Question

When teaching about causes of deep vein thrombosis, the nurse would include:

Answers

  1. Arterial stasis, hypercoagulability, and arterial wall injury
    • Rationale:

      This answer choice is not correct because DVT is a venous, not an arterial issue.

  2. Myocardial infarction, stroke, and prolonged sitting
    • Rationale:

      This answer choice is not correct. Myocardial infarction and stroke result from blockage of a coronary artery. While prolonged sitting can contribute to DVT, the answer choice that addresses each area of Virchow’s triad is the most correct.

  3. Venous stasis, hypercoagulability, and venous wall injury
    • Rationale:

      This answer is correct because these three factors combine to form Virchow’s triad. Virchow’s triad addresses all factors which contribute to DVT formation.

  4. Motor vehicle accident and prolonged bed rest
    • Rationale:

      This answer choice is not correct because it does not address all the areas that may contribute to DVT formation.

Overview

The focus of this question is asking the nurse to identify the most appropriate teaching regarding underlying etiologies for development of deep vein thrombosis (DVT). There are three broad categories of factors that contribute to DVT which are collectively referred to as Virchow’s triad. These three factors are venous stasis, hypercoagulability, and/ or venous wall injury.

Explanation

Learning Outcomes

Virchow’s triad is an extremely important concept when examining the underlying causes for the development of DVT. The three factors included within Virchow’s triad are venous stasis, hypercoagulability, and venous wall injury. The most common contributor to venous stasis is immobility. Hypercoagulability often results when clients have cancer. Venous wall injury occurs following trauma.

Test Taking Tip

Virchow’s triad is a broad term addressing all potential causes of DVT. It is an umbrella concept for all the issues that could potentially cause venous stasis, hypercoagulability and/or venous wall injury.
