Correct Answer: B

Rationale: The correct answer is 'B: Whole'. In this context, 'intact' means undisturbed or whole, referring to the bandage being complete and not damaged. Choice A, 'Dry', is incorrect as it does not reflect the meaning of 'intact' in this sentence. Choice C, 'Uncovered', is also incorrect as 'intact' does not imply uncovered but rather complete. Choice D, 'Secure', is not the best fit as 'intact' in this context emphasizes the undamaged or whole nature of the bandage.

Correct Answer: C

Rationale: In this context, 'vital' means absolutely necessary or essential, indicating that receiving medical attention immediately is crucial for the victim's well-being. Choice A, 'recommended,' suggests a level of advisability rather than necessity. Choice B, 'discouraged,' is the opposite of the meaning conveyed by 'vital.' Choice D, 'sufficient,' implies having enough of something, which is not the intended meaning in the given sentence.

Correct Answer: A

Rationale: The correct answer is A. In the sentence, 'be observed' should be changed to 'should be observed' for proper grammar. 'Should be observed' is the correct way to indicate the necessity of maintaining confidentiality. Choice B, 'by,' is used correctly as a preposition. Choice C, 'can be,' is also used correctly in the sentence. Choice D, 'should not,' is correctly used to indicate what the nurse ought not to do.

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: C

Rationale: 'Best' is the correct choice because it conveys the highest quality or degree in comparison, which is appropriate in this context. The sentence is discussing the opinion of coffee experts about a particular coffee blend, indicating that it is the most superior among the options. Choices A, B, and D are grammatically incorrect or redundant. 'More greater' is incorrect due to the redundant use of 'more' and 'greater.' 'Great' is a comparative form that does not fit the superlative context required. 'More greatest' is incorrect due to the unnecessary use of 'more' alongside 'greatest,' which is already a superlative form.
