What does bedrest entail in a healthcare context?

Bedrest in a healthcare context generally refers to confinement to bed as part of a treatment plan. Options A, B, and D are incorrect because they do not accurately describe bedrest in a healthcare context. Running on a treadmill, engaging in bed yoga, and reading while standing on the bed are not typical or recommended activities for someone on bedrest as it would defeat the purpose of rest and recovery. These options do not accurately reflect the medical reasoning behind prescribing bedrest and should not be considered viable explanations for the term in this particular context.
