LPN Fundamentals Practice Questions

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: 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: B

Rationale: Discharge planning should begin upon the client's admission to the care facility. This early start allows the healthcare team to conduct assessments, set goals, and coordinate services for a smooth transition back home or to the community. Initiating discharge planning early ensures timely arrangements, leading to optimal outcomes and continuity of care. Choices A, C, and D are incorrect because waiting until one week before discharge, after the discharge date is identified, or until the client brings up the topic may lead to rushed decision-making, inadequate arrangements, and a less effective transition process.

Correct Answer: C

Rationale: The correct answer is C: Lentils. Incomplete proteins lack one or more essential amino acids required for protein synthesis in the body. Examples of incomplete proteins include lentils, vegetables, grains, nuts, and seeds. Lentils, a plant-based protein source, are considered incomplete as they do not contain all essential amino acids in sufficient amounts. Choices A, B, and D are incorrect as eggs, soybeans, and yogurt are examples of complete proteins, containing all essential amino acids in the right proportions for the body's needs.

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.
