Nursing Elites

1. A nurse needs to administer 0.8 milliliters of medication. The only available syringe measures in teaspoons. How many teaspoons should the nurse use?

• A. 0.2 teaspoons
• B. 0.4 teaspoons
• C. 0.6 teaspoons
• D. 0.8 teaspoons

Correct answer: B

Rationale: Rationale: 1 milliliter is equivalent to approximately 0.2 teaspoons. Therefore, to find out how many teaspoons are in 0.8 milliliters, we can set up a proportion: 0.8 milliliters * 0.2 teaspoons/1 milliliter = 0.16 teaspoons Since 0.16 teaspoons is not one of the answer choices, we need to convert it to a more practical measurement. The closest option is 0.4 teaspoons, which is the correct answer.

2. How is power related to work and time?

• A. Power = Work ÷ Time
• B. Power = Work × Time
• C. Power = Work + Time
• D. Power = Work - Time

Correct answer: a

Rationale: Power is calculated as the amount of work done or energy transferred per unit of time.

3. The professor explained the concept clearly. What is the past participle of the verb "explain"?

• A. explains
• B. explaining
• C. explained
• D. explanation

Correct answer: C

Rationale: The past participle is used to form verb tenses and passive voice constructions.

4. What is the correct way to write "25th anniversary" as a word?

• A. Twenty-fiveth anniversary
• B. Twenty Fiveth Anniversary
• C. Twenty fifth anniversary
• D. twenty-fifth anniversary

Correct answer: D

Rationale: Ordinals (numbers with "th", "st", "nd", etc.) are generally written as words when used before nouns. Option (d) is correct.

5. Which of the following phases of the cell cycle is characterized by the replication of DNA?

• A. Interphase
• B. Mitosis
• C. Meiosis
• D. Cytokinesis

Correct answer: A

Rationale: Rationale: Interphase is the phase of the cell cycle where the cell spends the majority of its time and is characterized by three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2). During the S phase of interphase, DNA replication occurs, leading to the duplication of the genetic material in the cell. This ensures that each daughter cell produced during cell division receives a complete set of genetic information. Mitosis is the phase of the cell cycle where the replicated DNA is divided equally between two daughter cells, while meiosis is a specialized type of cell division that occurs in sexually reproducing organisms to produce gametes. Cytokinesis is the final stage of the cell cycle where the cytoplasm divides, resulting in two separate daughter cells.

6. What is the role of DNA in evolution?

• A. It stores genetic information that can be passed on to offspring
• B. It allows for mutations that can introduce new variations
• C. It regulates the expression of genes that influence traits
• D. All of the above

Correct answer: D

Rationale: Rationale: A) DNA stores genetic information that is passed on from parents to offspring through the process of reproduction. This genetic information contains instructions for the development and functioning of an organism. B) DNA can undergo mutations, which are changes in the genetic sequence. These mutations can introduce new variations in the DNA, leading to genetic diversity within a population. C) DNA plays a crucial role in regulating the expression of genes. Gene expression determines which proteins are produced in an organism, influencing its traits and characteristics. D) Therefore, DNA is involved in all of the above processes, making it a key factor in evolution by driving genetic variation, inheritance, and gene expression.
