25
beta2-adrenergic
used for asthma patients, classification that contains at least eight different medications
26
elixir form
clear fluid containing water and or alcohol, often sweetend
27
highly lipid-soluible medications
cross cell membranes easily and are absorbed quickly
28
Blood flow effects medication how
richer blood flow makes it easier for medication to absorb
29
membrane permeability
to be distributed to an organ a medication has to pass thorugh all of the the tissues anbiological membranes of the organe
30
blood-brain barrier only allows
fat-soluble medications to pass into the brain and cerebral spinal fluid
31
CNS infections require what type of trement
injection of antibiotics directly into the subarachnoid space in the spinal cord
32
albumin effect on medication
medications partialy bind to albumin making that part of the chemical not be able to exert is purpse but the parts that are not binded are free. older people have less albumin so they are at more risk for toxicity
33
biotransformation
occurs under the influence of enzymes that detoxify and remove biologically active chemicals, most biotranssformations occur in the liver
34
exocrine glands help eliminate what
excrete lipid soluble medications
35
therapeutic effect
the expected or predicted physiological response to a medication
36
naloxone
an opioid antagonist, reverses the effects of opiod toxicity
37
idiosyncratic reaction
medications sometimes cause unpredictable effects
38
medication interaction
one medication modifies the action of another
39
synergistic effect
the combined effect of two medications is greater that he effect of the medications when given separately,
40
Alcohol is synergistic with
antihistamines, antidepressants, barbiturates, and narcotic analgesics
41
patient with high bp can take
diuretics and vasodilarors that act together to control the blood pressure when one medication is not effective on its own
42
trough level is generally drawn how many minutes before administering the drug
30 minutes
43
the peak level is drawn whenever the drug is
expected to reach its peak concentration, this varies depending on the medication
44
time critical medications
within 30 minutes before or after scheduled administration time
45
non time critical medications are given
1 to 2 hours before or after scheduled time
46
parenteral administaration
involves injecting a medication into body tissues
47
four major sites of injections
1. intradermal (ID): injection into the dermis just under epidermis 2. Subcutaneous: injection into tissues just below the dermis of the skin 3. Intramuscluar 4. Intravenous
48
polypharmacy
happens when a patients takes two or more medications to treat the same illness
49
allopathic medicine
conventional western medicine
50
diffusion
passive movement of electrolytes or other particles down the concentration gradient
51
reflex incontinence
damage to the spinal cord above the sacral reginion, causes loss of voluntary control of urination
52
uremic syndrome
an increase in nitrogenous wastes in the blood, marked fluid, and electrolyte abnormalities, nausea, vomiting, headache, coma, and convulsions are all characteristics
53
renal replacement therapies
used when the uremc symptoms worsen, need it for survival
54
hyperactive or overactive bladder
associated with indivauals of all ages, but older adulsts are more likely to have incontinence associated with it following physical and cognitive decline, occurs from sudden involuntary contraction of the muscles of the urinary bladder
55
sudden contractions of the bladder muscles causing need to void
urge incontinec
56
nephrostomy
urinary drainage directly from one or both kidneys, tube is placed directly into the renal pelvis
57
three pressure related factors contribute to pressure ulcer develpment
pressure intensity, pressure duration, and tissue tolerance
58
risk factors for pressure ulcer development
impaired sensory perception, impaired mobility, alteration in level of consciousness, shear, friction, moisture
59
stage I pressure ulcer
nonblanchable redness of intact skin,
60
stage II
partial thickness skin loss or blister, presents as shiny or dry shallow ulcer without slough or brusing
61
stage III full thickness skin loss
subcutaneous fat may be visible but nothing else, slough may begin to be present along with tunneling
62
stage IV full thickness
exposed bone, tendon, or muscle, slough or eschar may be present, tunneling is common
