The nursing instructor prepares to teach student nurses about how mean effective doses of medications are related to clinical practice. As a result of the instruction, what is the best understanding of the student nurses?
1. About 50% of patients will experience severe side effects from the drug.
2. Some patients will respond differently depending on their ethnic background.
3. About 50% of patients will not experience any effect from the drug.
4. Some patients will require more or less than the average dose of the drug.
Correct Answer: 4
Rationale: The mean effective dose predicts how 50% of the population will respond to the average dose of the drug. Some patients will require more or less of the drug. The mean effective dose is not related to ethnicity. The mean effective dose does not predict how many patients will experience severe side effects from the drug. The mean effective dose does not predict that 50% of patients will not experience any effect of the drug.
