Nursing Elites

1. The author's attitude towards history seems to be

• A. indifferent and neutral, presenting it as an objective field of study.
• B. critical and dismissive, questioning its practical applicability in the present.
• C. enthusiastic and optimistic, highlighting its potential to guide the future.
• D. pessimistic and cautious, emphasizing the risk of repeating past mistakes.

Correct answer: C

Rationale: The passage's overall tone highlights the value and utility of history, showcasing its potential to inspire and guide us, suggesting an optimistic and encouraging view.

2. Which of the following is NOT a mechanism that can directly cause evolution by natural selection?

• A. Mutations in genes
• B. Differential survival and reproduction based on traits
• C. Inheritance of acquired characteristics (like strong muscles from working out)
• D. Competition for resources in an environment

Correct answer: C

Rationale: Rationale: A) Mutations in genes can introduce new genetic variations into a population, which can be acted upon by natural selection. B) Differential survival and reproduction based on traits is a key component of natural selection, as individuals with advantageous traits are more likely to survive and pass on their genes to the next generation. C) Inheritance of acquired characteristics, also known as Lamarckism, is not a mechanism of evolution by natural selection. Traits acquired during an individual's lifetime (such as strong muscles from working out) are not passed on to offspring. D) Competition for resources in an environment can drive natural selection by favoring individuals with traits that help them better compete for limited resources. Therefore, the correct answer is C) Inheritance of acquired characteristics (like strong muscles from working out), as it is not a mechanism that can directly cause evolution by natural selection.

3. What is the main function of transition words and phrases in writing?

• A. To add unnecessary embellishments and fluff.
• B. To emphasize specific words or phrases in the text.
• C. To connect ideas smoothly and guide the reader's flow.
• D. To introduce opposing viewpoints and counterarguments.

• A. By the time I arrived, the party had already begun.
• B. I wish I had studied harder for the exam.
• C. We will have finished the project by Monday.
• D. She had been waiting for hours before he finally showed up.

Rationale: Option A expresses an action ("party began") completed before another past action ("I arrived").

5. Which of the following is responsible for generating the electrical impulses that regulate the heartbeat?

• A. Aorta
• B. Pulmonary veins
• C. Coronary arteries
• D. Sinoatrial (SA) node

Correct answer: D

Rationale: The correct answer is D: Sinoatrial (SA) node. The SA node, also known as the heart's natural pacemaker, is responsible for generating the electrical impulses that regulate the heartbeat. These impulses initiate each heartbeat by causing the atria to contract. The other options, Aorta, Pulmonary veins, and Coronary arteries, are important structures in the cardiovascular system but are not directly responsible for generating the electrical impulses that regulate the heartbeat.

6. Functional nursing has some advantages, which one is an EXCEPTION?

• A. Psychological and sociological needs are emphasized.
• B. Great control of work activities.
• C. Most economical way of delivering nursing services.
• D. Workers feel secure in dependent role

Correct answer: B

Rationale: Functional nursing is a task-oriented approach where each nurse is assigned specific duties, leading to efficient task completion but often resulting in a lack of holistic care. While functional nursing may provide great control over work activities and can be cost-effective due to specialization, it does not emphasize psychological and sociological needs, which is a significant disadvantage. Additionally, the dependent role that workers feel in functional nursing can lead to disempowerment and hinder professional growth and autonomy. Therefore, option A, 'Psychological and sociological needs are emphasized,' is the exception among the advantages of functional nursing.
