LPN Fundamentals Practice Questions

Correct Answer: C

Rationale: For infants and young children, the vastus lateralis muscle located over the anterior thigh is the preferred site for intramuscular injections. This site is chosen for its large muscle mass and reduced risk of injury to major nerves and blood vessels. Infants have less developed muscle structures, making the vastus lateralis a safer and more effective site for injections compared to other sites like the deltoid, ventrogluteal, or dorsogluteal. Using the correct injection site is essential to prevent complications and ensure the proper absorption of the medication.

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: A

Rationale: When assisting a client with bilateral casts on her hands with feeding, the nurse should sit at the bedside. This action is crucial to provide the client with the nurse's full attention during the feeding process. Sitting at the bedside helps avoid appearing rushed and ensures a safe and comfortable environment for the client. Choices B, C, and D are incorrect because while they may be relevant in other situations, the priority when assisting a client with bilateral casts on her hands is to ensure proper attention and a comfortable setting during feeding.

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: 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.
