LPN Fundamentals of Nursing

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: 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.

Correct Answer: B

Rationale: When a pressure ulcer is healing, there is a decrease in its size as the tissue repair progresses. This reduction in size is a positive indication of the healing process. An increase in drainage, presence of foul odor, or reddened wound edges are typically signs of infection or lack of improvement. Therefore, the correct answer is a decrease in size.

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: D

Rationale: Redness and warmth of the affected limb are classic signs of deep-vein thrombosis (DVT) due to inflammation and increased blood flow. These symptoms occur as a result of the blood clot obstructing normal blood flow and causing localized inflammation in the affected limb. Swelling of the affected limb, diminished peripheral pulses, and coolness are not typically associated with DVT. Swelling can be present but is often accompanied by the characteristic redness and warmth. Diminished pulses and coolness are more indicative of arterial insufficiency rather than venous thrombosis.
