Nursing Elites

1. Describe the concept of inertia in terms of Newton's first law.

• A. Objects in motion tend to remain in motion unless acted upon by an external force
• B. Objects at rest tend to remain at rest unless acted upon by an external force
• C. An object's resistance to a change in its state of motion
• D. The force required to lift an object

Correct answer: c

Rationale: Inertia refers to an object's tendency to maintain its current state of motion (either at rest or in motion) unless acted upon by an external force.

2. Which of the following is an example of a chemical property of matter?

• A. Boiling point
• B. Flammability
• C. Density
• D. Conductivity

Correct answer: b

Rationale: Chemical properties describe how a substance reacts with other substances, such as its ability to burn (flammability) or react with acids or bases.

3. She wants to ensure that every task is carried out as planned. Which of the following tasks is

• A. Instructing the members of the standards committee to prepare policies
• B. Reviewing the existing policies of the hospital
• C. Evaluating the credentials of all nursing staff
• D. Checking if activities conform to schedule

Correct answer: C

Rationale: The correct answer is C because evaluating the credentials of all nursing staff is essential to ensuring that the right individuals are in place to carry out tasks effectively. This task directly contributes to maintaining a high standard of performance and ensuring that the team is qualified for their roles. In contrast, the other options focus on policies, reviews, and schedules, which are important but do not directly address the qualifications and capabilities of the staff responsible for task execution.

4. What is the main function of calcitonin, a hormone produced by the thyroid gland?

• A. Stimulate metabolism and heat production
• B. Increase calcium absorption from the intestines
• C. Enhance bone growth and development
• D. Lower blood calcium levels

Correct answer: D

Rationale: The correct answer is D: 'Lower blood calcium levels.' Calcitonin is a hormone produced by the thyroid gland that helps regulate calcium levels in the blood. It works by inhibiting the breakdown of bone, which in turn lowers the amount of calcium released into the bloodstream. This process helps to decrease blood calcium levels when they are too high. Options A, B, and C are not functions of calcitonin; instead, they are more closely associated with other hormones such as thyroid hormones, vitamin D, and growth hormone, respectively.

5. Two experiments investigating the same phenomenon produce conflicting results. What is the most appropriate next step?

• A. Ignore the conflicting results and focus on the more convincing experiment.
• B. Conduct a combined experiment incorporating elements of both.
• C. Attack the methodology of the experiment with conflicting results.
• D. Accept the more recent experiment as definitively correct.

Correct answer: C

Rationale: When faced with conflicting results from two experiments, it is important to critically evaluate the methodology of both experiments. By examining the experimental design, variables controlled for, sample sizes, and potential sources of bias, one can better understand the reasons behind the discrepancies. Attacking the methodology of the experiment with conflicting results can help identify potential flaws or limitations that may explain the differences in outcomes. This approach allows for a more informed decision on how to proceed, rather than simply ignoring or accepting one set of results over the other.

6. Identify the preposition in the following sentence: The cat jumped over the fence.

• A. cat
• B. jumped
• C. over
• D. the

Correct answer: C

Rationale: Prepositions show the relationship between a noun or pronoun and another word in the sentence. "Over" indicates the position of the cat in relation to the fence.
