Deep vein thrombosis - Nursing Case Study

Pathophysiology

• Primary mechanism: Blood stasis - Occurs when blood flow is slowed or halted, often due to immobility or prolonged bed rest, leading to clot formation in deep veins, usually in the legs.

• Secondary mechanism: Hypercoagulability - An increased tendency for blood to clot, which can be due to genetic factors, certain medications, or medical conditions, further promoting clot formation.

• Key complication: Pulmonary embolism - A potentially life-threatening condition where a part of the clot breaks off and travels to the lungs, blocking blood flow and causing respiratory issues.

Section 1

Initial Assessment Findings:

Upon arrival at the clinic, the nurse conducts a thorough assessment of the patient, focusing on the lower extremities. The patient reports mild, persistent calf pain that she describes as a dull ache, exacerbated by walking or standing for extended periods. Upon inspection, there is noticeable swelling of the right calf compared to the left, with a circumference difference of approximately 2 cm. The skin over the affected area appears slightly reddened and is warm to the touch. Palpation reveals tenderness localized to the posterior aspect of the calf, particularly along the course of the deep veins. The Homans' sign test is performed, which elicits discomfort when the foot is dorsiflexed, further supporting suspicions of deep vein thrombosis (DVT).

Vital signs remain stable, with no significant changes noted since the initial presentation. The blood pressure is 120/80 mmHg, heart rate is 78 bpm, respiratory rate is 16 breaths/min, and temperature is 98.6°F (37°C). The patient denies any shortness of breath or chest pain, and her oxygen saturation is 98% on room air. These findings suggest that, while the DVT is present, there is no immediate evidence of pulmonary embolism, a serious complication that requires urgent intervention.

The nursing team decides to initiate a Doppler ultrasound of the affected leg to confirm the presence of a thrombus in the deep veins and assess its extent. The patient is educated on the importance of early detection and treatment to prevent progression and reduce the risk of complications. The nurse emphasizes the need for regular monitoring and adherence to prescribed interventions, such as anticoagulation therapy, to manage the condition effectively and safely.

Section 2

New Diagnostic Results:

The Doppler ultrasound of the right leg is performed and confirms the presence of a thrombus within the deep venous system, specifically involving the popliteal vein. The thrombus is non-occlusive, indicating partial blood flow is still present, which is consistent with the patient's stable presentation and lack of severe symptoms. The radiologist notes no indication of extension into the more proximal veins, which reduces the immediate risk of embolization. These findings corroborate the initial clinical assessment and reinforce the need for anticoagulation therapy to prevent further clot formation and potential complications.

Laboratory tests are also conducted as part of the diagnostic workup. The patient's D-dimer levels are elevated at 1.2 μg/mL (normal <0.5 μg/mL), supporting the presence of an active clotting process. Complete blood count (CBC) reveals no significant abnormalities, with hemoglobin at 13.5 g/dL, white blood cell count at 7,000/mm³, and platelets at 250,000/mm³. Renal function tests are within normal limits, indicating that the patient is a suitable candidate for anticoagulation therapy without dose adjustments for renal impairment.

Given these diagnostic results, the healthcare team decides to initiate anticoagulation therapy with low molecular weight heparin (LMWH) to reduce the risk of clot progression and potential embolization. The patient is instructed on self-administration techniques and the importance of adhering to the treatment regimen. The nurse also emphasizes monitoring for signs of bleeding, such as unusual bruising or blood in the urine, as well as the need for regular follow-up appointments to assess treatment effectiveness and adjust the plan as necessary. The patient expresses understanding of the treatment plan and agrees to maintain communication with the healthcare team regarding any new symptoms or concerns.

Section 3

Response to Interventions:

After initiating anticoagulation therapy with low molecular weight heparin (LMWH), the patient returns for a follow-up appointment one week later. During the visit, the nurse conducts a thorough assessment to evaluate the patient's response to the treatment and to identify any potential complications. The patient reports feeling generally well, with no significant discomfort or new symptoms since starting the medication. However, they mention noticing some minor bruising around the injection sites on their abdomen, which they describe as small and not painful.

Vital signs are stable: blood pressure is 118/76 mmHg, heart rate is 78 beats per minute, respiratory rate is 16 breaths per minute, and temperature is 98.6°F. The patient's right leg, where the thrombus was identified, is examined. There is mild swelling below the knee, but it has decreased slightly compared to the initial presentation. The skin is warm and intact without any signs of redness or increased tenderness. These findings suggest that the anticoagulation therapy is having a positive effect, with no evidence of significant bleeding complications.

The nurse reviews the importance of adherence to the treatment regimen with the patient, reinforcing the need to continue with LMWH as prescribed. The patient is reminded to monitor for any signs of serious bleeding, such as unusual nosebleeds or prolonged bleeding from cuts. The healthcare team plans to conduct routine blood tests, including monitoring the platelet count and assessing renal function, to ensure the continued safety and effectiveness of the therapy. The patient is reassured and expresses confidence in managing their condition with the ongoing support of the healthcare team.

Section 4

A week after the initial follow-up, the patient returns for another scheduled appointment to monitor their progress on the low molecular weight heparin therapy. During this visit, the nurse conducts a comprehensive assessment to detect any changes in the patient's condition. The patient reports feeling well overall, with continued adherence to the prescribed medication regimen. However, they notice persistent bruising at the injection sites and have experienced mild, occasional headaches over the past few days. Despite these symptoms, the patient denies any dizziness, visual disturbances, or significant changes in their daily activities.

Vital signs remain stable: blood pressure reads 116/74 mmHg, heart rate is 80 beats per minute, respiratory rate is 18 breaths per minute, and temperature is 98.7°F. Upon examination of the right leg, the nurse notes a slight reduction in swelling compared to the previous visit, and the skin remains warm and intact without redness or increased tenderness. Laboratory results from routine blood tests show a stable platelet count within normal range, and renal function tests indicate normal kidney function, which suggests that the patient is tolerating the anticoagulation therapy well.

The nurse addresses the patient's concerns about the bruising and mild headaches, explaining that these are common side effects of anticoagulation therapy. The patient is advised to use a cold compress on the bruises if they become bothersome and to keep a headache diary to monitor the frequency and severity of the headaches. The nurse emphasizes the importance of continuing to monitor for any signs of serious bleeding and stresses the need for regular follow-up appointments to ensure the ongoing effectiveness and safety of the treatment. The patient is reassured and encouraged to maintain open communication with the healthcare team, fostering confidence in managing their condition moving forward.

Section 5

Two weeks after the last appointment, the patient returns for another follow-up visit. This time, the patient reports feeling slightly more fatigued than usual, but attributes it to a busy week at work. The bruising at the injection sites has begun to fade, and the headaches have become less frequent and less severe, which the patient notes in their headache diary. However, they mention a new sensation of mild tingling in the toes of the affected leg, which has been present intermittently over the past few days. The patient denies any numbness or worsening of the previous symptoms.

During the assessment, vital signs remain stable, with blood pressure at 118/76 mmHg, heart rate at 82 beats per minute, respiratory rate at 18 breaths per minute, and temperature at 98.6°F. Upon examination, the nurse observes that the swelling in the right leg has continued to decrease, and there is no new bruising or changes in skin temperature or color. The tingling sensation prompts the nurse to perform a more detailed neurological assessment, which reveals no significant abnormalities in sensation, strength, or reflexes. The nurse suspects that the tingling might be related to the patient's positioning or recent activity level and advises them to monitor the sensation, ensuring to report any worsening or new symptoms promptly.

The nurse discusses the findings with the patient and reinforces the importance of continuing the anticoagulation therapy as prescribed. To address the fatigue, the nurse suggests balancing activity with rest and maintaining hydration. The patient is encouraged to keep track of any changes and to attend the next follow-up appointment as scheduled. This ongoing monitoring will help ensure that any new symptoms are addressed early, allowing for timely interventions and adjustments in the treatment plan if necessary. The patient leaves the appointment feeling reassured and better informed about managing their condition.
