A platelet count below which value suggests avoiding intramuscular injections or venipuncture?

• A. 20,000
• B. 100,000
• C. 50,000
• D. 250,000

Answer: (C)

Low platelets impair the body's ability to form a stable clot after tissue injury. When a needle punctures muscle or a vein, some bleeding is expected, but with fewer platelets there isn’t enough to seal the small vessels quickly, increasing the risk of a hematoma or excessive bleeding. That risk becomes clinically significant around fifty thousand platelets per microliter, so intramuscular injections or venipuncture are generally avoided when the count falls to or below that level. A normal platelet count is much higher, typically around 150,000 to 450,000, which supports safe needle procedures with standard precautions. Counts around twenty thousand or lower are associated with a higher likelihood of spontaneous bleeding, but the specific practice guideline for avoiding these procedures is the fifty-thousand threshold.
