Short Answer

Expert verified
Answer: The primary action of clopidogrel (Plavix) is to prevent platelet aggregation.

Step by step solution

01

Read the question carefully

Read the question and options carefully to understand what is being asked. In this case, we need to identify the action of the drug clopidogrel (Plavix) prescribed to a client with a history of stroke.
02

Identify the drug class and action

Clopidogrel (Plavix) is an antiplatelet drug, which means it works by inhibiting platelets from sticking together (aggregating) and forming blood clots, thus reducing the risk of stroke or other related cardiovascular events.
03

Choose the correct option

Now let's look at the options given: A. Prevents platelet aggregation B. Dissolves clots C. Increases the coagulation of blood D. Provides diuresis Since clopidogrel is an antiplatelet drug, its primary action is to prevent platelet aggregation, therefore, the correct answer is option A.
04

Explanation of the other options

Option B: Dissolving clots is the action of another class of drugs called thrombolytics, not antiplatelet drugs. Option C: Increasing the coagulation of blood is the opposite of the desired effect. This is an action of drugs that promote blood clotting, not those that prevent it. Option D: Providing diuresis is the action of diuretic drugs, which are primarily used to promote urine production and manage fluid balance in the body. This is not related to the action of clopidogrel.
