NCLEX questions
and answers
The nurse is preparing a patient with acute
chest pain for an emergency angioplasty. The
nurse would anticipate administering which
medication to prevent platelet aggregation?
Tirofiban (Aggrastat)
Tirofiban is a glycoprotein IIb/IIIa inhibitor
that blocks the enzyme essential for platelet
aggregation. This is given to prevent the
formation of further clots and is faster acting
than warfarin. Protamine sulfate is the
antagonist for heparin, not an anticoagulant.
, Aminocaproic acid is an antifibrinolytic, the
opposite of what is needed in this situation.
Enoxaparin sodium (Lovenox) is an
anticoagulant used to prevent and treat deep
vein thrombosis and pulmonary embolism.
This medication is in which drug class?
Low-molecular-weight heparin
The patient asks the nurse, "What is the
difference between dalteparin (Fragmin) and
heparin?" What is the nurse's best response?
"Dalteparin is a low-molecular-weight heparin
that has a more predictable anticoagulant
effect."
A low-molecular-weight heparin is more
predictable in its effect than regular heparin.
Dalteparin is more expensive than heparin
and is dosed based on the patient's weight.
The nurse recognizes that the patient
understands the teaching about warfarin
(Coumadin) when the patient verbalizes an
increased risk of bleeding with concurrent
use of which herbal product?
-Garlic
-St. John's wort
