1. Which type of white blood cell directly attacks and destroys pathogens like bacteria and viruses?

A. Neutrophils
B. Lymphocytes
C. Monocytes
D. Eosinophils

Correct answer: A

Rationale: The correct answer is A: Neutrophils. Neutrophils are a type of white blood cell that plays a crucial role in the innate immune response by directly attacking and destroying pathogens like bacteria and viruses. They are the most abundant type of white blood cell and are known for their rapid response to infections. Neutrophils work by engulfing and digesting pathogens through a process called phagocytosis. Lymphocytes (option B) are involved in adaptive immunity, producing antibodies and coordinating immune responses. Monocytes (option C) differentiate into macrophages and dendritic cells, playing a role in phagocytosis and antigen presentation. Eosinophils (option D) are primarily involved in combating parasitic infections and allergic reactions, not directly attacking bacteria and viruses.

2. What are chromosomes made of?

A. DNA and RNA
B. DNA and proteins
C. Proteins and carbohydrates
D. DNA only

Correct answer: B

Rationale: Rationale: Chromosomes are structures found in the nucleus of cells that contain genetic material. They are made up of DNA (deoxyribonucleic acid), which carries the genetic information, and proteins that help in the organization and packaging of the DNA. While RNA is involved in various cellular processes, it is not a major component of chromosomes. Carbohydrates are not a significant component of chromosomes. Therefore, the most accurate answer is B) DNA and proteins.

3. What is the SI unit of measurement for momentum?

A. Newton (N)
B. Kilogram-meter per second (kgÂ·m/s)
C. Joule (J)
D. Newton-second (NÂ·s)

Correct answer: b

Rationale: Momentum is measured in kilogram-meter per second (kgÂ·m/s).

4. What is the correct way to punctuate the following sentence: "She asked me if I wanted to go to the movies with her"?

A. She asked me, if I wanted to go to the movies with her.
B. She asked me: if I wanted to go to the movies with her?
C. She asked me, if I wanted, to go to the movies with her.
D. She asked me if I wanted to go to the movies with her.

Correct answer: D

Rationale: Option D uses a question mark within the quoted material as it is a direct question.

5. What is the end result of mitosis in animal cells?

A. The production of two identical daughter cells
B. The production of four haploid cells
C. The production of a single diploid cell
D. The production of a single haploid cell

Correct answer: A

Rationale: Rationale: Mitosis is a type of cell division that results in the production of two identical daughter cells, each having the same number of chromosomes as the parent cell. This process is essential for growth, repair, and maintenance of multicellular organisms. During mitosis, the replicated chromosomes are separated into two nuclei, and the cell then divides to form two genetically identical daughter cells. Options B, C, and D are incorrect because mitosis does not result in the production of four haploid cells, a single diploid cell, or a single haploid cell.

6. 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.
