Question 1 of 5
A major complication of thyroid surgery is the accidental damaging or removal of the parathyroid glands. This damage or removal of the parathyroid glands can result in
Correct Answer: C
Rationale: Loss of PTH reduces calcium mobilization, leading to hypocalcemia.
Question 2 of 5
If the hydrogen ion concentration in the blood increases, bicarbonate ions act as buffers by
Correct Answer: A
Rationale: Bicarbonate binds excess H⁺, forming carbonic acid to stabilize pH.
Question 3 of 5
In renal compensation of acidosis,
Correct Answer: C
Rationale: Kidneys increase H⁺ excretion and HCO₃⁻ reabsorption to buffer acidosis.
Question 4 of 5
Ingesting large amounts of sodium bicarbonate can lead to
Correct Answer: B
Rationale: Excess bicarbonate raises pH, causing metabolic alkalosis.
Question 5 of 5
Azetazolamide (Diamox) is a diuretic. It functions by blocking the activity of carbonic anhydrase inside kidney tubule cells. This slows the formation of carbonic acid. By slowing the formation of hydrogen ions in the cells of the tubule, sodium reabsorption is also slowed. This results in the diuretic effect. Select from the following list the possible side-effects of Azetazolamide: 1. acidosis, 2. reduced movement of bicarbonate ion into the plasma, 3. an alkaline urine is produced, 4. respiration increases
Correct Answer: D
Rationale: Azetazolamide causes acidosis (less H⁺ formation), reduced HCO₃⁻ reabsorption, alkaline urine, and increased respiration.
