LPN Fundamentals Practice Questions

Correct Answer: B

Rationale: When a client is on a soft diet, it is important to offer foods that are easy to chew and swallow. Mashed potatoes are a suitable choice for a soft diet as they are soft in texture and easy to digest. Fresh apples, raw carrots, and nuts are harder and may not be appropriate for a soft diet. Fresh apples and raw carrots require more chewing, and nuts are hard and crunchy, which can be difficult for someone on a soft diet to consume. Therefore, mashed potatoes are the correct option for a client on a soft diet.

Correct Answer: C

Rationale: The correct instruction for the nurse to include during postoperative teaching following a hip arthroplasty is to 'Place a pillow between your legs when turning.' Placing a pillow between the legs when turning is crucial as it helps prevent dislocation of the hip prosthesis. This position aids in maintaining proper alignment and stability, thereby reducing the risk of complications after hip arthroplasty surgery. Choices A, B, and D are incorrect because they do not directly address the specific action needed to protect the hip prosthesis and prevent complications.

Correct Answer: C

Rationale: When following a low-fat diet, it is essential to choose foods that are low in fat. Chicken breast is a lean protein source that is low in fat, making it a suitable option for a low-fat diet. Bacon, whole milk, and cheese are higher in fat content and should be avoided or limited in a low-fat diet. Bacon is high in saturated fat, whole milk contains significant amounts of fat, including saturated fat, and cheese is also high in fat. Therefore, these options are not ideal for a low-fat diet.

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.
