A nurse is disinfecting the room of a client who has a Clostridium difficultiesinfection. Which of the following solutions should the nurse use?
Chlorhexidine.
Isopropyl alcohol.
Chlorine bleach.
Triclosan.
The Correct Answer is C
According to the CDC1, chlorine bleach is an effective disinfectant for killing C. difficile spores on environmental surfaces.
It should be used in a 1:10 dilution of household bleach and water, freshly mixed daily.
Chlorine bleach can also kill other pathogens that may be present in the room of a client with C. difficile infection.
Choice A is wrong because chlorhexidine is not effective against C. difficile spores.
Chlorhexidine is an antiseptic that can be used for hand hygiene and surgical asepsis, but it does not kill spores.
Choice B is wrong because isopropyl alcohol is also not effective against C. difficile spores.
Alcohol-based hand sanitizers are not sufficient for preventing the spread of C. difficile, and soap and water should be used instead.
Choice D is wrong because triclosan is a type of antibacterial agent that is commonly found in some consumer products, such as soap and toothpaste. However, triclosan has no activity against C. difficile spores.
Triclosan may also contribute to antibiotic resistance and has potential adverse effects on human health and the environment.

Correct Answer is B
Explanation
This type of aphasia is caused by damage to the frontal lobe of the brain, which affects the ability to produce language.
People with expressive aphasia can understand speech and know what they want to say, but they have difficulty saying words or forming sentences.
They may speak in short phrases that require a lot of effort.
Choice A is wrong because receptive aphasia is a type of fluent aphasia that affects the ability to comprehend language.
People with receptive aphasia have difficulty understanding speech and may produce meaningless words or sentences.
Choice C is wrong because global aphasia is the most severe type of aphasia that affects both the production and comprehension of language.
People with global aphasia cannot speak many words and do not understand speech.
They also cannot read or write.
Choice D is wrong because sensory aphasia is not a common term for a type of aphasia.
It may refer to Wernicke’s aphasia, which is another type of fluent aphasia that affects the ability to produce meaningful language.
People with Wernicke’s aphasia can speak fluently but often use incorrect or invented words or phrases.
Correct Answer is B
Explanation
This action will help the client hear the nurse better by reducing competing sounds.
The nurse should also face the client when speaking, use short phrases, and communicate using paper and pen if needed.
Choice A is wrong because using short phrases alone is not enough to promote communication with a client who has hearing loss.
The nurse should also use other strategies such as decreasing background noise and facing the client when speaking.
Choice C is wrong because speaking in a loud voice can distort the sound and make it harder for the client to understand.
The nurse should speak clearly, slowly, and distinctly, but not shout.
Choice D is wrong because talking at a rapid rate can make it difficult for the client to follow the conversation.
The nurse should speak at a normal pace and pause between sentences.
