The nursing care plan for a client in traction includes regular assessments for venous thromboembolism. When assessing a client’s lower limbs, what sign or symptom is suggestive of deep vein thrombosis (DVT)?
A.
Increased circulation of the calf
B.
Pale-appearing calf
C.
Increased warmth in the calf
D.
Loss of sensation to the calf
E.
Swelling and tenderness of the calf
The Correct Answer and Explanation is:
The correct answer is:
C. Increased warmth in the calf
Explanation:
Deep vein thrombosis (DVT) occurs when a blood clot forms in a deep vein, typically in the lower extremities, and is a serious condition that can lead to complications such as a pulmonary embolism (PE). Regular assessment of the client’s lower limbs is crucial for early detection of DVT, especially in individuals with risk factors like immobility due to traction, surgery, or injury.
Symptoms of DVT:
When assessing a client for DVT, one of the primary signs to watch for is increased warmth in the calf. This warmth results from inflammation in the area where the clot forms. The following signs and symptoms are also indicative of DVT:
- Swelling: One leg may appear more swollen than the other, particularly in the calf area. This is due to the blockage of blood flow caused by the clot.
- Tenderness or pain: The affected calf may be tender or painful to touch, especially when the foot is flexed (known as a positive Homans’ sign).
- Erythema (redness): The skin over the clot may become reddish or discolored.
- Firmness: The calf may feel firmer than usual due to the accumulation of blood behind the clot.
Increased warmth is one of the more subtle but significant signs of DVT. It occurs due to localized inflammation and the body’s immune response to the clot.
Other Incorrect Options:
- A. Increased circulation of the calf: DVT typically leads to decreased circulation, not increased.
- B. Pale-appearing calf: Pallor is uncommon in DVT and more indicative of arterial issues rather than venous ones.
- D. Loss of sensation to the calf: Neurological symptoms such as loss of sensation are not commonly associated with DVT. Sensory changes might indicate nerve damage, but not DVT.
Early recognition and prompt intervention are crucial in managing DVT and preventing life-threatening complications.
