Correct Answer: B

Rationale: In the context of the sentence provided, 'parameters' refer to the limits or boundaries set by medical ethics that dictate the nurse's actions. This term does not directly relate to laws (choice A), common sense (choice C), or structure (choice D) in this context. The correct answer is 'B - Limits,' as it aligns with the idea of boundaries or restrictions within which the nurse must operate according to medical ethics.

Correct Answer: D

Rationale: The correct answer is 'D: Capitol.' In this context, 'Capitol' is incorrect as it refers to a building where a legislative body meets. The correct term for uppercase letters is 'capital.' Choice A, 'must always,' is used correctly to emphasize the necessity of starting a sentence with a capital letter. Choice B, 'simple,' is not the incorrect word in the sentence. Choice C, 'forget,' is also used appropriately in the sentence to indicate the action of neglecting the rule.

Correct Answer: D

Rationale: 'Oneself' is the correct reflexive pronoun to use when referring to an unspecified person. In this sentence, 'oneself' is used to indicate any individual without specifying gender or number. Choices A, B, and C are incorrect as they refer to specific or known individuals, which does not fit the context of the sentence.

Correct Answer: C

Rationale: The correct answer is 'C: Threw.' In this sentence, we need the past tense form of the verb 'throw' to show the action that occurred. Therefore, 'threw' is the correct choice. 'Thorough' (choice A) means complete or exhaustive, which doesn't fit the context of the sentence. 'Through' (choice B) is a preposition or an adverb, not the correct verb form. 'Throwing' (choice D) is the present participle form and does not match the past tense needed in the sentence.

Correct Answer: D

Rationale: The term 'posterior' refers to the back of the body. Therefore, the correct answer is 'Back.' Choices A, B, and C are incorrect. 'Topmost' and 'Lowermost' do not specifically refer to the back of the body, and 'Front' is the opposite of 'Back.'
