MULTIPLE CHOICE

1. A patient has questions regarding a recently prescribed antitussive agent. Which response by the nurse is the best?
a.
“It will eliminate your cough at night.”
b.
“It will reduce the frequency of your cough.”
c.
“It should be used in the morning.”
d.
“It should be taken before sleep.”

ANS: B
Antitussive agents act by suppressing the cough center in the brain. The expected therapeutic outcome is reduced frequency of nonproductive cough to promote rest. Antitussive agents should be taken as prescribed by the health care provider. Antitussives are not likely to eliminate a cough. Antitussives should be taken throughout the day.

2. Which is a common expectorant in over-the-counter medications?
a.
Dextromethorphan
b.
Diphenhydramine
c.
Guaifenesin
d.
Codeine

ANS: C
Guaifenesin is used for symptomatic relief of conditions characterized by a dry, nonproductive cough such as the common cold, bronchitis, laryngitis, pharyngitis, and sinusitis. Guaifenesin is also used to remove mucous plugs from the respiratory tract. Dextromethorphan is an antitussive. Diphenhydramine is an anticholinergic agent with antihistaminic and antitussive properties. Codeine is an antitussive.

3. What is the reason for administering potassium iodide to a patient with emphysema?
a.
To increase blood iodide levels
b.
To decrease mucus viscosity
c.
To reduce metabolic needs of the body
d.
To decrease bronchial irritation

ANS: B
Potassium iodide acts as an expectorant by stimulating the bronchial glands to secrete. This will decrease the viscosity of mucous plugs, which makes it easier for patients to cough up the dry hardened plugs blocking the bronchial tubes. Potassium iodide is not given to increase serum potassium iodide levels. Potassium does not reduce metabolic needs of the body or bronchial irritation.

4. Within minutes of the initiation of a nebulizer treatment with a sympathomimetic bronchodilator, the patient turns on his call light and states that he feels “panicky” and his heart is racing. Which action will the nurse take?
a.
Reassure the patient this is expected.
b.
Add more diluents to the nebulizer.
c.
Administer a sedative.
d.
Stop treatment and notify the health care provider.

ANS: D
Sympathomimetic drugs increase sympathetic nervous stimulation. Symptoms such as nervousness, palpitations, tremors, tachycardia, and anxiety typically are dose related. These symptoms should be reported to the health care provider immediately because the patient may require a decreased dosage. These symptoms could lead to further complications if allowed to persist and are not common adverse effects. Although this may be a common result, it is not an expected outcome. Diluting the medication would not decrease the dose. Although a sedative might be appropriate for the patient, this is not the intervention of choice.

5. Premedication assessments before the use of anticholinergic bronchodilating agents should verify that the patient has no history of which condition?
a.
Diabetes
b.
Hypertension
c.
Liver disease
d.
Glaucoma

ANS: D
Anticholinergic bronchodilating agents cause mydriasis (dilation of the pupils) and cycloplegia (loss of power in the ciliary muscle); therefore, they should not be used in patients with a history of closed angle glaucoma. Diabetes, hypertension, and liver disease are not affected by the use of anticholinergic bronchodilating agents.
