Correct Answer is A
Explanation

During dressing changes, the nurse should assess for signs of infection such as increased redness, swelling, warmth, drainage, or foul odor, which could indicate an infection at the wound site.
B. Skin color changes: While changes in skin color can be indicative of various skin conditions or circulation problems, assessing for signs of infection is more pertinent during dressing changes to prevent and manage complications.
C. Decreased pain levels: Older adults may have altered pain perception due to age-related changes or comorbidities. However, assessing for signs of infection takes priority during dressing changes to ensure timely intervention if infection is present.
D. Changes in blood pressure: Changes in blood pressure may be relevant in certain clinical contexts but are not specifically related to performing dressing changes in older clients.
