: The first statement assumes that microhematocrit tubes are often referred to as "bullets" due to their size and shape. : The second statement says that warming a capillary puncture site can increase the blood flow up to 10 times. : The third statement mentions that capillary puncture is sometimes recommended when available veins are fragile or must be saved for other procedures such as a glucose tolerance test. : The fourth statement says that except for POCT methods, blood specimens for glucose tests cannot be collected by capillary puncture. : The fifth statement mentions that microtubes for chemistry specimens are collected first in the order of draw for capillary puncture. : The sixth statement mentions that the CLSI recommended site for capillary puncture on adults and children older than 1 year is the palmar surface of the distal or end segment of the middle or ring finger of the dominant hand. : The seventh statement mentions that the safest area for heel puncture is the medial or lateral palmar surface of the heel. : The eighth statement mentions that neonatal bilirubin specimens must be kept cool during transportation and handling. : The ninth statement mentions that phenylketonuria is a temporarily acquired disorder. : The tenth statement mentions that blood spot circles for newborn screening tests are filled by applying a large drop of free-flowing blood to each side of the filter paper. : The eleventh statement mentions that the recommended antiseptic for capillary specimen collection is povidone-iodine. : The twelfth statement mentions that "calcaneus" is the medical term for finger bone. : The thirteenth statement mentions that the capillary bed in the skin of a full-term newborn is richest in capillary loops below 1-mm deep. : The fourteenth statement mentions that one should not squeeze the site while collecting a capillary specimen as hemoconcentration can result. : The fifteenth statement mentions that underfilling a microtube can result in microclots in the specimen. : The sixteenth statement mentions that adhesive bandages can roll up and cause a tourniquet effect that cuts off blood flow. The corrected statements are: 1. Microhematocrit tubes are sometimes referred to as "bullets" because of their size and shape. 2. Warming a capillary puncture site can increase the blood flow up to 5 times. 3. Capillary puncture is sometimes recommended when available veins are fragile, hard to find, or must be saved for other procedures such as a glucose tolerance test. 4. Except for POCT methods, blood specimens for glucose tests should be collected by venipuncture, not capillary puncture. 5. Microtubes for chemistry specimens are collected last in the order of draw for capillary puncture. 6. The CLSI recommended site for capillary puncture on adults and children older than 1 year is the volar surface of the distal or end segment of the middle or ring finger of the non-dominant hand. 7. The safest area for heel puncture is the lateral or medial plantar surface of the heel. 8. Neonatal bilirubin specimens must be kept warm during transportation and handling. 9. Phenylketonuria is a congenital and inherited disorder. 10. Blood spot circles for newborn screening tests are filled by applying a small drop of free-flowing blood to the center of the filter paper. 11. The recommended antiseptic for capillary specimen collection is 70% isopropyl alcohol. 12. "Calcaneus" is the medical term for heel bone. 13. The capillary bed in the skin of a full-term newborn is richest in capillary loops below 0.5-mm deep. 14. One should not squeeze or milk the site while collecting a capillary specimen as hemoconcentration or hemodilution can result. 15. Underfilling a microtube can result in microclots or prevent adequate mixing of the specimen. 16. Adhesive bandages or tape can roll up and cause a tourniquet effect that can cause hemoconcentration or hemodilution.
