Nursing Leadership and Management

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

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.

2. Which sentence uses the word "literally" correctly?

Correct answer: B

Rationale: Option B uses "literally" to emphasize the magnitude of work, not to exaggerate a simple action.

3. What is the main idea of the following passage: "The internet has revolutionized communication, allowing people to connect instantly from anywhere in the world. Social media platforms, like Facebook and Twitter, have further amplified this connectivity, enabling individuals to share information and ideas on a global scale."

Correct answer: C

Rationale: The passage emphasizes the transformative impact of the internet and social media on communication.

4. The muscular diaphragm plays a vital role in respiration. When it contracts, it:

Correct answer: A

Rationale: The diaphragm is a crucial muscle involved in respiration. When the diaphragm contracts, it flattens and moves downwards, increasing the volume in the thoracic cavity. This expansion creates a negative pressure in the lungs, causing air to rush in during inhalation. Therefore, option A, 'Increases lung volume for inhalation,' is the correct answer. The diaphragm's contraction facilitates the breathing process by creating space for the lungs to expand and take in air, making it essential for proper respiration.

5. What is the process of copying DNA called?

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. What is the process of transporting molecules across the cell membrane against a concentration gradient called?

Correct answer: C

Rationale: Rationale: A) Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, which does not require energy input. B) Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. C) Active transport is the process of transporting molecules across the cell membrane against a concentration gradient, requiring energy in the form of ATP to move substances from an area of lower concentration to an area of higher concentration. D) Facilitated diffusion is a type of passive transport that involves the use of transport proteins to move molecules across the cell membrane from an area of higher concentration to an area of lower concentration, without the need for energy input.
