A client has a stage 3 pressure ulcer on the left trochanter with moderate serosanguineous drainage. The wound is $4 cm in length, $3 cm in width, and $2 cm in depth. The wound bed is $80% granulation tissue and $20% slough. Which type of dressing should the nurse use for this wound?

Correct Answer: C

Rationale: Alginate is the correct dressing for a stage 3 pressure ulcer with moderate serosanguineous drainage, depth, and mixed tissue. Derived from seaweed, alginate absorbs moderate to heavy exudate (up to 20 times its weight), forming a gel that maintains moisture, supports autolytic debridement of the 20% slough, and fills the 2 cm depth, promoting healing. Hydrocolloid suits minimal drainage, risking maceration in deeper, exudative wounds. Hydrogel hydrates dry wounds but can't handle moderate drainage, potentially leaking. Transparent film is non-absorbent, unfit for exudate or depth, and better for superficial wounds. Alginate's absorbency and adaptability make it ideal for this wound's characteristics, balancing moisture and clearing debris effectively.

Correct Answer: D

Rationale: A and C,' as unintentional wounds are characterized by being accidental and often having clean edges, depending on the cause. 'Accidental' fits because unintentional wounds result from unplanned events like falls or cuts, not deliberate actions like surgery. 'Clean edges' applies to wounds from sharp objects (e.g., a knife slice), common in accidents, though not universal jagged edges can occur too. 'High risk for infection' isn't exclusive to unintentional wounds; it depends on contamination, not intent, and intentional wounds (e.g., surgical) can also get infected if mishandled. Combining A and C captures key traits without overgeneralizing infection risk. In nursing, recognizing these features aids assessment accidental wounds may need tetanus prophylaxis, and clean edges suggest primary closure potential. 'All of the above' (E) overstates infection specificity, making D the precise choice per wound classification principles.

Correct Answer: D

Rationale: Obtain clean towels,' as it's a mistake in managing dehiscence a surgical wound reopening. Proper protocol requires sterile materials (e.g., saline-moistened sterile dressings) to cover the wound, preventing contamination, not just clean towels, which may harbor bacteria. 'Notify the physician' is correct urgent reporting is essential. 'All of the above have mistakes' is wrong, as A is valid. 'None of the above have mistakes' overlooks D's error. In nursing, sterility is critical in dehiscence to avoid infection or evisceration; clean towels fail this standard. The document lists 'Moisten towels with sterile 0.9% sodium chloride' separately, implying D's non-sterile intent is the flaw, making it the mistaken step.

Correct Answer: C

Rationale: All of the above,' as 'decubitus ulcer' and 'bedsore' are both synonyms for 'pressure ulcer.' All describe localized skin and tissue damage from prolonged pressure, often over bony prominences, common in bedridden patients. 'Decubitus ulcer' derives from Latin for 'lying down,' emphasizing position-related etiology. 'Bedsore' is a colloquial term for the same condition, highlighting its association with immobility. 'All of the above' captures their interchangeability in medical and lay contexts. 'None of the above' is incorrect terminology aligns across nursing texts. In practice, recognizing these terms ensures clear communication e.g., documenting 'decubitus ulcer' or educating families about 'bedsores.' C's inclusivity matches the question's intent, reflecting standard wound care vocabulary.
