Final answer:
Alcohol may affect the results of tests for bilirubin, uric acid, potassium, and phosphorus from a dermal puncture and should not be used. It denatures proteins and disrupts membranes, which can interfere with accurate measurements.
Step-by-step explanation:
Of the given options, the antiseptic that may affect the results of tests for bilirubin, uric acid, potassium, and phosphorus from a dermal puncture and therefore should not be used on a dermal puncture is Alcohol. Alcohol, including ethyl alcohol and isopropyl alcohol, is a commonly used antiseptic that acts by denaturing proteins and disrupting membranes. However, it can interfere with the accurate measurement of certain substances in blood, such as bilirubin, uric acid, potassium, and phosphorus. Therefore, it should be avoided when performing tests involving dermal puncture.
