VTNE: Pharmacy and Pharmacology For a veterinary technician, understanding the principle of "volume of distribution" 'Vd' is crucial for which of the following reasons? A. It helps in determining the correct storage conditions for drugs. B. It indicates how extensively a drug distributes into body tissues compared to the plasma. C. It is directly correlated with the speed of drug absorption. D. It determines the drug's palatability to animals. None 1 out of 10 Time is Up! Time's up
