1. What is the correct electron configuration for nitrogen?

• A. 1s² 2s²
• B. 1s² 2s² 2p²
• C. 1s² 2s² 2p³
• D. 1s² 2s² 2p⁴

Correct answer: C

Rationale: The electron configuration of nitrogen is determined by its atomic number, which is 7. Nitrogen has 7 electrons. Following the order of filling orbitals, the electron configuration for nitrogen is 1s² 2s² 2p³. This means the first energy level is filled with 2 electrons in the 1s orbital, the second energy level is filled with 2 electrons in the 2s orbital, and 3 electrons in the 2p orbital. Each orbital can hold a specific number of electrons, and nitrogen, with its 7 electrons, fits this configuration. Choice A is incorrect because it does not account for all the electrons in the nitrogen atom. Choice B is incorrect as it only represents 6 electrons, not the 7 electrons in nitrogen. Choice D is incorrect as it represents 8 electrons, which is not the correct electron configuration for nitrogen.

2. Select the word or phrase that makes this sentence grammatically correct: 'Sometimes, the condition ____ with an unusual symptom—vertigo.'

• A. presence
• B. presents
• C. present
• D. prescience

Correct answer: B

Rationale: 'Presents' is the correct choice here. The sentence requires a verb that indicates the condition appearing with a symptom. In medical terminology, when a condition 'presents' with a symptom, it means that the symptom is a noticeable feature or indication of the condition. Therefore, 'presents' is the appropriate verb to describe how the condition manifests itself with vertigo. The other options do not fit the grammatical structure of the sentence.

3. How many different types of nucleotides are there in DNA?

• A. one
• B. two
• C. four
• D. eight

Correct answer: C

Rationale: The correct answer is 'C: four.' DNA is composed of four different types of nucleotides: adenine, thymine, guanine, and cytosine. These nucleotides pair up in specific combinations to form the genetic code. Choices 'A: one,' 'B: two,' and 'D: eight' are incorrect because DNA consists of a set of four distinct nucleotides, not one, two, or eight.

4. What does Labile mean?

• A. Stable
• B. Changing rapidly and often
• C. Unchanging
• D. Rarely changing

Correct answer: B

Rationale: Labile means something that changes rapidly and often. In this context, 'Stable' (Choice A) is the opposite of labile, 'Unchanging' (Choice C) and 'Rarely changing' (Choice D) do not capture the essence of labile. Labile is specifically used to describe something that is easily altered, constantly changing, or unstable, hence the most suitable choice is 'Changing rapidly and often' (Choice B).

5. Select the word in the following sentence that is not used correctly. Collecting personal and vital data is one of the roles of an intake nurse.

• A. personal
• B. vital
• C. datum
• D. roles

Correct answer: C

Rationale: The word 'datum' is singular, and the correct plural form of 'datum' is 'data.' Therefore, the sentence should use 'data' instead of 'datum' to be grammatically correct. In the sentence provided, 'datum' should be replaced with 'data' to maintain proper grammar and syntax. Choices A, B, and D are used correctly in the sentence, so they are not the correct answer.
