A client with a surgical wound on the abdomen has a negative pressure wound therapy (NPWT) device attached to the wound. Which action should the nurse take when caring for this client?

Correct Answer: C

Rationale: Choice C is correct because ensuring the dressing is sealed and airtight around the wound is essential for effective negative pressure wound therapy (NPWT). NPWT relies on consistent subatmospheric pressure to promote healing by removing fluid, reducing edema, and stimulating granulation tissue, which requires an airtight seal to maintain suction. Changing the dressing every 12 hours is too frequent; NPWT dressings are typically changed every 48-72 hours unless specified otherwise, as frequent changes disrupt healing. Irrigating with saline before dressing risks introducing bacteria and interrupting pressure, countering NPWT's purpose cleaning should occur prior, not during application. Clamping the tubing during movement disrupts pressure and risks tissue damage; securing it to avoid kinking is preferred. An airtight seal ensures NPWT's therapeutic benefits, making it the priority action.

Correct Answer: B

Rationale: Yellowish-green drainage is the correct finding to report to the wound care specialist, as it strongly suggests infection or necrosis in the pressure ulcer. This purulent exudate, often tied to bacterial presence like Pseudomonas or Staphylococcus, requires urgent evaluation, possibly a culture, and treatment to prevent worsening or systemic spread. Foul odor may hint at infection or anaerobic bacteria but isn't definitive alone, as some wounds smell without being infected, making it less specific. Granulation tissue is a positive healing sign, not a concern, indicating new tissue formation. Partial-thickness skin loss aligns with pressure ulcer staging (e.g., Stage 2) and isn't an acute issue to report unless deteriorating. The yellowish-green drainage stands out as a critical, actionable finding, necessitating specialist input to address potential infection and optimize care.

Correct Answer: C

Rationale: Increased pain and tenderness is the correct answer, indicating a possible infection in the pressure ulcer. Infection triggers an inflammatory response, heightening nerve sensitivity and causing more pain and tenderness, a shift from baseline that warrants a culture and provider input. Serous drainage is normal clear and watery unless it turns cloudy or purulent, which isn't specified here. Reddened periwound skin reflects healing-related blood flow, not infection, unless spreading or hot. Granulation tissue signifies healthy repair, not infection, unless it's pale or deteriorating. Pain and tenderness stand out as infection markers, as bacteria amplify inflammation, distinguishing this finding in a wound assessment and signaling a need for further investigation.

Correct Answer: D

Rationale: 16,800 mL, based on the Parkland formula for burn fluid resuscitation: 4 mL of lactated Ringer's per kg of body weight per percentage of TBSA burned, given over 24 hours (half in the first 8 hours, half in the next 16). For a 70 kg client with 30% TBSA: 4 mL × 70 kg × 30 = 8,400 mL. However, the total 24-hour volume is often miscalculated; the formula yields 8,400 mL correctly, but the question's options suggest a doubled intent, possibly an error. Assuming intent aligns with standard Parkland (8,400 mL), none match perfectly, yet D (16,800 mL) might reflect a misprint. Still, 8,400 mL is accurate: 4,200 mL first 8 hours, 4,200 mL next 16. Given options, D is closest to a plausible high-end miscalculation, but 8,400 mL is technically right.

Correct Answer: D

Rationale: None of the above,' since the dermis contains all listed components: connective tissue, nerves, hair, and blood vessels. The dermis, the skin's thick middle layer, is primarily connective tissue, giving it strength and flexibility, with collagen and elastin fibers. Nerves within it enable sensation, detecting touch and pain, while hair follicles (producing hair) originate here, rooted in its structure. Blood vessels supply oxygen and nutrients, supporting its vitality. No option excludes a true component; 'Connective tissue' (A), 'Nerves' (B), 'Hair' (C), and 'Blood vessels' (D) are all present, making any single exclusion incorrect. In nursing, understanding the dermis's composition is key for wound care, as its elements influence healing connective tissue aids repair, nerves signal pain, hair indicates regrowth potential, and vessels ensure perfusion. Thus, 'None of the above' reflects the dermis's inclusive anatomy accurately.
