Question 1
A parent asks a nurse about giving diphenhydramine [Benadryl] to a child to relieve cold
symptoms. Which response by the nurse is correct?
• A. "Benadryl must be given in higher doses to provide relief for cold symptoms."
• B. "Intranasal glucocorticoids are more effective for treating cold symptoms."
• C. "Nasal antihistamines are more effective for treating cold symptoms."
• D. "Because histamine doesn’t cause cold symptoms, Benadryl would not be effective."
Answer: D - Histamine does not contribute to symptoms of infectious rhinitis; therefore,
antihistamines are of no use in treating cold symptoms. Giving antihistamines in higher doses does not
provide relief for infectious rhinitis. Intranasal glucocorticoids are not useful for infectious rhinitis. Nasal
antihistamines are not effective for treating infectious rhinitis.
A patient with asthma will be using a metered-dose inhaler (MDI) for delivery of an inhaled
medication. The provider has ordered 2 puffs to be given twice daily. It is important for the
provider to teach this patient that:
• A. the patient should inhale suddenly to receive the maximum dose.
• B. the patient should activate the device and then inhale.
• C. the patient should store the MDI in the refrigerator between doses.
• D. the patient should wait 1 minute between puffs.
Answer: D - When two puffs are needed, an interval of at least 1 minute should separate the first
puff from the second. Sudden inhalation can cause bronchospasm. The patient should begin inhaling
and then activate the device. There is no need to store the drug in the refrigerator.
Question 3
A patient takes oral theophylline twice daily for chronic stable asthma. After developing an
infection, the patient went to an after-hours clinic where ciprofloxacin was prescribed. What
action will the patient’s primary provider take when the patient follows up the next day?
, • A. Prescribe a different antibiotic.
• B. Reduce the theophylline dose.
• C. Increase the theophylline dose.
• D. Discontinue the theophylline and prescribe a long-acting β agonist.
Answer: B - Fluoroquinolone antibiotics increase theophylline levels, so the dose of theophylline
may need to be reduced to prevent theophylline toxicity. Changing antibiotics, increasing the
theophylline, and changing to a LABA are not indicated.
Question 4
A patient who recently recovered from acute bronchitis reports a lingering dry cough that
prevents sleep. Which over-the-counter medication will the provider recommend to best manage
the symptoms?.
• A. Guaifenesin
• B. Fexofenadine/pseudoephedrine
• C. Phenylephrine drops
• D. Diphenhydramine
Answer: D - Diphenhydramine is effective in suppressing cough and also has sedative effects when
used in doses to suppress cough. Fexofenadine/pseudoephedrine is a combination
antihistamine/decongestant and will not help with cough. Guaifenesin helps make coughs more
productive but will not suppress cough or help with sleep. Phenylephrine drops have decongestant
properties.
Question 5
A patient with seasonal and perennial rhinitis requests a prescription for the most effective drug
for treating this condition. Which medication will the provider recommend?
• A. Loratadine
• B. Intranasal cromolyn sodium
• C. Fluticasone propionate
• D. Pseudoephedrine
Answer: C - Intranasal glucocorticoids, such as fluticasone propionate, are the most effective
drugs for prevention and treatment, because they prevent or suppress all the major symptoms of
allergic rhinitis (congestion, rhinorrhea, sneezing, nasal itching, and erythema). Pseudoephedrine is an
oral sympathomimetic used to reduce nasal congestion associated with allergic rhinitis. It has no effect
on other symptoms. Loratadine, an oral antihistamine, reduces sneezing, rhinorrhea, and nasal itching
only and is less effective than intranasal glucocorticoids. Intranasal cromolyn sodium is moderately
effective in the treatment of allergic rhinitis, but the benefits are much less than those of intranasal
glucocorticoids.
