Correct Answer: B

Rationale: The correct answer is B: 'Difficult to arouse.' 'Lethargic' is a medical term used to describe a state of drowsiness or lack of energy, making the patient difficult to arouse.

Choices A, C, and D describe different behaviors that are not indicative of lethargy. A patient who is pacing the halls is more likely to be agitated, while shaking uncontrollably may suggest tremors or seizures. Not responding to pain indicates a lack of reaction to painful stimuli but does not directly reflect being lethargic.

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: B

Rationale: The correct order of words to fit in the sentence structure is 'aide, aid, aid.' 'Aide' refers to a person who assists (nursing aide), while 'aid' refers to help or assistance (Band-aid and aid the nurse).
Therefore, the sequence 'aide, aid, aid' correctly completes the sentence.

Choices A, C, and D have the incorrect order of words that do not fit the sentence context.

Correct Answer: A

Rationale: The correct answer is A: 'stealthy.' 'Insidious' is often used to describe something that proceeds in a gradual, subtle, but harmful way. It is not directly or openly harmful like 'deadly,' nor does it mean 'collapsed' or 'new.'
Therefore, 'stealthy' best captures the meaning of 'insidious.'

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.
