Resistive exercise may be performed if platelets exceed which threshold?

• A. 20,000
• B. 10,000
• C. 30,000
• D. 5,000

Answer: (A)

Platelet count guides how safely a patient can do resistance exercise because platelets are key to stopping bleeding from any exercise-related minor tissue trauma. When the count is low, the risk of spontaneous or easy-forcing bleeding into muscles, joints, or soft tissues increases with even light resistance.

About twenty-thousand platelets per microliter is a commonly accepted threshold to start resistive work under supervision. At this level, there’s enough clotting ability to tolerate gentle resistance and minor tissue stress, provided the activity is started slowly, progressed gradually, and performed with good technique. If the count is lower than this, resistive exercise is usually deferred to prevent bleeding risk, and the focus shifts to safe, non-resistive activities and monitoring for signs of bleeding.
