What is the term that refers to the cost charged to maintain one unit, either one animal or one cage of animals, for one day?

• A. Per subject rate
• B. Per census rate
• C. Per capital rate
• D. Per diem rate

Answer: (D)

The main idea is daily maintenance cost terminology in a lab setting. The term for the amount charged to maintain one unit—whether a single animal or a cage of animals—for one day is per diem rate. This wording reflects the everyday, ongoing cost of housing, feeding, and routine care, plus related facility overhead, on a daily basis. Other terms aren’t the standard way labs label this expense: per census rate would tie cost to a population count at a given time, and per capita rate means cost per individual in a population but isn’t the everyday budgeting label used for animal care. Per subject rate can be used in some contexts, but per diem rate is the conventional, widely understood term for daily unit costs.
