A Patient Has Been Ordered to Receive IPPB in the Intensive

A patient has been ordered to receive IPPB in the intensive care unit.He has an arterial line in place which indicates a decreased blood pressure during the therapy.How can this be corrected?

A) Discontinue therapy immediately. Stay with the patient and closely monitor the respiratory rate and depth, pulse, and blood pressure. Observe the patient for signs of cyanosis. If respiratory arrest occurs, initiate cardiopulmonary resuscitation (CPR) and get help.
B) Discontinue the therapy. Try to administer therapy with the patient in semi-Fowler's or full Fowler's position, if possible, to help reduce the effects of IPPB on intracranial pressure
C) Terminate the IPPB therapy. Quickly auscultate the chest. Monitor the respiratory rate and depth and pulse frequently.
D) Discontinue the therapy and monitor the patient closely. Continue monitoring the patient. If the blood pressure remains low and the cardiovascular system fails to recover after discontinuance of therapy, contact the physician immediately.
