Psychopharmacology
- D.
Psychopharmodynamics
- 3.Which of the following is the slowest drug absorption?

Oral administration
- D.
Inhalation
- 4.A low therapeutic index is an indicator that ____________.
- A.
Care must be given to prescribing because the margin of safety is small.

Inactivation
- B.
Depot binding
- C.
Covalent binding

- 6.A drug with high affinity generally requires ________.
- A.
A higher dose
- B.
A lower dose
- C.
A same size dose as it would with a low affinity
- D.
The drug to be administered intravenously
- 7.____________ is the study of what a drug does to the body.
- A.
Pharmacokinetics
- B.

- 9.Why are many drugs used to treat mental illness lipid-soluble?
- A.
You can attach chemicals in a more dense form onto a lipid-soluble drug than a water-soluble drug
- B.
The immune system would recognize water-soluble drugs as invaders and fight them
- C.
The blood brain barrier is only a barrier for water-soluble molecules so lipid soluble drugs pass through
- D.
Water-soluble drugs would alter the pH value of the bloodstream and therefore have significant side effects compared to lipid-soluble drugs.

- A.
Direct agonist
- B.
Direct antagonist
- C.
