If a patient's medication inhibits glycoprotein IIb/IIIa receptors on platelets, which consequence follows during an injury that causes bleeding?

A)Increased thromboxane A2 production results
B)Enhanced fibrinogen binding takes place
C)Accelerated activation of factor XIII occurs
D)Reduced platelet aggregation is observed

💡 Explanation

Inhibition of glycoprotein IIb/IIIa receptors reduces platelet aggregation, because these receptors mediate platelet cross-linking via fibrinogen binding. Therefore, reduced platelet aggregation occurs, rather than increased thromboxane production or enhanced fibrinogen binding, which would promote clotting.
