Correct Answer: B

Rationale: The correct priority action for the nurse to implement in this scenario is to determine the client's need for pain medication. Ensuring that the client is comfortable and free from pain is crucial in end-of-life care, especially for a client with a Do Not Resuscitate (DNR) order. This action prioritizes the client's comfort and dignity in their final moments. While informing the healthcare provider and beginning comfort measures are important aspects of care, pain management takes precedence as the immediate priority. Removing life-saving equipment is not appropriate at this stage as it goes against the client's wishes stated in the DNR order.

Correct Answer: B

Rationale: In pancreatitis, pain after consuming fatty foods is common due to increased pancreatic stimulation. Administering antispasmodics is the appropriate intervention as it can help reduce the pain by decreasing pancreatic enzyme secretion. Encouraging the client to eat small, low-fat meals (Choice A) is beneficial in managing pancreatitis symptoms but does not directly address the acute pain. Instructing the client to avoid eating until the pain subsides (Choice C) may lead to nutritional deficiencies and is not the best approach. Increasing high-protein foods intake (Choice D) is not recommended as it can put additional strain on the pancreas.

Correct Answer: B

Rationale: The correct answer is B: Decreased fatigue and improved energy levels. Levothyroxine is a medication used to treat hypothyroidism by providing the body with the thyroid hormone it lacks. Therefore, a positive response to the medication would manifest as decreased fatigue and improved energy levels due to the correction of the thyroid hormone imbalance. Choices A, C, and D are incorrect because improved tolerance to cold, reduced anxiety, and increased sensitivity to heat are not direct indicators of the effectiveness of levothyroxine in managing hypothyroidism.

Correct Answer: D

Rationale: The correct answer is D: "Red streaks tracking the vein." Red streaks indicate phlebitis, an inflammation of the vein that can lead to serious complications like infection or thrombophlebitis. Immediate intervention is required to prevent further damage. Choice A, cool skin at the IV insertion site, could indicate decreased circulation but is not as urgent as addressing phlebitis. Choice B, presence of fluid leaking around the IV catheter, may indicate infiltration or dislodgement of the catheter, requiring intervention but not as urgently as phlebitis. Choice C, swelling above the IV site, may suggest localized inflammation but doesn't pose an immediate threat like phlebitis does.

Correct Answer: D

Rationale: The correct answer is D: Potassium level. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Monitoring potassium levels is crucial to prevent complications such as cardiac arrhythmias. While calcium, sodium, and magnesium levels are important in various conditions and treatments, they are not the primary electrolyte affected by furosemide.
