Nursing Elites

1. What is the function of ribosomal RNA (rRNA)?

• A. Carries amino acids to the ribosomes
• B. Reads th(a) Carries amino acids to the ribosomes: This is the function of transfer RNA (tRNA), not ribosomal RNA. (b) Reads the genetic code on mRNA: This is the function of the ribosomes as a whole, not just the ribosomal RNA. (d) Controls the rate of protein synthesis: This is a more complex process involving various factors, not solely ribosomal RNA. e genetic code on mRNA
• C. Forms the structural framework of ribosomes
• D. Controls the rate of protein synthesis

Correct answer: C

Rationale: Rationale: Ribosomal RNA (rRNA) plays a crucial role in forming the structural framework of ribosomes, which are the cellular organelles responsible for protein synthesis. Ribosomes consist of both protein and rRNA components, with rRNA providing the structural support necessary for the ribosome to function properly. This structural framework allows the ribosome to interact with messenger RNA (mRNA) and transfer RNA (tRNA) during the process of translation, where the genetic information encoded in mRNA is used to assemble proteins from amino acids. Therefore, the primary function of rRNA is to contribute to the structure and function of ribosomes, rather than directly carrying amino acids, reading the genetic code, or controlling the rate of protein synthesis.

2. During normal breathing, which muscle is the primary driver of inhalation by contracting and flattening to increase the volume of the thoracic cavity?

• A. Diaphragm
• B. Intercostal muscles
• C. Abdominal muscles
• D. Pectoral muscles

Correct answer: A

Rationale: The diaphragm is the primary muscle responsible for inhalation during normal breathing. When the diaphragm contracts and flattens, it increases the volume of the thoracic cavity, creating a negative pressure that allows air to rush into the lungs. The intercostal muscles also play a role in expanding the ribcage to assist with inhalation. However, the diaphragm is the main driver of the breathing process by creating the necessary space for the lungs to expand and fill with air.

3. What is the formula for calculating density?

• A. Density = Volume / Mass
• B. Density = Mass × Volume
• C. Density = Mass / Volume
• D. Density = Volume - Mass

Correct answer: c

Rationale: Density is defined as the mass of a substance divided by its volume. The formula for density is Density = Mass / Volume.

4. Identify the noun clause in the sentence: "My biggest fear is that I wouldn't live life to the fullest."

• A. "My biggest fear"
• B. "that I wouldn't live life to the fullest"
• C. "life"
• D. "the fullest"

Correct answer: B

Rationale: Option B functions as the object of the verb "is," making it a noun clause.

5. 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.

6. Identify the direct object in the following sentence: "She baked a delicious cake for the party."

• A. for the party
• B. delicious
• C. cake
• D. baked

Correct answer: C

Rationale: The direct object receives the action of the verb.
