Nursing Elites

1. What does the word 'principal' refer to in the following text?

• A. Primary or chief
• B. An acolyte
• C. An individual who provides nurturing
• D. One in a subordinate position

Correct answer: A

Rationale: In this context, the word 'principal' refers to the primary or chief role that Reldresal holds as the principal secretary for private affairs. This term signifies his significant position and authority within the hierarchy. The other choices are incorrect because 'principal' does not mean 'an acolyte' (a follower or assistant), 'an individual who provides nurturing,' or 'one in a subordinate position.'

2. Which of the following correctly orders the layers of the epidermis from most superficial to deepest?

• A. S. spinosum, S. basale, S. corneum, S. granulosum, S. lucidum
• B. S. corneum, S. lucidum, S. granulosum, S. spinosum, S. basale
• C. S. corneum, S. spinosum, S. basale, S. granulosum, S. lucidum
• D. S. basale, S. spinosum, S. granulosum, S. lucidum, S. corneum

Correct answer: B

Rationale: The correct order of the layers of the epidermis from most superficial to deepest is: Stratum corneum, Stratum lucidum, Stratum granulosum, Stratum spinosum, Stratum basale. Choice B, 'S. corneum, S. lucidum, S. granulosum, S. spinosum, S. basale,' provides the accurate layering from the outermost to the innermost layer of the epidermis. Choice A is incorrect as it starts with Stratum spinosum, which is not the most superficial layer. Choice C is incorrect as it places Stratum spinosum before Stratum basale. Choice D is incorrect as it starts with Stratum basale, which is the deepest layer of the epidermis.

3. They were able to reach the deck fastest to get a seat on a lifeboat. Which of the following sentences is written correctly and provides a clear explanation?

• A. Because the majority of survivors came from first class, they were able to reach the deck fastest to get a seat on a lifeboat.
• B. Because of this, the majority of survivors came from first class, as they were able to reach the deck fastest to get a seat on a lifeboat.
• C. Because of this, the majority of survivors came from first class, they were able to reach the deck fastest to get a seat on a lifeboat.
• D. Because of this, the majority of survivors came from first class, as they were able to reach the deck fastest to get a seat on a lifeboat.

Correct answer: B

Rationale: Option B provides a clear and grammatically correct explanation for why the majority of survivors came from first class - they were able to reach the deck fastest to get a seat on a lifeboat. The phrase 'Because of this' properly introduces the reason that follows. In Option A, a comma after 'Because' is unnecessary and disrupts the flow of the sentence. In Option C, 'Because this' is incomplete and lacks proper connection to the subsequent clause. Option D, similar to Option C, lacks clarity due to the absence of a full linking phrase. Therefore, Option B is the best choice as it conveys the explanation effectively and without grammatical errors.

4. What determines the frequency of oscillations in a spring-mass system when the spring is stretched and released?

• A. The mass of the object
• B. The stiffness of the spring
• C. The initial displacement of the object
• D. All of the above

Correct answer: B

Rationale: The frequency of oscillations in a spring-mass system is determined by the stiffness of the spring (spring constant) and the mass of the object. The stiffness of the spring affects how quickly the system oscillates back and forth, while the mass of the object influences the inertia and therefore the frequency. The initial displacement of the object does not impact the frequency of oscillations. Choice A is incorrect because while the mass of the object affects the frequency, it is not the sole determining factor. Choice C is incorrect as the initial displacement affects the amplitude of oscillations, not the frequency. Choice D is incorrect as not all factors listed determine the frequency, making it an incorrect choice.

5. In a study measuring the average hours worked per week by different types of hospital staff (such as nurses and physicians), what are the dependent and independent variables?

• A. The dependent variable is Nurses. The independent variable is Physicians.
• B. The dependent variable is Physicians. The independent variable is Nurses.
• C. The dependent variable is Hospital Staff. The independent variable is Average hours worked per week.
• D. The dependent variable is Average hours worked per week. The independent variable is Hospital Staff.

Correct answer: D

Rationale: In this study, the dependent variable is the 'Average hours worked per week,' as it relies on the different types of 'Hospital Staff' (the independent variable). The amount of time worked per week varies based on the category of staff being considered. Therefore, the correct choice is D. Choices A and B incorrectly assign the dependent and independent variables to specific staff categories (Nurses and Physicians), which are actually different elements within the study. Choice C incorrectly defines the dependent variable as 'Hospital Staff,' when in fact, it is the 'Average hours worked per week' that is dependent on the type of staff.
