LPN Fundamentals Practice Questions

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: C

Rationale: The correct answer is C. The Dietary Approaches to Stop Hypertension (DASH) diet is recommended for managing hypertension. Increasing the intake of fruits and vegetables is a key component of the DASH diet as these foods are rich in nutrients that can help lower blood pressure levels. Choices A, B, and D are incorrect because they go against the principles of the DASH diet, which focuses on reducing sodium intake, increasing potassium-rich foods, and consuming whole grains.

Correct Answer: B

Rationale: Measuring the tube from the client's nose to the earlobe to the xiphoid process ensures the tube is inserted to the correct depth. This measurement helps prevent complications such as tube misplacement or lung insertion. Positioning the client with the head of the bed elevated to 30� is important to facilitate easier insertion but is not the most crucial step. Lubricating the entire length of the tube with water-soluble lubricant is essential for smooth insertion but is not the most critical action. Instructing the client to cough during insertion is not necessary and may lead to unnecessary discomfort.

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: D

Rationale: When collecting a stool specimen for ova and parasites, it is essential to place the specimen collection container in a biohazard bag. This practice ensures proper handling of potentially infectious material and prevents contamination with microorganisms. The biohazard bag should be labeled with the client's information for easy identification and proper tracking throughout the testing process. Instructing the client to defecate into a clean container is incorrect as it may introduce contaminants. Transferring the specimen to a sterile container is unnecessary and can increase the risk of contamination. Refrigerating the collected specimen is also not recommended as it may alter the sample and affect the test results.
