Which lab value is a reliable indicator of bone marrow suppression in a patient receiving chemotherapy?

A.

Total protein level

B.

Serum potassium level

C.

Erythrocyte sedimentation rate (ESR)

D.

Platelet count

Answer and Explanation

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.

A. Syphilis can indeed affect many areas of the body, including the brain and heart, but this statement does not specifically address primary syphilis, which is characterized by the appearance of a painless sore (chancre) at the site of infection.
B. Syphilis does not typically resolve on its own. Without treatment, the infection can progress to more severe stages with potentially serious complications.
