If a client develops a pulmonary embolus after surgery, what is the priority for administering vancomycin?

Starting another IV line for vancomycin while continuing heparin is the priority intervention in this scenario. This approach ensures that both medications can be administered simultaneously without interference, which is critical because pulmonary embolism (PE) is a serious condition requiring immediate and effective management.

Using a separate IV line for vancomycin not only allows for uninterrupted heparin therapy, which is essential for managing and preventing further clot formation, but also ensures that the antibiotic can be delivered effectively if there is an infection risk, such as in the postoperative period. This dual approach enhances patient safety and treatment efficacy.

Other options may compromise the management of either the anticoagulant or infection treatment. For instance, stopping heparin could pose significant risks related to the PE itself, while combining the administration could result in complications or diminished effectiveness of either medication. Holding vancomycin may delay necessary antibiotic therapy, which is vital if there is a suspicion of infection following surgery.
