8. Cadmium is a natural element that is classified as a transition metal. Its chemical properties include which of the following?
   1. Is a lustrous blue-tinted solid.
   2. Produced in association with zinc production.
   3. Commonly occurs in a +2 oxidation state.
   4. All of the above.
9. Which of the following statements regarding the biologic fate of cadmium in the body are true
   1. Cadmium is transported in the blood bound to metallothionein.
   2. The greatest cadmium concentrations are found in the kidneys and the liver.
   3. Urinary cadmium excretion is slow; however, it constitutes the major mechanism of elimination.
   4. Due to slow excretion, cadmium accumulates in the body over a lifetime and its biologic half-life may be up to 38 years.
   5. All of the above.
10. Certain factors can increase the absorption or body burden of cadmium.
    1. Younger age.
    2. Non-smoking.
    3. Pregnancy.
    4. All of the above.
    5. None of the above.
11. During the exposure history, the key to including chronic cadmium intoxication in the differential diagnosis is
    1. A history or smoking tobacco.
    2. A history of febrile illnesses.
    3. Recent physical exercise.
    4. The use of nephrotoxic medications.
    5. Detailed questioning regarding occupations and hobbies.
12. Workers in certain industries are generally exposed to higher levels of cadmium than the general populations since
    1. Cadmium air levels can be thousands of times higher in the workplace than in the community.

    4. Pulse oximetry.
14. In order to detect renal disease from higher than average chronic exposures to cadmium, one should:
    1. Look for yellow discoloration of teeth.
    2. Order a thorough panel of renal tests including electrolytes, BUN, serum and urinary creatinine, and urinary proteins such as â₂-microglobulin and RBP.
    3. Order a set of skeletal X-rays.
    4. Order a chest X-ray.
15. Advice the physician can give the patient in order to prevent further exposures to cadmium include
    1. Avoid eating, drinking, and smoking in the workplace.
