68. Two powders have been mixed together to prepare a nonsterile compound. To ensure the mixture is evenly distributed, it must be:
Answer: A
The mixture must be homogeneous.
To ensure that the two powders are evenly distributed in the nonsterile compound, the mixture must be homogeneous, meaning that its composition is uniform throughout.
A) homogeneous.
This option is correct because a homogeneous mixture ensures that the components are evenly distributed, which is essential for the effectiveness and consistency of the compound being prepared.
B) liquid.
This option is incorrect. While some mixtures can be liquid, the state of the mixture (liquid or solid) does not guarantee even distribution. A homogeneous mixture can exist in various states, including solid and liquid.
C) stable.
This option is incorrect. Stability refers to the ability of a compound to maintain its composition and properties over time, but it does not address the need for uniform distribution of components within the mixture.
D) non-hazardous.
This option is incorrect. Non-hazardous indicates that the mixture does not pose a risk to health or safety, but this does not pertain to the even distribution of the powders within the compound.
Conclusion
The requirement for the mixture to be homogeneous is crucial for ensuring that both powders are evenly distributed, which directly impacts the quality and effectiveness of the nonsterile compound. All other options fail to address the necessity of uniformity in the mixture, focusing instead on unrelated aspects such as state, stability, or safety.
