Questions and Answers
Pharmacokinetics - Correct answer-The study of drug absorption, distribution,
metabolism, and excretion in the body
"What the body does to the drug"
Factors that affect drug absorption (5) - Correct answer-Rate of dissolution
Surface area
Blood flow

,Pharmacodynamics - Correct answer-The study of biochemical and physiologic
effects of drugs on the body and the molecular mechanisms by which those effects
are produced
"What the body does to the drug"
Phamacodynamics: 3 mechanisms of action - Correct answer-Receptor
Enzyme
Non-selective interactions (i.e. chemo)
Types of drug therapy (7) - Correct answer-Acute
Maintenance (HTN/bc)
Supplemental (insulin)
Palliative
Supportive (IV fluid)
Prophylactic
Empirical (broad-spectrum abx)
Idiosyncratic Effect - Correct answer-Unexpected response to medication
Tolerance - Correct answer-Declining response to a drug

, Dependence - Correct answer-Physiological/psychological need for a drug; needs
drug for normal function
Addiction - Correct answer-Compulsive use of a drug despite negative/dangerous
effects
Drug interactions: drug-drug - Correct answer-When 2 drugs compete for
metabolizing enzymes
Drug interactions: food-drug - Correct answer-Grapefruit juice or leafy greens
Drug interactions: additive - Correct answer-1+1 = 2; both provide intended effect
Drug interactions: antagonistic - Correct answer-1+1 = <2; less than desired effect
of one or both drugs
Drug interactions: synergistic - Correct answer-1+1 = >2; sum total effect is greater
than if given alone (i.e. lisinopril + HCTZ)
Drug interactions: incompatibility - Correct answer-1+1 does not equal 2; two IV
drugs given together causing decomposition of one or both drugs
8 rights of medication administration - Correct answer-Patient
Medication
Dose
