A patient, recovering from a heart transplant, is scheduled for a heart biopsy. The nurse realizes that the purpose of this biopsy is to
1. measure tissue oxygenation status.
2. determine if rejection is occurring to adjust immunosuppressive medications.
3. treat atrial fibrillation.
4. determine ventricular functioning.
2
Rationale: A biopsy of the right ventricular wall is obtained approximately 1 week post heart transplantation. The biopsy results can definitively indicate whether rejection is present and to what degree. Immunosuppressant therapy can then be adjusted to halt the rejection process. Heart biopsy post transplantation is not done to measure tissue oxygenation status or to treat atrial fibrillation. Heart biopsies do not determine ventricular functioning.
