Which lab value is a reliable indicator of bone marrow suppression in a patient receiving chemotherapy?
Total protein level
Serum potassium level
Erythrocyte sedimentation rate (ESR)
Platelet count
The Correct Answer is D
A. Total protein level. Total protein level does not directly indicate bone marrow suppression.
B. Serum potassium level. Serum potassium level reflects electrolyte balance but is not specific for bone marrow suppression.
C. Erythrocyte sedimentation rate (ESR). ESR can indicate inflammation but is not a reliable indicator of bone marrow suppression.
D. Platelet count. Platelet count is a reliable indicator of bone marrow suppression because chemotherapy can significantly reduce platelet production, leading to thrombocytopenia.
