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.

Correct Answer is C
Explanation
A. Presence of Bence-Jones protein in the urine is indicative of multiple myeloma, but hypercalcemia is a more urgent issue to address.
B. Severe back pain is common in multiple myeloma due to bone involvement, but it is not as immediately life-threatening as hypercalcemia.
C. Elevated serum calcium levels (hypercalcemia) are a common complication of multiple myeloma and can lead to various complications, including kidney damage, altered mental status, and cardiac arrhythmias. Therefore, it is crucial to report significantly elevated serum calcium levels promptly to the health care provider for appropriate management.
