These drugs dissolve clots

What are thrombolytics

100
Elevated heart rate, decrease in blood pressure, and bruising indicate this side effect.
What is Hemorrhage
100
Foods high in this, such as dark leafy greens, should be consumed in moderation when on warfarin therapy.
What is Vitamin K
100
This is monitored to evaluate heparin therapy.
What is aPTT
100
Be prepared to administer this drug when heparin overdose is suspected.
What is Protamine sulfate
200

This anticoagulant is a Vitamin K antagonist.

What is Warfarin

200
Use of anticoagulant therapy is contraindicated for patients with this hematologic abnormality.
What is Thrombocytopenia
200

Aspirin is an example of this kind of agent, which increases bleeding risk when used concurrently with anticoagulants.

What are Antiplatelets

200

While PT levels can be used to monitor warfarin therapy, this lab value is more accurate and standardized.

What is INR

200
These devices may be ordered to be used in conjunction with anticoagulants to prevent post-operative thrombi.
What are Sequential compression devices
300

If anticoagulant therapy is needed during pregnancy, I am usually what is prescribed.

What is Enoxaparin (heparin may also be used safely)

300
These fall into Pregnancy Risk Category X due to high risk of fetal hemorrhage.
What is Oral anticoagulants, such as warfarin
300
Patients on anticonvulsant therapy may require dosage adjustments due to this interaction.
What is Decrease in anticoagulant effects
300
The therapeutic range for aPTT level
What is 60 to 80 secs
300

Nurses should monitor for patients on this antiplatelet medication for tinnitus and possible GI bleeding. 

What is Aspirin

400

Warfarin is used for long-term prevention of thrombus formation associated with this cardiac dysrhythmia.

What is Atrial Fibrillation

400
These pinpoint round spots appear on the skin as a result of bleeding under the skin.
What are Petechiae
400

Women of child bearing age may need to be monitored more closely when on warfarin therapy due to an interaction with this type of medication.

What is oral contraceptives

400
An INR of 2 to 3 is the goal for most patients, but patients with these, require a higher INR (2.5 to 3.5)
What are mechanical heart valves
400

Patients must be educated about the continued need for heparin infusion after starting warfarin, due to the full therapeutic effect being achieved in this amount of time.

What is 3 to 5 days

500

I promote synthesis of coagulation factors VII, IX, X, and prothrombin.

What is Vitamin K

500

A platelet count that drops below 100,000 during heparin treatment suggests this adverse reaction.

What is Heparin-Induced Thrombocytopenia (HIT)

500

This type of drug is used to treat inflammation along with many other conditions and promotes bleeding when used with warfarin

What is Glucocorticoid

500
It is monitored every 4 to 6 hours until appropriate dosage is determined, and then daily.
What is aPTT
500

If Vitamin K cannot control bleeding in warfarin overdose, nurses should anticipate administering this.

What is Fresh frozen plasma or whole blood
