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. Why are noble gas elements generally unreactive?

• A. They are too large and cannot form bonds easily.
• B. They lack valence electrons in their outermost shell.
• C. They have strong bonds within their own molecules.
• D. They have already achieved stable electron configurations.

Correct answer: D

Rationale: They have already achieved stable electron configurations. With completely filled outermost shells, noble gas elements have no need to gain or lose electrons, minimizing their tendency to participate in chemical reactions.

3. Which structure in the respiratory system serves as the "windpipe" that conducts air from the larynx to the bronchi?

• A. Trachea
• B. Larynx
• C. Bronchi
• D. Alveoli

Correct answer: A

Rationale: The correct answer is A: Trachea. The trachea, also known as the windpipe, is a tube-like structure in the respiratory system that connects the larynx to the bronchi. It serves as the main airway for the passage of air into and out of the lungs. The larynx is commonly known as the voice box and is responsible for producing sound. The bronchi are the two branches that stem from the trachea and lead to the lungs, where they further divide into smaller airways. The alveoli are tiny air sacs in the lungs where gas exchange occurs. Therefore, the trachea is the correct answer as it directly conducts air from the larynx to the bronchi.

4. What is the process by which the body maintains a relatively constant blood pH level, even with changes in blood carbon dioxide concentration?

• A. Cellular respiration
• B. Gas exchange
• C. Buffering system
• D. Deoxygenation

Correct answer: C

Rationale: The correct answer is C: Buffering system. The body maintains a relatively constant blood pH level through the buffering system, which consists of chemical substances that can absorb excess hydrogen ions or release hydrogen ions to adjust pH levels. This system helps prevent drastic changes in blood pH even when there are fluctuations in blood carbon dioxide concentration. Cellular respiration and gas exchange are processes related to obtaining and utilizing oxygen, while deoxygenation refers to the removal of oxygen from a substance. Therefore, the buffering system is specifically responsible for regulating blood pH levels in response to changes in carbon dioxide concentration.

5. What property of a substance remains constant regardless of its location in the universe?

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: a

Rationale: Mass is an intrinsic property of matter that remains constant regardless of its location in the universe.

6. What is the main difference between a telescope and a microscope?

• A. Telescopes magnify distant objects, while microscopes magnify small objects.
• B. Telescopes use lenses, while microscopes use mirrors.
• C. Telescopes collect light, while microscopes emit light.
• D. They both magnify objects but serve different purposes.

Correct answer: A

Rationale: While both instruments magnify objects, telescopes are designed to observe distant objects, while microscopes are used to magnify tiny objects close to the observer.
