Nursing Elites

1. Which of the following factors can contribute to erectile dysfunction in males?

• A. Diabetes
• B. Cardiovascular disease
• C. Neurological disorders
• D. All of the above

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' Erectile dysfunction in males can be caused by various factors including diabetes, cardiovascular disease, and neurological disorders. Diabetes can lead to nerve damage and reduced blood flow, impacting erectile function. Cardiovascular disease can restrict blood flow to the penis, affecting erections. Neurological disorders can disrupt the signals between the brain and the reproductive system, interfering with the ability to achieve or maintain an erection. Therefore, all of these factors can contribute to erectile dysfunction in males.

2. Which of the following is TRUE about functional nursing?

• A. Concentrates on tasks and activities
• B. Emphasizes use of group collaboration
• C. One-to-one nurse-patient ratio
• D. Provides continuous, coordinated and comprehensive nursing services

Correct answer: B

Rationale: The correct answer is B: "Emphasizes use of group collaboration." Functional nursing is a task-oriented approach where team members specialize in specific tasks or activities. In this model, nurses work together in groups to provide care to a larger number of patients efficiently. This differs from the one-to-one nurse-patient ratio (C) and the continuous, coordinated, and comprehensive nursing services (D). While functional nursing concentrates on tasks (A), the key feature emphasized in this care delivery model is the use of group collaboration to provide care effectively.

3. What is the role of the appendix, a small pouch attached to the large intestine?

• A. To store waste products
• B. To produce immune cells
• C. To secrete digestive enzymes
• D. To regulate blood sugar levels

Correct answer: B

Rationale: While the exact function of the appendix is still debated, it likely houses lymphoid tissue, contributing to the immune system.

4. What is the scientific term for a muscle that helps another muscle perform its action?

• A. Agonist
• B. Antagonist
• C. Synergist
• D. Fixator

Correct answer: C

Rationale: The correct answer is C: Synergist. A synergist muscle is a muscle that assists the prime mover (agonist) in performing its action by stabilizing joints or contributing extra force to the movement. Antagonist muscles oppose the action of the prime mover, while fixator muscles stabilize the origin of the prime mover to allow efficient movement. Understanding the roles of these muscles is essential in comprehending how various muscle groups work together to produce coordinated movements.

5. What is the process by which RNA molecules are modified after transcription but before translation?

• A. Replication
• B. Splicing
• C. Editing
• D. Packaging

Correct answer: B

Rationale: Rationale: A) Replication: Replication is the process by which DNA is copied to produce a new DNA molecule. This process does not involve RNA molecules. B) Splicing: Splicing is the process by which non-coding regions (introns) are removed from pre-mRNA and the remaining coding regions (exons) are joined together to form mature mRNA. This process occurs after transcription but before translation. C) Editing: While RNA molecules can undergo editing processes such as RNA editing, this term is not commonly used to describe the modification of RNA molecules after transcription. D) Packaging: Packaging refers to the process by which DNA is condensed and organized into chromatin in eukaryotic cells. This term is not typically used to describe the modification of RNA molecules after transcription.

6. What cellular process ensures accurate transmission of genetic material during cell division?

• A. Mitosis (somatic cell division)
• B. Meiosis (germ cell division)
• C. Replication (DNA duplication)
• D. Transcription (DNA to RNA conversion)

Correct answer: A

Rationale: Rationale: A) Mitosis is the process by which somatic cells divide to produce two identical daughter cells. During mitosis, the genetic material is accurately replicated and distributed to ensure each daughter cell receives a complete set of chromosomes. This process is crucial for growth, repair, and maintenance of multicellular organisms. B) Meiosis is the type of cell division that occurs in germ cells to produce gametes (sperm and egg cells). While meiosis also involves the transmission of genetic material, it is specifically geared towards generating genetic diversity through recombination and reduction of chromosome number. C) Replication is the process of copying DNA to produce an identical copy. While replication is essential for cell division, it is not the specific process that ensures accurate transmission of genetic material during cell division. D) Transcription is the process by which genetic information in DNA is copied into RNA. Transcription is important for gene ex
