Nursing Elites

1. What word is best to substitute for the underlined words in the following sentence? Several nursing students stayed behind after class, but the instructor advised the students to ask questions during office hours.

• A. them
• B. him
• C. they
• D. those

Correct answer: C

Rationale: The word 'they' is the best substitute for the underlined words in the sentence because it refers to the plural noun 'nursing students' and is used to indicate the subject of the sentence. Using 'they' maintains subject-verb agreement and clarity in the sentence. Choice A 'them' is incorrect as it is used for objects, not subjects. Choice B 'him' is singular and does not agree with the plural noun 'nursing students.' Choice D 'those' is also incorrect as it refers to objects, not the subject of the sentence.

2. Select the meaning of the word 'PRN' in the sentence: 'The nurse gave the patient a PRN medication.'

• A. Pinpoint
• B. Relocate
• C. Eradicate
• D. Reduce

Correct answer: D

Rationale: 'PRN' is a medical abbreviation that stands for 'pro re nata,' meaning 'as needed.' In this context, the medication is given to reduce symptoms as they arise. Choice A, 'Pinpoint,' does not align with the meaning of 'PRN.' Choices B and C, 'Relocate' and 'Eradicate,' are unrelated to the concept of 'as needed' medications.

3. When a die is rolled, what is the probability of rolling an odd number?

• A. 16.67%
• B. 33.33%
• C. 75%
• D. 50%

Correct answer: D

Rationale: When a die is rolled, there are 3 odd numbers (1, 3, 5) out of a total of 6 possible outcomes. The probability of rolling an odd number is calculated by dividing the number of favorable outcomes (3) by the total number of outcomes (6), resulting in a probability of 3/6 or 50%. Therefore, the correct answer is D. Choices A, B, and C are incorrect because they do not reflect the correct probability calculation for rolling an odd number on a standard six-sided die.

4. Which of the following describes how a bacterium reproduces?

• A. Mitosis
• B. Meiosis
• C. Binary fission
• D. Cytokinesis

Correct answer: C

Rationale: Bacteria reproduce through a process called 'binary fission.' During binary fission, a bacterium duplicates its DNA and then divides into two identical daughter cells. This method is the primary way bacteria replicate. Choice A, 'Mitosis,' is incorrect because mitosis is a process specific to eukaryotic cells, where the nucleus divides to produce two identical nuclei. Choice B, 'Meiosis,' is incorrect as meiosis is a specialized type of cell division that produces gametes with half the chromosome number. Choice D, 'Cytokinesis,' is not the correct answer as cytokinesis is the physical process of cell division, which occurs after the genetic material has been divided in mitosis or meiosis.

5. The word 'track' as used in the last paragraph of the passage can best be defined as ___________.

• A. Keep a record of
• B. A new attitude
• C. Follow carefully
• D. A paved, circular path

Correct answer: D

Rationale: In the context of the passage, 'track' refers to a 'paved, circular path' for running or walking. The last sentence of the passage encourages people to get off the couch and onto the track, indicating a physical path for exercise. Choice A, 'Keep a record of,' is incorrect as the context does not suggest any relation to recording information. Choice B, 'A new attitude,' is unrelated to the context of exercise and fatigue reduction. Choice C, 'Follow carefully,' does not fit the context of physical activity and energy levels discussed in the passage.
