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. 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: 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: A

Rationale: The correct answer is A. Increasing intake of iodine-rich foods is beneficial for clients with hypothyroidism as iodine is essential for thyroid hormone synthesis. Adequate iodine intake helps to support thyroid function in individuals with hypothyroidism, making choice A the most appropriate response indicating an understanding of the dietary management for this condition. Choices B, C, and D are incorrect because decreasing iodine-rich foods, increasing potassium-rich foods, or decreasing sodium-rich foods are not the recommended dietary modifications for hypothyroidism. In fact, decreasing iodine-rich foods could exacerbate hypothyroidism due to the essential role of iodine in thyroid hormone production.

Correct Answer: D

Rationale: During an abdominal assessment, the correct sequence of steps is inspection, auscultation, percussion, and palpation. This sequence is followed to prevent altering bowel sounds. Inspection allows for visual observation, followed by auscultation to listen for bowel sounds without causing disturbance, percussion to assess for tympany or dullness, and finally palpation to feel for any abnormalities or tenderness. Choice A is incorrect because palpation should come after percussion. Choice B is incorrect as auscultation should be performed after inspection. Choice C is incorrect because palpation should be the final step after percussion.
