A patient may develop neutropenia from using topical Silvadene for burns. The primary care NP
should:
A) Continue the treatment without monitoring
B) Monitor complete blood count periodically
C) Switch to a different topical antibiotic
D) Increase the frequency of Silvadene application
Correct Answer: B) Monitor complete blood count periodically

A low-carbohydrate, high-protein diet may:
A) Increase the risk of ketosis
B) Enhance drug absorption
C) Reduce serum potassium levels
D) Decrease gastric pH
Correct Answer: A) Increase the risk of ketosis

change to over-the-counter status in order to:
A) Increase production costs
B) Extend market exclusivity
