Correct Answer: D

Rationale: Intussusception is a condition in which a proximal segment of the bowel telescopes or prolapses into a distal segment of the bowel. This leads to bowel obstruction and potential ischemia. It is not an acute bowel obstruction, as the obstruction is caused by the telescoping of bowel segments rather than a blockage in the bowel lumen. Intussusception is not primarily an inflammatory process; instead, it is a mechanical issue involving bowel invagination. Choice A is incorrect as it does not accurately describe the pathophysiology of intussusception. Choice C is incorrect because it presents the opposite scenario of what happens in intussusception.

Correct Answer: D

Rationale: Esophageal atresia with tracheoesophageal fistula is a critical neonatal surgical emergency. The highest priority intervention during the preoperative period is to aspirate the NG tube every 5 to 10 minutes to keep the proximal pouch clear of secretions and prevent aspiration. This is crucial in reducing the risk of gastric secretions entering the lungs. Repositioning the infant frequently is not as critical as ensuring the NG tube is aspirated. Monitoring the temperature and blood pressure are important nursing interventions but are not the highest priority in this situation. It is essential to prioritize airway protection and prevent aspiration in this neonate undergoing urgent surgical intervention.

Correct Answer: A

Rationale: In a patient presenting with dyspnea, dependent edema, rales, distended neck veins, and developing cardiac dysrhythmias, the priority intervention is to ensure the airway is open and unobstructed. Maintaining an open airway is crucial for adequate ventilation and oxygenation, especially in a patient showing signs of impending respiratory distress and cardiac compromise. While applying oxygen to maintain oxygen saturation is important, ensuring airway patency takes precedence as it directly impacts the patient's ability to breathe. Administering Dobutamine may be necessary to improve cardiac output; however, addressing the airway first is essential to prevent further respiratory distress and worsening dysrhythmias. Starting an IV for monitoring fluid intake is not the most critical intervention in this scenario compared to ensuring airway patency and oxygenation.

Correct Answer: C

Rationale: In the management of acute bronchitis, antibiotics are not typically prescribed unless there is a confirmed bacterial infection. Acute bronchitis is usually caused by a virus, so antibiotics are not effective in treating it. The primary focus is on symptom management and supportive care. Increased fluid intake helps keep the airway moist and liquefy secretions, aiding in their removal. Cough medications can help relieve cough symptoms. The use of a vaporizer can help moisten the air, making breathing more comfortable for the patient. It is crucial to differentiate between viral and bacterial causes of respiratory infections to avoid unnecessary antibiotic use and prevent antibiotic resistance. Therefore, the correct answer is 'Antibiotics.' Increased fluid intake, cough medications, and the use of a vaporizer are commonly recommended for managing symptoms and improving comfort in patients with acute bronchitis.

Correct Answer: C

Rationale: In the scenario presented, the priority nursing goal for a client with renal calculi experiencing moderate to severe flank pain and nausea should be to manage pain. Pain management is crucial as it alleviates suffering, improves comfort, and enhances the quality of life for the client. In the case of ureteral colic from renal calculi, the cornerstone of management is effective pain control. Prompt analgesia, typically achieved with parenteral narcotics or nonsteroidal anti-inflammatory drugs (NSAIDs), is essential to provide relief and facilitate the passage of the calculi. While maintaining fluid and electrolyte balance is important in clients with renal calculi, addressing pain takes precedence as it directly impacts the client's immediate well-being. Controlling nausea and preventing urinary tract infections are also important aspects of care, but they are secondary to managing the primary concern of pain in this urgent situation.
