Nursing Therapeutics Flashcards
Therapy
the tx of the disease or disorders as by some remedial, rehabilitating or curative process
Anthropometry
height and weight of the person
Considerations around weight
done daily @ same time (morning)
Serum proteins
- Biochemical analysis -
nutritional status, liver function
affects level of proteins that liver produces, blood loss
Albumin
- Biochemical analysis -
most common serum protein
longest half life
good snap shot of a person’s nutritional status
Transferrin
- Biochemical Analysis -
protein that transports iron, body increases transferrin if iron deficiency
Transthyretin and retinol binding protein
respond to changes to nutrition quickly, affected by many factors
not best lab test to trend
C reactive protein
indicator of infection and inflammation
source of metabolic stress
leads to increased nutrition
Usual/ideal body weight
provides an estimate of what a person should weigh and rapid weight gain would indicate fluid shifts
usual is more affective than ideal body weight for changes in obese, underweight, or overweight
Therapeutic index
measure of the safety of the drug ratio of the lethal dose of a drug and the minimum dose at which a therapeutic affect occurs
narrow: 1-2; difference b/w lethal dose and therapeutic dose is small
- more critical to assess -
Large: 4-5; difference is large
Potency
relative amount of a drug required (in comparison to other drugs of the same class) to produce a desired response
Higher potency = lower dose
Efficacy
measure the amount of the magnitude of maximal response in the patient that can be produced by a particular drug
lower dose (does not equal) decreased side effects
Drug actions
mechanism of drug actions in living tissues
- receptor interactions
- enzyme interactions
- nonspecific interactions
Drug effect
the physiologic reaction of the body to the drug
potency and therapeutic index
acute therapy
ICU or trauma rooms
ex. high risk meds in controlled environments
