Batch 2011 Pretest[edit]

  1. What is the principle? Calcium is precipitated from serum as oxalate, which is titrated with potassium permanganate.
  2. Calcium exists in the blood in three fractions: ionized, protein-bound, and citrate.
  3. Normal concentration of calcium in serum is: 9-11.5 mg/100ml.
  4. Metabolism of calcium is largely related to: phosphorus.
  5. A decrease in the ionized fraction of serum calcium causes: tetany.
  6. What is the function of ammonium? Bind with oxalate.
  7. What is the function of potassium permanganate? Oxidizer.
  8. Inonized calcium in the body fluids is important in: Blood coagulation, maintaining normal excitability of the heart, and differential aspects of the membrane permeability.
