LPN Fundamentals Practice Questions

Correct Answer: C

Rationale: Assisting the client with early ambulation is crucial in preventing respiratory complications after abdominal surgery. Early ambulation helps to prevent conditions like atelectasis and pneumonia by promoting lung expansion and preventing pooling of respiratory secretions. It also aids in improving circulation, reducing the risk of deep vein thrombosis, and enhancing overall recovery. Instructing the client to exhale into an incentive spirometer (Choice A) is beneficial for lung expansion but is more focused on respiratory therapy rather than preventing complications. Repositioning the client every 8 hours (Choice B) is important for preventing pressure ulcers but is not directly related to preventing respiratory complications. Maintaining the client on bed rest for the first 48 hours (Choice D) can lead to complications such as atelectasis, pneumonia, and deep vein thrombosis due to decreased lung expansion and mobility.

Correct Answer: A

Rationale: The correct answer is A: 'I should avoid foods that contain gluten.' Celiac disease requires the avoidance of gluten-containing foods to manage symptoms and prevent complications. Gluten is found in wheat, barley, and rye. Choices B, C, and D are incorrect as they do not align with the dietary requirements for managing celiac disease. Increasing intake of foods high in gluten or lactose would be detrimental for someone with celiac disease.

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.

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: The correct answer is B. In hyperlipidemia management, decreasing the intake of foods high in cholesterol is crucial to improve lipid levels and reduce the risk of cardiovascular diseases. Choices A and C are incorrect as increasing intake of saturated fats or trans fats can raise cholesterol levels, worsening the condition. Choice D is incorrect because decreasing intake of foods high in fiber is not recommended as fiber-rich foods are beneficial for heart health, which is important in managing hyperlipidemia.
