Question 66

Alcohol-based surgical hand scrub may be used to inhibit microbial growth.

Alcohol-based surgical hand scrubs are effective in reducing and inhibiting microbial growth on the skin, thereby helping to prevent infections during surgical procedures.

A) sorption and leaching.

Sorption and leaching refer to the processes by which substances are absorbed or released in materials, which is not the primary function of alcohol-based surgical hand scrubs. These scrubs are specifically designed to target microbial organisms rather than address issues related to the physical properties of materials.

B) stability and compatibility.

Stability and compatibility pertain to the ability of substances to remain unchanged and to interact safely with other substances, respectively. While alcohol-based surgical hand scrubs may have stable formulations, their primary purpose is not related to these chemical properties but rather to the reduction of microbes.

C) microbial growth.

Alcohol-based surgical hand scrubs are formulated to significantly reduce microbial growth on the skin. They contain alcohol, which acts as an antiseptic agent, effectively killing bacteria and viruses, thus ensuring a sterile environment before surgical procedures.

D) synergistic reactions.

Synergistic reactions involve the interaction of two or more substances to produce a combined effect greater than the sum of their individual effects. This concept is not applicable to the function of alcohol-based surgical hand scrubs, which focus on microbial inhibition rather than chemical interactions.

Conclusion

Alcohol-based surgical hand scrubs are specifically designed to inhibit microbial growth, making option C the clear and correct choice. The other options do not accurately reflect the primary purpose of these scrubs, which is to ensure hygiene and reduce the risk of infection during surgical procedures.
