Drawing more than the recommended amount of an infant's blood volume may result in which of the following conditions?

Choice A Reason:
Inverting the tube 5 to 7 times may not be sufficient to mix the blood thoroughly with the EDTA. This could lead to partial clotting and potentially inaccurate test results. The EDTA anticoagulant works by binding calcium ions, which are necessary for blood clotting. Without adequate mixing, the EDTA may not be evenly distributed, leaving some areas of the blood sample able to clot.

Choice B Reason:
Inverting the tube only 2 to 4 times is inadequate for proper mixing. This minimal agitation would likely result in clot formation because the anticoagulant would not be sufficiently mixed with the blood. Clots can interfere with the accuracy of hematological tests by trapping cells and altering the specimen's composition.

Choice C Reason:
Inverting the tube 1 to 3 times is clearly insufficient and would almost certainly lead to clotting. The purpose of inverting the tube is to ensure that the EDTA coats all the blood cells, preventing coagulation. Such a low number of inversions would not allow for the anticoagulant to perform its function effectively.

Choice D Reason:
Inverting the tube 8 to 10 times is the recommended practice. This number of inversions ensures that the blood is fully mixed with the EDTA, preventing clot formation and preserving the integrity of the sample for accurate laboratory analysis. It is important to perform these inversions gently to avoid hemolysis, which can also affect test results. Hemolysis occurs when red blood cells are damaged and their contents leak out, which can happen if the blood is shaken too vigorously.

Choice A reason:
A specimen bag is typically used for transporting specimens from the collection site to the laboratory. It is not designed for the disposal of contaminated items such as microscope slides. These bags are not puncture-resistant and do not provide the necessary protection against sharps injuries or contamination.

Choice B reason:
A biohazard bag is used for disposing of items that have been contaminated with potentially infectious materials. While it is suitable for materials like gloves, tissues, or any other items that do not have sharp edges, it is not the appropriate choice for glass slides, which can puncture the bag and pose a risk to handlers.

Choice C reason:
A red sharps container is specifically designed for the disposal of sharps waste, which includes any device that can puncture or cut skin, such as needles, syringes, lancets, and contaminated glass such as microscope slides. These containers are rigid, puncture-resistant, leak-proof, and usually marked with a biohazard symbol, making them the correct choice for disposing of contaminated microscope slides.

Choice D reason:
A medical waste container is a broad term that can refer to various types of containers used for medical waste. However, not all medical waste containers are suitable for sharps disposal. Unless the medical waste container is designed like a red sharps container, it may not be safe for disposing of glass slides.
