Correct Answer: C

Rationale: The correct answer is C: Raisins. Raisins are a good source of iron, which can help prevent or address iron deficiency anemia. Yogurt (Choice A) and cheddar cheese (Choice D) are not significant sources of iron. While apples (Choice B) are a healthy fruit, they do not contain as much iron as raisins.

Correct Answer: B

Rationale: A positive Kernig's sign is identified when a client is unable to extend their leg completely without pain after hip flexion. This finding indicates meningeal irritation. Choices A, C, and D do not describe Kernig's sign. Choice A describes a normal plantar reflex, choice C refers to coordination issues, and choice D describes neck pain and stiffness, which are not specific to Kernig's sign.

Correct Answer: B

Rationale: The correct answer is B: "Increase intake of high-potassium foods." Furosemide is a loop diuretic that can lead to hypokalemia, a condition characterized by low potassium levels. To prevent this adverse effect, the client should increase their intake of high-potassium foods. Choice A is incorrect because furosemide typically leads to decreased blood pressure, not increased. Choice C is incorrect because furosemide is used to reduce swelling, not increase it. Choice D is incorrect because the second dose of furosemide should be taken in the morning to prevent nocturia.

Correct Answer: B

Rationale: The correct answer is B. The circumference of the upper arm above the insertion site of the PICC should be measured at the time of insertion and then again during assessments. An increase in circumference could indicate deep vein thrombosis, which could be life-threatening. Choice A is not a concern as changing the dressing 7 days ago is within the recommended timeframe. Choice C is not alarming as the catheter not being used for 8 hours does not necessarily indicate a problem. Choice D indicates proper catheter care by flushing it with sterile saline after medication use, so it does not require provider notification.

Correct Answer: D

Rationale: The priority action is to verify the prescription with the provider. Verifying the prescription ensures patient safety by preventing fluid volume overload and dysrhythmias, which can result from infusing potassium too rapidly. Teaching the client about IV extravasation, evaluating IV patency, and consulting with the pharmacist are important but should come after verifying the prescription to ensure the ordered treatment is appropriate and safe for the client's condition.
