Final answer:
Bertha is neither recumbent, supine, nor prone; she is sitting upright. Therefore, the correct answer to the position Bertha is in while being fed chicken broth is 'd. None of the above'.
Step-by-step explanation:
The question pertains to body positions and which term best describes the position in which Bertha is sitting while being fed chicken broth. In this scenario, Bertha was sitting upright, which means she was in a vertical position with her back straight, similar to how one would sit on a chair.
Considering the information provided and the options available:
Ergonomically is a term related to the efficient and comfortable design of workspaces and products.
Recumbent refers to a lying down position, which is not applicable since Bertha is sitting upright.
Supine means lying on one's back, which is also not applicable as Bertha is sitting.
Prone is when a person is lying face down, which again, does not describe sitting upright.
None of the above is the correct option since the other choices do not accurately describe Bertha's position.
Therefore, the correct answer is d. None of the above, as Bertha is neither recumbent, supine, nor prone while being fed chicken broth; she is in an upright seated position.
