Certified Clinical Medical Assistant Exam Practice Question

Correct Answer: C

Rationale: The average adult has approximately 5 liters of blood, which is essential for transporting oxygen, nutrients, and waste products throughout the body.

Option A (12 L) exceeds the normal blood volume for adults, which could lead to serious health issues. Option B (10 L) is also too high, as it is closer to the blood volume seen in larger animals. Option D (2 L) is significantly below the average, indicating a severe deficiency that would be life-threatening. Understanding these volumes is crucial for recognizing normal physiological function and potential medical conditions.
