PALS CPR RESPIRATORY DISTRESS & FAILURE EXAM Q & A 2024

PALS CPR Respiratory Distress & Failure Exam Q & A 2024 1. Which of the following is a common clinical manifestation of respiratory distress? A. Bradycardia B. Hypotension C. Tachypnea D. Hyperglycemia Answer: C. Tachypnea Rationale: Tachypnea, or rapid breathing, is a common sign of respiratory distress as the body tries to compensate for inadequate oxygenation. 2. Which of the following is a common cause of r espiratory failure? A. Pneumonia B. Hypertension C. Dehydration D. Diabetes Answer: A. Pneumonia Rationale: Pneumonia is an infection of the lungs that can lead to respiratory failure if left untreated. 3. How is respiratory distress differentiated from respiratory failure? A. Respiratory distress involves difficulty breathing, while respiratory failure indicates complete cessation of breathing. B. Respiratory distress is a less severe form of breathing difficulty compared to respiratory failure. C. Respi ratory failure requires immediate intervention to maintain oxygenation and prevent further complications. D. There is no difference between respiratory distress and respiratory failure. Answer: B. Respiratory distress is a less severe form of breathing difficulty compared to respiratory failure. Rationale: Respiratory distress indicates increased effort in breathing, while respiratory failure is the inability to maintain adequate oxygenation. 4. Which of the following can be a potential complication of un treated respiratory distress? A. Hypertensive crisis B. Pulmonary edema C. Hypernatremia D. Hypoglycemia Answer: B. Pulmonary edema Rationale: Pulmonary edema can develop as a result of fluid accumulation in the lungs due to inadequate oxygenation in case s of untreated respiratory distress. 5. How is respiratory failure managed in a clinical setting? A. Oxygen therapy to improve oxygenation B. Administering intravenous fluids to support respiratory function C. Immediate intubation and mechanical ventilati on D. Monitoring blood glucose levels to prevent hypoglycemia Answer: C. Immediate intubation and mechanical ventilation Rationale: Respiratory failure requires immediate intervention with intubation and mechanical ventilation to support breathing and mai ntain adequate oxygenation. 6. What is the normal range for partial pressure of oxygen (PaO2) in arterial blood gas (ABG) analysis? A. 20 -40 mmHg B. 60 -100 mmHg C. 120 -160 mmHg D. 180 -220 mmHg Answer: B. 60 -100 mmHg Rationale: The normal range for PaO2 in ABG analysis is 60 -100 mmHg, indicating adequate oxygenation of arterial blood. 7. Which of the following is a characteristic feature of acute respiratory distress syndrome (ARDS)? A. Increased lung compliance B. Preserved gas exchange C. Bilateral pul monary infiltrates on chest X -ray
