Chapter 11 Flashcards
psychopharmacology, dietary supplements, and biologic interventions (86 cards)
The following flashcards are going to be a mixture of study guide information and the powerpoint information that was provided
Before anything we always need to understand Maslow hierarchy, which are ?
- physiological needs
- security and safety
- love and belonging
- self-esteem
- self actualization
notes to read outloud
- Psychiatric medications are designated in certain conditions for specific symptoms.
- same symptoms may be present with different diagnoses.
- all medications have desirable and undesirable effects.
- nurses must understand these concepts to help ensure patient safety
notes to read outloud
target symptoms
- specific, measurable, expected to improve with treatment
- monitor and document effect of medication on target symptoms
- medications will affect more than just target symptoms resulting in wanted and unwanted side effects or adverse reactions
- nurse must document and report any side effects and/or adverse reactions
notes to read out loud
drug regulation and use
- FDA responsible for ensuring safety, efficacy, and security of drugs
- includes 4 phases of testing before approving new medication
- nurse must know labeling content before administering a medication
- muse be aware of any boxed warning and be alert for any appearance of the adverse reactions
notes to read out loud
psychopharmacology
- small amount of medication can have profound effect on individual
- each nurse must understand the basics to be able to provide the best clinical care possible
- pharmacodynamics
- Clincal concepts
- pharmacokinetics
something important to note that when a patient is receiving any medication, the medication is going to act on your receptors, mainly 2 types. what are the 2 types?
agonists
antagonist
what is agonists vs antagonists receptors ?
agonist
- same response
antagonists
- block response
within the receptors, we have selectivity, affinity and intrinsic activity.
tell me what each of these mean
selectivity
- specific drug for specific receptor
affinity
- degree of attraction or strength of bond between drug and biologic target
intrinsic activity
- ability to produce response after attaching to receptor
we understand that medications are a very important part of psychiatric-mental health nursing care.
- psychotropic medications work on different and various receptors in the brain as we mentioned before.
- they can inhibit the reuptake of the neurotransmitter or block the receptor
with this information, what can be ruled out if change in receptors, loss of receptors, exhaustion of neurotransmitter supply, increased metabolism of the drug or physiologic adaptation can cause what ?
explain this
decreased in medication effects
because our body either adapts/tolerance to the medication and or we simply dont work well with the medication
this flashcard is going to be asking about the defiention of each term.
Efficacy
Potency
Desensitization
Tolerance
Toxicity
Therapeutic index
ability to produce response
dose needed for effect
rapid decrease in drug effects
gradual decrease in drug action
drug concentration harmful to body
ratio to maximum nontoxic dose to minimum effective dose
Each route of administration has its advantages and disadvantages.
What are some examples of administration?
What is the best?
Oral, IV, IM, Topical
IV - fastest route
read out loud notes
pharmacokinetics
- first pass effect
- bioavailability
distribution
- size of the organ
- blood flow to the organ
- solubility of the drug
blood brain barrier
placenta
- plasma protein binding
- anatomic barriers
metabolism
- biotransformation
- cytochrome
excretion
- clearance
- half life
- can vary significantly to any individual ; must be alert to fluctuations and adjust dose and or schedule accordingly
The cytochrome P450 (CYP450) system plays a major role in drug ____?
metabolism
CYP450 is usually prescribed for what two types of medications?
antipsychotic
antidepressants
Several factors can affect the distribution, such as ?
dont overthink it
age
genetics
allergies
what are the 4 phases of drug treatment and nurses role ?
initiation
stabilization
maintenance
discontinuation
tell me what is going on with each phase
initiation
stabilization
maintenance
discontinuation
psychiatric evaluation
cultural beliefs & practices
physical examination
monitor patients respond to med
adjust or titrate medication dosage
patient education
patient care plan
therapeutic drug monitoring
target symptoms have improved
patient education
assist patient in process
some medications will be gradually tapered in dose to prevent recurrence or withdrawal
- some mediation will be needed for life
what does pharmacokinetics means?
including what 4 things
how the human body processes the drug, including absorption, distribution, metabolism, excretion
what does bioavailability mean ?
describes the amount of the drug that actually reaches circulation throughout the body
how does age affect drug absorption, distribution, metabolism and excretion?
gastric, renal, liver, parasympathetic functions/system are usually decreased with older ages
how does pharmacogenetics affect absorption, distribution, metabolism, and excretion?
genetic makeup can affect response to medication
(variations among ethnic groups)
what does ethnopsychopharamacology mean ?
and how does it affect absorption, distribution, metabolism, and excretion ?
cultural variations and differences influencing effectiveness
example ; asian descent produce higher concentration of acetaldehyde with alcohol use than do those of European descent
some cultures may not want to take the medications, and genetic makeup can mess up the actual helpfulness of the med
with medication use, it comes with side effects. its a no brainer that no matter how clean the medication can be, some patients will have side effects and some not. But not all side effects need to be treated with more medications, so as a nurse its important to what ?
know how/when to intervene when side effects need to be treated.
so like if dry mouth is an issue, tell them to drink more water, instead of giving them like a med for it
