A nurse is caring for a client who has just developed a pulmonary embolism. Which of the following medications should the nurse anticipate administering?

A. Atropine is an anticholinergic used primarily for bradycardia or to reduce secretions during surgery, not for treating pulmonary embolism (PE). B. Heparin is an anticoagulant that helps prevent further clot formation and is commonly administered immediately after diagnosis of a PE to reduce the risk of complications. C. Furosemide is a loop diuretic used to treat fluid overload, such as in heart failure, but it does not address the underlying clot in PE. D. Dexamethasone is a corticosteroid used for inflammatory conditions, not for the treatment of pulmonary embolism.
