Venipuncture disadvantages?

Venipuncture disadvantages?

• A. More invasive, requires more skill, greater risk of hematoma or nerve injury.
• B. Provides the fastest results.
• C. Requires no sterile technique.
• D. Yields smaller volumes of blood.

Answer: (A)

The main idea is that venipuncture has drawbacks because it involves puncturing a vein with a needle, making it more invasive and requiring skilled technique to do safely. This combination increases the potential for complications such as bleeding beneath the skin (hematoma) or injury to nearby structures like nerves, especially if the needle is directed or placed poorly. The procedure also demands strict sterile technique to prevent infection, and it typically takes longer to perform and to process the specimen compared with simpler collection methods or rapid point-of-care tests. In short, the invasiveness, the need for trained technique, and the higher risk of complications are the fundamental disadvantages. Statements about the fastest results, no sterile technique, or yielding smaller volumes don’t fit because venipuncture does require sterile technique and usually provides enough blood for multiple tests, with processing time not being the fastest option.
