Which hemostatic disorder usually is represented by a decreased platelet count, normal PT, normal APTT, and abnormal closure time?
A) Thrombocytosis
B) Thrombocytopenia
C) Vascular disorder
D) Platelet dysfunction

Question

Quizplus · Accepted Answer

Thrombocytopenia is a disorder characterized by a decreased platelet count, which can lead to impairments in hemostasis. The normal PT and APTT indicate that there is no significant deficiency in clotting factors or inhibitors, respectively. However, the abnormal closure time suggests that platelet function may be impaired. Thrombocytosis, on the other hand, is a disorder characterized by an increase in platelet count and would not result in a decreased count. Vascular disorders and platelet dysfunction may also contribute to impaired hemostasis, but these are not consistent with the specific laboratory findings presented in this question.
