1. Which of the following is an example of a nonpolar solvent?

• A. Water
• B. Ethanol
• C. Acetone
• D. Hydrochloric acid

Correct answer: B

Rationale: Rationale: - Water (option A) is a polar solvent due to its uneven distribution of charge, with the oxygen atom being partially negative and the hydrogen atoms being partially positive. - Ethanol (option B) is a nonpolar solvent because it has a symmetrical molecular structure that does not result in significant charge separation. - Acetone (option C) is a polar solvent as it contains a carbonyl group that results in a partial negative charge on the oxygen atom. - Hydrochloric acid (option D) is a polar solvent due to the presence of the highly electronegative chlorine atom, which results in a partial negative charge.

2. Stephanie is a new Staff Educator of a private tertiary hospital. She conducts orientation

• A. Organizational structure
• B. Policy
• C. Job description
• D. Manual of procedures

Correct answer: D

Rationale: The correct answer is D, 'Manual of procedures.' During orientation, Stephanie as a Staff Educator would likely refer to the manual of procedures to provide new employees with detailed instructions on how to perform their job duties. This manual outlines the specific procedures, protocols, and guidelines that employees are expected to follow within the organization. It serves as a valuable resource for new hires to understand the standard operating procedures and expectations within the hospital setting, making it a crucial document to reference during orientation.

3. In meiosis, how many divisions occur, and how many daughter cells are produced?

• A. One division, two daughter cells
• B. Two divisions, four daughter cells
• C. Four divisions, eight daughter cells
• D. Eight divisions, sixteen daughter cells

Correct answer: B

Rationale: Rationale: In meiosis, there are two divisions: meiosis I and meiosis II. During meiosis I, homologous chromosomes separate, resulting in two daughter cells with half the number of chromosomes as the parent cell. In meiosis II, sister chromatids separate, resulting in a total of four daughter cells, each with a haploid set of chromosomes. Therefore, meiosis involves two divisions and produces four daughter cells.

4. Which of the following is NOT a function of the integumentary system?

• A. Regulation of body temperature
• B. Protection from pathogens
• C. Synthesis of vitamin D
• D. Production of digestive enzymes

Correct answer: D

Rationale: The correct answer is D: "Production of digestive enzymes." The integumentary system primarily consists of the skin, hair, nails, and glands. Its main functions include regulating body temperature through processes like sweating and shivering, protecting the body from pathogens and external threats, and synthesizing vitamin D when exposed to sunlight. However, the production of digestive enzymes is not a function of the integumentary system. Digestive enzymes are primarily produced by organs such as the pancreas and salivary glands to aid in the breakdown of food in the digestive system, which is separate from the functions of the integumentary system.

5. What property of a wave remains unchanged when it passes from one medium to another with the same speed?

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

Correct answer: d

Rationale: The speed of a wave remains constant when passing from one medium to another with the same speed.

6. Which type of orbital can hold a maximum of 10 electrons?

• A. s orbital
• B. p orbital
• C. d orbital
• D. f orbital

Correct answer: D

Rationale: Each f orbital can hold up to 2 electrons, and there are 5 f orbitals, totaling a maximum of 10 electrons.
