    Study Notes

    Potency and Efficacy

    • Potency measures the amount of drug required to produce a specific effect
    • Efficacy measures the maximum response or effect a drug can produce
    • Potency is commonly determined by the dose required to produce a specific effect, often represented by EC50 (Effective Concentration 50%), which is the concentration of a drug that produces 50% of its maximum effect
    • A drug with higher efficacy is more therapeutically beneficial as it produces a greater maximum response

    Drug Safety

    • The six rights of drug safety are: right patient, right drug, right dose, right route, right time, and right documentation
    • When handling medications, the label should be read at least three times: when taking the medication from the shelf, when preparing the medication for administration, and when administering the medication to the patient
    • If a drug has unusual characteristics, such as unusual color, odor, or texture, it should not be administered and the pharmacist or supplier should be contacted
    • If unsure about a physician's order for medication, the nurse should clarify the order with the physician before administering the medication
