Question

which of the following scenarios represents correct capillary puncture technique? using povidone - iodine to clean the heel of an infant. scooping up blood that is running down the finger. wiping the alcohol dry so the puncture doesn’t sting. puncturing perpendicular to the fingerprint whorls.

Explanation:

Povidone - iodine can interfere with some laboratory tests, so it's not used for cleaning before capillary puncture. Scooping up blood can introduce air bubbles and contaminate the sample. Wiping the alcohol dry doesn't prevent the puncture from stinging and is not part of correct technique. Puncturing perpendicular to the fingerprint whorls minimizes damage to the skin and blood vessels and allows for better blood flow.

Answer:

Puncturing perpendicular to the fingerprint whorls.
