What is the term for the lower surface of a structure?

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: 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: 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: 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: C

Rationale: The term 'etiology' refers to the cause or origins of a disease. In this context, the question is asking for the underlying reason or cause of the flu epidemic of 1918. Therefore, the correct answer is C. 'Etiology.' Choice A, 'Pathology,' is incorrect as it refers to the study of diseases rather than the cause itself. Choice B, 'Transmission,' is incorrect as it relates to how a disease spreads rather than its cause. Choice D, 'Mortality rate,' is incorrect as it refers to the number of deaths caused by a disease rather than the cause of the disease itself.
