LPN Fundamentals Practice Questions

Correct Answer: A

Rationale: The correct answer is A: 'I should avoid foods that contain gluten.' Celiac disease requires the avoidance of gluten-containing foods to manage symptoms and prevent complications. Gluten is found in wheat, barley, and rye. Choices B, C, and D are incorrect as they do not align with the dietary requirements for managing celiac disease. Increasing intake of foods high in gluten or lactose would be detrimental for someone with celiac disease.

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: 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: B

Rationale: The correct answer is B because reducing dairy product intake can help manage symptoms of ulcerative colitis. Dairy products can exacerbate symptoms in some individuals due to their lactose content and may need to be limited or avoided based on individual tolerance levels. Choice A is incorrect because increasing dairy products can worsen symptoms for some ulcerative colitis patients. Choice C is incorrect as while high-fiber foods are generally beneficial, they may exacerbate symptoms during a flare-up. Choice D is also incorrect as while reducing high-fat foods can be beneficial, dairy products are a more specific concern for ulcerative colitis.

Correct Answer: B

Rationale: The correct answer is B because decreasing the intake of calcium-rich foods can help manage and prevent the formation of renal calculi. Excessive calcium intake can contribute to the formation of these stones, so reducing calcium-rich foods is a key dietary modification for individuals with renal calculi. Choice A is incorrect as increasing calcium-rich foods can exacerbate the condition. Choice C is incorrect because increasing sodium-rich foods can lead to more stone formation due to increased calcium excretion. Choice D is incorrect as potassium-rich foods do not directly contribute to the formation of renal calculi.
