propanolol-
bromchocontriction
hypotension
bradycardia

35
Q

Include considerations and implications of using autonomic nervous system drugs across the lifespan

A

As patients get older, they are going to need bp and other vital sign medications more. Also with decreased metabolism it will sit in system for longer

36
Q

Include evidence-based concepts when using the nursing process related to medications that affect the autonomic nervous system

A

Asess-many type of medications stimulate or inhibit specific ANS receptors- assessing which ones will help specific problems

Plan-
atient will adhere to the drug regimen.
Patient’s vital signs will be within the desired range

implement- give drug. make sure to give medications when patient is right

evaluate- document wether patient is doing as well an presribed

37
Q

L
Provide examples of the scheduled categories for controlled substances.

1- no accepted medical use

2-high potential for abuse

3-low potential for dependance

4-low potentialfor abuse

5-lowest potential for abuse

38
Q

A

to establish a legal framework for the safe and effective distribution of prescription drugs

39
Q

Step 1: Discovery & Development.

Step 2: Preclinical Research.

Step 3: Clinical Drug Development Process
.
Step 4: FDA Review.

Step 5: Post-market Monitoring.

40
Q

Analyze the ethical aspects of medication administration.

A

always work for the patent and fight for their right no matter where they are

41
Q

Explain the effect of socio-cultural factors in regard to a patient’s response to and compliance with medication therapy.

A

Patients with strong belief in the harm of medications were found 4 times more likely to have poor medication adherence than those with weak belief in the harm of medications

nurses need to have knowledge of all culture and beliefs. some cultures and beliefs don’t allow certain types of medications

42
Q

Summarize the nurse’s role in educational management of medication therapy.

A

Nurses need to explain side affects and adverse affects to the patient. This allows for patient education so the patient knows what will happen to their body when they take the drugs

43
Q

Explain the relationship between plasma concentration and half-life of a medication.

A

Half-life (t1/2) refers to the time required for plasma concentration of a drug to decrease by 50%

44
Q

Differentiate among adverse medication reactions: side effects, toxic effect, allergic reaction, idiosyncratic reaction, and teratogenic reaction.

A

Side affects- non inteefdned affects- can be predictable

toxic afects- its ability to cause harmful effects

ido-an abnormal susceptibility to a drug peculiar to the individua

terat-drug is a teratogen if its administration to the pregnant mother, directly or indirectly,

45
Q

Compare the action of agonist and antagonist medications.

A

agonist-work with the receptor-stimulate

antagonist-work againts-inhibit

46
Q

Identify the significance of the following terms in the measurements of medication concentrations in the body: minimum effective concentration (MEC), minimum toxic concentration (MTC), plateau or steady-rate concentration, peak concentration, and trough concentration.

A

MEC- is the minimum plasma concentration of a drug needed to achieve sufficient drug concentration at the receptors to produce the desired pharmacologic response,

MTC- represents the minimum blood level at which a toxic effect occurs

plateau C-At steady state, the amount of drug administered on each dosing occasion is matched by an equivalent amount of drug leaving the body between each dose.

Pc–when drug is highest in blood

t-when blood is lowest in blood

47
Q

Compare the significance of the chemical name, generic name, and brand name of a medication.

A

Chemical name-they tell us about the elements present

generic name-generic names are a shorthand version of the drug’s chemical name, structure, or formula- all the same

brand name-brand names are usually catchy, often related to the drug’s intended use, and relatively easy to remember

48
Q

Discuss the process of pharmacokinetics

A

absorption-Occurs when a medication enters the body and travels from
site of administration into the body’s circulatio

distribution-Movement of the drug within the body (blood/plasma to intra/extracellular compartments)

metabolism-Breakdown of drugs so they can be eliminated more easily

excretion-Process of elimination of waste

49
Q

Describe the process of pharmacodynamics

A
  • Agonist
    Activates receptors
  • Antagonist
    Blocks receptor

Therapeutic window
Peak drug level
through level
therapeutic index

50
Q

Consider pharmacodynamic differences across lifespan

A

target cell sites and changing numbers of protein receptors. Immature systems and changing body compositions mean that drugs affect children differently.

body composition, immature systems, and genetics. Total body water, fat stores, and protein levels change throughout childhood and greatly influence the effectiveness of drugs in the pediatric population.

As you get older. your body has less to fight off the drug with, so it will stay in system for longer

51
Q

Differentiate among prescription drugs, over-the- counter drugs, herbals, and dietary supplements

A

OTC

-Do not require a prescription
* Regulated through FDA
* Prescribed meds may be available OTC in smaller doses

Dietary-
Includes vitamins, minerals, enzymes, and botanicals
* Not regulated by FDA

Prescription

-requires perscriprion
regulated FDA
larger doses
need doctor order
