Increased risk of bleeding into the central nervous system occurs with a platelet count of: A) 800 × 10⁹/L B) 200 × 10⁹/L C) 150 × 10⁹/L D) 30 × 10⁹/L

Question

Quizplus · Accepted Answer

A platelet count of less than 50 × 10^9/L is considered severe thrombocytopenia, which increases the risk of bleeding into the central nervous system. Therefore, the platelet count of 30 × 10^9/L (option D) is the most likely to increase the risk of bleeding into the central nervous system. Option C is borderline, as a platelet count of 100-150 × 10^9/L is considered mild to moderate thrombocytopenia, but it still carries some risk of bleeding into the central nervous system. Options A and B are not associated with an increased risk of bleeding.
