A nurse is analyzing cues during the evaluation of a client's altered tissue integrity.
Which of the following findings should prompt differential diagnosis between cellulitis and dermatitis?
Flaky skin.
Presence of pustules.
Sunburn appearance.
Dry patches.
The Correct Answer is B
Choice A rationale
Flaky skin, or desquamation, is a non-specific finding that can be seen in various conditions, including chronic dermatitis or simple xerosis. It represents the shedding of the outermost layer of the epidermis and does not effectively differentiate between the deep bacterial infection of cellulitis and the more superficial inflammatory reaction of dermatitis. While it indicates a disturbance in skin barrier function, it lacks the diagnostic specificity required to confirm the presence of an acute infectious process.
Choice B rationale
The presence of pustules is a significant clinical cue that often points toward an infectious etiology, such as folliculitis or localized cellulitis, rather than simple contact dermatitis. Pustules contain purulent exudate consisting of white blood cells and cellular debris, signaling a primary immune response to bacteria like Staphylococcus aureus. While some forms of dermatitis can become secondarily infected, finding pustules early in the assessment prompts the clinician to investigate bacterial invasion more thoroughly through cultures.
Choice C rationale
A sunburn appearance, characterized by diffuse erythema, can be seen in both cellulitis and various types of dermatitis, such as actinic or contact dermatitis. Because both conditions involve vasodilation and increased blood flow to the skin, redness alone is not a reliable differentiator. Cellulitis typically presents with more distinct warmth and spreading borders, but the visual similarity to a sunburn makes it a poor diagnostic marker for distinguishing between the two inflammatory states.
Choice D rationale
Dry patches are common in many dermatological conditions, particularly atopic dermatitis or eczema, where the skin barrier is chronically compromised. While they indicate altered tissue integrity, they do not specifically suggest the deep tissue inflammation and infection characteristic of cellulitis. Cellulitis is more often associated with taut, shiny, and swollen skin rather than dry, scaly patches. Therefore, observing dry patches is more helpful for identifying chronic skin conditions rather than diagnosing an acute infection.

Related Questions
Correct Answer is A
Explanation
Choice A rationale
This response demonstrates therapeutic communication by acknowledging the client's autonomy and using an open-ended question to explore their feelings. In geriatric care, psychological adaptation to limb loss is complex. By asking what the client would like to do, the nurse validates their right to self-determination while gathering data on specific fears or barriers. This approach fosters a collaborative relationship, which is essential for eventual rehabilitation success and emotional well-being.
Choice B rationale
Telling the client that the provider will be called shifts the responsibility away from the nurse-client relationship and ignores the client's expressed concern. While the provider must be informed of a refusal of treatment, the nurse's immediate role is to explore the client's emotional state. This response is dismissive and fails to address the underlying anxiety or hopelessness the client is feeling regarding their ability to adapt to a new prosthetic limb.
Choice C rationale
This response uses a generalization and provides false reassurance, which can be non-therapeutic. While many older adults do adapt well to prostheses, telling a specific client this invalidates their personal struggle and individual feelings of inadequacy. It minimizes the client's unique experience and may make them feel misunderstood. Effective nursing requires focusing on the individual's specific concerns rather than comparing them to a broad demographic of other patients.
Choice D rationale
Stating that learning is mandatory is an authoritative and confrontational approach that violates the client's right to refuse treatment. Coercion creates a power struggle and can increase the client's resistance to rehabilitation. It fails to address the psychological barriers to learning and ignores the fact that the client is already back in a nursing home setting. Education should be based on readiness and mutual goals rather than mandates and threats.
Correct Answer is []
Explanation
🎯 Most Likely Condition
- Surgical site infection Rationale: The client has localized redness, swelling, tenderness, warmth, and a rising temperature (from 37.8°C to 38.1°C). These are hallmark signs of infection rather than normal post-op healing.
🩺 Actions the Nurse Should Take
- Clean and dress the wound Rationale: Maintains sterility, prevents further contamination, and addresses the partially detached dressing.
- Administer antibiotics as ordered Rationale: Treats the underlying infection directly, per provider orders.
📊 Parameters to Monitor
- Vital signs Rationale: Fever, tachycardia, and changes in blood pressure or respiratory rate can indicate systemic spread of infection.
- Incision appearance Rationale: Monitoring redness, swelling, warmth, and drainage helps track local infection progression or resolution.
