Question
Answer
BP=   CO x PR  
CO=   HR x SV  
Hypertension can result from   change in cardiac output, change in peripheral resistance or both  
What happens to the BP if the vessels constrict?   Bp goes up  
What happens to the BP when the vessels dialate?   BP goes down  
Fluid retention and vasoconstriction does what to BP?   Raises BP  
What is a normal BP?   120/80  
What is prehypertension BP?   systolic 120-139, diastolic 80-89  
When a pt is in the prehypertension stage what is reccomended to help the pt.?   Lifestyle changes  
What is the pt.'s BP if the pt. is in stage 1 Hypertension?   Systolic 140-159, Diastolic 90-99  
What is the pt.'s BP if the pt. is in Stage 2 Hypertension?   Systolic greater than or equal to 160, diastolic greater than or equal to 100  
What % of Adults age 18 and older in the US have normal BP?   54%  
What % of adults 18 and older in the US have prehypertension?   22%  
What % of adults age 18 and older in the US have Hypertension?   24%  
Isolated systolic hypertension is more common in   older adults  
What happens as we age that causes increased preipheral resistance?   decrease in the elasticity of the major blood vessels, which causes increased bp  
What is Hypertension know as?   The silent killer  
When there is an increase in BUN and creatinine what does that tell?   That the kidneys are being damaged.  
Alterations in vision or speech, dizziness, weakness, a sudden fall, or temporary paralysis on one side of the body are clinical manifestations of   CVA or TIAtransient ischemic attack) , Stroke  
CVA   cerebrovascular accident  
Blood volume drops what happens?   BP drops, Heart Rate increases.  
What is Peripheral resistance?   How hard the blood has to pump through the arterials.  
What could be the outcome of Endothelial dysfunction?   Damage to the inner layer prevents blood vessels from dialating, causes vasoconstriction, leads to target organ damage. Atherosclerosis, Nitric acid release inhibited.  
When nitric acid relase is inhibited it causes   Vasoconstriction  
Pt.s should not ingest caffeine or smoke cigarettes for at least how many minutes prior to an office visit where their BP will be measured?   30 minutes  
A pt. should sit quietly for five minutes with arm at heart level prior to what?   Having their bp taken.  
How long should the nurse wait between taking BP if the need arises to take it again?   Two minutes  
If protein is found in the urine it indicates damage to what organ?   The kidneys  
What is an Echocardiogram   ultrasound of the heart  
How do you treat Prehypertention?   lifestyle changes  
What is the first med. given to lower blood volume   Thiazide Diuretics which lowers bp  
What happens when over diuresis happens?   BP decreases b/c too dehydrated  
What are the nursing considerations when giving a diuretic?   Give early in the day, watch for orthostatic Hypotension, Over diueresis = dehydration. If pt has kidney damage teach to watch for K+ and Na substitutes.  
What is the difference between the Thiazide and loop diuretics compared to the potassium sparing diueretics?   Watch for HYPOKalemia in Thiazide and Loop and Watch for HYPERKalemia in potassium sparing  
If pt. has kidney damage what should the pt. watch?   Salt subsitutes.  
What is an adrenegic peripheral agent?   Reserpine ( Serpasil)  
What med. can cause constriction, but is supposed to dialate?   Inderal  
what is the function of adrenergic agents ?   ANS controls involuntary functions of the body such as heart rate pupil size and smooth muscle contraction, including in arterial walls  
What are the side effects of adrenergic agents>   Orthostatic Hypotention, dizziness, nausea, bradycardia, dry mouth, impotence, bronchoconstriction  
When giving a pt. beta blockers what should you listen for?   crackles  
Beta blocker thearapy can mask what s & s in diabetics?   Hypoglycemia  
What meds are usually given in crisis b/c very potent?   Vasodialators  
What is a serious side effect of Vasodialators?   Reflex Tachycardia, be careful watch BP  
What are Ace inhibitors used to treat?   hypertension, HR, HFand MI  
Which drugs usually end in PRIL?   Ace inhibitors  
Persistant coughing, postural hypotension and angioedema are side effects of what drugs?   ACE INHIBITORS ( The Prils)  
The Angiotension II receptor blockers end in?   sartan  
What does the ARB's ( angiotensin II receptor blockers ) do?   Blocks the action of the angiotnsin II after it is formed  
What is the function of angiotension II>   increase BP causes vasoconstriction  
What is the difference between the ace inhibitors and ARB's?   ace inhibitors stop angiotension from being formed. ARB's block the angiotension II from binding to the receptors.  
What is the side effect of ARB's?   Hypotension  
What do the nondihydropyridines act on?   heart and blood vessels  
What do the Dihydropyridines act on?   blood vessels only  
Which calcium channel blocker reduces MI contractility and can worsen HF?   The nondyhidropyridines because they can affect the heart.  
What is contraindicated with Calcium channel blockers?   Grapefruit juice b/c it increase the absorption which causes greater than expected effects from the dose.  
Do NOT D/C BP meds without Dr.'s order b/c of?   rebound hypertension  
What complications would you look for in pt.s with hypertension>   Check eyes and kidneys  
What is a hypertensive crisis?   a hypertensive emergency and urgency  
What should be done in a hypertensive in a hypertensive EMERGENCY?   BP must be lowered immediately to prevent target organ damage  
What should you do in a hypertensive URGENCY?   Lower the BP within a few hours
