Question 1 of 5
Sensible perspiration
Correct Answer: C
Rationale: Sensible perspiration is sweat gland secretion, visible on the skin.
Question 2 of 5
In renal compensation of acidosis,
Correct Answer: C
Rationale: Kidneys increase H⁺ excretion and HCO₃⁻ reabsorption to buffer acidosis.
Question 3 of 5
Ingesting large amounts of sodium bicarbonate can lead to
Correct Answer: B
Rationale: Excess bicarbonate raises pH, causing metabolic alkalosis.
Question 4 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.
Question 5 of 5
The largest compartment of body fluids is the compartment.
Correct Answer: A
Rationale: The intracellular compartment is the largest, holding about 60% of body water.
