Toxicology Flashcards
1
Q
Definition: Toxicology?
A
= the study of abnormal physical states caused by drugs
2
Q
Definition: Pharmacodynamics?
A
= HOW the drug affects us
3
Q
Definition: Pharmacokinetics?
A
= WHERE the drug goes and how it gets there
4
Q
Definition: Drugs
A
- a chemical that has a physiological effect on the body
5
Q
Definition: Tolerance
A
- need for more after long-term use to achieve an effect
6
Q
Definition: Habituation
A
- taking drugs is part of routine
7
Q
Definition: Dependence
A
- the physical need for a drug to function normally
8
Q
Definition: Addiction
A
- the psychological desire to take drugs despite recognizing negative consequences
9
Q
Definition: Idiosyncrasy
A
- basically an uncommon side effect or reaction
10
Q
Definition: Synergy
A
- comes in two forms:
1. Summative = simple adding of effects
2. Potentiation = achieving a greater effect than the sum of the drugs
11
Q
SBVAC Drug Classification
A
- Name = Full name of drug
- Indication = Conditions we need to administer the drug
- Contraindications = Conditions that make us immediately unable to give the drug w/o Med Control
- Route = How we get the drug into the patient
- Dose = How much of the drug we give at one time, and how many times we can give it
- Mechanism = The actual physiological effect of the drug on the patient
- Side Effects = Possible common reactions to the drug
12
Q
Routes of Administration
A
- Enteral = passing through the epithelium of the GI tract (oral, buccal)
- Parenteral = Bypassing the skin and GI tract (IV, IM, IO, Subcutaneous)
- Absorbed (buccal, nasal, inhalation, transdermal)
13
Q
6 Rights of Drug Administration
A
- Right Patient
- Right Drug
- Right Dose
- Right Route
- Right Time
- Right Documentation
14
Q
BLS Drugs
A
- Aspirin, Albuterol, Epinephrine, Glucose, Naloxone, Oxygen
15
Q
Peer-Assisted Drugs
A
- Nitroglycerin, MDI’s, Possibly Epinephrine
16
Q
Definition: Agonist
A
- something that increases function at postsynaptic cell
17
Q
Definition: Antagonist
A
- something that decreases or blocks function at postsynaptic cell
18
Q
Receptors
A
= keys to cellular response
19
Q
Adrenergic Receptors
A
- receptors targeted by Catecholamines (Sympathetic)
- a1 = central vasoconstriction (Increases BP)
- B1 = increases HR, Myocardial Contractility, Blood Volume, and Blood Pressure
- B2 = Bronchodilation and increases glucose production and uptake
