The nurse notes that a child's gums bleed easily and bruising and petechiae are evident on the extremities. Which laboratory value would be consistent with these symptoms?
a. Platelet count of 19,000/mm3
b. Prothrombin time of 11 to 15 seconds
c. Hematocrit of 34
d. Leukocyte count of 14,000/mm3
A
The normal platelet count is 150,000 to 400,000/mm3 . This finding is very low, indicating an increased bleeding potential. The prothrombin time of 11 to 15 seconds is within normal limits. The normal hematocrit is 35 to 45 and, although this finding is low, it would not create the symptoms presented. A leukocyte count of 14,000/mm3 indicates the probable presence of infection but is not a reflection of bleeding tendency.
