Sample item

Which skin antiseptic is preferred for preparing the site before inserting a central venous catheter, to lower the risk of bloodstream infection?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Chlorhexidine in alcohol

Chlorhexidine in alcohol is preferred and is part of the insertion bundle with maximal barrier precautions. It has a rapid and persistent antimicrobial effect and reduces catheter-related infection more than aqueous povidone-iodine.

Option by option

  • A. Chlorhexidine in alcohol (correct)

    Correct. It acts rapidly and persistently and is the preferred skin preparation.

  • B. Normal saline

    Saline has no antimicrobial action.

  • C. Hydrogen peroxide

    Hydrogen peroxide is not a skin antiseptic for line insertion.

  • D. Aqueous povidone-iodine

    Aqueous povidone-iodine is less effective and acts more slowly.
