Rationale: Step-by-step rationale: 1. A parameter is a characteristic or constant factor that defines a system. 2. It is not a constant variable (A) as it is not subject to change within a given context. 3. It is not a measurable limit (C) but rather a defining aspect of a system. 4. It is not a calculated risk (D) as it is not related to potential outcomes, but rather a fixed element. In summary, choice B is correct as a parameter is a specific, unchanging factor that characterizes a system, while the other choices do not accurately define the term.

Correct Answer: B

Rationale: Step-by-step rationale for the correct answer (B: Impoverished): 1. Indigent means lacking financial resources or in poverty. 2. The context of the question mentions the hospital accepting indigent patients, indicating a need for financial assistance. 3. Wealthy (A) is incorrect as it means having abundant financial resources. 4. Educated (C) is incorrect as it refers to having knowledge and skills, not financial status. 5. Healthy (D) is incorrect as it pertains to physical well-being, not financial status.

Correct Answer: B

Rationale: The correct answer is B: Charitable. Altruism refers to selfless concern for the well-being of others. Being charitable aligns with this definition as it involves giving to others without expecting anything in return. Choice A (Selfish) is the opposite of altruistic, focusing on self-interest. Choice C (Greedy) and D (Hateful) are also opposite in nature, as they involve a focus on personal gain or negative feelings towards others, which contradict the concept of altruism. Therefore, B is the most suitable term to describe someone who is altruistic.

Correct Answer: B

Rationale: The correct answer is B: Located outside the body. 'External' refers to something that is situated or occurring outside of the body. This term is commonly used in anatomy to distinguish between internal and external structures. Choices A, C, and D are incorrect because they do not accurately define the term 'External' as pertaining to something outside the body. Choice A refers to inside the body, Choice C refers to being exposed internally, and Choice D refers to being near the skin, but not necessarily outside the body.
