In this video, Cathy covers the following medications: Vasodilators (nitroprusside) and Antianginal medications (nitroglycerin, isosorbide mononitrate, isosorbide dinitrate).
Alright. in this video, we are going to talk about some important vasodilators. if you are following along with cards, i am on card number 19, which talks about nitroprusside, which is a vasodilator is that it causes direct vasodilation of arteries and veins, so it brings that blood preload and after load. so this
Medication, like i said, it brings the blood pressure down very rapidly, so hypotension is going to be a in fact, this particular medication does pressure. so that’s definitely a key side effect. a couple of other key side effects to keep in mind are cyanide toxicity as well thiocyanate toxicity. so those aren’t
Side effects that you see every day. and in fact, i don’t know another medication that has those. so those are unique side effects dizziness as well as gi upset. so we have one of our level of crew members who provided a great tip for remembering this drug. so nitroprusside may “pruss” you into so if your patient is
Getting nitroprusside then has severe hypotension, then you’ll want to take some interventions based on your facility policy. this can include raising the patient’s legs, decreasing the dose of nitroprusside, and increasing fluids. but again, you’ll need to refer to your facility policy for those interventions. that are
Used to treat angina. the important isosorbide mononitrate and isosorbide dinitrate. so these medications work to treat angina through vasodilation. so they decrease the preload, and the side effects of these antianginal medications are very important to know. as a headache and possible reflex tachycardia. medications
Cause a headache, is i think about eating some icy sorbet, which kind of looks like isosorbide. and when you eat an icy sorbet, remember that isosorbide medications also so, if your patient has sublingual nitroglycerin, then they need to keep this stored in a cool dark place. if they have chest pain, they can take up
To three tablets, right? so they would place one under the tongue, wait five minutes. if they are still having chest pain, they need to call 911, and then put a second one under the tongue, wait five minutes, and then if there’s still no relief, and then, if you are giving nitroglycerin not absorbing the medication
In your hands. and just in general, wear your gloves as and then, you want to remove the prior dose. so often, we apply this nitroglycerin on the you remove the prior dose. you want to make choose a clean, hairless area to place the new dose. right? so if the patient has a bunch of hair and you stick it on top of
The hair, alright. in my next video, we will get into antidysrhythmic medications. if our free video and subscribe to us here at level up rn!
