Venipuncture advantages?

Venipuncture advantages?

• A. Larger blood volume, more accurate, multiple tubes can be collected.
• B. Less invasive and easier for patients.
• C. Requires no skill to perform.
• D. Never causes hematoma or nerve injury.

Answer: (D)

Accessing a larger volume of blood and the ability to collect multiple tubes in a single draw are the main advantages of venipuncture. When you need several tests or a panel of tests, having more blood available reduces the need for repeat procedures and allows simultaneous processing, which can improve efficiency and consistency. A bigger, well-mixed sample also supports more reliable analyses and quality control, especially for tests that require separate tubes for different processing (e.g., serum vs. plasma, or additive-specific assays). It’s important to recognize that venipuncture is invasive and does require proper technique to minimize risks, such as hematoma or nerve injury; those are potential complications, not advantages. Options that are less invasive or claim no skill are not accurate descriptions of venipuncture, and they don’t capture the practical benefit of obtaining sufficient blood volume and multiple tube collections.
