What is the general procedure for plasma donation after the initial screening?

The correct answer highlights the critical step that follows the initial screening process for plasma donation. After ensuring that the donor meets all health and eligibility criteria during the screening, the next step is to insert a needle to initiate the plasmapheresis process. This procedure is designed to draw blood from the donor, separate plasma from other blood components, and return the remaining components back into the donor’s bloodstream.

This direct transition from screening to plasmapheresis is essential to facilitate efficient plasma collection, ensuring a smooth experience for both the donor and the facility. The other options do not reflect the immediate subsequent action following the screening, as they either suggest inactivity or separate scheduling, which would not align with the established protocol for plasma donation.
