Flashcards in test 5 Deck (49):
high blood pressure associated with renal, pulmonary, endocrine, and vascular diseases is known as what?
elevated systemic arterial pressure for which no cause can be found is known as what?
idiopathic hypertension (essential or primary)
the primary effect of these drugs is to decrease plasma and extracellular fluid volumes
theses drugs are used in the management of hypertensive emergencies
drugs that are often used as first-line drugs in the treatment of both heart failure and hypertension are known as
adverse effects of ACE inhibitors
fatigue, headaches, dry cough
a patient is being treated for a hypertensive emergency. the nurse expects to administer what drug?
sodium nitroprusside (Nitropress)
which antihypertensives are considered more effective in white patients?
beta blockers and ACE inhibitors
which antihypertensives are considered more effective in african americans?
calcium channel blockers and diuretics
what is the purpose of abtianginal drugs
to increase blood flow to ischemic cardiac tissue
common adverse effect of nitroglycerine (Nitrostat)?
patients who are taking beta blockers for angina need to be taught what?
these drugs are for long-term prevention of angina episodes
a patient with coronary artery spasms will be most effectively treated with which type of abtianginal medication?
calcium channel blockers
what lab work should be monitored with ACE inhibitors
what is the relationship between digoxin and potassium levels
low potassium levels increase the change of digoxin toxicity
when caring for a patient who is taking digoxin, the nurse will monitor for which signs and symptoms of toxicity?
anorexia, visual changes, nausea and vomiting, headache, bradycardia
what laboratory tests are a priority when starting ACE inhibitor therapy
serum potassium levels, creatinine level, BUN
decreased heart rate
slows conductions of electrical impulses
lidocaine infusion could be used for what disorder
adverse effects of quinidine (Quinidex)?
GI upset; tinnitus; ventricular ectopic beats
adverse effects of amidarone (Cordarone)
verapamil (Calan) is used to treat what?
recurrent proxysmal supraventricular tachycardia (PSVT)
how should adenosine (Adenocard) be given?
fast IV push
if a drug has a prodysrhythmic effect, then the nurse must monitor the patent for which effect
a drug that prevents the lysis of fibrin, thereby promoting clot formation
the rumination of bleeding by mechanical or chemical means
a substance that prevents platelet plugs from forming
anti platelet drug
the general term for a drug that dissolves a thrombi
a laboratory test used to monitor the effects of drug therapy with warfarin sodium
prothrombin time (PT)
international normalized ratio (INR)
a standardized measure of the degree of coagulation achieved by drug therapy with warfarin sodium
international normalized ratio (INR)
a substance that reverses the effect of heparin
a substance that reverses the effect of warfarin sodium

patients taking cholestramine (Questran) may experience what adverse effects?
belching and bloating
the nurse will instruct the patient taking antilipemic drugs about what dietary measures?
take fat soluble vitamins
increase fluid intake
choose foods that are low in saturated fats and cholesterol
increase the intake of raw veggies, fruits, and bran
what is good cholesterol
possible side effects of iron supplements
nausea, vomiting, stomach cramps
action of ACE inhibitors
inhibit the conversion of angiotensin 1 to A2
what do we ultimately decrease with ACE inhibitors
preload and after load
central acting alpha 2 receptor agonist
**high incidence of 1st dose hypotension
short half life (need 2xday)
**not a prodrug-ready to GO!
not a prodrug-- ready to GO!!
can be combined with a diuretic
ACE inhibitors drug interactions (5)
NSAIDs; other ACE inhibitors; lithium; potassium supplements; potassium sparing diuretics
first dose hypertension; dry cough; potassium retention; renal failure; angioedema
blocks receptors for angiotensin; causes vaso/arteriol dilation
