LPN Fundamentals Practice Questions

Correct Answer: B

Rationale: The correct answer is B. In hyperlipidemia management, decreasing the intake of foods high in cholesterol is crucial to improve lipid levels and reduce the risk of cardiovascular diseases. Choices A and C are incorrect as increasing intake of saturated fats or trans fats can raise cholesterol levels, worsening the condition. Choice D is incorrect because decreasing intake of foods high in fiber is not recommended as fiber-rich foods are beneficial for heart health, which is important in managing hyperlipidemia.

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.

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: A

Rationale: Elevating the head of the bed to 30� is the correct action to take when a client is receiving continuous enteral feedings through a nasogastric tube. This position helps prevent aspiration of the enteral feedings into the lungs, reducing the risk of aspiration pneumonia. Additionally, elevating the head of the bed promotes proper digestion and absorption of the feedings by utilizing gravity to facilitate movement into the stomach and through the gastrointestinal tract. Flushing the tube with water every 2 hours (Choice B) is not necessary for continuous feedings and may disrupt the feeding schedule. Replacing the feeding bag and tubing every 72 hours (Choice C) is not the standard recommendation unless there are specific concerns or complications. Checking the client's gastric residual every 8 hours (Choice D) is important but not the immediate action needed to prevent aspiration during enteral feedings.

Correct Answer: A

Rationale: The correct answer is A: Avoid beverages containing caffeine. Caffeine is a stimulant that can interfere with sleep, making it difficult for the client to fall asleep at night. Taking sleep medication regularly (choice B) may not address the root cause of the sleep difficulty and can lead to dependency. Watching television in bed (choice C) can actually stimulate the brain and hinder relaxation before sleep. Advising the client to take several naps during the day (choice D) can disrupt the sleep-wake cycle further. Therefore, recommending the avoidance of caffeine-containing beverages is the most appropriate intervention to help the client improve their ability to sleep at night and function better during the day.
