Answer eight questions without outside help. This is placement guidance, not a credential or mastery score.

1. A 100 mg amount is distributed in 20 L. What is the concentration?5 mg/L0.2 mg/L2000 mg/L

2. Which units describe clearance?Volume/timeAmount/timeAmount/volume

3. A straight decline on a semi-log concentration plot usually indicates:Mono-exponential first-order declineNo eliminationA constant concentration

4. Which record is normally a concentration observation?EVID=0 and MDV=0EVID=1 and MDV=1AMT>0 with missing DV

5. What is ETA used to represent in a standard population model?A modeled random deviation between individuals or occasionsThe observed concentrationThe dose amount

6. In a linear IV model with fixed dose, halving clearance does what to AUC?Doubles itHalves itLeaves it unchanged

7. Which statement about convergence is correct?It is necessary but does not prove model adequacyIt proves every parameter is identifiableIt proves the dataset is correct

8. When is an ordinary chi-square likelihood-ratio comparison most defensible?Nested models using the same observations and compatible likelihoodAny two converged modelsModels fitted after different exclusion rules
