All of the following are antiplatelet medications; EXCEPT:

Appeared in: Combined AIIMS - 2020 (Jodhpur, Bhopal, Patna, Raipur)

Explanation

The question requires identifying the drug that is NOT an antiplatelet agent.
Canglob is not a recognized or standard name for an antiplatelet medication.
Aspirin, Clopidogrel, and Cangrelor are all established antiplatelet drugs used in clinical practice.
Therefore, Canglob is the correct answer as it is the exception in the given list.

Option A: Aspirin is a classic and widely used antiplatelet medication. It works by irreversibly inhibiting the COX-1 enzyme in platelets, thus preventing clot formation.
Option B: Clopidogrel is a potent antiplatelet agent belonging to the thienopyridine class. It functions as a P2Y₁₂ receptor inhibitor, preventing ADP-induced platelet aggregation.
Option C: Cangrelor is a direct-acting, intravenous P2Y₁₂ inhibitor. It is a powerful antiplatelet drug used in acute settings, such as during coronary interventions.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Pharmacology of Antiplatelet Drugs as background academic context rather than a clinical decision trigger.
Nurses must be knowledgeable about different classes of antiplatelet agents, including their mechanisms, indications, and major side effects like bleeding.
Understanding the distinction between these drugs is vital for safe medication administration, patient monitoring for adverse effects (especially bleeding), and providing patient education on topics like medication adherence and signs of bleeding to report.
What if? - If a patient on dual antiplatelet therapy (e.g., aspirin and clopidogrel) is scheduled for elective surgery, the nurse must anticipate the need to communicate with the healthcare team about potentially holding these medications pre-operatively (typically 5-7 days) to minimize surgical bleeding risk, as per institutional protocol.

How to Approach the Question

First, identify the keyword 'EXCEPT' in the question. This means you are looking for the option that does not fit the category described.
The category is 'antiplatelet medications'.
Review each option and recall its pharmacological class.
Aspirin is a well-known antiplatelet drug (COX inhibitor).
Clopidogrel is a common antiplatelet drug (P2Y₁₂ inhibitor).
Cangrelor is also an antiplatelet drug (P2Y₁₂ inhibitor).

Concept Tested & Keywords

Concept Tested: Pharmacology of Antiplatelet Drugs
Stem keywords: antiplatelet medications, EXCEPT
Lead-in keywords: EXCEPT
Negative lead-in flag: The question uses the word 'EXCEPT', requiring identification of the option that does not belong to the specified drug class.
