A client who was discharged 3 days ago after an exploratory laparoscopic biopsy is admitted to the hospital with a warm, tender, reddened, and swollen left lower leg. The nurse is preparing to initiate heparin therapy. Which additional intervention should the nurse include in this client's plan of care?

Rationale for correct choices:

• Cellulitis: The client presents with redness, warmth, swelling, and pain in the left lower leg, along with a small preceding cut. These findings are characteristic of cellulitis, a bacterial infection of the dermis and subcutaneous tissue, often following a breach in the skin barrier.

• Break in skin: The small cut noted above the lateral ankle provides an entry point for bacteria, explaining the localized infection. A break in skin is a common precursor to cellulitis, particularly in clients with diabetes or vascular compromise.

• Left lower leg erythema: Erythema indicates inflammation and infection, which are hallmark signs of cellulitis. The presence of erythema, along with swelling and warmth, supports the clinical diagnosis of a bacterial skin infection.

Rationale for incorrect choices:

• Left lower leg erythema (as a diagnosis option): Erythema alone describes a symptom rather than a medical diagnosis. While present, it does not capture the underlying bacterial infection requiring treatment.

• Break in skin (as a diagnosis option): A break in the skin is a risk factor or contributing event, not a formal diagnosis. It explains how infection occurred but does not replace the clinical diagnosis of cellulitis.

• Cool, pale left leg: This finding is more indicative of arterial insufficiency or ischemia rather than infection. The client’s affected leg is warm and erythematous, which contrasts with cool, pale tissue.

• Intact skin: Intact skin would not allow bacterial entry and does not explain the localized infection. The client has a visible small cut that preceded the erythema.

• Dry scaly skin: While common in peripheral vascular disease or chronic dermatologic conditions, dry scaly skin does not explain the acute signs of infection seen in this client.

A. Argumentativeness and use of profanity: These behaviors may indicate escalating agitation and a risk for violence. Monitoring for verbal aggression is essential because it can quickly progress to physical aggression, making safety the priority concern.

B. Periodic sighing and shaking the head: These are signs of frustration or discouragement but are less concerning than overt verbal aggression. They do not immediately signal a risk of harm to others.

C. Decreased activity level and change in affect: A decline in activity or affect may suggest depression or withdrawal but does not indicate an acute risk of violent escalation like pacing and scowling combined with verbal aggression.

D. Repeated requests for attention from the nurse: Frequent requests may reflect anxiety or dependency but do not typically indicate imminent aggression. While they should be addressed, they are not the most critical behaviors to monitor in this scenario.
