What function does aldosterone serve in the body?

  • A. Aldosterone causes a release of sodium from the body, decreases fluid volume, and decreases blood pressure
  • B. Aldosterone causes a retention of sodium in the body, increases fluid volume, and increases blood pressure
  • C. Aldosterone causes a release of sodium from the body, increases fluid volume, and decreases blood pressure
  • D. Aldosterone enhances intracellular sodium production and lowers blood pressure
Correct Answer: B

Rationale: Aldosterone functions by causing the retention of sodium in the body, which results in an increase in fluid volume and blood pressure. Choice A is incorrect because aldosterone actually promotes sodium retention rather than release. Choice C is incorrect as it states that aldosterone decreases fluid volume, which is not accurate. Choice D is incorrect because aldosterone does not enhance intracellular sodium production; instead, it primarily acts on sodium reabsorption in the kidneys.
