Pulmonary Embolism Support Group
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.
I guess it depends on the doctor.

Cavey, despite your well intentions, there are resources available which should be suggested to patients (through links) rather then reposting information directly. Short answers are great, beyond that, refer people to a legitimate sources, whether that be the National Blood Clot Alliance (www.stoptheclot.org), Clot Connect (www.clotconnect.org), Mayo Clinic, NIH, etc.
Short answer is already known - "keep it in your diet, eat within moderation". Anything else should be referred to the above mentioned website for clarification.

"Can vitamin K affect my INR?
Yes, your INR refers to the international normalized ratio test, a standardized way to measure how your blood is clotting.
The lower your INR, the more quickly the blood clots or the thicker the blood. The higher your INR, the longer it takes the blood to clot or the thinner the blood, putting you at risk for bleeding problems.
With an increase in vitamin K your INR level may drop. Conversely, a decrease in vitamin K intake may increase the INR.
Other things, like medications, antibiotics, and herbal products may also influence your INR."
