Answer to Question 1

Ans:
B

Feedback:

Anemia is the cardinal sign of lead toxicity. Muscle pain, decreased deep tendon reflexes, nor changes in WBC levels are associated with lead toxicity.

Answer to Question 2

Ans:
A

Feedback:

Immunohistochemistr y can be used to determine the site of origin of metastatic tumors. In cases in which the origin of the metastasis is obscure, immunochemical detection of tissue-specific or organ-specific antigens can often help to identify the tumor source. Tumor markers, microarray technology, and biopsy are less likely to aid in identifying the primary source.
