Nursing Elites

1. Select the correct verb to complete the following sentence: 'The girls on the team are excited to play in the championships.'

• A. is
• B. am
• C. are
• D. ares

Correct answer: C

Rationale: The correct verb to use in this sentence is 'are.' In English grammar, when the subject is plural like 'girls,' the correct form of the verb to use is 'are.' Choices A, B, and D are incorrect because 'is' is singular, 'am' is first-person singular, and 'ares' is not a valid verb form in English. Therefore, the correct answer is 'are' to match the plural subject 'girls.'

2. When light interacts with a perfectly smooth surface, like a mirror, the dominant interaction is:

• A. Refraction
• B. Diffraction
• C. Total internal reflection
• D. Specular reflection

Correct answer: D

Rationale: When light interacts with a perfectly smooth surface like a mirror, the dominant interaction is specular reflection. Specular reflection occurs when light rays are reflected off a smooth surface at the same angle as the incident angle, resulting in a clear and sharp reflection. Refraction, which involves the bending of light as it passes from one medium to another, is not the dominant interaction with a perfectly smooth surface. Diffraction, the bending of light waves around obstacles, is not the dominant interaction with smooth surfaces. Total internal reflection occurs when light is reflected back into a medium due to encountering a boundary at an angle greater than the critical angle, but it is not the dominant interaction on a perfectly smooth surface like a mirror.

3. In a graph that shows the number of nurses in various specialties, what is the independent variable?

• A. Anesthesia
• B. Geriatrics
• C. Nurse specialties
• D. Number of nurses

Correct answer: C

Rationale: The independent variable is the variable that is controlled or manipulated in an experiment or study. In this case, the independent variable is the nurse specialties because it is the factor that is being observed and measured to see how it affects the number of nurses in each specialty. The dependent variable, which changes in response to the independent variable, is the number of nurses. Choices A and B are specific nurse specialties and are actually part of the data being measured, not the independent variable itself. Choice D, 'Number of nurses,' is the dependent variable as it is the outcome that is being influenced by the independent variable, which is the nurse specialties.

4. If all of the following sentences appeared in the same paragraph, which sentence would be irrelevant?

• A. I had been doing yoga at least three times a week for the past year.
• B. At first, I walked and ran, though really it was more walking than running.
• C. I had never run a 5k race before, but I decided to try and gave myself six weeks to train for it.
• D. Each day I was able to run a bit further and a bit faster.

Correct answer: A

Rationale: The sentence about doing yoga is irrelevant to the topic of training for a 5k race. The focus of the paragraph is on the process of preparing for the race through running and training, making sentence A unrelated as it discusses a different physical activity.

5. What is the main function of white blood cells?

• A. Transport oxygen
• B. Fight infection
• C. Produce antibodies
• D. Regulate body temperature

Correct answer: B

Rationale: The main function of white blood cells is to fight infection, making choice B the correct answer. White blood cells are a crucial component of the immune system, working to defend the body against pathogens and foreign invaders. Choices A, C, and D are incorrect because white blood cells do not primarily transport oxygen, produce antibodies, or regulate body temperature. While some blood cells are involved in these functions, the primary role of white blood cells is to combat infections and maintain the body's immune response.
