LPN Fundamentals Practice Questions

Correct Answer: C

Rationale: When following a low-fat diet, it is essential to choose foods that are low in fat. Chicken breast is a lean protein source that is low in fat, making it a suitable option for a low-fat diet. Bacon, whole milk, and cheese are higher in fat content and should be avoided or limited in a low-fat diet. Bacon is high in saturated fat, whole milk contains significant amounts of fat, including saturated fat, and cheese is also high in fat. Therefore, these options are not ideal for a low-fat diet.

Correct Answer: B

Rationale: Edema at the infusion site is an indication of infiltration, where fluid leaks into the surrounding tissues causing swelling. This can compromise the delivery of medication and fluids, potentially leading to complications. Redness, warmth, and oozing of blood are more suggestive of inflammation or infection rather than infiltration. Infiltration requires prompt recognition and intervention to prevent further issues with the IV therapy.

Correct Answer: C

Rationale: Positioning the client on their left side is crucial when administering an enema as it helps facilitate the flow of the solution into the sigmoid and descending colon. This position allows gravity to assist in the process. Placing the client on the left side is a standard practice to promote optimal outcomes during the procedure. Choices A, B, and D are incorrect. Choice A provides a specific measurement for the insertion depth of the rectal tube, which is not typically necessary to include in the plan of action. Choice B is essential but not specific to enema administration. Choice D mentions holding the solution bag without specifying the correct height, which should typically be around 18-24 inches above the rectum for a cleansing enema.

Correct Answer: B

Rationale: The correct answer is B because decreasing the intake of calcium-rich foods can help manage and prevent the formation of renal calculi. Excessive calcium intake can contribute to the formation of these stones, so reducing calcium-rich foods is a key dietary modification for individuals with renal calculi. Choice A is incorrect as increasing calcium-rich foods can exacerbate the condition. Choice C is incorrect because increasing sodium-rich foods can lead to more stone formation due to increased calcium excretion. Choice D is incorrect as potassium-rich foods do not directly contribute to the formation of renal calculi.

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.
