Answer 1

3. After inserting the swab into the tube, the nurse surrounds the ampule at the end of the tube with gauze, crushes the ampule, and pushes the swab into the fluid.
1. The nurse cannot evaluate the results of the culture; the fluid captures the micro-organisms, and the technician mounts the fluid on slides and visualizes the specimen under the microscope.
2. The nurse avoids adding additional reagents to the tube.
4. If the nurse does not immerse the swab in the fluid, the microorganisms captured on the swab can be lost. In addition, to preserve the specimen, the nurse refrigerates the specimen after properly releasing the fluid.
