1. He raised the issue on giving priority to patient needs. Which of the following offers the best

A. Assessing nursing needs and problems
B. Giving instructions on how nursing care needs are to be met
C. Controlling and evaluating the delivery of nursing care
D. Assigning safe nurse: patient ratio

Correct answer: A

Rationale: In the context of the sentence 'He raised the issue on giving priority to patient needs,' the best option is 'Assessing nursing needs and problems' (Option A). This option directly aligns with the idea of prioritizing patient needs by first understanding and assessing the specific nursing needs and problems. By assessing these needs, healthcare providers can tailor their care to address the most pressing concerns of the patients, thus effectively giving priority to patient needs. The other options, such as giving instructions on how nursing care needs are to be met (Option B), controlling and evaluating the delivery of nursing care (Option C), and assigning safe nurse: patient ratio (Option D), do not directly address the importance of assessing patient needs as a crucial step in prioritizing patient care. Therefore, Option A is the most suitable choice in this scenario.

2. A new invention claims to solve the energy crisis. What criteria should you use to evaluate this claim?

A. The inventor's qualifications and credentials.
B. The technology's cost-effectiveness and affordability.
C. Evidence of independent testing and scientific validation.
D. Testimonials from celebrities and public figures.

Correct answer: C

Rationale: When evaluating a claim about solving the energy crisis, it is crucial to look for evidence of independent testing and scientific validation. This ensures that the technology has been rigorously assessed and verified by experts in the field, providing credibility to the invention's effectiveness. Testimonials from celebrities and public figures (option D) may not provide reliable information about the technology's actual capabilities. The inventor's qualifications and credentials (option A) are important but do not guarantee the technology's success. Cost-effectiveness and affordability (option B) are significant factors but should be considered alongside scientific validation to assess the overall impact and feasibility of the invention.

3. A person pushes a box across a floor with a constant force. The box eventually comes to a stop due to friction. What happens to the work done by the person?

A. It increases as the box moves further.
B. It decreases as the box slows down.
C. It remains constant throughout the motion.
D. It becomes zero once the box stops.

Correct answer: C

Rationale: Work is defined as force multiplied by distance, and as long as the force remains constant, the work done increases proportionally to the distance moved, even if the box slows down due to friction.

4. Which property of a substance measures the amount of matter per unit volume?

A. Density
B. Mass
C. Weight
D. Volume

Correct answer: a

Rationale: Density is the property that measures the amount of matter (mass) per unit volume of a substance. It is calculated as mass divided by volume.

5. What is the "lock-and-key" model?

A. Protein folding
B. Enzyme-substrate interaction
C. Muscle contraction
D. Blood clotting

Correct answer: B

Rationale: Rationale: The "lock-and-key" model is a concept used to describe the specificity of the interaction between enzymes and their substrates. In this model, the enzyme's active site is like a lock that can only be opened by the specific substrate molecule, which acts as the key. This specific binding ensures that enzymes catalyze specific reactions and do not interact with other molecules indiscriminately. Protein folding (option A) refers to the process by which a protein adopts its functional three-dimensional structure, but it is not specifically related to the lock-and-key model. Muscle contraction (option C) and blood clotting (option D) are biological processes that involve complex mechanisms but are not directly related to the lock-and-key model of enzyme-substrate interaction.

6. What is the recommended daily fiber intake for adults?

A. 10 grams
B. 25 grams
C. 35 grams
D. 50 grams

Correct answer: B

Rationale: Rationale: The recommended daily fiber intake for adults is around 25 grams for women and 38 grams for men. Fiber is essential for maintaining a healthy digestive system, preventing constipation, and reducing the risk of chronic diseases such as heart disease and diabetes. Consuming an adequate amount of fiber can also help with weight management and promote overall well-being. Therefore, option B is the most appropriate answer based on the recommended daily intake guidelines for adults.
