Explanation:

1. Prolonged bleeding after needle withdrawal is not a reason for specimen re - collection among the options. Incomplete drying of antiseptic, wrong antiseptic, and glove powder contamination can affect specimen quality.
2. Keeping the patient's arm elevated above the heart is not a measure to avoid anticoagulant reflux. Allowing tube to fill from bottom - up, removing last tube before tourniquet and before needle are valid measures.
3. Edematous tissue, mastectomies, and hematomas can all affect specimen quality or patient safety during blood draw.
4. Povidone - iodine is not recommended for blood alcohol draws as it can interfere with results.
5. Hemolysis is the destruction of blood cells.
6. Blood alcohol level is not affected by patient position. Albumin, cholesterol, and enzymes can be affected.
7. Lymphostasis is lack of lymph fluid movement.
8. Applying a moist warm cloth to the area can enhance vein prominence.
9. Hemoconcentration is alteration in the ratio of elements in the blood.
