What action describes what a cat, who is clearly scared of a Rottweiler, will do when the dog enters the room?

Correct Answer: A

Rationale: When a cat cowers, it means the cat is crouching down or trying to make itself look smaller in fear or apprehension of something, in this case, the Rottweiler. Hence, the word 'cower' accurately describes what the cat would do when faced with a Rottweiler entering the room. The other choices are incorrect: 'Engender' means to cause or give rise to, 'Enhance' means to improve or increase the quality or value of something, and 'Replicate' means to duplicate or reproduce something.

Correct Answer: C

Rationale: The word 'staggered' is associated with unsteadiness or imbalance in movement. Stumbling is the most suitable synonym among the given choices to convey this meaning. 'Fell,' 'fumbled,' and 'pirouetted' do not accurately capture the idea of unsteadiness or imbalance conveyed by the word 'staggered.' 'Fell' generally means coming down from a standing position, 'fumbled' implies clumsiness or mishandling, and 'pirouetted' refers to a specific graceful ballet move, none of which align with the meaning of 'staggered.'

Correct Answer: D

Rationale: The term for the lower surface of a structure is 'ventral.' 'Ventral' is used in anatomy to describe the front or lower surface of an organism or structure. In this context, 'inferior' (choice A) is not the correct term as it generally refers to something being below or lower in position but not specifically the lower surface of a structure. 'Transverse' (choice B) refers to a crosswise direction, not the lower surface. 'Dorsal' (choice C) is the term used for the upper or back surface of an organism or structure, opposite to the ventral surface.

Correct Answer: A

Rationale: The word 'labile' is used to describe something that is constantly changing or easily altered. Therefore, the best synonym for 'labile' is 'extremely changing.' Choice B, 'suicidal,' is incorrect as it does not relate to the meaning of 'labile.' Choice C, 'rapidly changing,' is close but not as precise as 'extremely changing.' Choice D, 'with a high fever,' is completely unrelated to the meaning of 'labile.'

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: D

Rationale: The correct answer is D: 'On the side.' Lateral means situated on the side or away from the midline. Choices A, B, and C are incorrect because lateral specifically refers to a position that is situated away from the midline, not near it, at the top of the body, or on the side.

Correct Answer: B

Rationale: The correct answer is B: 'Obvious or easily observed.' Overt means something that is not hidden or concealed but rather openly displayed or easily noticed. Choice A, 'Hidden,' is the opposite of overt. Choice C, 'Barely noticeable,' implies something not overt but rather subtle. Choice D, 'Misleading,' is unrelated to the definition of overt.

Correct Answer: A

Rationale: The correct answer is A: 'Thick and sticky.' Viscous describes a substance that is thick and sticky, resisting flow easily. Choices B, C, and D are incorrect. 'Slimy' implies a slippery, gooey texture; 'Watery' describes a substance with a thin, fluid consistency; and 'Dry' indicates the absence of moisture.
