Clinical Medical Assistant Exam Practice Question

Correct Answer: C

Rationale: Point of care capillary testing generally requires a minimal blood volume, typically around 0.1 ml, making option C the most accurate.

Option A (2 ml) is excessive for capillary tests, which are designed for quick, small samples. Option B (0.5 ml) is also too high, as it exceeds the typical volume needed for most capillary assays. Option D (1 ml) is still more than what is generally required, as capillary tests aim to minimize discomfort and sample size. Thus, 0.1 ml is optimal for effective and efficient testing.
