MULTIPLE CHOICE

1)Which statement regarding the action of decongestants is true?

1. 1. Decongestants act by decreasing inflammation within the respiratory tract.
   2. Decongestants must be used cautiously as they can induce asthma attacks.
   3. Decongestants act primarily to reduce symptoms associated with allergy.
   4. Decongestants act by reducing the immune response of lymphocytes.

2. A patient with allergies has been prescribed an antihistamine. Which response by the patient demonstrates understanding of the action of antihistamine drugs?
   1. “Antihistamines act by increasing the production of acetylcholine”
   2. “Antihistamines act by blocking histamine receptors in tissues”
   3. “Antihistamines act by increasing dilation of blood vessels”
   4. “Antihistamines act by blocking the release of histamine”

3. An older adult patient with glaucoma reports taking an antihistamine for allergy symptoms. What adverse effect of antihistamines would you alert this patient about?
   1. Ototoxicity
   2. Ocular “floaters”
   3. Excessive tearing
   4. Increased intraocular pressure

4. Which statement would be true in teaching a patient with hypertension about taking antihistamines?
   1. Antihistamines need to be taken 2 h apart.
   2. Antihistamines can cause the blood pressure to rise.
   3. Antihistamines can cause a slowing of the pulse rate.
   4. Antihistamines must be taken at the same time as antihypertensives.

5. What is a common side effect of inhaled anti-inflammatory drugs for asthma?
   1. Anemia
   2. Bronchoconstriction
   3. Cutaneous itching
   4. Dry mouth

   3. Bronchoconstriction
   4. Large, flabby alveoli

7. Which patient would not be a candidate for a leukotriene inhibitor as part of the treatment plan for mild asthma?
   1. An adult patient with a history of liver disease
   2. An older patient with cognitive impairment
   3. An adolescent with allergic rhinitis
   4. A patient with depression

8. An adolescent with a history of asthma needs a drug to prevent exercise-induced asthma while playing high school sports. Which drug would be appropriate for this use?
   1. Cromolyn sodium
   2. Theochron
   3. Sus-Phrine
   4. Proventil

9. You are teaching a patient with newly diagnosed asthma about using the prescribed drugs to manage acute asthma symptoms. Which of the following statements made by the patient would indicate your teaching was effective?
   1. “I will keep my short-acting bronchodilating inhaler with me at all times.”
   2. “I will take my cromolyn sodium 5 min after asthma symptoms begin.”
   3. “I will take montelukast (Singulair) at the first sign of an asthma attack.”
   4. “I will take my decongestant and corticosteroid nasal spray each day.”

10. What is the most common route used to deliver short-acting beta-adrenergic agonists?
    1. Oral
    2. Intravenous
    3. Transdermal
    4. Inhalation

11. Why are long-acting beta-adrenergic agonists not useful during an actual acute asthma attack?
    1. They are likely to cause allergies.
    2. They need time to build up an effect.
    3. They take too long to be absorbed by the intestinal tract.
    4. They reduce inflammation rather than relax bronchial smooth muscle.

12. Which of the following patients is most at risk for overdose from the oral mucolytic drug guaifenesin?

    2. A 60-year-old with a history of COPD

    2. They have no role in preventing bronchoconstriction or inflammation.
    3. They are all given intravenously.
    4. They have severe systemic side effects.
