a nurse is ordering equipment for a medical-surgical unit.
Which of the following equipment should the nurse identify as being ergonomic? (Select all that apply)

Choice A rationale
Academic pressure is a psychological stressor, not a physiological one. It involves mental or emotional strain or tension resulting from adverse or demanding circumstances, in this case, related to academic performance.
Choice B rationale
A burn injury is an example of a physiological stressor. Physiological stressors are related to physical or biological factors that strain the body’s resources. A burn injury places physical stress on the body as it tries to heal and recover.
Choice C rationale
Financial difficulties are a type of environmental stressor, not a physiological one. They involve external factors in a person’s environment that cause stress, such as financial problems or jobrelated stress.
Choice D rationale
A change in marital status is a type of psychosocial stressor, not a physiological one. It involves both psychological factors (such as emotions and behavior) and social factors (such as relationships and social interactions).

Choice A rationale
This statement is incorrect. As people age, the flexibility of the lens of the eye actually decreases, not increases. This can lead to conditions such as presbyopia, which is difficulty focusing on close objects.
Choice B rationale
As people age, their depth perception can decrease. This can make it more difficult to judge distances and can increase the risk of falls.
Choice C rationale
This statement is incorrect. As people age, the tone of the eye muscles can decrease, not increase. This can lead to conditions such as presbyopia.
Choice D rationale
This statement is incorrect. As people age, the natural lens of the eye can actually thicken, not reduce. This can lead to conditions such as cataracts.
