2. A patient reports using benzoyl peroxide 2.5% for acne but doesn’t feel that it is working. The nurse notes papules and nodules on the patient’s face, neck, and back, consistent with moderate acne vulgaris. The nurse will counsel this patient to ask the provider about

a.	adding isotretinoin (Amnesteem) to the treatment regimen.
b.	increasing the benzoyl peroxide to a 5% solution.
c.	taking systemic antibiotics until symptoms improve.
d.	using benzoyl peroxide 10% and a topical antibiotic.

Moderate acne requires a stronger concentration of benzoyl peroxide (10%) and possibly topical antibiotics. Isotretinoin is used for severe cystic acne. Systemic antibiotics are given for severe acne.

3. The nurse is teaching a female patient who will begin taking isotretinoin (Amnesteem) to treat severe cystic acne. Which statement by the patient indicates understanding of the teaching?

a.	“I may get a 3-month supply of the medication with each refill.”
b.	“I must abstain from intercourse while taking this drug.”
c.	“I should avoid strenuous exercise when I am taking this medication.”
d.	“I should take a vitamin A supplement while I am taking the medication.”

 

 

ANS:  C

Serious muscle damage may occur while taking this medication, so patients should avoid strenuous activity which can compound this effect. Patients must get monthly refills and must take a pregnancy test before each refill. Patients should use two reliable forms of birth control, but abstinence is not required. Vitamin A can compound the adverse effects of this medication.

4. A patient who has psoriasis is taking methoxsalen (Oxsoralen) to treat the condition along with receiving therapeutic ultraviolet A. The nurse notes burning and blistering of the patient’s skin. Which action will the nurse take?

a.	Ask the patient about any recent exposure to sunlight.
b.	Explain to the patient that these signs mean the treatment is working.
c.	Report spread of the psoriasis to the patient’s provider.
d.	Tell the patient to take the methoxsalen after the ultraviolet A treatment.

 

 

ANS:  A

Patients taking methoxsalen can develop burning and blistering with exposure to sunlight. These signs do not indicate efficacy of the treatment and do not mean the psoriasis is worsening. There is no indication for taking the drug after the UVA exposure.
