9
Q

What policies should you follow for the proper storage and distribution of medication and narcotics?

10
Q

  3. blood flow to site of administration
  4. body surface area
  5. lipid solubility of medication
11
Q

medications placed on mucous membranes and respiratory airways

A

are absorbed quickly

12
Q

What form of medications are absorbed more quickly?

A

medications already in a liquid state are absorbed more quickly

13
Q

What areas absorb more quickly?

A

vascular areas absorb more quickly (mucous membranes)

14
Q

The majority of medications are absorbed in

A

the small intestine

because small intestine is highly permeable, has high blood flow, and large surface area

15
Q

What type of medications can cross cell membranes easily?

A

highly lipid soluble medications cross cell membranes easily.
food in the stomach may also be a factor in absorption.

16
Q

Pharmacokinetics: Factors that in influence distribution

  1. circulation
  2. membrane permeability
  3. protein binding
17
Q

The effect of Circulation on distribution of medications

A

ex) patients with heart failure have impaired circulation, therefore slowing medication delivery

18
Q

The effect of Membrane Permeability on distribution of medications

blood brain barrier allows only fat-soluble medications to pass into the brain and cerebral spinal fluid

19
Q

The effect of Protein Binding on distribution of medications

A

the degree to which medications bind to serum proteins (albumin) affects distribution

20
Q

Metabolism

A

failure of organs that metabolize drugs puts patients at risk for medication toxicity
(ex. liver degrades many harmful chemicals before entering the tissues, so if liver is impaired, elimination of drugs is slower, causing an accumulation of drugs and risk for toxicity.)

21
Q

Excretion

A

-elimination of drug through lungs, liver, kidneys, bowels, and exocrine glands.

36
Q

Biological Half-Life

A

time it takes for the excretion process to lower the amount of unchanged medication by half

37
Q

What are the effects of aging on metabolism?

A
  • liver mass shrinks
  • hepatic blood flow and enzyme activity declines
  • metabolism drops to one half to two thirds the rate of young adults
