Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Failure to puncture across the fingerprint willcause:
A
blood to run down the finger
B
hemolysis
C
contamination of the sample
D
additional patient discomfort
Explanation: 

Detailed explanation-1: -If the puncture is made parallel to the fingerprints, the blood will channel down the patient’s finger instead of forming a drop at the puncture site, making the collection much more difficult.

Detailed explanation-2: -Wipe away the first drop of blood because it may be contaminated with tissue fluid or debris (sloughing skin). Avoid squeezing the finger or heel too tightly because this dilutes the specimen with tissue fluid (plasma) and increases the probability of haemolysis (60).
