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.
