Clinical Medical Assistant Exam Practice Question

Correct Answer: C

Rationale: When selecting a site for venipuncture, the size and condition of the veins are crucial factors. Veins that are large and healthy are easier to puncture, reducing discomfort and increasing the likelihood of success.

While the patient's preference (A) is important for comfort, it should not override clinical considerations. The integrity of the skin (B) is relevant, but it primarily affects the puncture site rather than vein selection. The age of the patient (D) can influence vein condition, but it is not a direct factor in site selection. Thus, focusing on vein size and condition ensures a more effective and safer venipuncture procedure.
