Pharmacology
Asthma is treated according to severity. For quick relief of a single asthmatic symptom a(n) _________
drug is recommended.
a. oral beta1 and beta2 antagonist
b. inhaled glucocorticoid
,c. short-acting inhaled beta2 agonist
d. theophylline preparation - Correct answer-c. short-acting inhaled beta2 agonist
The advantage of using a glucocorticoid inhaler instead of an oral glucocorticoid is that it:
a. increases the risk for adrenal suppression
b. minimizes the risk for adrenal suppression
c. increases the need for more oral glucocorticoid
d. necessitates less glucocorticoid - Correct answer-b. minimizes the risk for adrenal suppression
A client who uses an inhaler is taught the strategies to prevent Candida infections. Which of the
following would the nurse include in the instructions?
a. soak the spacer in alcohol between uses
b. do not use a spacer
c. rinse the mouth with water after each use
d. use antifungal agent such as fluconazole (Diflucan) prophylactically - Correct answer-c. rinse the
mouth with water after each use
Albuterol (Proventil), a beta2 adrenergic agonist and a sympathomimetic, is an effective drug to control
asthma. The action of a beta2 adrenergic is to:
a. decrease mucus production
b. enhance bronchodilation
c. promote bronchoconstriction
d. promote bronchospasm - Correct answer-c. rinse the mouth with water after each use
A patient has been admitted to the hospital with acute asthma and has had nausea and vomiting. The
drug history reveals that the patient has been taking theophylline (Elixophyllin) for 3 weeks. Prior to the
administration of theophylline, the nurse should check the orders for
, a. renal function tests
b. a plasma drug level
c. a basal metabolic panel (BMP)
d. a complete blood count (CBC) - Correct answer-b. a plasma drug level
A nurse counsels a patient using two different types of asthma inhalers: a short acting beta2 agonist and
a corticosteroid. When the patient questions the purpose of the steroid inhaler, the nurse's best
response would be that glucocorticoids
a. work rapidly in acute attacks
b. are used as prophylaxis for chronic asthma
c. help prevent respiratory infections
d. are used only when exposed to environmental allergens - Correct answer-b. are used as prophylaxis
for chronic asthma
While caring for a patient with cirrhosis or hepatitis, the nurse knows that abnormalities in which phase
of pharmacokinetics may occur?
a. Absorption
b. Distribution
c. Metabolism
d. Excretion - Correct answer-c. Metabolism
A patient has an order for tetracycline antibiotic and has been instructed to avoid taking the medication
with foods, beverages, or drug that contains calcium, iron, or magnesium. The patient takes the
antibiotic along with a daily multivitamin, not realizing that the vitamin contains iron. What effect may
this have on the tetracycline?
a. Absorption
b. Distribution
