What is the best description for the word operated in this sentence? Rural communities are increasingly taking ownership of their hospitals, which may be operated by administrative medical groups.

Correct Answer: C

Rationale: In the context of the sentence provided, the word 'operated' is best described as 'managed and run.' This choice accurately reflects the idea that rural communities are taking ownership and control of their hospitals, which may be overseen and operated by administrative medical groups. The word 'operated' here implies the day-to-day management and functioning of the hospitals, making option C the most suitable description in this context. Choices A, B, and D are incorrect as they do not capture the essence of 'operated' in the context of managing and running the hospitals.

Correct Answer: D

Rationale: The abbreviation LBW stands for 'Low Birth Weight,' which specifically refers to the weight of the infant at birth. It is an important indicator of the baby's health and development, with low birth weight infants often requiring special medical attention and care. Choices A, B, and C are incorrect because LBW does not relate to genetic makeup, feeding schedule, or Babinski response; rather, it is a term used to describe infants who are born weighing less than normal, which can have implications for their health and require additional monitoring and support.

Correct Answer: D

Rationale: In this context, the word 'sanctioned' means to authorize or approve. The sentence indicates that the professor gave permission for the field trip to the chemistry lab, which aligns with the meaning of 'authorized.' Choices A, B, and C are incorrect. 'Organized' does not fit the context as the sentence is about granting approval, not arranging. 'Deterred' means to discourage, which is the opposite of what the professor did. 'Neglected' means failed to care for or pay attention to, which is unrelated to the professor approving the field trip.

Correct Answer: B

Rationale: When tubes distend, they expand or become enlarged, which typically results in stretching rather than flexing, solidifying, or collapsing. Distending tubes imply an increase in size or volume, indicating a stretching or expansion effect. Therefore, the correct answer is 'stretch.' Choice A, 'flex,' is incorrect as flexing refers to bending or curling, not expanding. Choice C, 'solidify,' is incorrect as solidifying refers to becoming solid, which is not related to the expansion of tubes. Choice D, 'collapse,' is incorrect as collapsing refers to falling in or giving way, which is the opposite effect of distending.

Correct Answer: A

Rationale: To aspirate fluid, you would typically use a syringe. A syringe is a device consisting of a tube and a plunger, which allows you to draw fluids such as blood or medication into the tube by pulling back on the plunger. This action is called aspiration, and the syringe is a common tool for this purpose in various medical procedures. Choices B, C, and D are incorrect as they are not typically used for aspiration procedures. A beaker is a glass container used for holding liquids, a test tube is used for holding or mixing small quantities of substances, and a flange is a projecting rim or edge used for strength or for attaching to another object.
