Final answer:
Hand antiseptics should be used after hands are thoroughly cleaned and dried, as applying antiseptics when hands are not completely dry can reduce their effectiveness and fail to control microbial growth adequately.
Step-by-step explanation:
Antiseptics are agents that are applied to living tissue to reduce the possibility of infection, control microbial growth, and maintain hygiene. When it comes to the sequence of using hand antiseptics, it is essential that they are used after the hands are cleaned and dried properly. The recommended procedure involves first washing the hands thoroughly with soap and water, ensuring that all surfaces of the hands and the areas under the fingernails have been scrubbed evenly. After rinsing under running water, hands should be dried with a clean towel or a blower to prevent the re-contamination of the hands.
Only once the hands are completely dry should antiseptics be applied to ensure effectiveness. Applying hand antiseptic before drying can dilute the agent and diminish its antimicrobial properties. Moreover, it's essential to avoid cross-contamination after the use of an antiseptic; thus, avoiding touching potentially contaminated surfaces is advisable. This practice is particularly important in healthcare settings, where hand hygiene is critical in preventing the spread of infections.
