To determine which statement is incorrect regarding deep venous thrombosis (DVT), we must evaluate each option based on medical knowledge:
- Clinical assessment highly reliable: The clinical assessment of DVT can be a useful tool, but it is not always highly reliable on its own due to the variability in symptoms. It often requires confirmation with imaging techniques such as ultrasound. This statement is partially correct but somewhat misleading as a standalone claim.
- Mostly bilateral: DVT usually manifests in a unilateral fashion, affecting one leg rather than both. Bilateral involvement can occur but is not the norm. This statement is incorrect.
- Most common clinically presents as pain and tenderness in calf: DVT often presents with symptoms such as pain, swelling, and tenderness in the calf or affected area, making this a correct statement.
- Some cases may directly present as pulmonary thromboembolism: It is possible for DVT to first present as a pulmonary embolism if a clot dislodges and travels to the lungs. This statement is correct.
Based on these evaluations, the statement "Mostly bilateral" is the incorrect option regarding deep venous thrombosis.
