Please read the clinical scenario, and then answer the question that follow to become familiar with the traditional NCLEX question format. Wanda is a medical assistant and the newest employee of your healthcare team. You notice that she does not wash her hands in between patients. From your microbiology background, you understand that microbes are not visible with the naked eye. As the only nurse in your small medical office, you take it upon yourself to educate Wanda on the importance of aseptic techniques. -Louis Pasteur hypothesized that microbes were in the air and dust.Through experiments using swan-necked flasks,he disproved the concept of 2-12-13

Please read the clinical scenario, and then answer the questions that follow to become familiar with the traditional NCLEX question format. Breonna Jones is 16 years old, 5’4”, and weighs 93 lb. She was admitted 2 days ago after collapsing at the local high school. Her parents knew she was skinny but had no idea how emaciated she was, or that her life was in danger. As you develop Breonna’s plan of care, you take into consideration the four major biological molecules that are building blocks of all cells. -Carbohydrates,lipids,proteins,and nucleic acids are the four main families of biological molecules referred to as

The first cells appeared about ___ billion years ago.

Koch's postulates are criteria used to establish that

If you were a microbiologist in 1950,which of the following scientific principles would you already know?

Ms. Smith is a 29-year-old patient at the outpatient psychiatric clinic. While completing her assessment you notice her hands are red, raw, and bleeding. She explains that she washes all her clothes in bleach, and uses the chemical to clean her hands several times a day. She expresses the need to rid herself of all germs. While detailing her plan of care, you inform her of the importance of bacteria to the health and well-being of not only humans but our planet as well. -Microorganisms have inhabited the Earth for billions of years,and can be found inhabiting a variety of environments.In fact,microbes performing oxygenic photosynthesis led to the oxygenation of early Earth's atmosphere.These ancient organisms were
