After a walking pulse oximetry revealed saturation of 82% and a heart rate of 118, patient was admitted from a physician’s office to the emergency room. The patient was at the physician’s office for follow up of a recent outpatient surgical procedure and is suspected of having a pulmonary embolism.

What would be the most beneficial recommendation at this point?
  1. Continuous pulse oximetry
  2. Heparin therapy
  3. CT scan of the chest
  4. PET scan of the chest
Explanation
Answer: B-The patient should be placed on oxygen at 100% and started on heparin therapy.

Heparin assists in dissolving pulmonary embolisms. The patient will need to undergo a VQ scan for further confirmation. If confirmed, the patient will be placed on an oral anticoagulant.
