Correct Answer: B

Rationale: A nutrient is a substance that provides nourishment to the body, such as carbohydrates, proteins, fats, vitamins, and minerals. Choice A has been improved to 'A chemical compound' to be more specific. Choice A is incorrect as it is too general and does not specifically describe the role of a nutrient. Choice C is incorrect as it focuses on minerals without specifying that all minerals are nutrients. Choice D is also incorrect as it solely emphasizes vitamins, which are just one type of nutrient.

Correct Answer: B

Rationale: Anticipatory grieving occurs when an individual experiences the emotional response to the anticipated loss before it occurs. In this case, the patient who will have their left leg amputated below the knee tomorrow is facing a significant loss and is likely to be experiencing anticipatory grieving. This situation involves anticipating the physical and emotional challenges that will come with the loss of a body part, leading to emotional distress and grief before the actual amputation takes place. Choices A, C, and D do not involve an impending significant loss that would typically trigger anticipatory grieving. Giving birth, experiencing pain during physical therapy, and being discharged from the hospital, while potentially stressful situations, do not inherently involve the anticipation of a significant loss.

Correct Answer: A

Rationale: Refrain is another word for abstain, as both words mean to resist or hold oneself back from doing something. In contrast, indulge (choice B) means to allow oneself to enjoy something freely, making it the opposite of abstain. Adhere (choice C) means to stick to or follow closely, while eliminate (choice D) means to completely remove or get rid of something. Therefore, the correct answer is A, 'Refrain,' which is a synonym for 'abstain.'

Correct Answer: B

Rationale: A truculent patient is characterized by being argumentative or hostile. Therefore, the correct answer is 'B: Argumentative.' Choices A, C, and D are incorrect because a truculent patient is not passive, cooperative, or friendly.

Correct Answer: B

Rationale: The correct answer is 'She has completed the project.' The sentence uses the present perfect tense with 'has completed,' which is the correct form of the verb. Choice A is incorrect due to the subject-verb agreement error ('She' requires 'has' instead of 'have'). Choice C is incorrect as it changes the meaning by using the passive voice 'has been completed' instead of the active voice. Choice D is incorrect as 'complete' should be 'completed' to match the present perfect tense.
