Correct Answer: D

Rationale: A saturated abdominal dressing may indicate active bleeding or other complications that require immediate intervention. This finding suggests a potential surgical site issue that needs urgent attention to prevent further complications. Absent bowel sounds, pain level, and a slightly elevated temperature are common post-operative findings that may not necessarily require immediate intervention compared to a saturated abdominal dressing. Absent bowel sounds can be common after surgery due to anesthesia but may resolve with time. Pain and slightly elevated temperature are expected post-operative findings that can be managed with appropriate pain relief and monitoring. However, a saturated abdominal dressing indicates a potential ongoing issue at the surgical site that needs prompt assessment and intervention to prevent complications.

Correct Answer: B

Rationale: The correct action when assessing an immobile patient for deep vein thromboses (DVTs) is to measure the calf circumference of both legs. This helps in detecting swelling or changes that may indicate the presence of a DVT. Removing elastic stockings every 4 hours (Choice A) is not necessary and can disrupt circulation. Lightly rubbing the lower leg for redness and tenderness (Choice C) can potentially dislodge a clot if present. Dorsiflexing the foot while assessing for patient discomfort (Choice D) is not a specific assessment for DVT and may not provide relevant information in this context.

Correct Answer: D

Rationale: In a closed wound drainage system, it is essential to maintain the drain in a dependent position to allow for proper drainage. Gravity aids in the flow of drainage, preventing fluid backflow or pooling. Avoiding pressing the container down to create a vacuum (Choice A) is crucial as it can lead to complications in the system. Wearing sterile gloves (Choice B) is important for infection control when handling the drainage system. Resetting the container with the drainage port closed (Choice C) is incorrect as it can cause spillage and contamination of the surrounding area.

Correct Answer: A

Rationale: The correct answer is A: Wear cotton clothing to avoid static electricity. When using oxygen therapy, static electricity can pose a hazard as it increases the risk of fire. Cotton clothing helps reduce static electricity buildup. Choice B, avoiding electrical appliances, is overly restrictive and not entirely necessary. Choice C, keeping the oxygen tank away from heat sources, is important to prevent fire hazards but is not directly related to the nasal cannula. Choice D, using only a specific type of nasal cannula, is not a universal guideline and limits flexibility in care.

Correct Answer: C

Rationale: The correct answer is C: Pressure injury. Prolonged sitting can lead to pressure injuries due to continuous pressure on certain body areas, reducing blood flow and causing tissue damage. While decreased subcutaneous fat, muscle atrophy, and fecal impaction are potential concerns, pressure injuries pose the greatest immediate risk as they can lead to serious complications such as tissue necrosis and infection if not addressed promptly. Decreased subcutaneous fat and muscle atrophy may develop over time with prolonged immobility but are not as acutely dangerous as a pressure injury. Fecal impaction, while uncomfortable and potentially serious, does not pose an immediate life-threatening risk compared to the development of a pressure injury.
