LPN Fundamentals Practice Questions

Correct Answer: C

Rationale: In acute renal failure, the kidneys are unable to excrete potassium efficiently, which can lead to hyperkalemia. As a result, an increased potassium level is a common finding in clients with acute renal failure. Hyperkalemia can have serious cardiac effects, making it essential for healthcare providers to monitor and manage potassium levels closely in clients with renal impairment. Choices A, B, and D are incorrect because in acute renal failure, blood urea nitrogen (BUN) and creatinine levels typically rise due to decreased renal function. Calcium levels are more likely to be decreased in acute renal failure due to impaired activation of vitamin D and subsequent decreased calcium absorption.

Correct Answer: C

Rationale: The correct answer is C because decreasing fluid intake is essential in managing fluid retention and symptoms of heart failure. Restricting fluids helps prevent excessive fluid buildup in the body, thus reducing the workload on the heart and alleviating symptoms like swelling and shortness of breath. Choices A, B, and D are incorrect. Increasing intake of foods high in sodium can exacerbate fluid retention and worsen heart failure symptoms. Increasing potassium-rich foods is beneficial for some heart conditions but not heart failure specifically. Decreasing fiber intake is not a standard recommendation for heart failure management.

Correct Answer: B

Rationale: Monitoring weight daily is crucial when taking furosemide to detect fluid retention or loss. Furosemide is a diuretic that helps the body get rid of excess water and salt through urine. Changes in weight can indicate fluid shifts, which could be a sign of inadequate response to the medication or worsening condition. Therefore, monitoring weight daily is essential to assess the effectiveness of furosemide therapy and detect any potential issues early on. Choices A, C, and D are incorrect. Avoiding foods high in potassium is more relevant for clients taking potassium-sparing diuretics, not furosemide. Taking furosemide with food is not necessary, as it can be taken with or without food. Increasing salt intake is contradictory to the purpose of furosemide, which aims to eliminate excess salt from the body.

Correct Answer: A

Rationale: The correct answer is A: 'I should avoid foods that contain lactose.' Lactose intolerance results from the inability to digest lactose, a sugar found in dairy products. Avoiding foods that contain lactose is essential in managing symptoms like bloating, diarrhea, and abdominal pain. Choice B is incorrect because increasing dairy intake would worsen symptoms. Choice C is incorrect because gluten is unrelated to lactose intolerance. Choice D is incorrect because high-fiber foods are beneficial for other conditions but do not specifically address lactose intolerance.

Correct Answer: A

Rationale: The correct answer is A. In chronic kidney disease, limiting protein intake is crucial to prevent overworking the kidneys. Excessive protein consumption can lead to the accumulation of metabolic waste products that the kidneys struggle to process, worsening kidney function. Therefore, by recognizing the need to restrict protein intake, the client demonstrates an understanding of the dietary management required for their condition. Choices B, C, and D are incorrect. Increasing intake of potassium-rich foods (Choice B) is not recommended in chronic kidney disease as it can lead to hyperkalemia. Similarly, increasing intake of phosphorus-rich foods (Choice C) is not advised because impaired kidneys struggle to excrete phosphorus, leading to elevated levels in the blood. Lastly, increasing intake of calcium-rich foods (Choice D) may not be necessary unless there is a specific deficiency or requirement, as calcium balance is often disrupted in chronic kidney disease.
