Final answer:
Among glass, plastic, metal, and wood, glass can be more reliably disinfected with a germicide due to its non-porous and durable nature.
Step-by-step explanation:
The question "Which of the following types of materials can be more reliably disinfected with a germicide?" seeks to understand which material is most susceptible to disinfection. Among the listed options, glass, plastic, metal, and wood, the material that can be more reliably disinfected with a germicide is glass. Glass surfaces are non-porous, smooth, and do not degrade when exposed to most disinfectants, making them ideal for effective and reliable disinfection.
Disinfectants are ranked by their strength and ability to kill different types of microbes. High-level germicides kill vegetative cells, fungi, viruses, and can destroy endospores leading to sterilization. Metal can also generally be disinfected well, as metal tools can be sterilized by heating. However, plastic and wood have porous surfaces that can harbor microbes, making disinfection less reliable.
Answering a related MCQ, an antiseptic (B) is suitable for use on tissues for microbial control to prevent infection. The effectiveness of chemical disinfectants has historically been compared to that of phenol (A). Items that require sterilization in a medical setting are those that will come into contact with sterile body cavities or the bloodstream. Lastly, soil (D) has yielded compounds with the most antimicrobial activity.
