Prescribing Safety Assessment (PSA) Practice Exam

Which of the following is NOT part of the management for Pulmonary Embolism (PE)?

1. LMWH - Tinzaparin 175 units/kg SC daily

2. Cyclizine 50mg IV

3. Metoprolol 50mg PO

4. High flow Oxygen

The correct answer is: Metoprolol 50mg PO

In the management of Pulmonary Embolism (PE), the main therapeutic goals include anticoagulation to prevent further clot formation and the management of symptoms associated with hypoxia and cardiovascular instability. Low Molecular Weight Heparin (LMWH), such as Tinzaparin, is a standard first-line treatment for PE as it provides effective anticoagulation. High flow oxygen is also critical, especially if the patient is experiencing significant hypoxemia, as it helps improve oxygen saturation and overall oxygen delivery to tissues. Cyclizine, as an antiemetic, may be used for symptomatic relief if the patient experiences nausea, particularly after the acute event or if they are in pain. Metoprolol, however, is primarily a beta-blocker used for controlling heart rate and managing conditions such as hypertension and heart failure. It does not directly address the acute management of PE or its associated complications, making it not a standard part of the immediate treatment regimen for this condition. Therefore, it stands out as not being a part of the standard management protocol for pulmonary embolism.
