Microhematocrit tubes are often referred to as "bullets" because of their size and shape. 2. Warming a capillary puncture site can increase the blood flow up to 10 times. 3. Capillary mature is sometimes recommended when available veins are fragile or must be saved for the procedures such as a glucose tolerance test. 4. Except for POCT methods, blood specimens for glucose tests cannot be collected by capillary puncture 5. Microtubes for chemistry specimens are collected first 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 palmar surface of the distal or end segment of the middle or ring finger of the dominant hand. 7. The safest area for heel puncture is the medial or lateral palmar surface of the heel 8. Neonatal bilirubin specimens must be kept cool during transportation and handling 9. Phenylketonuria is a temporarily acquired disorder. 10. 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. 11. The recommended antiseptic for capillary specimen collection is povidone-iodine. 12. "Calcaneus" is the medical term for finger bone. 13. The capillary bed in the skin of a full-term newborn is richest in capillary loops below 1 mm deep. 14. Do not squeeze the site while collecting a capillary specimen as hemoconcentration can result. 15. Underfilling a microtube can result in microclots in the specimen.

Answer 1

1) false

microcollection tubes are often referred as bullet due to shape and size

2) False

warming a capillary puncture site increases blood flow up to 7 times  

3) True

As all other veins are fragile, it is recommended to do capillary puncture

4) False

capillary blood is used for testing sugar by transferring blood to a glucose strip

5) True

the tubes with different additives are used for collecting blood specimens for a specific type of test

6) False

capillary puncher is allowed not on the dominant hand

7) true

it gets healed very fast without harming the bone the maximum incision is about 2mm

8) False

the bilirubin is sensitive to light, the effect on serum bilirubin due to delay has not been studied

9) False

it is an inherited disorder and not a temporary disorder

10) True

11)False

because it may falsely elevate the potassium phosphorus or uric acid in the blood

12) False

the calcaneus is a rectangular bone at the back of the foot

13) True

14)True

this can dilute the specimen with tissue fluids and increase the possibility of hemolysis

15) True

underfilled tube may result in micro clots, at least 89% of the tube should be filled
