When monitoring platelet count post bone marrow transplant, what threshold indicates exercise should be contraindicated?

• A. Less than 10,000
• B. Less than 20,000
• C. Less than 30,000
• D. Less than 40,000

Answer: (B)

Monitoring platelet counts is critical in patients who have undergone a bone marrow transplant, as low platelet levels can significantly increase the risk of bleeding. In this context, a threshold of less than 20,000 platelets/mm³ is recognized as a level where exercise should be contraindicated. This is primarily because at this count, the risk of spontaneous bleeding becomes markedly higher, potentially leading to serious complications. Patients with platelet counts below this threshold may not be able to manage activities that could lead to injury, even from minor trauma. Therefore, exercise should be avoided to ensure patient safety and to prevent any unnecessary health risks. With platelets dropping below 20,000, even activities of daily living could pose a danger, emphasizing the importance of careful monitoring and adherence to guidelines regarding activity restrictions in these vulnerable patients.
