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 initial step in caring for a client at risk for falls is to conduct a fall-risk assessment. This assessment helps the nurse gather crucial data to identify specific risks and individualized needs, guiding subsequent interventions and preventive measures. By completing a thorough assessment, the nurse can develop a targeted plan of care to mitigate fall risk and ensure the client's safety. Placing a fall-risk identification bracelet, providing nonskid footwear, or setting the bed to the lowest position may be important interventions, but these actions should be based on the findings of the fall-risk assessment, making choice A the priority.

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. Decreasing the intake of high-fat foods is essential in managing pancreatitis as high-fat foods can exacerbate symptoms and lead to complications. By reducing high-fat foods in their diet, the client demonstrates an understanding of the dietary management needed for pancreatitis. Choices A, C, and D are incorrect. Increasing high-fat foods (Choice A) is not recommended for pancreatitis as it can worsen the condition. While high-protein foods (Choice C) can be beneficial in some cases, the primary focus in pancreatitis management is on reducing fat intake. Decreasing high-protein foods (Choice D) is not a key dietary management approach for pancreatitis.

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.
