  1. What AUC/MIC range did the 2020 vancomycin consensus guideline target for serious MRSA infections, assuming an MIC of 1 mg/L?
    • 100 to 200
    • 400 to 600
    • 800 to 1000
    • 15 to 20
  2. At steady state, how is vancomycin AUC24 related to dose and clearance?
    • AUC24 equals daily dose divided by clearance
    • AUC24 equals clearance divided by daily dose
    • AUC24 equals volume multiplied by half-life
    • AUC24 equals trough multiplied by 24 only
  3. Why did guidance move away from trough-only vancomycin dosing?
    • Troughs cannot be measured in hospitals
    • Troughs are too expensive
    • Troughs predict AUC poorly, and high troughs were linked to kidney injury
    • Troughs only apply to oral dosing
  4. What advantage do Bayesian methods have over traditional two-level steady-state calculations?
    • They need no patient data at all
    • They ignore kidney function
    • They only work in children
    • They can use a single level, levels not at steady state and irregular dosing
  5. In MAP estimation, what does the penalty term weighted by between-subject variability do?
    • It penalizes parameter values that stray far from the population estimate
    • It removes measurement error
    • It sets the MIC
    • It calculates infusion rate
  6. What is shrinkage in Bayesian dosing?
    • The drug's volume of distribution decreasing over time
    • The software reducing every dose by default
    • Clearance falling with age
    • Estimates staying close to population values when samples are few or uninformative
  7. Why does the guide stress accurate records of infusion and sampling times?
    • Billing requires them
    • A timing error of even an hour can shift estimated clearance
    • Software cannot run without a clock
    • They determine the MIC
  8. Which statement reflects the guide's view of so-called AI dosing tools?
    • They are black boxes unrelated to pharmacology
    • They remove the need for pharmacist judgment in all patients
    • Most are built on established pharmacometric methods, with machine learning added for model selection and covariates
    • They only work without drug levels
