Answer to Question 1

A
Feedback:
A proxy variable is a measurable variable that stands in place of the variable of interest. The variable of interest is sometimes impractical to measure because of technical difficulty, excessive expense, ambiguity, abstraction, or multiple facets. In the case of patient outcome, the concept has too many facets to allow a practical enquiry. Length of hospital stay is often chosen when rapidity of response to the pre-morbid state is the study's principal focus. Eligibility for Medicare, staffing ratios, and falls risk are not outcomes: they are, according to Donabedian's framework, structures of care

Answer to Question 2

B

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
