1

Which antiseptic agent provides the most rapid and sustained bacterial reduction for intact skin at most surgical sites?

Aqueous chlorhexidine alone
Sterile saline
Chlorhexidine in alcohol solution
Povidone-iodine applied briefly without drying

2

A patient is scheduled for excision of a lesion on the inside of the cheek. Which antiseptic approach is most appropriate?

Apply povidone-iodine or aqueous chlorhexidine to the oral mucosa
Use alcohol-based chlorhexidine liberally to maximize microbial kill
Skip antiseptic application to avoid irritating the mucosa
Apply povidone-iodine and rinse immediately with sterile saline

3

Which of the following best describes a limitation of povidone-iodine compared to chlorhexidine-alcohol?

It is unsafe for use in low-resource settings where solutions may be reused
It is more easily inactivated by blood or pus and requires longer contact and drying time
It cannot be used on mucous membranes under any circumstances
It provides longer residual activity than chlorhexidine

4

In a rural facility, the only antiseptic available is a large bottle of povidone-iodine that staff commonly dip gauze into for multiple patients. What is the safest adaptation a nurse can implement?

Continue dipping gauze into the same bottle but use fresh gauze for each patient
Use the iodine directly from the main container but increase drying time
Dispense small amounts into sterile containers for each patient and discard unused portions after the case (replace current bottle of povidone-iodine, if possible)
Dilute the iodine with sterile saline to extend its use across more patients
