Nursing Elites

1. Which of the following sentences uses the word 'smart' with a negative connotation, rather than a positive connotation or simply the word's denotation?

• A. Eliot's teacher said he was not quite gifted, but too smart for a general class.
• B. Eliot was smart to have studied the day before the test; he got a good grade.
• C. Eliot was identified by his teacher as one of the smart students in her classes.
• D. Eliot got into trouble when he gave a smart answer to his teacher's question.

Correct answer: D

Rationale: In sentence D, the word 'smart' is used with a negative connotation as it describes Eliot getting into trouble for giving a smart answer to his teacher's question. This implies that being smart in this context led to a negative consequence. Choices A, B, and C use 'smart' in a positive or neutral light, highlighting intelligence or wise decisions without any negative implications.

2. Which of the following prefixes would be used to indicate that something is inside or within?

• A. intra–
• B. trans–
• C. anti–
• D. hyper–

Correct answer: A

Rationale: The correct answer is A: "intra–". The prefix "intra-" is used to indicate that something is inside or within. For example, "intracellular" means within a cell, and "intrapersonal" means within oneself. Choice B, "trans–", typically indicates across, beyond, or through, not inside or within. Choice C, "anti–", is used to indicate against or opposed to. Choice D, "hyper–", usually denotes excessive or above normal levels, not inside or within.

3. How many kiloliters are in 147 liters?

• A. 0.147 kiloliters
• B. 1.47 kiloliters
• C. 1,470 kiloliters
• D. 147,000 kiloliters

Correct answer: A

Rationale: To convert liters to kiloliters, divide by 1000 since there are 1000 liters in a kiloliter. Therefore, 147 liters = 0.147 kiloliters. Choice B is incorrect as it incorrectly moves the decimal point. Choices C and D are significantly larger than the correct answer, indicating an incorrect conversion factor used.

4. What is the unit of measurement for momentum?

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

Correct answer: A

Rationale: The correct unit of measurement for momentum is Newton-second (N·s). Momentum is calculated as the product of an object's mass and its velocity. The unit of mass is kilograms (kg) and the unit of velocity is meters per second (m/s). Therefore, the unit of momentum is kilogram-meter per second (kg·m/s). By Newton's second law of motion (F = ma), force is measured in Newtons (N), which is equivalent to kg·m/s². Multiplying the unit of force (N) by the unit of time (s) gives the unit of momentum as Newton-second (N·s). Choice B, Kilogram-meter (kg·m), is incorrect because it represents the unit of work or energy, not momentum. Choice C, Joule (J), is incorrect as it is a unit of energy. Choice D, Meter per second (m/s), is incorrect as it represents velocity alone, not momentum which is a vector quantity involving mass and velocity.

5. What cellular process ensures the 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: Mitosis is the correct answer. 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. Meiosis, on the other hand, is the type of cell division that occurs in germ cells to produce gametes (sperm and egg cells), focusing on genetic diversity through recombination and reduction of chromosome number. Replication is the process of copying DNA to produce an identical copy, essential for cell division but not the specific process ensuring accurate genetic material transmission. Transcription involves copying DNA into RNA, crucial for gene expression but not directly related to the accurate transmission of genetic material during cell division.
