Chemistry
1. Which of the following is an example of a secondary alcohol?
- A. Methanol
- B. Ethanol
- C. Isopropanol
- D. Butanol
Correct answer: C
Rationale: Isopropanol is an example of a secondary alcohol, as the hydroxyl group is attached to a carbon atom that is bonded to two other carbon atoms. The other choices are primary alcohols.
2. What cellular process ensures accurate transmission of genetic material during cell division?
- A. Mitosis (somatic cell division)
- B. Meiosis (germ cell division)
- C. Replication (DNA duplication)
- D. Transcription (DNA to RNA conversion)
Correct answer: A
Rationale: Rationale: A) Mitosis is the process by which somatic cells divide to produce two identical daughter cells. During mitosis, the genetic material is accurately replicated and distributed to ensure each daughter cell receives a complete set of chromosomes. This process is crucial for growth, repair, and maintenance of multicellular organisms. B) Meiosis is the type of cell division that occurs in germ cells to produce gametes (sperm and egg cells). While meiosis also involves the transmission of genetic material, it is specifically geared towards generating genetic diversity through recombination and reduction of chromosome number. C) Replication is the process of copying DNA to produce an identical copy. While replication is essential for cell division, it is not the specific process that ensures accurate transmission of genetic material during cell division. D) Transcription is the process by which genetic information in DNA is copied into RNA. Transcription is important for gene ex
3. She conducts a 6-month performance review session with a staff member. Which of the
- A. She asks another nurse to attest the session as a witness.
- B. She informs the staff that she may ask another nurse to read the appraisal before the session is
- C. She tells the staff that the session is manager-centered.
- D. The session is private between the two members.
Correct answer: C
Rationale: Option C is the correct answer because telling the staff that the session is manager-centered indicates that the focus will be on the manager's evaluation and feedback rather than promoting a collaborative and transparent review process. This approach can lead to a one-sided assessment and may not foster open communication or growth opportunities for the staff member. Options A and B involve bringing in another nurse, which could potentially compromise the privacy and effectiveness of the performance review. Option D, stating that the session is private between the two members, does not address the issue of the session being manager-centered. Therefore, option C is the most appropriate choice to highlight the importance of a balanced and inclusive performance review process.
4. The fluid-filled sacs that cushion the brain within the skull are called:
- A. Meninges
- B. Cerebrospinal fluid
- C. Dura mater
- D. Arachnoid mater
Correct answer: B
Rationale: The correct answer is B: Cerebrospinal fluid. Cerebrospinal fluid is a clear, colorless fluid that surrounds the brain and spinal cord, acting as a cushion to protect the central nervous system from injury. Meninges (Option A) are the protective membranes that cover the brain and spinal cord, while the dura mater (Option C) and arachnoid mater (Option D) are specific layers of the meninges. However, cerebrospinal fluid is the fluid-filled sac that directly cushions the brain within the skull, making it the most appropriate answer for this question.
5. Which of the following is an example of a decomposition reaction?
- A. 2H2 + O2 → 2H2O
- B. CaCO3 → CaO + CO2
- C. 2Na + Cl2 → 2NaCl
- D. N2 + 3H2 → 2NH3
Correct answer: b
Rationale: Decomposition reactions involve the breakdown of a compound into simpler substances.
6. Which word best synonyms with the word "elated"?
- A. Angry
- B. Sad
- C. Excited
- D. Confused
Correct answer: C
Rationale: "Elated" and "excited" both convey feelings of happiness and enthusiasm.
