The nurse is caring for a patient with pulmonary consolidation of the right lung. Which of the following positions would be most advantageous for this patient?
1. supine
2. right side down and elevation of 30 degrees
3. left side down and elevation of 30 degrees
4. left side down and flat
3
Rationale: Positioning the patient at 30 degrees and left side down will lower the diaphragm allowing more expansion and redirect blood flow to the healthy lung because of gravity. Air is naturally drawn toward the diaphragm and because blood is gravity dependent the ventilation–perfusion ratio will be improved. If the right lung is not capable of normal ventilation, redirecting blood flow would result in a mismatch. The positions of supine or flat will not improve ventilation-perfusion for this patient.
