Pharmacology – Nitroglycerin & Angina – by Mike
So our next d is for dilators like basil dilators like nitroglycerin commonly given for chest pain but it also works in heart failure patients to lower the blood pressure so remember the o’s here think dilators like nitro they open up the blood vessels to decrease the blood pressure by dilating the vessels and decreasing resistance in fancier terms it helps lower
Preload and afterload which lowers the blood pressure this results with more oxygen out to the body kind of like taking your thumb off a water hose you relieve the pressure and all that tension in the tube is suddenly decreased in the same way wider dilated blood vessels means less constriction and less pressure or low blood pressure now again our famous vasodilator
Is nitroglycerin so think nitro makes the blood pressure low or gives oh to to the heart muscle or just think nitro is like a pillow for the heart rested and relaxed decreased blood pressure now the top five names on the nclex are nitroglycerin nitroprusside hydralazine here’s a tricky one i so so bride which is so so tricky guys write this down it ends an ied and
Sounds so so familiar to furosemide the diuretic so very simply remember the o’s and i so so bride means it’s a vasodilator similar to nitro guys lots of o’s and the last one here is minoxidil now we only saw that one time out of 10,000 enclaves questions we took so it’s not really common on the unclutch now the killer precautions the number one thing that shows
Up on the nclex and nursing tests is no viagra drugs ending in a fill like sildenafil guys it will kill we’re talking extremely low blood pressure so a memory trick for a phil is viagra it a fills a certain male anatomy or a fill will kill and speaking of low blood pressure are two key numbers here we stop nitro if the size dalek blood pressure the number on top
Is below nine or a hundred or if we see drops by 30 points or more and nclex key words like confusion agitation even cold or pale or clammy known as diaphoretic or dizzy guys these are all early signs of low blood pressure that hypotension so we always monitor that blood pressure with nitro now normal side effects are always the three h’s usually always present
After the very first dose so headaches are hypotension also called our orthostatic hypotension and hot flushing or facial redness now this is not an allergic reaction these are common and normal so teach patients slow position changes to avoid that dizziness and falling again called that orthostatic hypotension and always check the bp before giving this drug now
For the top seven nclex tips on nitro we’re talking patch versus pill for angina patients guys we cover that in our in giant chest pain videos so if you’re watching that here on the membership site you can find it under angina in the mi section thanks to our team of experts helping us make these great videos alright guys see you next time you
