A nurse is caring for a patient who reports an increase in bruising. The nurse should expect which of the following laboratory values?
Platelets 110,000 mm3
WBC 8,000 mm3
Hemoglobin 13.0 g/dL
RBC 4.6 million/mm3
The Correct Answer is A
A. Platelets 110,000 mm³ – Correct Answer. A low platelet count (thrombocytopenia) increases the risk of bruising and bleeding. Normal platelet range is 150,000–400,000 mm³.
B. WBC 8,000 mm³ – Normal white blood cell count; does not explain increased bruising.
C. Hemoglobin 13.0 g/dL – Normal hemoglobin level; not related to bruising.
D. RBC 4.6 million/mm³ – Normal RBC count; does not indicate a bleeding risk.
