Dobrisky-Cardiac Module: Meds #2
Question | Answer |
---|---|
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 |
