  The nurse would anticipate the prescriber to order which one of the following drugs? a. Zolpidem (Ambien)

Answer to Question 1

A
The proper index of renal function in the elderly is creatinine clearance.
A renal biopsy would not be indicated as an index of renal function without other initial labora-tory/diagnostic testing.
A urinalysis analyzes urine, not renal function.
Blood urea nitrogen can evaluate renal function; however, it also can be altered by other factors, such as hydration status; therefore, it is not the best indicator of renal function.

Answer to Question 2

B
Zaleplon does not produce next day sedation or a hangover feeling and therefore would be the expected medication for the prescriber to order.
Zolpidem, flurazepam, and trazodone may cause next day sedation and/or a hangover feeling and therefore would not be appropriate for this patient.
