14
Q

16
Q
Each step in pharmacokinetics is influenced by what two things?

- Movement of medication from where it entered body to bloodstream
18
Q
What are 5 factors that influence absorption of a medication?

19
Q
Why would lipid solubility affect absorption of medication?

Acidic
21
Q
What does distribution mean in pharmacokinetics?
A
Transport of medication via bloodstream to site of drug action
22
Q
What are two factors that influence drug distribution?
A
- Properties of medication
- Physiology
23
Q
What are some reasons physiology could play a role in drug distribution throughout the body
A
- Circulation
- Membrane permeability (ex. blood brain barrier, only lipids can pass through)
- Protein binding
- Amount of medication
24
Q
What can lower albumin in blood mean for medication distribution?
A
Less= more free medication, which can lead to toxicity
25
What is the first pass effect?
The concentration of a drug is greatly reduced before it reaches the systemic circulation
( the first pass through the liver greatly affects bioavailability of the drug)
26
What is bioavailability
the proportion of a drug or other substance that enters the circulation when introduced into the body and so is able to have an active effect.
27
What is metabolism in regards to pharmacokinetics
The breakdown of medication into an inactive/less active form
28
How does metabolism occur?
As enzymes detoxify, degrade and remove biologically active chemicals
29
Where can biotransformation occur?
Mostly in liver
| Can occur in lungs, kidneys, blood and intestines
30
If kidneys aren't functioning, what can there be a risk of when taking medication?
Toxicity
31
What is excretion in regards to pharmacokinetics?
Process of medication exiting the body through the lungs, exocrine glands, bowel, kidneys and lungs
32
What determines which organs excretes a medication?
Chemical makeup
33
What is the 'half life' of a medication
The amount of time it takes for 50% of the medication to be eliminated from the blood stream
34
What is the therapeutic effect of a medication?
The intended/desired physiological response of a med
35
It is possible for a medication to have more than one therapeutic effect?
Yes, e.g. aspirin
36
What is an adverse effect of a drug
The unintended effect of a medication, either harmless or detrimental
37
What are 4 adverse effects of a medication?
- Side effect
- Toxic effect
- Idiosyncratic effect (unpredictable effect)
- Allergic reaction
38
What does a medication interaction mean?
- Occurs when one med modifies the action of another med
39
Can medication interactions include over the counter drugs
Yes
40
What can occur if there is a medical interaction
Can increase or diminish actions of other meds and alter absorption, metabolism or elimination from body
41
What is a synergistic effect mean?
When the combined effect of 2 meds is greater than the meds given separately
42
What is the goal when giving a medication?
To achieve a constant blood level of a medication within safe therapeutic range
43
How would we be able to maintain constant therapeutic concentration of a drug in bloodstream?
Regularly scheduled doses because a portion of drug is always being excreted
44
When should a medication be given to maintain constant therapeutic levels?
When previous dose reaches half life
45
What are the 3 time intervals of medication action? Explain each
Onset
Peak: max effect
Trough: the lowest amount of drug detected in system
46
What is a medication order?
A written direction given regarding treatment or medication
47
What are the 7 essential parts of a drug order?

48
As a student nurse, can you take verbal orders?
No
49
What is medication reconciliation?
The process of creating the most accurate list possible of all the med's a patient is taking
50
How does one do medication reconciliation?
By comparing patients list against health care providers order
51
What is the goal of medication reconciliation?
To increase patient safety by providing the correct medications to the patient at all transition points thus preventing adverse reactions
52
Where should medication reconciliation be implemented?
