Answer to Question 1

B
Patients with dementia with Lewy bodies may show benefit with rivastigmine. Visual hallucinations are a hallmark feature of Lewy body dementia.

Answer to Question 2

C
Because this patient has had similar infections in the past, treating empirically is acceptable. The NP must still obtain a culture and sensitivity so that appropriate antibiotic therapy can be provided, even though it is likely that this is a recurrence of the same organism. A culture should always be obtained when possible. A microscopic evaluation is used to determine whether or not a culture should be performed and is not diagnostic.
