A patient with pneumonia in the right lower lobe is prescribed percussion and postural drainage. When performing percussion and postural drainage, the nurse should position him:

When performing percussion and postural drainage for a patient with pneumonia in the right lower lobe, the nurse should position the patient in a prone or supine position with the foot of the bed elevated higher than his head. This position helps to promote drainage of secretions from the affected lung segment by using gravity to assist in mobilizing and expectorating the secretions. Placing the patient in a prone or supine position with the foot of the bed elevated higher than the head helps to improve the efficiency of postural drainage and percussion techniques.

Options A, B, and D are incorrect because they do not provide the optimal position necessary for effective percussion and postural drainage in a patient with pneumonia in the right lower lobe.
