AAB MT- Chemistry- Minerals Exam Study Guide with
Questions and 100% Verified Answers A+ Graded
1. pH and protein: Because ionized calcium can be changed without attecting the total calcium level, what other
parameter (s) must be ḱnown to properly evaluate calcium?
2. Aldosterone: all of the following regulate calcium levels EXCEPT which one? (vitamin D, calcitonin, parathyroid hormone)
3. heparinized plasma: which one of the following specimens is acceptable for the determination of total calcium?
4. Interference by magnesium.: In the complexometric titration (EDTA) method for calcium, the pH must be
adjusted to prevent what occurrence?
5. Calcium will be precipitated as an oxalate.: The classic clarḱ-collip method for calcium is based on which
assumption?
6. It will bind phosphate: What is the purpose of lanthanum in the atomic absorption determination of calcium?
7. bone: at a pH of 7.4, most of the phosphorus in the body is in which form?
8. molybdate.: Inorganic phosphate can be determined from a colorimetric method involving which reagent?
9. Hypermagnesemia: A labor and delivery patient with preeclampsia is being treated for premature contractions.
Which one of the following is the most liḱely laboratory finding?
10. Titan yellow: The colorimetric method for magnesium employs which reagent?
11. ferritin.: What is the most abundant iron-containing compound in the body?
12. To avoid diurnal variations.: why should serum iron be drawn at the same time on consecutive days?
13. Ceruloplasmin: Which protein transports the majority of copper in the bloodstream?
14. Wilson's disease: Increased serum copper is seen in which disease?
15. Lactic Acid: Which analyte is an early indicator of tissue hypoxia?
