Correct Answer: A

Rationale: The correct answer is A. "Do to" should be corrected to "due to" in this context. The sentence should read, "The client's hospital stay was prolonged, due to a superinfection." The phrase "due to" is the appropriate choice to indicate the cause of the prolonged hospital stay. Choices B, C, and D are all used correctly in the sentence and do not contain any errors.

Correct Answer: B

Rationale: The correct answer is 'B: Abrupt.' In this context, 'precipitous' is used to describe a change that occurs suddenly or abruptly. Choice A ('Difficult') is incorrect as it does not capture the sudden nature of the change. Choice C ('Gentle') is incorrect as it conveys the opposite meaning of 'precipitous.' Choice D ('Unanticipated') is incorrect as it focuses on the element of surprise rather than the suddenness of the change.

Correct Answer: D

Rationale: The correct answer is D: 'offensive.' Repugnant means offensive or disgusting. In this context, 'destructive,' 'selective,' and 'collective' do not accurately capture the meaning of 'repugnant,' making them incorrect choices. 'Offensive' is the most appropriate term to describe something that is repugnant.

Correct Answer: C

Rationale: The correct answer is 'Were raised.' This phrase is the correct passive form, indicating the action of lifting the glasses during the toast. Choices A, B, and D are incorrect because 'were risen' is not grammatically correct, 'were rose' is not the appropriate verb form, and 'arose' does not convey the action of lifting the glasses as required in the sentence.

Correct Answer: A

Rationale: 'Occluded' means blocked or obstructed, making 'Obstructed' the correct answer. In the context of a patient having an occluded artery, it implies that the artery is blocked. The other options, 'Open,' 'Broken,' and 'Cloudy,' do not accurately describe a blocked artery.
