A patient is seen by a primary care NP to evaluate a rash. The NP notes three ring-shaped lesions with elevated, erythematous borders and two smaller, scaly patches on the patient's abdomen.
 
  The patient has not used any over-the-counter medications on the rash. The NP should prescribe: a. terbinafine (Lamisil).
  b. oxiconazole (Oxistat).
  c. ketoconazole (Nizoral).
  d. miconazole (Lotrimin AF).

Question 2

Persistent atrial fibrillation (AF) is diagnosed in a patient who has valvular disease, and the cardiologist has prescribed warfarin (Coumadin). The patient is scheduled for electrical cardioversion in 3 weeks.
 
  The patient asks the primary care nurse practitioner (NP) why the procedure is necessary. The NP should tell the patient: a. this medication prevents clots but does not alter rhythm.
  b. if the medication proves effective, the procedure may be canceled.
  c. there are no medications that alter the arrhythmia causing AF.
  d. to ask the cardiologist if verapamil may be ordered instead of cardioversion.

Answer to Question 1

D
When initiating treatment for tinea corporis, start with an older agent, such as miconazole, because this is available over-the-counter and in generic form and is cheaper. Other agents may be used if the infection does not respond to miconazole or if there are localized side effects to the product.

Answer to Question 2

A
Persistent AF lasts longer than 7 days and episodes fail to terminate on their own, but episodes can be terminated by electrical cardioversion after therapeutic warfarin therapy for 3 weeks. Warfarin does not alter AF. B-Blockers, calcium channel blockers, and digoxin are sometimes given to alter the rate. Verapamil is not an alternative to cardioversion for patients with persistent AF.
