LPN Fundamentals Practice Questions

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: A

Rationale: The correct answer is A. Increasing intake of foods high in vitamin D is beneficial for improving calcium absorption and managing osteoporosis. Vitamin D helps the body absorb calcium, which is essential for bone health and can aid in managing osteoporosis effectively. Choice B is incorrect because reducing calcium intake would be counterproductive for a client with osteoporosis, as calcium is crucial for bone strength. Choice C is incorrect as phosphorus, while important for bone health, does not directly impact osteoporosis management as much as vitamin D and calcium. Choice D is incorrect as potassium is not directly linked to osteoporosis management, and reducing its intake is not typically part of dietary recommendations for osteoporosis.

Correct Answer: A

Rationale: Hyperoxygenating the client before suctioning is crucial to prevent hypoxia during the procedure. By using a manual resuscitation bag with 100% oxygen, the nurse should provide several breaths to the client to ensure sufficient oxygenation before starting suctioning. This approach helps maintain oxygen levels and decreases the risk of hypoxia, which may arise when suctioning interrupts the normal respiratory process. Choices B, C, and D are incorrect because inserting the catheter during exhalation, applying suction while inserting the catheter, and limiting suctioning to 15 seconds do not address the priority of hyperoxygenating the client to prevent hypoxia.

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.

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.
