What is the role of the nurse in the care of a patient with a pressure ulcer?

Correct Answer: B

Rationale: The correct answer is B: Assess the wound and reposition the patient frequently. When caring for a patient with a pressure ulcer, it is crucial for the nurse to assess the wound regularly to monitor its progress and prevent complications. Additionally, repositioning the patient frequently helps to relieve pressure on the affected area, prevent further damage, and promote healing. Choice A is incorrect because while cleaning the wound is important, applying a protective dressing is not the primary role of the nurse in managing a pressure ulcer. Choice C is incorrect as applying pressure to the ulcer is harmful, and monitoring for signs of healing should not involve applying pressure. Choice D is incorrect as providing pain relief and administering antibiotics may be necessary but are not the primary interventions for managing a pressure ulcer.

Correct Answer: A

Rationale: The correct answer is A: 'Use sterile gloves and a clean dressing.' Aseptic technique in wound care requires the use of sterile gloves to prevent infection. Choice B is incorrect as the method of application does not primarily focus on maintaining asepsis. Choice C, while important for infection control, is not specific to aseptic technique in wound care. Choice D is incorrect because using a single clean glove does not ensure the level of sterility needed for aseptic wound care.

Correct Answer: A

Rationale: The correct answer is A: Clean the perineal area with soap and water. This step is essential in preventing infection and promoting hygiene. Using antiseptic wipes (choice B) is not a standard practice for perineal care; soap and water are preferred. While patting the area dry after cleaning (choice C) is important, the initial step of cleaning with soap and water is crucial. Using gloves (choice D) is a good practice to prevent the spread of infection, but it is not the initial step in providing perineal care.

Correct Answer: A

Rationale: When caring for a patient with a nasogastric (NG) tube, it is crucial to check the tube placement and assess for signs of aspiration. This ensures that the tube is correctly positioned and that the patient is not at risk of complications such as aspiration pneumonia. Choice B is incorrect as flushing the tube with water regularly is not a standard practice and may not be appropriate for all patients. Choice C is incorrect as monitoring for bowel sounds is not directly related to NG tube care, and administering medications is not the primary focus of caring for the tube itself. Choice D is incorrect because administering medications through the NG tube is a specific action that may be taken based on a healthcare provider's order, not a general care guideline for the NG tube.

Correct Answer: A

Rationale: Hypokalemia is managed by administering potassium supplements to correct the low potassium levels in the body. Monitoring the ECG is essential because low potassium levels can lead to cardiac arrhythmias. Choice B is incorrect as restricting fluid intake and providing a high-sodium diet are not appropriate for managing hypokalemia. Choice C is incorrect because hypokalemia involves low potassium levels, not sodium levels, and insulin therapy does not directly address this issue. Choice D is incorrect as calcium supplements are not indicated for hypokalemia, and monitoring for hyperkalemia is not relevant in this case.
