Wells Criteria for Pulmonary Embolisms [PEs] EXPLAINED

The video tutorial covers the signs and symptoms of pulmonary embolism (PE) and explains the Wells criteria used to predict the likelihood of a PE. It highlights the importance of distinguishing between symptoms of PE and other conditions like myocardial infarction. The tutorial also details the scoring system of the Wells criteria, emphasizing the significance of clinical signs such as deep vein thrombosis (DVT), elevated heart rate, and recent surgery or immobilization. The video aims to provide a comprehensive understanding of PE symptoms and the application of the Wells criteria in clinical practice.

What is the primary difference between the Wells criteria for DVT and PE?

• The criteria for DVT are only used in emergency settings.

• The criteria for DVT are used for diagnosis, while PE criteria are used for treatment.

• The criteria for DVT focus on leg symptoms, while PE criteria focus on lung symptoms.

• The criteria for DVT are more complex than those for PE.

Which symptom is most commonly associated with pulmonary embolism?

• Orthopnea

• Coughing up blood

• Dyspnea at rest or with exertion

• Sharp chest pain

How can pleuritic pain in PE be distinguished from myocardial infarction?

• PE pain is always accompanied by a cough.

• PE pain is sharp, while MI pain is more of a pressure.

• PE pain is localized to the left side of the chest.

• PE pain is more of a pressure sensation.

What is the most common sign of a pulmonary embolism?

• Calf swelling

• Tachycardia

• Jugular vein distention

• Tachypnea

Why might jugular vein distention occur in a patient with a pulmonary embolism?

• Due to increased blood flow to the neck veins

• Due to an infection in the neck

• Because of a backup of blood in the pulmonary arteries

• As a result of dehydration

What is the significance of a Wells score of 5.5 in a patient?

• The patient should be monitored for other conditions.

• The patient is likely to have a pulmonary embolism.

• The patient has a moderate risk of a pulmonary embolism.

• The patient is unlikely to have a pulmonary embolism.

Which factor contributes 1.5 points to the Wells criteria for PE?

• Hemoptysis

• Alternative diagnosis less likely

• Recent surgery or immobilization

• Active cancer
