Rationale: The correct answer is C: Experimental. The word "experimental" implies trying new methods or approaches before resorting to a standard procedure. In this context, the doctor wants to explore different options before considering a risky or invasive procedure. A: Internal - This choice does not fit the context of trying alternative methods before a procedure. It refers to something inside the body, not the nature of the procedure itself. B: Painful - This choice focuses on the potential discomfort of the procedure, which is not the main point of the sentence. The doctor is emphasizing trying other approaches first. D: Expensive - This choice does not relate to the idea of trying different methods before a procedure. The cost of the procedure is not the primary concern in this sentence.

Correct Answer: B

Rationale: The correct answer is B: Maintenance of body fluid. Hydration refers to the process of maintaining adequate levels of body fluid for proper bodily functions. This includes water intake, absorption, and distribution throughout the body. Choice A is incorrect because dehydration is the opposite of hydration. Choice C is incorrect as it refers to the loss, not maintenance, of water. Choice D is incorrect as draining fluids does not encompass the comprehensive concept of hydration. Maintaining body fluid balance is crucial for various physiological processes, making option B the correct choice.

Correct Answer: B

Rationale: The correct answer is B: To draw together. Constrict means to tighten or squeeze together, making something narrower or tighter.

Therefore, the correct answer is B because it best aligns with the definition of constrict.

Gagging is a common response to unpleasant odors as the body tries to expel the offending stimulus. Enjoy (B) is incorrect as it implies a positive experience, which is not the case here.

Attach (D) is also incorrect as it does not fit the context of a bad smell causing a physical reaction like gagging.

Choices A, C, and D are all essential and ethical practices in healthcare. The Heimlich maneuver is used to save choking victims, assessment is crucial for diagnosing and treating patients, and palliative care focuses on improving quality of life for terminally ill patients.
