If a patient’s platelet count is greater than which value are most procedures considered safe?

• A. 20,000
• B. 50,000
• C. 100,000
• D. 150,000

Answer: (B)

Platelets are the key players in forming the initial hemostatic plug after a vessel is injured. For most routine procedures, having a platelet count above about 50,000 per microliter is enough to achieve reliable hemostasis, so the bleeding risk is generally low. When counts fall toward 20,000 or lower, bleeding risk rises significantly, and many procedures become unsafe or require platelet support. Counts of 100,000 or 150,000 are well above what's needed for most routine procedures; they reflect a safer margin for more invasive or high-risk interventions, but the common threshold used to say “most procedures are safe” is around 50,000.
