Final answer:
A. Use leather gloves as a barrier against blood and fluids.
Step-by-step explanation:
The correct answer is A. Use leather gloves as a barrier against blood and fluids. This is not part of the standard precautions recommended by the CDC. The CDC recommends wearing gloves as a barrier against blood and fluids, but they do not specify the material of the gloves. The other options - wearing a face shield if blood splatter is anticipated, placing needles directly in a puncture-proof container, and washing your hands immediately after patient contact - are all part of the standard precautions recommended by the CDC.
