Nursing Leadership and Management
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. When proofreading your writing, focus on:
- A. Changing the wording to sound more original.
- B. Ignoring minor grammatical errors like typos.
- C. Checking for clarity, consistency, and overall flow.
- D. Replacing common words with thesaurus alternatives.
Correct answer: C
Rationale: Proofreading involves correcting errors, refining sentence structure, and ensuring the writing achieves its purpose, clarity, and consistency.
3. After exposure to a pathogen, the immune system develops memory. What type of immune cell is responsible for this immunological memory?
- A. B cells
- B. T cells (specifically memory T cells)
- C. Phagocytes
- D. Natural killer cells
Correct answer: B
Rationale: The correct answer is A: "B cells." B cells are responsible for generating immunological memory after exposure to a pathogen. When B cells encounter a pathogen, they differentiate into memory B cells, which can quickly recognize and respond to the pathogen upon subsequent exposure. These memory B cells are crucial for mounting a faster and more effective immune response, leading to a quicker clearance of the pathogen. T cells, phagocytes, and natural killer cells play important roles in the immune response, but specifically, memory B cells are responsible for immunological memory.
4. Which of the following is the primary function of the cell membrane?
- A. To provide structural support for the cell
- B. To transport substances in and out of the cell
- C. To synthesize proteins and lipids
- D. To store genetic material
Correct answer: B
Rationale: Rationale: The cell membrane, also known as the plasma membrane, plays a crucial role in regulating the movement of substances in and out of the cell. It is selectively permeable, meaning it allows certain molecules to pass through while blocking others. This function is essential for maintaining the internal environment of the cell and ensuring that necessary nutrients can enter the cell while waste products and other substances can exit. While the cell membrane does provide some structural support for the cell, its primary function is to control the transport of substances. The synthesis of proteins and lipids primarily occurs in other cellular organelles such as the endoplasmic reticulum and Golgi apparatus, while storing genetic material is the function of the nucleus.
5. What is the process of copying DNA called?
- A. Transcription
- B. Translation
- C. Replication
- D. Mutation
Correct answer: C
Rationale: Rationale: A) Transcription is the process of creating an RNA copy of a segment of DNA. It involves the synthesis of mRNA from a DNA template. B) Translation is the process of synthesizing a protein from an mRNA template. It involves the conversion of the mRNA sequence into a sequence of amino acids. C) Replication is the process of copying DNA to produce an identical copy. During replication, the DNA double helix unwinds and each strand serves as a template for the synthesis of a new complementary strand, resulting in two identical DNA molecules. D) Mutation refers to a change in the DNA sequence that can result from errors during replication, exposure to mutagens, or other factors. While mutations can occur during replication, the process of copying DNA itself is called replication.
6. A closed system in ecology is one that:
- A. Exchanges energy but not matter
- B. Exchanges both energy and matter
- C. Exchanges neither energy nor matter
- D. Recycles nutrients efficiently
Correct answer: A
Rationale: Rationale: In ecology, a closed system is one that does not exchange matter with its surroundings but can exchange energy. This means that while energy can enter or leave the system, the amount of matter within the system remains constant. This definition aligns with option A, making it the correct answer. Options B and C are incorrect because a closed system does not exchange matter, and option D is not directly related to the definition of a closed system in ecology.
