| What labs/studies would you order to rule out particular causes of HTN | Renovascular AM/PM cortisol (cushing's R/O) CXR if suspicion of cardiomegaly Plasma aldosterone to R/O aldosteronism ECG Pa/lateral |
| BP treatment Recs | > or = 60 <150 SYS and 90 DYS < 60 <140 SYS and 90 Dys |
| What should you screen for before admin of thiazide diuretics? | sulfa allergy |
| electrolyte abnormality that can occur with thiazide diuretics | hypo K; hypo Na; hypo Mg; hyper Ca; hyperglycemia |
| Can Ca++ blocker be used as mono therapy? | NO |
| What do kersey B lines represent | interstitial edema |
| NYHA Class I HF | No limitations oh physical activity: normal activity does not cause S/S |
| NYHA Class II HF | Slight limitations oh physical activity but comfortable at rest; physical activity results in fatigue, palpations, dyspnea and agina |
| NYHA Class III HF | Marked limitations of physical activity but comfortable at rest |
| NYHA IV HF | Severe; inability to carry out any physical activity without discomfort with signs and symptoms at rest |
| Non Pharmacologic MGMT of HF | Na restriction Rest/activity balance weight reduction |
| Pharmacologic MGMT of HF | Ace inhibitors Diuretics Anticoag therapy in the setting of afib |
| Tx of Pulmonary | Provide O2 and acquire ABG semi fowlers position Morphine 2-4 PRN q20-30 stop if hypercapnia Lasix 40mg IV repeat in 10 minutes if no response |
| Your pt has pulmonary edema with bronchospasm what should you give | Inhaled sympathomimetics |
| your patient has severe pulmonary edema. What medications would reduce the afterload and preload | nitroprusside hydralazine |
| Your pt has pulmonary edema and there cardiac index is low what you would choose the following drug ________ | dobutamine 5-20 ug/kg/min |
| SE's of ACEIs | cough, rash, taste disturbances, hyperkalemia, renal impairment |
| First Line Tx for HTN | Thiazide diuretics |
| SEs of Thiazide Diuretics | Hypo K Hypo Mg hyperglycemia hypo Na Hyper Ca |

| Arterial vasodilators are used primarily as ___________ therapy | adjunct |
| SE or arterial vasodilators | reflex tachycardia, orthostatic hypotension, flushing dizziness |
| Decreased blood flow through the vessel causing tissue ischemia is | Angina |
| Stable angina | exertional; can be acute or chronic |
| Prinzmetal's angina | variant angina; occurs at various times to include rest |
| Unstable angina | pre-infaction, rest or crescendo, coronary syndromes |

| What factors is ASCVD risk based on? | Age Sex Race Total Cholesterol SBP DM status Smoking Status |
| What is the foundation of ASCVD prevention | heart healthy lifestyle |
| What groups with ASCVD would benefit from statin therapy | Those with clinical evidence of ASCVD Those with LDL-C >190mg/dl Diabetics 40-75 years of age w/ LDL-C between 70-189 w/estimated 10 year risk of 7.5 or higher |
| in the adult >21 but less than or equal to 75 years of age with clinical ASCVD ________ should be initiated | High dose stating therapy |
| High dose statin therapy medications would be | atorvastatin 40-80mg rosuvastatin 20-40mg |
| if high statin therapy is contraindicated or there are associated adverse effects then initiate _________ | Moderate statin therapy Atorvastatin 10-20 rosuvastatin 5-10 simvastatin 20-40mg pravastatin 40-80 fluvastatin 80mg |
| the goal of high intensity statin therapy is to | reduce LDL-C by 50% |
| S/s of MI | Feeling of impending doom syncope NV dyspnea cough cold weather/weakness |
| The physical exam of a patient undergoing an MI commonly reveals an S3 or an S4? | S4 |
| Peaked ST waves in I, aVL suggest | lateral MI |
| Peaked T waves in II, II, aVF suggest | inferior MI |
| peaked ST waves in V leads suggest | anterior MI |
| A first Degree AV block is indicated by | PR interval >0.20 sec |
| Type I second degree AV block (Wenckebach or Mobitz type I) is indicated by | PR interval gradually gets longer until a QRS complex is dropped |
