LPN Fundamentals of Nursing

Correct Answer: B

Rationale: Elevating the head of the bed to 30-45 degrees during feedings is essential to prevent aspiration in clients receiving enteral nutrition. This positioning helps decrease the risk of regurgitation and aspiration by supporting proper digestion and aiding food passage through the gastrointestinal tract. Elevating the head of the bed is a standard precautionary measure recommended to reduce the chances of aspiration and should be consistently implemented during feedings to ensure client safety and optimal enteral nutrition delivery.

Correct Answer: B

Rationale: The correct answer is B because increasing the intake of fresh fruits and vegetables can help manage blood pressure. These foods are rich in nutrients like potassium, fiber, and antioxidants, which are beneficial for individuals with hypertension. Dairy products are usually high in saturated fats, which can be detrimental to blood pressure control. Whole grains are generally recommended for their health benefits, including maintaining a healthy weight and heart health. Red meat is often high in saturated fats and can contribute to high blood pressure and other cardiovascular risks.

Correct Answer: A

Rationale: Shaking the inhaler before use is crucial to ensure proper mixing of the medication. This action helps distribute the medication evenly, allowing for consistent dosing with each use. It is a vital step in using a metered-dose inhaler correctly to optimize its effectiveness in managing respiratory conditions.

Correct Answer: C

Rationale: To ensure effective drainage, the catheter should be inserted 2-4 inches into the urethra. This length allows the catheter to reach the bladder, bypass the urethral sphincters, and ensure proper drainage without causing discomfort or injury. Using sterile gloves, cleaning the catheter with alcohol, and performing the procedure every 8 hours are not accurate instructions for self-catheterization.

Correct Answer: A

Rationale: Flushing the NG tube with 30 mL of water every 4 hours is crucial to maintain its patency and prevent blockages. This routine ensures the tube stays clear and functional, enabling proper delivery of medications and nutrition to the client. Regular flushing also helps prevent residue buildup or clogs within the tube, reducing risks like aspiration or inaccurate medication dosing.
