmic membrane of mast cells, thereby preventing release of histamine and other mediators. It does not eliminate the need for the rescue inhaler.

A client is admitted to the hospital with a major illness that could have been prevented. A major reason clients in the United States are sicker when they are admitted to the hospital is that:
a. they lack the education to understand when they are ill. b. they are unable to gain access to preventative services so their illness progresses to an acute stage before they seek help. c. more people live in a rural area where it is a difficult to get transportation to a physician. d. their insurance coverage frequently does not pay for preventative services such as immunizations.
