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

Answer and Explanation

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","B","C","D","E"]

Explanation

Choice A rationale
High glucose levels can indicate uncontrolled diabetes, which can increase the risk of surgical complications such as infection and poor wound healing.
Choice B rationale
Metformin is a medication used to treat type 2 diabetes. It can increase the risk of lactic acidosis, especially in patients undergoing procedures that involve the use of contrast dye.
Choice C rationale
A history of smoking can increase the risk of surgical complications, including poor wound healing, infection, and lung problems.
Choice D rationale
An elevated white blood cell (WBC) count can indicate an infection or inflammation in the body, which can increase the risk of surgical complications.
Choice E rationale
Type 2 diabetes mellitus can increase the risk of surgical complications, including infection, poor wound healing, and cardiovascular complications.

A. Experiencing poverty B. Being a victim of a crime C. Being part of a dysfunctional family D. Experiencing racism E. Experiencing racism

Correct Answer is B

Explanation

Choice A rationale
Experiencing poverty can indeed be a source of chronic stress due to the ongoing hardships and struggles associated with financial instability. However, it is not typically classified as an example of acute stress, which is usually associated with a specific event or situation that causes a sudden and intense reaction.
Choice B rationale
Being a victim of a crime is a prime example of an acute stressor. This is because it is a specific event that can cause immediate emotional and physiological reactions. The individual may experience intense feelings of fear, shock, or distress, and these reactions typically occur immediately after the event.
Choice C rationale
Being part of a dysfunctional family can lead to chronic stress due to ongoing family conflicts, communication problems, or other issues. While specific incidents within the family context (like a heated argument) could potentially trigger acute stress responses, the overall experience of living in a dysfunctional family is more commonly associated with chronic stress.
Choice D rationale
Experiencing racism can lead to both acute and chronic stress. Acute stress might occur in response to a specific incident of racial discrimination, while chronic stress could result from living in a society where racism is pervasive. However, without a specific incident mentioned, it is less likely to be considered an example of acute stress compared to being a victim of a crime.
