Correct Answer: A

Rationale: Elevating the head of the bed to 30� is the correct action to take when a client is receiving continuous enteral feedings through a nasogastric tube. This position helps prevent aspiration of the enteral feedings into the lungs, reducing the risk of aspiration pneumonia. Additionally, elevating the head of the bed promotes proper digestion and absorption of the feedings by utilizing gravity to facilitate movement into the stomach and through the gastrointestinal tract. Flushing the tube with water every 2 hours (Choice B) is not necessary for continuous feedings and may disrupt the feeding schedule. Replacing the feeding bag and tubing every 72 hours (Choice C) is not the standard recommendation unless there are specific concerns or complications. Checking the client's gastric residual every 8 hours (Choice D) is important but not the immediate action needed to prevent aspiration during enteral feedings.

Correct Answer: C

Rationale: For infants and young children, the vastus lateralis muscle located over the anterior thigh is the preferred site for intramuscular injections. This site is chosen for its large muscle mass and reduced risk of injury to major nerves and blood vessels. Infants have less developed muscle structures, making the vastus lateralis a safer and more effective site for injections compared to other sites like the deltoid, ventrogluteal, or dorsogluteal. Using the correct injection site is essential to prevent complications and ensure the proper absorption of the medication.

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.
