What is an appropriate initial treatment for a patient with a suspected pulmonary embolism?

• A. Administer anticoagulants
• B. Start oxygen therapy
• C. Perform immediate surgery
• D. Monitor symptoms and wait

Answer: (B)

In the context of a suspected pulmonary embolism (PE), the appropriate initial treatment involves several important considerations. Starting oxygen therapy is a critical first step as it addresses potential hypoxemia that may arise from the impaired pulmonary circulation due to the embolism. Patients with a PE often present with symptoms of shortness of breath and may have reduced oxygen saturation levels. By administering supplemental oxygen, healthcare providers can help stabilize the patient and improve oxygen delivery to vital organs.

While administering anticoagulants is also a key part of treating a pulmonary embolism, it is often initiated after initial assessment and stabilization of the patient, which may include starting oxygen therapy. Surgical interventions and watchful waiting are not appropriate first-line treatments in this acute situation, as they can be risky or detrimental to the patient's immediate well-being. Hence, initiating oxygen therapy is crucial in the urgent management of a suspected pulmonary embolism to stabilize the patient before further interventions.
