Final answer:
Patients at risk for delayed wound healing include elderly patients with diabetes, patients with a history of smoking, and pregnant women without comorbidities.
Step-by-step explanation:
The nurse would place patients at risk for delayed wound healing if they have certain conditions or factors that affect wound healing. One patient at risk is an elderly patient with diabetes. Diabetes can impair blood flow and damage nerves, which can slow down wound healing. Another patient at risk is a patient with a history of smoking. Smoking can decrease the amount of oxygen in the blood and impair the immune system, both of which are important for wound healing. Additionally, a pregnant woman with no comorbidities may be at risk for delayed wound healing due to hormonal changes and increased demand on the body.
