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 statement to include in teaching a client with type 1 diabetes mellitus is that they can still eat sugar, but they must count it in their carbohydrate intake for the day. This is important because clients with type 1 diabetes need to manage their blood glucose levels by calculating their carbohydrate intake, including sugars. Choice B is incorrect because total avoidance of sugar is not necessary, but monitoring and including it in the carbohydrate count is essential. Choice C is incorrect as proteins and fats can also affect blood glucose levels and should be consumed in moderation. Choice D is incorrect since oral hypoglycemic agents are not used in type 1 diabetes mellitus, as insulin replacement therapy is the mainstay of treatment.

Correct Answer: A

Rationale: The correct answer is A: 'I should avoid foods that contain lactose.' Lactose intolerance results from the inability to digest lactose, a sugar found in dairy products. Avoiding foods that contain lactose is essential in managing symptoms like bloating, diarrhea, and abdominal pain. Choice B is incorrect because increasing dairy intake would worsen symptoms. Choice C is incorrect because gluten is unrelated to lactose intolerance. Choice D is incorrect because high-fiber foods are beneficial for other conditions but do not specifically address lactose intolerance.

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: Fresh fruit is naturally low in sodium and is a suitable choice for a low-sodium diet. It provides essential nutrients without adding significant amounts of sodium, making it a healthy option for individuals following a low-sodium diet. Canned soup, pickles, and soy sauce are high in sodium content and should be avoided by individuals on a low-sodium diet. Canned soups are often loaded with added salt, pickles are preserved in brine containing high sodium levels, and soy sauce is a condiment with a high sodium content.
