Final answer:
For patients sensitive to alcohol, alcohol-free antiseptic wipes can be used to sanitize the blood collection site. Povidone-iodine may be used as well if there is no sensitivity to iodine.
Step-by-step explanation:
When a patient is sensitive to alcohol, it is advisable to use an alternative antiseptic for sanitizing the blood collection site. Choice 4, alcohol-free antiseptic wipes, are appropriate for patients with alcohol sensitivity. These wipes usually contain antiseptics that are less irritating to the skin and are effective in reducing microbial flora without the use of alcohol.
Povidone-iodine (choice 2) may also be used if there are no contraindications or sensitivities to iodine, as it is a common and effective antiseptic for skin disinfection as mentioned with the use of Betadine. However, chlorhexidine and hydrogen peroxide are not typically used for skin disinfection prior to blood withdrawal due to potential tissue toxicity and less efficacy as skin antiseptics.
