What nursing intervention is crucial for a client experiencing deep vein thrombosis who also shows signs of potential pulmonary embolism?

• A. Initiate continuous pulse oximetry
• B. Instruct the client to walk to promote circulation
• C. Ignore signs unless verified by a physician
• D. Delay administering oxygen until symptoms improve

Answer: (A)

Initiating continuous pulse oximetry is essential for a client experiencing deep vein thrombosis (DVT) with potential signs of pulmonary embolism (PE) because it allows for continuous monitoring of the client's oxygen saturation levels. Pulmonary embolism can lead to impaired gas exchange and significant decreases in oxygenation. By providing immediate feedback on the client’s respiratory status, the healthcare team can respond swiftly to any changes that may indicate the need for supplemental oxygen or other interventions. This monitoring is vital in detecting worsening respiratory distress or the need for further medical intervention, thus playing a crucial role in the safe management of the client’s condition.

In the context of this situation, other options would not prioritize the immediate assessment of the client’s oxygenation levels. Mobilizing the client might not be appropriate if they are already showing signs of PE, as it could increase the risk of worsening their condition. Ignoring symptoms can lead to delays in treatment, which is detrimental in an emergent situation like a potential PE. Delaying oxygen administration can also significantly compromise the patient's respiratory function, leading to possible adverse outcomes. Hence, continuous pulse oximetry is crucial for timely and effective intervention.
