Patient Data

 

Complete the diagram by dragging from the choices below to specify what condition the client is most likely experiencing, 2 actions the nurse should take to address that condition, and 2 parameters the nurse should monitor to assess the client's progress.

Pulmonary embolism management transitions from acute anticoagulation to long-term prevention and risk factor modification. A pulmonary embolism occurs when a thrombus, often from a deep vein, obstructs pulmonary arterial flow, leading to ventilation-perfusion mismatch and potential right heart strain. Discharge education focuses on hemorrhage prevention while on anticoagulants, enhancing peripheral venous return to prevent stasis, and addressing modifiable factors like nicotine use that promote a prothrombotic state.

Rationale:

A. Avoiding aspirin is essential because it is an antiplatelet agent that increases the risk of bleeding when combined with anticoagulants. The concurrent use of multiple blood-thinning medications significantly elevates the potential for gastrointestinal hemorrhage or intracranial bleeding. Clients must be taught to screen over-the-counter medications for hidden salicylates to maintain pharmacological safety during the recovery period.

B. Moving and stretching the lower extremities prevents venous stasis, a primary component of Virchow’s triad. Frequent movement facilitates the skeletal muscle pump, which assists in pushing venous blood back toward the heart and prevents the formation of new thrombi. This is especially critical for a client with a recent lower extremity fracture and cast who has reduced mobility.

C. Keeping legs in a dependent position is contraindicated because it promotes venous pooling and increases the risk of deep vein thrombosis. The client should be encouraged to elevate the legs above the level of the heart to facilitate venous drainage and reduce generalized edema. Dependent positioning worsens stasis and creates an environment conducive to further clot formation.

D. Smoking cessation is highly encouraged because nicotine causes vasoconstriction and hypercoagulability, increasing the risk of recurrent thromboembolic events. This client has a significant smoking history, which likely contributed to the development of the pulmonary embolism post-surgery. Quitting smoking is a vital lifestyle modification to improve vascular health and prevent future life-threatening complications.

E. Reporting shortness of breath is a priority instruction as it may indicate a recurrent embolism or worsening pulmonary function. Since the client already experienced an acute event characterized by respiratory distress, he must be vigilant in recognizing early symptoms. Prompt reporting allows for immediate clinical evaluation and prevents the progression of potential pulmonary infarction or failure.

F. Performing range of motion exercises maintains joint flexibility and promotes circulation while the client is convalescing. These exercises help prevent the complications of immobility-induced stasis, which is a high risk given his recent ankle fracture and surgery. Consistent movement ensures that blood flow remains active in the unaffected and partially affected limbs to support recovery.

G. Avoiding anal intercourse is a specific safety precaution to prevent mucosal trauma and subsequent rectal bleeding while on anticoagulation therapy. The rectal mucosa is highly vascular and easily injured, leading to significant blood loss if the client's clotting ability is pharmacologically suppressed. This instruction is a necessary component of comprehensive education regarding the prevention of internal bleeding.

H. Applying warm moist heat to fresh bruising is contraindicated as it causes vasodilation and can worsen local bleeding and hematoma expansion. Instead, clients should apply cold compresses to new bruises to promote vasoconstriction and limit the size of the hemorrhage. Heat should only be used in later stages of healing once the initial clot has stabilized.

The Allen's test evaluates ulnar artery patency to ensure adequate collateral circulation to the hand before radial artery puncture. It prevents ischemic necrosis by confirming that the ulnar artery can maintain distal perfusion if the radial artery undergoes thromboembolism or vasospasm, which are common complications during invasive percutaneous procedures.

Rationale:

A. Assessing for a deep vein thrombus involves Homans sign or ultrasound imaging, not a manual arterial compression test. The Allen's test is specific to upper extremity arterial flow and does not evaluate the venous system or lower limb pathology. It is irrelevant for diagnosing deep vein clots or pulmonary embolism risks.

B. Pulmonary artery pressures are measured via a Swan-Ganz catheter inserted through a large central vein like the internal jugular. This procedure does not involve radial artery access, making the Allen's test unnecessary. Monitoring these pressures focuses on hemodynamic stability and right heart function rather than peripheral collateral arterial circulation.

C. Before performing an ABG, the nurse must ensure the ulnar artery provides sufficient blood flow. The nurse compresses both arteries, asks the client to fist, then releases the ulnar side to check for palmar blushing within 5 to 15 seconds. This confirms collateral integrity, protecting the hand from potential radial artery injury.

D. Cardiac output calculations usually require thermodilution techniques or echocardiography rather than a peripheral arterial puncture. While an arterial line might be used for continuous monitoring, the Allen's test specifically precedes radial site utilization. It is not a prerequisite for standard calculations of stroke volume or systemic vascular resistance.
