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. What is the significance of the nuclear envelope breaking down during mitosis?

• A. It allows the chromosomes to condense and become visible.
• B. It allows the spindle apparatus to form and attach to the chromosomes.
• C. It allows the sister chromatids to separate.
• D. It allows the nuclear material to be evenly distributed to the daughter cells.

Correct answer: B

Rationale: Rationale: A) The breakdown of the nuclear envelope does not directly cause the chromosomes to condense and become visible. Chromosome condensation is a separate process that occurs before mitosis begins. B) The breakdown of the nuclear envelope is crucial for the formation of the spindle apparatus, a structure made of microtubules that helps separate the chromosomes during cell division. The spindle apparatus attaches to the chromosomes and helps move them to opposite poles of the cell. C) The separation of sister chromatids occurs during anaphase, which is facilitated by the spindle apparatus. The breakdown of the nuclear envelope is not directly involved in this process. D) The even distribution of nuclear material to daughter cells is achieved through the movement of chromosomes by the spindle apparatus, which is made possible by the breakdown of the nuclear envelope.

3. What property of a substance remains constant regardless of changes in its shape or size?

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

Correct answer: a

Rationale: Mass remains constant regardless of changes in an object's shape or size.

4. The statement, “The Good Shepherd Medical Center aims to provide patient-centered care in

• A. Vision
• B. Goal
• C. Philosophy
• D. Mission

Correct answer: A

Rationale: The correct answer is A: "Vision." A vision statement describes the desired future state or long-term goal of an organization. It outlines the aspirations and purpose of the organization, such as providing patient-centered care in this case. Vision statements are forward-looking and inspirational, guiding the organization towards achieving its ultimate objectives. In contrast, a goal is a specific, measurable, and achievable target within a set timeframe. A philosophy is a set of beliefs or guiding principles, while a mission statement defines the organization's core purpose and focus. Therefore, the statement about providing patient-centered care aligns with the concept of a vision statement.

5. In an SN2 reaction, the rate of the reaction is affected by

• A. Only the concentration of the nucleophile
• B. Only the concentration of the electrophile
• C. Neither the concentration of the nucleophile nor the electrophile
• D. Both the concentration of the nucleophile and the electrophile

Correct answer: D

Rationale: In an SN2 reaction, the rate of the reaction is affected by both the concentration of the nucleophile and the electrophile. This is because in an SN2 reaction, the nucleophile directly attacks the electrophilic center, leading to the formation of the product. A higher concentration of nucleophile increases the chances of successful collisions with the electrophile, thereby increasing the reaction rate. Similarly, a higher concentration of the electrophile provides more reaction sites for the nucleophile to attack, also increasing the rate of the reaction. Therefore, both the nucleophile and electrophile concentrations play crucial roles in determining the rate of an SN2 reaction.

6. What is the process of converting lactic acid back into pyruvate called?

• A. Glycolysis
• B. Gluconeogenesis
• C. Cori cycle
• D. Oxidative phosphorylation

Correct answer: C

Rationale: Rationale: A) Glycolysis is the process of breaking down glucose into pyruvate. B) Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources. C) The Cori cycle is the process by which lactic acid produced by anaerobic metabolism in muscles is transported to the liver and converted back into glucose or pyruvate. D) Oxidative phosphorylation is the process by which ATP is synthesized using energy derived from the transfer of electrons in the electron transport chain.
