For the most effective microbial killing,all iodophors must be properly diluted because:
A) They stain the skin if too concentrated.
B) This decreases contact time for adequate killing.
C) There must be enough free iodine to kill the microorganisms.
D) This increases contact time for adequate killing.

Question

Quizplus · Accepted Answer

When iodophors are used as skin preparations,contact time is essential for killing microorganisms.Contact time does not depend on dilution.Iodophors are considered nonstaining.The reason for diluting iodophors properly is that the dilution ratio is important to ensure there is enough free iodine to kill microorganisms.
