LPN Fundamentals Practice Questions

Correct Answer: B

Rationale: Measuring the tube from the client's nose to the earlobe to the xiphoid process ensures the tube is inserted to the correct depth. This measurement helps prevent complications such as tube misplacement or lung insertion. Positioning the client with the head of the bed elevated to 30� is important to facilitate easier insertion but is not the most crucial step. Lubricating the entire length of the tube with water-soluble lubricant is essential for smooth insertion but is not the most critical action. Instructing the client to cough during insertion is not necessary and may lead to unnecessary discomfort.

Correct Answer: A

Rationale: The correct answer is A. Increasing intake of foods high in vitamin D is beneficial for improving calcium absorption and managing osteoporosis. Vitamin D helps the body absorb calcium, which is essential for bone health and can aid in managing osteoporosis effectively. Choice B is incorrect because reducing calcium intake would be counterproductive for a client with osteoporosis, as calcium is crucial for bone strength. Choice C is incorrect as phosphorus, while important for bone health, does not directly impact osteoporosis management as much as vitamin D and calcium. Choice D is incorrect as potassium is not directly linked to osteoporosis management, and reducing its intake is not typically part of dietary recommendations for osteoporosis.

Correct Answer: B

Rationale: The correct answer is B: 'I should consume foods low in sodium.' This statement indicates an understanding of managing hypertension. Excessive sodium intake can lead to increased blood pressure, so reducing sodium consumption is crucial in hypertension management to prevent complications. Choices A, C, and D are incorrect. Consuming foods low in potassium is not typically recommended for hypertension management as potassium-rich foods like fruits and vegetables can be beneficial. Consuming foods high in saturated fats and cholesterol can be detrimental to cardiovascular health and should be limited in individuals with hypertension.

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: 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.
