Indeed, the responsibility of dose preparation and administration, under any level of supervision, demands a foundational understanding of pharmacology. This is the concentration of drug when 50% of receptors are occupied: A low K D value indicates that a lower concentration of drug is required to occupy 50% of the receptor, indicating that the drug has a high affinity for the receptor.
