N126-U3-1. MI/CHF #8

Dobrisky-Cardiac Module: Meds #2

QuestionAnswer
An example of an antiplatelet agent is an aspirin
Aspirin inhibits thromboxane-induced platelet aggregation
Thromboxane-induced platelet aggregation is inhibited by aspirin
Clopidogrel prevents platelet activation
platelet activation is prevented by what medicine? clopidogrel
What is the #1 nursing priority for a patient taking antiplatelet agents? monitor for bleeding
Aspirin and Clopidogrel are examples of antiplatelet agents
Which antiplatelet agent prevents platelet activation? Clopidogrel
Which antiplatelet agent inhibits thromboxane-induced platelet aggregation? Aspirin
Fibrinolytics are used in the treatment of a MI
Fibrinolytics work by lysing the clots associated with plaque rupture and vessel occlusion of MI
Common Fibrinolytics end in what? -ase
Alteplase, Reteplase, Tenecteplase and treptokinase are all common fibrinolytics
What common reaction to fibrinolytics should a nurse warn a patient about? bruising
While receiving these medications patients should be monitored for bleeding, hypersensitivity, heart & lung sounds fibrinolytics
fibrinolytic use requires monitoring of which labs? Hct, Hgb, platelet count, fibrin, PTT, PT
Glycoprotein IIb/IIIa receptor inhibitors affect the final pathway in platelet thrombus formation by binding to GP IIb/IIIa receptor sites
"fib" & "cix" meds are glycoprotein IIb/IIIa receptor inhibitors
Tirofiban, Epitifibatide and Abciximab are all examples of glycoprotein IIb/IIIa receptor inhibitors
What is the #1 nursing priority for patients taking GP IIb/IIIa receptor inhibitors? bleeding
to prevent propagation of an established thrombus a patient is given anticoagulants
unfractionated heparin and low-molecular heparin are both common anticoagulants
what is the #1 nursing diagnosis for anticoagulant usage? monitor for bleeding
what labs when decreased are of concern when a patient is taking anticoagulants? Hct and Hgb
When giving unfractionated heparin what must be done before administering? check PTT
one advantage of a low molecular weight is that it does not require heparin PTT
When should PTT levels be drawn 30 minutes before administration and 6 hours after administration
how often should PTT levels be drawn after administration of heparin? every 6 hours
how soon before heparin administration should PTT levels be drawn? 30 minutes before
When injecting heparin do you aspirate? NO
Dose of heparin is determined by the patient's weight
After injecting heparin pressure should be applied to the wound or IV site for 1-2 minutes at least
the therapeutic level for PTT is 1.5 to 2.5 times the normal value
the normal value for aPTT is 24-36 seconds
the normal value for PT is 10-14 sec
