Nursing Elites

1. On the other hand, Ms. Castro notices that the Chief Nurse Executive has charismatic

• A. Possesses inspirational quality that makes followers gets attracted of him and regards
• B. Acts as he does because he expects that his behavior will yield positive results
• C. Uses visioning as the core of his leadership
• D. Matches his leadership style to the situation at hand.

Correct answer: D

Rationale: The correct answer is D because matching leadership style to the situation at hand is a key aspect of effective leadership. Being able to adapt and adjust leadership approaches based on the specific circumstances and needs of a situation can lead to better outcomes and success. In this scenario, the Chief Nurse Executive's ability to tailor his leadership style to different situations is likely to contribute to his effectiveness in managing various challenges and leading the team effectively.

2. How does kinetic energy change when the velocity of an object is doubled?

• A. Kinetic energy is halved
• B. Kinetic energy quadruples
• C. Kinetic energy doubles
• D. Kinetic energy remains the same

Correct answer: b

Rationale: Kinetic energy is directly proportional to the square of the velocity of an object.

3. Nuclear fusion powers the sun and other stars. What is the main obstacle to achieving controlled nuclear fusion on Earth for energy production?

• A. Lack of suitable materials to handle high temperatures and pressures.
• B. Limited availability of fusion fuels like deuterium and tritium.
• C. Difficulty in containing the plasma where fusion occurs.
• D. All of the above.

Correct answer: D

Rationale: The main obstacle to achieving controlled nuclear fusion on Earth for energy production involves a combination of factors. A) Lack of suitable materials to handle high temperatures and pressures is a significant challenge due to the extreme conditions required for fusion reactions. B) Limited availability of fusion fuels like deuterium and tritium can pose a constraint on the scalability and sustainability of fusion energy. C) Difficulty in containing the plasma where fusion occurs is another critical issue as plasma instabilities and heat losses can hinder the efficiency of fusion reactions. Therefore, all of the options (A, B, and C) contribute to the challenges in achieving controlled nuclear fusion for energy production on Earth.

4. How can you differentiate between a bacterial and viral infection based solely on symptoms?

• A. It's impossible to differentiate solely on symptoms.
• B. Bacterial infections typically respond well to antibiotics, while viral infections don't.
• C. Bacterial infections usually cause fever, while viral infections don't.
• D. Viral infections often present with respiratory symptoms like a cough, while bacterial infections don't.

Correct answer: B

Rationale: Option B is the correct answer because bacterial infections are typically treated with antibiotics, while viral infections do not respond to antibiotics. This is a key differentiating factor between the two types of infections. While some symptoms may overlap between bacterial and viral infections, the response to antibiotic treatment is a reliable indicator. It's important to note that solely relying on symptoms to differentiate between bacterial and viral infections can be challenging since many symptoms can be similar. Therefore, the response to antibiotics is a more definitive way to distinguish between the two types of infections.

5. There are times when Katherine evaluates her staff as she makes her daily rounds. Which of

• A. The staff member is observed in natural setting.
• B. Incidental confrontation and collaboration is allowed.
• C. The evaluation is focused on objective data systematically.
• D. The evaluation may provide valid information for compilation of a formal report.

Correct answer: A

Rationale: The correct answer is A: 'The staff member is observed in a natural setting.' This option is the most appropriate because it aligns with the concept of naturalistic observation, where behavior is observed in its natural environment without interference or manipulation. In this scenario, Katherine is observing her staff during her daily rounds without any alterations to their behavior or environment. This allows for a more authentic and unbiased assessment of their performance. Options B, C, and D are not as relevant to the concept of naturalistic observation and do not accurately describe the situation presented in the question.

6. The primary function of the atrioventricular (AV) node within the heart is to:

• A. Generate the electrical impulse for contraction (pacemaker function)
• B. Transmit the electrical impulse from atria to ventricles, regulating the timing of contraction.
• C. Increase blood pressure within the ventricles during systole.
• D. Separate oxygenated and deoxygenated blood flow in the heart.

Correct answer: B

Rationale: The correct answer is B: "Transmit the electrical impulse from atria to ventricles, regulating the timing of contraction." The AV node acts as a gateway between the atria and ventricles, ensuring a coordinated and sequential contraction of the heart chambers. It delays the conduction of electrical impulses to allow the atria to fully contract before the ventricles contract, facilitating efficient blood pumping. Options A, C, and D are incorrect because the primary role of the AV node is not to generate electrical impulses, increase blood pressure, or separate blood flow based on oxygenation status. Understanding the AV node's function is crucial in comprehending the heart's electrical conduction system.
