1. 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.

2. 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.

3. What is the momentum of a car with a mass of 1500 kg moving at a speed of 20 m/s?

A. 30,000 kg m/s
B. 1500 kg m/s
C. 20 kg m/s
D. Momentum cannot be determined without knowing the direction of motion.

Correct answer: A

Rationale: Momentum is defined as the product of mass and velocity. Momentum = mass x velocity = 1500 kg x 20 m/s = 30,000 kg m/s.

4. When is work done by a force on an object?

A. Only when the object moves in the direction of the force
B. Only when the object moves against the force
C. Only when the object moves vertically
D. Only when the force is applied for a specific duration

Correct answer: A

Rationale: Work is done by a force on an object when the object moves in the direction of the force. If the object moves perpendicular to the force, no work is done, as the force does not contribute to the displacement of the object. Similarly, if the object moves against the force, work is done because the force is causing the displacement. The vertical movement of the object does not determine whether work is done; it is the direction of the force relative to the object's displacement that matters. The duration of the force application does not affect whether work is done; as long as the force causes the object to move in its direction, work is being done.

5. Which cartilage type allows for smooth movement at joints and absorbs shock?

A. Hyaline cartilage
B. Fibrocartilage
C. Elastic cartilage
D. None of the above

Correct answer: A

Rationale: The correct answer is A: Hyaline cartilage. Hyaline cartilage is the most abundant type of cartilage in the body and is found in the joints, providing a smooth surface for movement. It also acts as a shock absorber, cushioning the joints during activities. Fibrocartilage is found in intervertebral discs and provides strength and support, but it is not as effective at absorbing shock as hyaline cartilage. Elastic cartilage is found in the external ear and epiglottis, providing flexibility and maintaining shape, but it does not have the same shock-absorbing properties as hyaline cartilage. Therefore, hyaline cartilage is the best choice for a cartilage type that allows for smooth movement at joints and absorbs shock.

6. Which of the following statements refers to criteria?

A. Agreed on level of nursing care
B. Characteristics used to measure the level of nursing care
C. Step-by-step guidelines
D. Statement which guide the group in decision making and problem solving

Correct answer: B

Rationale: Criteria are specific characteristics or standards used to evaluate or measure the quality or level of something. In this case, statement B, 'Characteristics used to measure the level of nursing care,' correctly refers to criteria because it highlights the specific attributes that are used to assess the quality or level of nursing care provided. The other options do not directly address the concept of criteria. Option A describes an agreed-upon level of care but does not specifically refer to criteria. Option C describes step-by-step guidelines, which are more related to processes or procedures. Option D mentions statements that guide decision-making and problem-solving, which are not necessarily criteria. Therefore, option B is the most appropriate choice as it directly aligns with the definition and concept of criteria.
