| what race is at higher risk for HTN? | AA and Indians |
| what is peripheral vascular resistance? | vessel constriction or dilation, which is controlled by autonomic nervous system and the hormones--epinephrine and norepinephrine |

| what do beta blockers do? | they block beta receptors in the heart and peripheral vessels, this reducing cardiac OP and BP |
| regulates perfusion of tissues at a constant level | vascular autoregulation |

| what are 2 types of K-sparing diuretics? | spironolactone (aldactone) and trimterene (Dyrenium) |
| what is arteriosclerosis? | the thickening or hardening of the arterial walls |
| normal BP range | <120 S---<80 D |
| what is the result of Ca channel blockers? | vasdilation and decrease BP |
| what are 2 adverse side effects of ARBS? | angioedema (caused by Candsarten and telmisarten and losarten can cause heart failure |
| what do angiotensin II receptor antagonists (ARBS) do? | they block the binding of angiotensin II in the VASCULAR and ADRENAL tissues...so basically they prevent angiotensin from doing its job |
| what Ca channel blocker increases the effects of Digoxin? | Nicarpidine (Cardene) |
| Photosensitivity is a side effect for which Ca Channel blocker? | Amlodipine (Norvasc)--use protective clothing |
| beta I is used for ___ | cardiovascular---common with HTN |
| what are the signs of hyponatremia and hypokalemia? | irregular pulse and muscle weakness |
| what do angiotensin converting enzyme (ACE) inhibitors do? | they inhibit the conversion of angiotensin I to angiotensin II---basically they are preventing the vasoconstriction that angiotensin II produces |
| beta II is used for ___ | lungs |
| is released from the adrenal glands and its function is to retain Na | aldosterone |
| what do loop diuretics do? | they depress Na reabsorption in ASCENDING LOOP OF HENLE and promote K excretion---basically they get rid of water, Na, and K |
| which HTN drugs are used to prevent kidney disease? | ARBS and ACE |
| what is a beta blocker drug? | "OLOL" DRUGS---propranolol (inderal) |
| what is the strongest diuretic? | loop diuretics |
| what diagnostic assessment shows left artial and left ventricular enlargement? | x-ray and ECG |
| beta nonselective is used for ____ | both heart and lungs = heart rate, BP, and respirations all DECREASE |
| pre-HTN BP range | 120-139 S---80-89 D |
| what is the least potent diuretic? | thiazides |
| what are 2 types of loop diuretic? | furosemide (Lasix) and Bumetamide (Bumex) |
| what increases CO? | increased heart rate and increased blood volume |
| what are the risks of taking aldosterone receptor antagonists? | hyperkalemia and hyponatremia |
| what do thiazides do? | they prevent Na and water reabsorption in the DISTAL TUBULES and promote K excretion---so basically they help get rid of water, Na, and K |
| what are 3 types of diuretics? | thiazides, loop, and K-sparing |
| increase in Na and water = ____ in BP | increase |
| if there is a rise in artial pressure (BP), the ___ nerve will be stimulated, which will cause a decrease in ____ and _____ | vagal nerve.....decrease in heart rate and vasodilation |
| if taking Ca channel blocker Dilitiazem, avoid ____ and why? | grapfruit juice bc it increases the drug level and will further decrease BP |
| increase in cardiac OP = increase in blood to kidneys = ___ dieresis that leads to ____ in BP | increase dieresis and decrease BP-->this occurs if there is normal kidney function |
| what are some common signs of HTN? | HA, dizziness, or fainting |
| if a pt has a BMI ___ or higher weight loss is encouraged | 25 |
| what should be monitored on a pt taking a beta blocker? | fatigue, weakness, depression, sexual dysfunction all due to lack of O2 |
| what is a stroke volume? | amount of blood ejected from the heart per beat |
| what increases peripheral vascular resistance? | factors that increase blood viscosity (such as dehydration) and factors that decrease vessel diameter (such as caffenine, nicotine, meds) |
| what do K-sparing diuretics do? | they act on DISTAL TUBULE to inhibit Na reabsorption in exchange for K, thereby retaining K---so basically they get rid of water and Na and keep K |
