Nursing Elites

1. Explain how a single gene mutation can lead to multiple phenotypes depending on the organism.

• A. Pleiotropy describes the effect of one gene influencing multiple seemingly unrelated traits.
• B. Epigenetics involves environmental factors modifying gene expression without altering the DNA sequence.
• C. Genetic drift refers to random changes in allele frequencies within a population.
• D. Gene regulation controls the timing and level of gene expression within an organism.

Correct answer: A

Rationale: A single gene mutation can affect different biochemical pathways or developmental processes, leading to a cascade of downstream effects and diverse phenotypic consequences.

2. How can you predict the charge of an ion formed by an element based on its position on the periodic table?

• A. Look for elements with similar atomic weights
• B. Identify the group number, which often indicates the typical ionic charge
• C. Identify the group number, which often indicates the typical ionic charge
• D. Analyze the element's position within the period

Correct answer: B

Rationale: The group number of an element on the periodic table often indicates the typical ionic charge it will form. Elements in the same group tend to have similar chemical properties, including the tendency to gain or lose electrons to achieve a stable electron configuration. This predictable pattern allows us to anticipate the charge of an ion formed by an element based on its position in the periodic table.

3. He raised the issue on giving priority to patient needs. Which of the following offers the best

• A. Assessing nursing needs and problems
• B. Giving instructions on how nursing care needs are to be met
• C. Controlling and evaluating the delivery of nursing care
• D. Assigning safe nurse: patient ratio

Correct answer: A

Rationale: In the context of the sentence 'He raised the issue on giving priority to patient needs,' the best option is 'Assessing nursing needs and problems' (Option A). This option directly aligns with the idea of prioritizing patient needs by first understanding and assessing the specific nursing needs and problems. By assessing these needs, healthcare providers can tailor their care to address the most pressing concerns of the patients, thus effectively giving priority to patient needs. The other options, such as giving instructions on how nursing care needs are to be met (Option B), controlling and evaluating the delivery of nursing care (Option C), and assigning safe nurse: patient ratio (Option D), do not directly address the importance of assessing patient needs as a crucial step in prioritizing patient care. Therefore, Option A is the most suitable choice in this scenario.

4. Which statement accurately describes the relationship between electron configuration and the periodic table?

• A. Elements within the same period have similar electron configurations.
• B. Elements within the same group have similar electron configurations in their outermost shell.
• C. Electron configuration has no influence on an element's position on the periodic table.
• D. The number of electron shells an element has determines its group on the periodic table.

Correct answer: B

Rationale: Elements within the same group have similar electron configurations in their outermost shell. This explains why elements in the same group often share similar chemical properties.

5. Which of the following guidelines should be least considered in formulating objectives for

• A. Written nursing care plan
• B. Holistic approach
• C. Prescribed standards
• D. Staff preferences

Correct answer: D

Rationale: When formulating objectives for a written nursing care plan, staff preferences should be least considered. Objectives should be based on patient needs, evidence-based practice, and professional standards rather than personal preferences of the staff. Prescribed standards ensure quality care and adherence to best practices. A holistic approach considers the whole patient, including physical, emotional, and spiritual aspects. Staff preferences may introduce bias and should not dictate patient care objectives.

6. The sentence "The audience was captivated by the speaker's compelling story" implies that the audience:

• A. Was bored and disinterested.
• B. Found the story confusing.
• C. Was completely absorbed and engaged.
• D. Disagreed with the speaker's message.

Correct answer: C

Rationale: "Captivated" suggests the audience was completely held by the speaker's story.
