Rationale: The correct nursing intervention for a patient with a pressure ulcer is to clean the wound and apply a hydrocolloid dressing. This promotes healing by creating a moist environment conducive to the wound healing process. Choice B is incorrect because while nutrition is important for wound healing, a high-protein diet alone is not a specific intervention for a pressure ulcer. Choice C is incorrect as antibiotics are only used if there is an infection present. Choice D is also incorrect as a low-sodium diet and monitoring for fluid retention are more related to conditions like heart failure or kidney disease, not specifically pressure ulcer care.

Correct Answer: B

Choice A is incorrect because monitoring blood sugar levels weekly may not provide timely information for managing diabetes. Choice C is incorrect as medications for diabetes should be taken as prescribed, not only when feeling unwell. Choice D is incorrect as blood sugar levels should be monitored at various times throughout the day, not just in the morning, to get a complete picture of the patient's condition.

Correct Answer: D

Rationale: The key considerations for managing a patient with COPD include oxygen therapy, which is essential to maintain adequate oxygen saturation levels. While bronchodilators are commonly used to manage COPD symptoms, they are not the primary consideration. Smoking cessation is crucial in preventing further damage but is not a direct management consideration. Pulmonary rehabilitation is beneficial for improving exercise capacity and quality of life but is not as crucial as ensuring adequate oxygen therapy.

Rationale: During a seizure, the most appropriate action for a healthcare provider is to protect the patient's head. This helps prevent injury, especially considering the involuntary movements and potential thrashing associated with seizures. Restraint should be avoided as it can lead to further injury or distress for the patient. Inserting an airway is not recommended during an active seizure as the patient's airway may not be obstructed, and it could pose a risk of injury. Giving the patient water during a seizure is also not advisable as there is a risk of aspiration. Therefore, the priority is to ensure the patient's safety by protecting their head.
