Question 1 of 5
As a result of hyperventilation,
Correct Answer: B
Rationale: Hyperventilation reduces CO₂ lowering carbonic acid and raising pH.
Question 2 of 5
Which of the following regulatory mechanisms would be stimulated as a result of the increased osmolality that results from a Na⁺ level of 152 mEq/L?
Correct Answer: B
Rationale: High osmolality (from Na⁺ 152 mEq/L) triggers ADH to retain water.
Question 3 of 5
excessive intake of antacids
Correct Answer: D
Rationale: Antacids (bases) raise pH, leading to metabolic alkalosis.
Question 4 of 5
The main intracellular cation is
Correct Answer: A
Rationale: Potassium dominates inside cells, critical for membrane potential.
