Pediatric HESI Test Bank

Correct Answer: B

Rationale: Chest tubes are necessary after open-heart surgery to facilitate the drainage of air and fluid from the chest cavity. These tubes help prevent complications such as pneumothorax (accumulation of air in the pleural space) or cardiac tamponade (build-up of fluid in the pericardial sac), which can be serious postoperative issues. Options A, C, and D are incorrect because chest tubes are primarily used for draining purposes and not for increasing tidal volumes, maintaining positive intrapleural pressure, or regulating pressure on the pericardium and chest wall.

Correct Answer: C

Rationale: In a child diagnosed with acute glomerulonephritis, monitoring urine output is a crucial assessment. Acute glomerulonephritis affects the kidneys, leading to decreased urine output due to impaired kidney function. Monitoring urine output helps assess renal perfusion, fluid status, and kidney function. This assessment is essential in determining the effectiveness of treatment and identifying complications. Monitoring blood glucose levels (Choice A) is not directly related to acute glomerulonephritis. Respiratory rate (Choice B) may be important in other conditions but is not a key assessment for acute glomerulonephritis. Monitoring for signs of infection (Choice D) is important in general, but it is not specific to the primary issue of impaired kidney function in acute glomerulonephritis.

Correct Answer: A

Rationale: In this scenario, the infant is showing signs of shock with increased work of breathing. Lowering the extremities helps improve venous return to the heart, cardiac output, and oxygenation by reducing the pressure on the diaphragm. This action can alleviate the respiratory distress and is a critical step to take in a child with signs of shock. Beginning positive pressure ventilations (Choice B) should be considered if the infant's respiratory distress worsens despite lowering the extremities. Placing a nasopharyngeal airway and increasing oxygen flow (Choice C) may not directly address the increased work of breathing or the underlying shock condition. Listening to the lungs with a stethoscope (Choice D) may provide information on lung sounds but does not address the immediate need to improve breathing in a child with signs of shock.

Correct Answer: A

Rationale: Encouraging regular physical activity is crucial in managing symptoms and improving joint function in juvenile idiopathic arthritis. It helps maintain joint mobility, muscle strength, and overall well-being. Providing a high-calorie diet (Choice B) is not typically recommended unless there are specific nutritional concerns or growth issues. A low-sodium diet (Choice C) may be beneficial in conditions like hypertension, but it is not a primary focus for JIA management. Administering intravenous fluids (Choice D) is not a routine part of managing JIA unless specifically indicated for hydration or medication administration.

Correct Answer: B

Rationale: The correct initial action during a tonic-clonic seizure is to place the child on the floor to prevent injury. This action helps protect the child from falling off the chair and provides a safer environment for the seizure to occur. Attempting to open the jaw can cause harm or injury. Calling out for assistance is important but should follow the immediate action of moving the child to the floor. Placing a pillow under the child's head is not recommended as it may lead to airway obstruction or further injury during the seizure.
