Fundamentals of Nursing HESI

Correct Answer: A

Rationale: Elevating the head of the bed to 30-45 degrees is crucial in reducing the risk of aspiration because it helps keep the gastric contents lower than the esophagus, thereby promoting proper digestion and preventing reflux. This position also aids in reducing the likelihood of regurgitation and aspiration of gastric contents. Checking residual volumes every 4 hours is important for monitoring feeding tolerance but does not directly address the risk of aspiration. Verifying tube placement every shift is essential for ensuring the tube is correctly positioned within the gastrointestinal tract but does not directly reduce the risk of aspiration. Flushing the tube with water every 4 hours may help maintain tube patency and prevent clogging, but it does not specifically address the risk of aspiration associated with nasogastric tube feedings.

Correct Answer: C

Rationale: During a mass casualty event, the priority client for the nurse is the one with partial-thickness and full-thickness burns to the face, neck, and chest. Clients with severe burns in critical areas require immediate attention due to the potential for life-threatening complications such as airway compromise, fluid loss, and infection. Crush injuries and fractures, although serious, are generally less urgent in comparison and can be managed after addressing the burns. Therefore, the client with burns to the face, neck, and chest should be the nurse's priority over the other clients described.

Correct Answer: D

Rationale: The priority action for the nurse is to address the client's immediate physiological need for comfort and pain relief during the dressing change. Administering pain medication 45 minutes before the procedure can help alleviate the pain experienced by the client. Encouraging relaxation techniques (choice A) is beneficial but may not provide sufficient pain relief during the dressing change. Educating about the importance of pain management (choice B) is relevant but does not address the immediate need for pain relief. Assisting the client to a comfortable position (choice C) is helpful but does not directly address the client's pain concern during the dressing change. Administering pain medication is the most direct and effective intervention to ensure optimal client comfort and compliance with necessary procedures.

Correct Answer: A

Rationale: Calf swelling is a common sign of thrombophlebitis, which is inflammation of a vein due to a blood clot. Prolonged immobility can predispose individuals to thrombophlebitis. Calf swelling occurs due to the obstruction of blood flow, causing localized edema. This condition can lead to serious complications like pulmonary embolism if not promptly addressed. Elevated blood pressure, decreased urine output, and a generalized rash are not typically associated with thrombophlebitis. Elevated blood pressure may be linked to other conditions like hypertension, decreased urine output to kidney dysfunction, and a generalized rash to allergic reactions or skin conditions. Therefore, in a client on bed rest, calf swelling should raise suspicion of thrombophlebitis and prompt further evaluation and intervention.

Correct Answer: A

Rationale: The correct answer is walking briskly. Weight-bearing exercises, such as brisk walking, are recommended for individuals at risk for osteoporosis because they help maintain bone mass and prevent bone loss. Riding a bicycle and performing isometric exercises are not weight-bearing activities, and therefore, may not provide the same bone-strengthening benefits as walking. High-impact aerobics can increase the risk of fractures in individuals with osteoporosis due to the high level of impact involved.
