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: 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. In cirrhosis, decreasing the intake of sodium-rich foods is essential to manage fluid retention and symptoms. Excessive sodium intake can worsen fluid accumulation and lead to complications such as ascites. Therefore, advising the client to decrease sodium-rich foods demonstrates an understanding of the dietary management necessary for cirrhosis. Choices A, C, and D are incorrect because increasing sodium-rich foods can exacerbate fluid retention and complications in cirrhosis, increasing potassium-rich foods is not the primary focus of dietary management in cirrhosis, and decreasing potassium-rich foods is not a key recommendation for managing cirrhosis-related dietary issues.

Correct Answer: D

Rationale: When collecting a stool specimen for ova and parasites, it is essential to place the specimen collection container in a biohazard bag. This practice ensures proper handling of potentially infectious material and prevents contamination with microorganisms. The biohazard bag should be labeled with the client's information for easy identification and proper tracking throughout the testing process. Instructing the client to defecate into a clean container is incorrect as it may introduce contaminants. Transferring the specimen to a sterile container is unnecessary and can increase the risk of contamination. Refrigerating the collected specimen is also not recommended as it may alter the sample and affect the test results.

Correct Answer: D

Rationale: When a client with major fecal incontinence reports irritation in the perianal area, the nurse's initial action should be to assess the client's perineum to gather more information. By checking the perineum, the nurse can identify the extent and nature of the irritation, allowing for appropriate interventions to be initiated. This assessment is crucial in developing a comprehensive care plan and addressing the client's immediate needs effectively. Applying the nursing process priority-setting framework helps in planning care and prioritizing nursing actions, making assessment the initial step in this scenario. Applying a fecal collection system (choice A) would be premature without assessing the perineal area first. Similarly, applying a barrier cream (choice B) or cleansing and drying the area (choice C) should follow the assessment to ensure appropriate interventions are chosen based on the assessment findings.
