The nurse is educating a patient's family member about a pulmonary artery catheter (PAC). Which statement by the family member best indicates understanding of the purpose of the PAC?
a. "The catheter will provide multiple sites to give intravenous fluid."
b. "The catheter will allow the physician to better manage fluid therapy."
c. "The catheter tip comes to rest inside my brother's pulmonary artery."
d. "The catheter will be in position until the heart has a chance to heal."
B
A pulmonary artery catheter provides hemodynamic measurements that guide interventions that include appropriate fluid therapy. Even though a pulmonary catheter provides multiple intravenous access sites, this is not the primary purpose of the catheter. Although the catheter is positioned in the pulmonary artery, positioning is not the purpose of the catheter. The primary purpose of the catheter is not to aid in the healing of the heart but to guide therapy.
