Which of the following is a component of pulmonary embolus management?

• A. Respiratory support
• B. Antibiotics
• C. Diuretic therapy
• D. Neuroleptics

Answer: (A)

Maintaining adequate oxygenation is essential in pulmonary embolism management because an embolus disrupts lung perfusion and can lead to rapid hypoxemia and respiratory distress. Providing respiratory support, such as supplemental oxygen and, if needed, advanced ventilation, helps keep maternal and fetal oxygen levels adequate and reduces the work of breathing. The other options don’t address gas exchange directly: antibiotics target infection, diuretics address fluid overload or heart failure, and neuroleptics have no role in treating PE. In practice, this respiratory support is used alongside anticoagulation and, for unstable cases, thrombolysis or embolectomy as part of comprehensive management.
