Question

What is the next line of management for a 25 year old woman who develops acute pulmonary embolism?

• A. Thrombolysis
• B. LMW heparin
• C. Oral anticoagulants
• D. IVC filter

Hint:

A life threatening PE needs clot dissolving therapy, not just clot prevention.

Answer 1

The Correct Option is A

Step 1: Note what the question is really asking.
The phrase "next line of management" points to a patient who already has a confirmed diagnosis of acute pulmonary embolism (PE) and needs urgent, life saving treatment right now, not a routine follow up step.

Step 2: Recall how PE treatment is chosen.
Treatment depends on how sick the patient is. A stable patient, with normal blood pressure and no major right heart strain, is treated with anticoagulation, usually low molecular weight heparin (LMWH), followed later by oral anticoagulants. An unstable patient, with hypotension, shock, or severe right ventricular strain, needs the clot broken down fast, since the embolism itself is the immediate threat to life.

Step 3: Apply this to a severe, acute PE.
When a question frames PE as needing urgent "next" management, it is pointing at this high risk, massive PE picture, where the clot is large enough to obstruct blood flow and threaten the patient's life. In that setting, dissolving the clot takes priority over simply preventing new clot.
Thrombolysis, using drugs such as streptokinase, urokinase, or alteplase, dissolves the clot directly and restores blood flow through the pulmonary arteries quickly, something heparin cannot do since heparin only stops new clot from forming.

Step 4: Rule out the other options.
LMW heparin prevents the clot from growing further, and is right for a stable patient, but it will not rescue someone already in shock from a large pulmonary artery blockage.
Oral anticoagulants such as warfarin take several days to reach a useful blood level, so they are never used as urgent first line therapy.
An IVC filter only stops new clots travelling up from the leg veins, it does nothing to a clot that is already lodged in the pulmonary artery.

Final Answer:
For an acute, life threatening pulmonary embolism, thrombolysis is the immediate next step in management. \[ \boxed{\text{Thrombolysis}} \]
