8. Diane and Elena work at a nursing home and have similar patient care assignments. At the end of every shift, Diane is tired and her back and shoulders ache while Elena feels good. What MOST LIKEY causes the difference? A. Elena must be much younger B. Elena must be much thinner C. Elena must use good body mechanics D. Diane must work much harder

## Step 1<br />The problem presents a scenario where two nurses, Diane and Elena, work at a nursing home and have similar patient care assignments. However, at the end of every shift, Diane is tired and her back and shoulders ache, while Elena feels good. The question asks us to identify the most likely cause of this difference.<br /><br />## Step 2<br />The options provided are:<br />A. Elena must be much younger<br />B. Elena must be much thinner<br />C. Elena must use good body mechanics<br />D. Diane must work much harder<br /><br />## Step 3<br />We need to consider each option and determine which one is the most likely cause of the difference in their physical state at the end of the shift.<br /><br />## Step 4<br />Option A and B suggest that Elena's age or body type could be the reason for her feeling better. However, these factors do not directly relate to the physical strain experienced by the nurses.<br /><br />## Step 5<br />Option D suggests that Diane works harder, which could lead to her feeling more tired. However, this does not explain why Elena feels better.<br /><br />## Step 6<br />Option C suggests that Elena uses good body mechanics. This is a plausible explanation because good body mechanics can help reduce the physical strain experienced by a nurse. This could explain why Elena feels better at the end of the shift.
