NURS 1140 Exam 2/CSCC Nursing:Pharmacology 1140 questions and verified
answers
Which adverse effect may be observed after administration of tiotropium bromide in a patient
with bronchospasms associated with chronic obstructive pulmonary disease (COPD)? - ANS
Tiotropium bromide (Spiriva) can cause tachycardia as an adverse effect. Abdominal cramps
and nausea are an adverse effect of roflumilast (Daliresp). Dyspepsia and nausea is an adverse
effect of montelukast (Singulair).
Which statement is true regarding the anatomy of the lower respiratory tract? - ANS Human
lungs contain 300 to 500 million alveolar sacs and have a surface area approximately equal to
that of a tennis court. Diaphragmatic and intercostal muscles contract during inspiration and
relax during expiration. Ventilation and perfusion must be equal to maintain homeostasis. Blood
flow through the pulmonary arteries to the capillaries surrounding the alveoli to the pulmonary
veins is called perfusion.
Which is the adult dosage of flunisolide (Aerospan)? - ANS The adult dosage of flunisolide
(Aerospan) is 320 mcg twice daily. The adult dosage of ciclesonide (Alvesco) is between 80 and
160 mcg twice daily. The adult dosage of fluticasone (Flovent HFA) ranges from 88 to 440 mcg
twice daily. The powder inhalation dosage of fluticasone (Flovent HFA) for adults ranges from
100 to 500 mcg twice daily.
Which immunomodulator is used to treat patients with asthma exacerbations caused by
airborne allergens? - ANS Omalizumab is an immunomodulator used to treat patients with
asthma exacerbations. Cromolyn is a mast cell stabilizer used to reduce the frequency of
episodes of allergic rhinitis, bronchospasm, and asthmatic attacks. Roflumilast is a
phosphodiesterase-4 inhibitor used to manage symptoms of severe chronic obstructive
pulmonary disease (COPD). Prednisone is a corticosteroid used to treat acute exacerbations of
asthma or COPD.
Which drug should be avoided in patients with chronic obstructive pulmonary disease (COPD)?
- ANS Codeine (Cotabflu) should not be prescribed to patients with COPD because the drug
causes respiratory depression and may worsen the disease. Prednisone (Deltasone) is a
corticosteroid used to treat acute exacerbations of asthma or COPD. Salmeterol (Serevent
Diskus) is a beta-adrenergic bronchodilating agent used to treat both asthma and COPD.
, Dextromethorphan (Robitussin) is a cough suppressant and does not cause respiratory
depression.
Which antitussive has a combination of antihistamine and antitussive properties? - ANS
Diphenhydramine combines antihistamine and antitussive properties that will decrease the
frequency of a cough. Guaifenesin is an expectorant and will increase the productivity of a
cough. Codeine is a cough suppressant and the standard against which other antitussive agents
are compared; it does not contain antihistamine properties. Dextromethorphan is an effective
cough agent, but does not contain antihistamine properties.
Which drug can be used to treat exercise-induced bronchospasm and asthma? - ANS
Cromolyn sodium (Intal) is a mast cell stabilizer that inhibits the release of histamines and other
mediators of inflammation. It is used to manage exercise-induced bronchospasm and asthma.
Omalizumab (Xolair) is used in the treatment of acute asthmatic exacerbations. Benralizumab
and montelukast (Singulair) are used in the treatment of acute asthmatic symptoms.
Which pulmonary function test determines the maximal rate of airflow produced during forced
expiration? - ANS Peak expiratory flow rate is a pulmonary function test that determines
maximal rate of airflow produced during forced expiration. Forced vital capacity is a pulmonary
function test that determines the maximal volume of air exhaled with maximal forced effort after
maximal inhalation. Forced expiratory volume determines the volume of air forced out of the
lungs by maximal exhalation. Forced expiratory volume in 1 second determines the volume of
air forced out in 1 second to give the rate of flow.
Which long-term control medicine can be prescribed to patients with mild persistent asthma? -
ANS A leukotriene modifier can be prescribed to patients with mild persistent asthma. Oral
corticosteroids and long-acting inhaled beta agonists are prescribed to treat severe persistent
asthma. Medium doses of inhaled corticosteroids can be prescribed for patients with moderate
persistent asthma.
What is the term used in spirometry to identify the volume of air inspired or expired during
normal breathing? - ANS Tidal volume is the volume of air inspired or expired during normal
breathing. Vital capacity is the volume of air exhaled after maximal inspiration to full expiration.
Residual volume is the volume of air left in the lungs after maximal exhalation. Functional
residual capacity is the volume of air left in the lungs after normal exhalation.
Which statement is the definition of vital capacity? - ANS Vital capacity is the volume of air
exhaled after maximal inspiration to full expiration. Forced expiratory volume in 1 second (FEV
1) is the volume of air forced out in 1 second that gives the rate of flow. Forced expiratory
volume (FEV) is the volume of air forced out of the lungs by maximal exhalation. Tidal volume is
the volume of air inspired or expired during normal breathing.
Which drugs suppress the cough center in the brain? - ANS Antitussives act by suppressing
the cough center in the brain. Expectorants liquefy mucus by stimulating the secretion of natural
