1. Which property of a wave represents the distance between two successive identical points on a wave?

• A. Wavelength
• B. Amplitude
• C. Frequency
• D. Period

Correct answer: a

Rationale: Wavelength is the distance between two identical points (like crests or troughs) on a wave.

2. 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.

3. What is the unit of measurement for power?

• A. Joule (J)
• B. Newton (N)
• C. Watt (W)
• D. Kilogram-meter (kg·m)

Correct answer: c

Rationale: Power is measured in watts (W) in the SI unit system.

4. Why are isotopes of the same element chemically similar?

• A. They have the same number of protons.
• B. They have the same number of electrons.
• C. Their chemical properties are identical.
• D. They share the same electron configuration.

Correct answer: A

Rationale: They have the same number of protons. This determines the element's identity and its interactions with other elements, leading to similar chemical behavior, even if the number of neutrons differs.

5. Which of the following guidelines should be least considered in formulating objectives for

• A. Written nursing care plan
• B. Holistic approach
• C. Prescribed standards
• D. Staff preferences

Correct answer: D

Rationale: When formulating objectives for a written nursing care plan, staff preferences should be the least considered guideline. Objectives in a care plan should be based on the patient's needs, evidence-based practices, and prescribed standards of care to ensure quality and effective treatment. Staff preferences may introduce biased decisions that do not align with the best interests of the patient. It is crucial to prioritize holistic care, which considers all aspects of the patient's well-being, and adhere to prescribed standards to provide comprehensive and individualized care. By disregarding staff preferences and focusing on what is best for the patient, healthcare professionals can deliver optimal care that promotes patient outcomes and satisfaction.

6. What is the scientific name for the building blocks of proteins?

• A. Residues
• B. Monomers
• C. Macromolecules
• D. Peptides

Correct answer: B

Rationale: Rationale: - Proteins are made up of long chains of amino acids. - Amino acids are the building blocks of proteins and are considered monomers. - Monomers are the individual units that can be linked together to form larger molecules called polymers. - In the context of proteins, amino acids are the monomers that are linked together through peptide bonds to form polypeptide chains, which then fold into functional proteins. - Residues refer to the specific amino acids within a protein after certain modifications or cleavages have occurred, so it is not the correct term for the building blocks of proteins. - Macromolecules are large molecules made up of smaller subunits, such as proteins, nucleic acids, and carbohydrates, but they are not the specific building blocks of proteins. - Peptides are short chains of amino acids linked by peptide bonds, but they are not the fundamental building blocks of proteins.
