LPN Fundamentals Practice Questions

Correct Answer: A

Rationale: The correct answer is A. Increasing intake of high-fiber foods is essential in managing diverticulitis as it helps prevent constipation and promotes bowel regularity, reducing the risk of complications and improving overall colon health. Choice B is incorrect because decreasing high-fiber foods can worsen diverticulitis symptoms. Choices C and D are also incorrect as increasing high-fat foods can exacerbate diverticulitis, while decreasing high-fat foods is generally recommended to manage the condition.

Correct Answer: B

Rationale: To prevent dislocation of the hip prosthesis, the client should avoid bending their hips more than 90 degrees. Excessive bending at the hips can increase the risk of hip dislocation, which is a significant concern following total hip arthroplasty. Sitting with crossed legs at the ankles (choice A) can also increase the risk of hip dislocation and should be avoided. Sitting in a low-seated chair (choice C) can make it more challenging for the client to stand up safely. Twisting the body when standing up (choice D) can also strain the hip joint and increase the risk of dislocation. Therefore, the correct instruction to include during discharge teaching is to avoid bending the hips more than 90 degrees.

Correct Answer: B

Rationale: The correct answer is B because reducing dairy product intake can help manage symptoms of ulcerative colitis. Dairy products can exacerbate symptoms in some individuals due to their lactose content and may need to be limited or avoided based on individual tolerance levels. Choice A is incorrect because increasing dairy products can worsen symptoms for some ulcerative colitis patients. Choice C is incorrect as while high-fiber foods are generally beneficial, they may exacerbate symptoms during a flare-up. Choice D is also incorrect as while reducing high-fat foods can be beneficial, dairy products are a more specific concern for ulcerative colitis.

Correct Answer: B

Rationale: When administering a subcutaneous injection, inserting the needle at a 90-degree angle is appropriate. This angle helps ensure proper delivery of the medication into the subcutaneous tissue. Using a 1-inch needle is common for subcutaneous injections to reach the subcutaneous fat layer adequately. Tuberculin syringes are typically used for intradermal injections, not subcutaneous injections. Aspirating before injecting is not necessary for subcutaneous injections as it is primarily used for intramuscular injections to ensure the needle is not in a blood vessel.

Correct Answer: B

Rationale: Correct! Hyperkalemia is a condition characterized by high levels of potassium in the blood. To manage hyperkalemia, it is essential to decrease the intake of potassium-rich foods since excess potassium can worsen the condition. By understanding the need to decrease potassium-rich foods, the client shows comprehension of the dietary management required for hyperkalemia. Choice A is incorrect because increasing potassium-rich foods would exacerbate hyperkalemia. Choice C is incorrect since increasing sodium-rich foods is unrelated to managing hyperkalemia and could potentially lead to other health issues. Choice D is incorrect as decreasing sodium-rich foods is not the primary focus when managing hyperkalemia.
