LPN Fundamentals Practice Questions

Correct Answer: B

Rationale: The correct answer is B. Decreasing the intake of purine-rich foods is essential in managing gout as purines break down into uric acid, contributing to gout symptoms. Increasing purine-rich foods would exacerbate the condition by increasing uric acid levels. Therefore, choice A is incorrect. Choices C and D are also incorrect as increasing sodium-rich foods (choice C) is not recommended for gout management, and decreasing potassium-rich foods (choice D) is unrelated to gout.

Correct Answer: C

Rationale: The correct answer is C: Lentils. Incomplete proteins lack one or more essential amino acids required for protein synthesis in the body. Examples of incomplete proteins include lentils, vegetables, grains, nuts, and seeds. Lentils, a plant-based protein source, are considered incomplete as they do not contain all essential amino acids in sufficient amounts. Choices A, B, and D are incorrect as eggs, soybeans, and yogurt are examples of complete proteins, containing all essential amino acids in the right proportions for the body's needs.

Correct Answer: B

Rationale: Correct! Hyperkalemia is a condition characterized by high levels of potassium in the blood. To manage hyperkalemia, it is essential to decrease the intake of potassium-rich foods since excess potassium can worsen the condition. By understanding the need to decrease potassium-rich foods, the client shows comprehension of the dietary management required for hyperkalemia. Choice A is incorrect because increasing potassium-rich foods would exacerbate hyperkalemia. Choice C is incorrect since increasing sodium-rich foods is unrelated to managing hyperkalemia and could potentially lead to other health issues. Choice D is incorrect as decreasing sodium-rich foods is not the primary focus when managing hyperkalemia.

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: When following a low-fat diet, it is essential to choose foods that are low in fat. Chicken breast is a lean protein source that is low in fat, making it a suitable option for a low-fat diet. Bacon, whole milk, and cheese are higher in fat content and should be avoided or limited in a low-fat diet. Bacon is high in saturated fat, whole milk contains significant amounts of fat, including saturated fat, and cheese is also high in fat. Therefore, these options are not ideal for a low-fat diet.
