|
|
|
Drugs can have either a __________ or ________ effect on the body

|
Law
|
|
|
The responsibility of drug administration is shared by
|
Clients, Health Care Providers, Pharmacists, and Nurses
|
|
|
Pharmacokinetics is the study of
|
Absorption, Distribution, Metabolism and Excretion of Drugs
|
|
|
The process by which a medication passes into the bloodstream is called
|
Absorption
|
|
|
The first step in movement of drugs throughout the body
|
Absorption
|
|
|
In order for absorption to occur you must have the correct _____ of the drug and ____.
|
Form and Route
|
|
|
Absorption by mouth takes
|
30 to 60 minutes
|
|
|
Intramuscular I.M. absorption takes
|
10 to 15 minutes
|
|
|
Which route of absorption is immediate?
|
I.V. Intravenous
|
|
|
The Sublingual route of medication absorption takes time to dissolve but
|
Absorption is Rapid
|
|
|
A Topical or Transdermal drugs release
|
a consistent amount slowly over a long period of time
|
|
|
This route of administration is slow due to poor blood supply to this area
|
Subcutaneous
|
|
|
This route of administration can be unpredictable but may be used if other routes are unavailable or if desired effect is local
|

|
|
|
Food can delay drug

|
Distribution
|
|
|

|
Albumin
|
|
|
Binding Capacity depends on
|

|
|
|

poor blood supply

|
Distribution
|
|
|
