A nurse is instructing a newly licensed nurse about age-related changes to vision in older adult patients.
Which of the following should the nurse include as an example of an expected age-related change?
Increased flexibility of the lens
Decreased depth perception
Increased tone of eye muscles
Reduced thickness of the natural lens
The Correct Answer is B
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.

Correct Answer is ["A","C"]
Explanation
Choice A rationale
Mottling of the skin, especially in the lower extremities, is a common sign of impending death. This is due to decreased blood flow and can be a sign that the body is starting to shut down.
Choice B rationale
This statement is incorrect. As a person nears death, their blood pressure typically decreases, not increases.
Choice C rationale
Cheyne-Stokes breathing, which is characterized by a pattern of increasing and decreasing respiration with periods of apnea, is a common symptom in the final stages of life.
Choice D rationale
This statement is incorrect. As a person nears death, their skin may become cool to the touch and may appear pale or mottled.
Choice E rationale
Regular respiration is not typically a sign of impending death. In fact, changes in breathing patterns, such as Cheyne-Stokes breathing, are more common.
Correct Answer is B
Explanation
Choice A rationale
While prothrombin level is an important test in evaluating blood clotting disorders, it is not typically used in the initial diagnostic evaluations for a cerebrovascular accident (CVA) or stroke.
Choice B rationale
Brain CT or MRI scans are commonly used in the initial diagnostic evaluations for a CVA. These imaging tests can show bleeding in the brain, an ischemic stroke, a tumor, or other conditions.
Choice C rationale
A chest x-ray is not typically used in the initial diagnostic evaluations for a CVA. It is more commonly used to diagnose conditions affecting the lungs and heart.
Choice D rationale
A lumbar puncture, or spinal tap, may be used in some cases to help diagnose a CVA, but it is not typically part of the initial diagnostic evaluations.
