The nurse teaches a medication class on bronchodilators for clients with asthma. The nurse evaluates that learning has occurred when the clients make which statement?
 
  1. The medication widens the airways because it decreases the production of mucous that narrows them.
  2. The medication widens the airways because it decreases the production of histamine that narrows them.
  3. The medication widens the airways because it acts on the parasympathetic nervous system.
  4. The medication widens the airways because it stimulates the fight-or-flight response of the nervous system.

Question 2

The nurse plans to teach an adolescent about inhalation therapy as part of the treatment plan for the client's asthma. What does the best plan by the nurse include?
 
  1. Inhalation therapy is effective because it provides around-the-clock therapy, as opposed to oral medications.
  2. Inhalation therapy is the preferred treatment for adolescents because it is easier for them to manage.
  3. Inhalation therapy is effective because it provides systemic relief of symptoms as well as local relief.
  4. Inhalation therapy is effective because it goes to the direct site of action in the respiratory tract.

Answer to Question 1

Correct Answer: 4
Rationale 1: Bronchodilators do not decrease the production of mucous.
Rationale 2: Bronchodilators do not decrease the production of histamine.
Rationale 3: Bronchodilators act on the sympathetic nervous system, not the parasympathetic nervous system.
Rationale 4: During the fight-or-flight response, beta2-adrenergic receptors of the sympathetic nervous system are stimulated, the bronchiolar smooth muscle relaxes, and bronchodilation occurs.

Answer to Question 2

Correct Answer: 4
Rationale 1: Inhalation therapy does not provide around-the-clock therapy.
Rationale 2: Inhalation therapy is used for adolescents because it is effective, not because it is easier for them to manage.
Rationale 3: Inhalation therapy does not provide systemic relief of symptoms.
Rationale 4: The major advantage of aerosol therapy is that it delivers the drugs to their direct site of action. Inhalation therapy does not provide around-the-clock therapy. Inhalation therapy does not provide systemic relief of symptoms. Inhalation therapy is used for adolescents because it is effective, not because it is easier for them to manage.
