Platelets (PLT)

 Platelets are produced in the bone marrow and play a role in hemostasis. Platelets function in hemostatic plug formation, clot retraction, and coagulation factor activation.

Normal values for platelet count:

• 150,000 to 400,000 cells/mm³

Nursing considerations for Platelet counts: 

• High altitudes, persistent cold temperature, and strenuous exercise increase platelet counts.
• Assess the venipuncture site for bleeding in clients with known thrombocytopenia.
• Bleeding precautions should be instituted in clients with a low platelet count.
