Correct Answer: B

Rationale: The correct answer is B: Hypokalemia. Furosemide, a loop diuretic, can cause potassium loss leading to hypokalemia. Monitoring potassium levels is crucial as low potassium can result in various complications like cardiac dysrhythmias. Choices A, C, and D are incorrect. Hypernatremia is high sodium levels, which are not typically associated with furosemide use. Hypercalcemia is elevated calcium levels and hypomagnesemia is low magnesium levels, which are not the primary electrolyte imbalances associated with furosemide.

Correct Answer: B

Rationale: The correct answer is B: Consume foods high in fiber and low in fat. Following a colon resection and a new colostomy, a high-fiber, low-fat diet is recommended to promote healing and reduce the risk of complications. Foods high in fiber help maintain bowel regularity and prevent constipation, which is crucial after this type of surgery. Choices A, C, and D are incorrect because avoiding foods high in protein, consuming foods high in vitamin C, or avoiding all raw vegetables are not the most appropriate dietary advice in this situation.

Correct Answer: D

Rationale: A WBC count of 15,000/mm3 is elevated, which may indicate infection, a common concern postoperatively. An elevated WBC count suggests the body is fighting an infection, and prompt reporting to the provider is essential for further evaluation and treatment. Serosanguineous drainage on the surgical dressing is expected in the immediate postoperative period, respiratory rate of 16/min is within the normal range, and a heart rate of 90/min is also within an acceptable range postoperatively. Therefore, these findings do not raise immediate concerns that necessitate reporting to the provider.

Correct Answer: D

Rationale: The correct answer is D: Canned soup. Canned soups are typically high in sodium, which can lead to fluid retention in clients with chronic kidney disease. Sodium restriction is crucial in managing this condition. Choice A, baked chicken, is a lean protein source that is generally recommended for individuals with kidney disease. Bananas (Choice B) are high in potassium, so clients with kidney disease may need to limit their intake depending on their individual treatment plan. Lean cuts of beef (Choice C) can be a good source of protein and iron for clients with kidney disease as long as portion sizes are controlled to manage protein intake.

Correct Answer: C

Rationale: In this scenario, the nurse should ask the provider to prescribe a different antibiotic instead of administering amoxicillin to a client with a known penicillin allergy. Choice A is incorrect because administering amoxicillin to a client with a penicillin allergy can lead to an allergic reaction. Choice B is not the best option as simply verifying the client's allergy status does not address the potential harm of giving amoxicillin. Choice D is irrelevant as checking the client's skin for rashes does not address the issue of administering a potentially harmful medication. Therefore, the most appropriate action is to request a different antibiotic from the provider to ensure the safety of the client.
