37
What are the 3 physiological factors that influence blood pressure
Cardiac function / pumping of heart Peripheral vascular resistance Blood volume
38
Cardiac function Stroke volume: Cardiac output:
Stroke volume : quantity of blood flowing out of the left ventricles with each contraction Cardiac output: the volume of blood pumped by the heart per minute Co = sv times heart rate
39
Increase in co
The heart’s pumping action is strong and the volume of blood pumped into circulation increases Condition that increase co causing increase bp Increased blood volume as occurs during pregnancy, fluid retention More forceful contraction of the ventricles as occurs during exercise
40
Decrease in co
The pumping action of the heart is weak Less blood is pumped into the arteries Causes decrease in bp *conditions that decrease co include Dehydration Active bleeding Damage to the heart
41
How does the vascular resistance effects the diastolic pressure causing increase in bp
Blood viscosity Arterial size Arterial compliance ( elasticity) Blood volume : Increase blood volume increase in blood pressure Decrease blood volume decrease bp

Generic name Trade name Route Classified Indication Therapeutic action/goal
46
What is pharmacokinetics 4 phases ( Adem)
Metabolism: how it’s broken down, Absorption : how will it get inside ( drug dose drug form, blood flow site and condition of absorbing surface ) Distribution: where will it go ( transport ) Excretion: how fast it leaves ( lungs gi breast milk saliva and feces )
47
Principles of med admin via gi tube
Elevate head of pt bed Check placement , residual and patency Use liquid meds when possible When crushing meds ensure they are okay to be crushed ( no capsule or sustained release meds After feuding mix one medication at a time with 15-30 ml of water and give each medication one at a time Flush tube with 15-30 ml water before and after each administration

49
What are complications with distribution?
The availability can be limited by the body through barriers, blood /brain Barrier and placenta Drug that binds with plasma protein can be prevented from immediately reaching tissue
50
Metabolism
Biotransformation of drugs Mainly done by liver Enzymatic effects cause drugs to be changed into a form more easy to excrete P450 is one of the primary enzymatic pathways in the liver for drug transformations First pass effect : most oral med experience this by going directly through propel circulation, inactivating much of a drug
51
Excretion
Process of removing the drug or it’s metabolites form body Done primarily by kidneys Renal impairment = decreased excretion of the medication and increase risk of toxicity Poor kidney function requires low speeded of many meds
52
What is pharmacodynamic
The process by which drugs alter cell physiology and effect the body, these processes include: Receptor agonist ( actives ) Receptors antagonist ( blocks) Drug enzymatic actions
53
Therapeutic drug actions
Occurs by maintaining constant drug level in body Half life : expected time for the blood concentration to measure one half of the original doe due to elimination
54
What is the therapeutic range
Serum level of concentration of the drug that produces desired effect without toxicity Onset of action: time takes body to respond after administer Peak : highest plasma concentration Trough: lowest plasma concentration
55
Elder consideration
Altered memory Decreased visual acuity Decrease in renal function Slow absorption from the gi In creation proportion of fat to lean body mass Decreased liver function decrease organ sensitivity Altered quality of organ responsiveness Decrease in manual dexterity
56
What are side effects vs adverse
Predictable but unwanted, sometimes unavoidable reactions to meds Adverse : severe unwanted unpredictable drug reaction May occur after 1 dose ( sever allergic response ) May occur over time ( eg anemia ) Allergic reaction: unpredictable immune response , rash hives runny nose Anaphylactic reaction: severe allergic reaction and a medical emergency
57
Adverse drug cont.
Some can be predictable and manageable (side effects ) Others more serious allergy ( anaphylaxis) toxicity Drug tolerance, drug to drug interactions and idiosyncratic effects are also possible adverse effect
58
Toxic effects:
Results form medication overdoes or buildup in the blood due to impaired metabolism and excretion
