Hey guys nurse mike here and welcome to simple nursing comm check out our brand new app get access to our new pharmacology and med search mastery courses plus the massive quiz bank loaded with detailed rationales to test your knowledge join for free click the link in our description below so first up let’s cover antiplatelet slight clopidogrel and aspirin aka

Salicylates now guys let the name help you hear anti platelets are just that they’re anti platelet they lower platelet aggregation so we have a less chance of them sticking together and clog in the arteries so just think a c4 aspirin and clopidogrel brand-name plavix like a c4 anti clogging of the arteries preventing platelets from forming clots now the indication

Is mainly for clot prophylaxis basically meaning clot prevention so guys in heart and brain clot like an mi or cva prevention narrowed arteries like a cs in the heart or a ti a in the brain or even pa d in the extremities or even prevention after a stent or bypass preventing the ria clusion of that artery there now the hesi key term we use post pci that percutaneous

Coronary intervention fancy words for cath lab to clear the clots again guys ac is aspirin and clopidogrel ac for anti clot now the mechanism action guys it’s very simple they prevent the platelets from aggregating together or clumping up sort of like spreading them out like a bunch of plates now the key points before giving we always assess so the key numbers here

Is hemoglobin levels so anything less than 7 just think you might be sending your patient to heaven huge bleed risk there and also platelets normally between 150 to 400 so just think anything less than 150 is very iffy always notify the hcp but less than 50 is very risky these meds should not be decreasing platelet levels guys this is known as thrombocytopenia

Basically meaning a huge risk for bleeding so common questions on exams they’ll give you a scenario of a platelet count about 75 thousand or less than forty guys what’s the priority nursing action always the priority is to hold the drug and question the prescription and then notify the hcp and guys don’t let the nclex trick you aspirin and kappa degrelle think

Platelets not inr not ptt that’s for anticoagulants in our next section now hesse had an exit question about aspirin they were asking about contraindication for patients with hypo prothrombin emia that’s just fancy words for low clotting factors so we just hold the aspirin now as far as aspirin toxicity this is a big focus on safety so hesse and ati exit exams had

A few questions on this so activated charcoal was the number one drug for aspirin toxicity now the key term here is initial treatment of salicylate or aspirin toxicity it binds with aspirin to block the absorption by the small intestine and the key signs of aspirin toxicity is number one tinnitus the ringing of the ears and also hyperventilation so guys we notify

The hcp immediately now caplan mentioned this as a priority finding giving us an area about a patient on aspirin who has hyperventilating indicating it could be a salicylate poisoning or aspirin poisoning an ati question about long-term aspirin administration priority assessment is assessed for tinnitus and a very last side note here tachycardia and hypotension are

Not signs of toxicity this could actually indicate a bleed so just be careful now for glycoprotein or gp receptor inhibitors we have l6m ab also an antiplatelet given for prevention of platelet aggregation but guys here’s the big difference it’s mainly used after cardiac procedures like a heart cath or coronary stent placement where we want to prevent vessel riya

Clusion now adverse effects guys just like aspirin but way more severe so we still have thrombocytopenia and bleeding now the big nursing care common exam questions ask actions the nurse should implement so key terms to write down here number one is assessment of hemoglobin and platelets again hemoglobin below 7 sends your patient to heaven and platelets below 150

Is very fe but anything less than 50 guys is very risky always question any prescription or order for an e blood thinner with platelets that low and guys we assess for bleeding here we report to the hcp these key terms red tinged urine which could be hematuria or basically blood in the urine or dark tarry stools that key term came up a lot on various quiz banks

Or it came up as black or bloody stools basically blood in the bowel we also monitor groin insertion site for signs and symptoms of bleeding after a pci and third place the client on a cardiac monitor to monitor for ecg changes and guys lastly for no needles no new ivs or ims during or after administration unless it’s absolutely necessary which on the nclex it’s

Never really absolutely necessary guys serious blood thinners are serious bleeding 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 alright guys see you next time
