hey guys nurse Mike here and welcome to simplenursing.com now before we get today's lecture started please remember to access your free quiz and preview our cool Nifty new study guides not here on YouTube click the link right up here at any time during this video all right guys let's begin pharmacology always an enlex favorite here guys we took over 10,000 enlex questions and organized only the most testable stuff here for you so the content you see here is the content you need to pass okay now our main goal here is to drain that fluid and help the heart pump blood forward so pause your screen and write these names down please focus on the ending of the drugs since the enlex focuses on this they expect you to know what the drug does and how it can kill or harm the patient which we'll cover right after this now all these drugs drop the blood pressure and take workload off the heart except dioxin AKA dig jockson who digs for a deeper contraction it does not affect the blood pressure at all it only decreases the heart rate and he comes with toxic side effects so we call dexin the toxin so the big enlex tip here is everyone here can cause orthostatic hypotension or low blood pressure and dizziness when standing everyone except diin since it does not affect the blood pressure so we teach enlex key terms here write this down slow position changes when blood pressure is low we got to go slow big on the enlex trust me guys they will try and trick you so let's break these down one by one first up a is for ACE inhibitors and arbs who act to lower the blood pressure only guys not the heart rate big on the enlex our first choice is ACE inhibitors that end in p like linil so we call it a chill pill for the heart we're talking low blood pressure not the heart rate or think pills puts the blood pressure low now our second choice is arbs the Angiotensin receptor blockers which end in stin like low sartin so think sartan like relaxed man or retirement plan lowers the blood pressure not the heart rate so a question for you do we give pills and sartin if the heart rate is bra cardic or below 60 well guys yes ACE inhibitors and arbs act to lower the blood pressure only not the heart rate so we only hold for low blood pressure now the mechanism of action is quite simple both Aces and arbs either inhibit or block the Raz system which retains fluid or in fancier terms the renin Angiotensin aldosterone system so aldosterone is blocked from adding that sodium water in and letting that potassium out so again the big problem here is retaining too much potassium huge side effect now speaking of side effects we just keep it simple so just think Ace like an Ace inhibitor a for avoid pregnant patients these two are baby toxic a for angio edema swelling of the face and tongue resulting in a huge Airway risk very deadly but guys this only happens with ACE inhibitors so just think pills puff up the tongue and not sartins big enlex tip now C is for cough but again only prills do that and E is for elevated potassium not vitamin K we're talking potassium over 5.0 so think p and pills Puffs the tongue and adds potassium and S is for sartins sartins spare the potassium and are prescribed second after Aces now we teach patients to avoid potassium rich foods like fruits and veggies specifically green leafy veggies avocados melons and oranges but even salt substitutes and liver now I didn't know the liver one until we did the enlex review now a quick enlex side note since potassium pumps the muscles early signs of high Potassium we're thinking High pumps of the muscles so key word here is muscle spasms so with our ECG we have high pumps with Peak t- waves and St elevations and any potassium imbalance high or low always the first action by the nurse is cardiac monitor huge enlex favorite right there so again PRS and sartin are Aces and arbs remember the Three A's a for anti-hypertensive we're talking low blood pressure not heart rate so slow position changes a for avoid pregnant patients not baby safe and the last day is for ads potasium AKA hyperemia over 5.0 now a little side note before beta blockers kind of big for pharmacology exams something called first dose phenomenon if you hear first dose or newly prescribed drug or the first time taking the drug guys don't leave the patient's bedside always assess for big side effects so in this case a big blood pressure drop all right guys that wraps it up now don't forget to see our 8 question cardiac quiz and test your knowledge in our quiz Bank thanks for watching for our full video and new quiz Bank click right up here to access your free trial and please consider subscribing to our YouTube channel last but not least a big thanks to our team of experts helping us make these great videos all right guys see you next time [Music]
