NR 508 Week 7 QuizNR 508: ADVANCED PHARMACOLOGY
,Question 1
pts
A primary care NP sees a child who has honey-crusted lesions with areas of erythema around the
nose and mouth. The child’s parent has been applying Polysporin ointment for 5 days and reports
no improvement in the rash. The NP should prescribe:
neomycin.
Polysporin with a corticosteroid.
a systemic antibiotic.
Correct!
mupirocin.
Treatment with a topical antiinfective agent should be reevaluated in 3 to 5 days if there is no
improvement. Polysporin ointment is bacteriostatic, not bacteriocidal. Mupirocin is indicated for
impetigo caused by Staphylococcus aureus, which is most common in children. Neomycin is an
aminoglycoside and is not effective against S. aureus. A systemic antibiotic is not indicated
unless the mupirocin fails to treat the infection. Adding a corticosteroid would increase the
likelihood that the infection will worsen.
Question 2
pts
A primary care nurse practitioner (NP) sees a patient who has a 1-week history of watery, painful
eyes with copious amounts of clear discharge and a sore throat. The NP observes bilateral
erythema of the conjunctivae and palpates enlarged preauricular lymph nodes. The NP should
prescribe _____ drops.
ganciclovir
nonsteroidalantiinflammatory
, Correct Answer
ophthalmic antibiotic
You Answered
sympathomimetic ophthalmic
The patient has symptoms of viral conjunctivitis; clear discharge is characteristic. Antibiotic
drops are often prescribed to prevent a bacterial infection. Ganciclovir drops are antiviral drops
but are reserved for patients with a clinical diagnosis of herpetic keratitis by an ophthalmologist.
Sympathomimetic drops are used to treat glaucoma. Nonsteroidal antiinflammatory drops are
sometimes used for allergic conjunctivitis.
Question 3
pts
An NP sees a patient who reports persistent seasonal symptoms of rhinorrhea, sneezing, and
nasal itching every spring unrelieved with diphenhydramine (Benadryl). The NP should
prescribe:
Correct!
triamcinolone (Nasacort AQ).
phenylephrine (Neo-Synephrine).
cromolyn sodium (Nasalcrom).
azelastine (Astelin).
According to randomized controlled trials in patients with allergic rhinitis, oral antihistamines
are used first to help control itching, sneezing, rhinorrhea, and stuffiness in most patients.
Intranasal corticosteroids are indicated for patients who do not respond to antihistamines.
Azelastine is a topical antihistamine. Phenylephrine is a decongestant, and this patient does not
have congestion. Cromolyn sodium is less effective than intranasal corticosteroids.
