The nurse is trying to explain to a colleague the difference between the LD50 and the ED50. Which of the following responses best describes the difference? “LD50 shows the clinician the legal standard of the drug, and the ED50 shows the emergency dose.” “They are really the same. Both show the clinician what will happen when the client takes themedication.” “Both values measure 50% of the study population’s response. LD describes lethal dose, and ED represents effective dose.” “These values are just used in animal studies; they have no relationship to human medication dosing.”
