Final answer:
Failure to allow the alcohol to dry on the patient's arm after site cleansing can cause a stinging sensation for the patient, a possible unsterile site, and specimen hemolysis. However, it does not cause increased bacteriostatic action.
Step-by-step explanation:
Failure to allow the alcohol to dry on the patient's arm after site cleansing can cause a stinging sensation for the patient, a possible unsterile site, and specimen hemolysis. However, it does not cause increased bacteriostatic action. When alcohol is not allowed to dry, it can cause skin irritation and may affect the integrity of the specimen being collected, but it does not enhance the inhibitory action against bacteria.
