A 35-year-old woman was diagnosed with cancer of the right breast, which required a mastectomy. An implanted port was placed on the left chest wall. X-ray verifies catheter tip placement in the brachiocephalic vein. The nurse accessed the port and documented that no blood return was obtained. However, believing the port was patent, even though she did not obtain blood return, the nurse infused ondansetron (Zofran), followed by an injection of 60 cc of doxorubicin (Adriamycin). After the nurse injected the doxorubicin, she once again documented the absence of blood return. As the drug was being injected, the patient complained of pain in the lower chest area below the ribs. Realizing this is not a normal reaction, the nurse discontinued the injection of the chemotherapeutic agent. The patient again complained of severe chest pain with a burning sensation in her lower chest area. The nurse notified the physician of the change in the patient’s condition. A chest X-ray and cathetergram were ordered. The test results showed the catheter tip had punctured the vein wall and the medication was injected into the left chest cavity, resulting in permanent scarring of the left lobes of the lung. Although the patient’s cancer was cured, she was left with a permanent lung deficit.
