N211 -Health Differences Across the Life Span 1 Flashcards
HTN
28-31% adults in US
of this , 90-95% PRIMARY HTN (unidentified cause)
remaining 5-10% SECONDARY HTN (identified cause)
Identified Causes for HTN
-narrowing renal arteries, renal parenchymal dis, hyperaldosteronism (mineralocorticoid HTN), Pregnancy, coarctation of aorta, certain meds
ETOH and HTN linked to
UP triglycerides, sugars, weight gain, LDLs, cardiac function
Dx someone with HTN elevation on one round. Must have average of
2 or more contacts w health care provider
Normal BP
<120/<80
Pre HTN
120-139/80-89
PIH (pregnancy induced HTN usually resolves after placenta expelled)
Stage 1
140-159 / 90-99
Stage 2
160 up / 100 up
Stage 1 TX
Medication, MD until stable
Stage 2 Tx

HTN Crisis Tx.
Short lived meds (minutes - 4hrs)
Nitroglycerin (Nitro-Bid)
Socium Nitroprusside (nipride or nitropress)
nicardipine hydrocholoride (cardene)
enalaprilat (vasotec)
Vasodilator: Fendolopam
Fendoldopam (Corlopam)

Alpha Adrenergic Clocker
WORK DIRECTLY ON BLOOD VESSELS
keeps hormone from tightening muscles and walls. counter epi and nor epi.
SE: V/N/D, urinary freq, cardio vascular collaps

SE: V/N/D, urinary freq, cardio vascular collaps
Beta Adrenergic Blocker
COREG
ALPHA and BETA
Dry Cough - BAD, change meds
Slow transition to get used to
SE: cardiovascular. can worsen ss. not for newly HTN patients Not first line drug.
Contracindicated in Heart failure, COPD and ?
Beta Adrenergic Blocker: Inderol
Propanolol
for Stage Fright, BP control,
slows HR, reduces cardiac output, fatigue, bizarre dreams
SE bradycardia, insomnia, fatigue,
Calcium Chan Blocker
Diltiazem
Inhibit calcium ion influx and reduce after load.
inhibit na, inhibit water.
Procardia: CHF, resistant Angina,
Some people chew to get emergency fast effects. not for normal pt as it can bottom out pressure fast.
Beta Adrenergic Blocker
Lopressor, Corguard, Inderol, Toprolol
slow HR. they get breathless, can’t excercise on this drug.
decrease contractions and AV signal,
SE bradycardia, insomnia, fatigue, bad dreams, sex dysf, LO HDL, GI probs, LO BP, depresson
ACE Inhibitors
Angio 1 - 2.
lowers resistanece of peripheral vascular syste =less risistance
SS proteinurea, dry cough, hyperkalemia, renal damage
Catapress
Aldamet
diminish periphera outflow from brain. brain action to neurons.
dose at bedtime. monitor 30-90min for syncopy
Diuretics
Thiazides
pulling fluid from extra vascular to intra vascular spaces to rebalance lo plasma.
affect smooth muscle.
Burn patients
hi K levels. As they stabilize, K drawn back into cells.
Loop Diuretics
can cause volume depletion . NOT first line. After Thiazines tried.
K sparing Diurents
can cause Hyper Kalemia.
Vasodialiators
Hydralazine
Hydralazine (Apresoline)
DASH Diet
reduce cholestoerol in blood

PTT (partial prothrombin time)
eficacy of Heparin
PT(C) (prothrombin time)
Efficacy of Coumadin
when we have a venus problem, DO NOT add heat
it will increase circulation. If arterial problem, yes warm. you want blood to go down to extremeties. in venous, the blood is pooling and we need to elevate legs to help move up blood.
intermitent caudicatoin
when person walks, not enough blood flow to legs. sever pain, heavy , sharp.
they stand still , then it goes away, then it starts again when they walk
Abdominal Aortic Aneurysm
-asymptomatic
Watch for
clotting
emboli
rx for clotting
SS:
Abdominal pain, low back pain, feel heart beat
Assessing AAA
Bruit, swooshing over consicted artery.
Pain: abdominal/loabdomin
Calcium Channel Blockers
Tx Angina, HBP
affect movement of ca in cells of heart
Digoxin/Linoxin
stronger heart contraction
Beta Blockers
Control catacholoamines

Pulse Pressure
diff between top and bottom
Pump Problems
cardiomyopathy
Cardiogenic shock
loss of hearts ability to pump enough blood to heart
hypovolemic shock
loss of large amount of blood or fluid
Distributive Shock
loss of vascular tone causing decreased peripheral resistance, larger vascular bed, result in hypovolemia
Class 3

Problems of intake and supply of O2
.
beta blockers
Inderol?
non selective vs selective
classic angina comes from
exertion or stress
unstable angina pre infarction
frequent times daily with increasing severity
classic dysrythmias result from
hypoxia and hypercapnia
Digitalis preps effective in treating
CHF
cardiac glycoside aka
dig glycoside
digitalis
allows heart to work less but beat stronger

Acute Respiratory Acidosis
inadequate excretion of CO2 w inadequate vent
Chronic Resp Acidosis
occurs w pulmonary diiseases
Nursing Interventions

HCO3 is Bicarb not H2CO3
when you rae chronically aciic, hi CO2
body become used to it. It’s stops becoming the hi CO2 that makes the breath, but the lo O2 levels.

Respiratory Alkalosis
Carbonic Acid deficit
.body loses CO2, decrease in acid, increases ph level
.occurs w hyperventilation, leads to loo CO2

Factors Causing Hypertension
.INcreased Sympathetic stimulation
.UP blood volume d.t increased renal reabsorption of Na+, CL- and H2o retention
.UP activity of RAAS system, caused expansion of extracellular fluid volume. causing systemic vascular resistance
.Dysfx of vascular endothelium causing decreased vasodilation of arterioles
.resistance to Insulin
