A nurse is caring for a client with a chronic wound. Which of the following is a systemic cause of chronic wounds?

A. Smoking causes you to cough frequently, and the wound might get infected by sputum.

While smoking can indeed contribute to respiratory issues like coughing, linking this directly to wound infection by sputum is not the most accurate explanation of how smoking affects wound healing. The primary concern with smoking and wound healing lies in its effects on circulation and tissue oxygenation rather than the risk of infection due to coughing.

B. Nicotine causes vasoconstriction, so your wound might not get enough blood flow to heal.

This is the best response among the options provided. Nicotine, a major component of cigarette smoke, is known to constrict blood vessels (vasoconstriction). This constriction reduces blood flow to the wound site, leading to decreased delivery of oxygen and nutrients necessary for proper wound healing. It addresses the direct physiological impact of smoking on wound healing and provides a clear explanation for the client.

C. Nicotine causes tar to build up in the wound, and it will impair healing.

While nicotine and other components of tobacco smoke can have detrimental effects on healing, particularly through vasoconstriction, the explanation about tar building up in the wound is not entirely accurate. Tar is more associated with lung damage from smoking rather than direct buildup in external wounds. Therefore, this response is less specific and may confuse the client about the actual mechanism of how smoking affects wound healing.

D. Smoking is bad, and you should stop right away.

While this response emphasizes the importance of smoking cessation, it lacks specificity in explaining how smoking impacts wound healing. Providing specific information about vasoconstriction due to nicotine, as mentioned in option B, would be more helpful in helping the client understand the direct effects of smoking on their chronic wound and why cessation is crucial.

A. “Call your surgeon if you have any questions at home.”

This instruction is important as it encourages the patient to seek help and clarification if they have any concerns or questions about their postoperative care at home. However, while communication with the surgeon is essential, it is not as immediately critical as ensuring proper hand hygiene when dealing with wound care and drain management.

B. ”Eat a diet high in protein, iron, zinc, and vitamin C.”

Nutritional advice is crucial for postoperative recovery, as a balanced diet high in protein, iron, zinc, and vitamin C can promote wound healing and overall recovery. However, while important for long-term recovery and healing, dietary recommendations do not directly address the immediate risk of infection or complications associated with wound care and drain management.

C. “Wash your hands before touching the drain or dressing."

This instruction is the most important in this context because proper hand hygiene is crucial for preventing infections during wound care and drain management. Clean hands significantly reduce the risk of introducing harmful bacteria or contaminants to the surgical site, which can lead to infections and other complications. Ensuring that the patient washes their hands before touching the drain or dressing is a fundamental measure for promoting wound healing and preventing postoperative complications.

D. “Be sure you keep all your postoperative appointments.”

Keeping postoperative appointments is important for ongoing assessment, monitoring, and follow-up care. However, while essential for overall recovery and management of postoperative issues, it is not as immediate or directly related to the patient's ability to manage their dressing and drain at home.
