Which statement by the nurse when explaining the purpose of positive end-expiratory pressure (PEEP) to the family members of a patient with ARDS is accurate?
a. "PEEP will push more air into the lungs during inhalation."
b. "PEEP prevents the lung air sacs from collapsing during exhalation."
c. "PEEP will prevent lung damage while the patient is on the ventilator."
d. "PEEP allows the breathing machine to deliver 100% oxygen to the lungs."
ANS: B
By preventing alveolar collapse during expiration, PEEP improves gas exchange and oxygenation. PEEP will not prevent lung damage (e.g., fibrotic changes that occur with ARDS), push more air into the lungs, or change the fraction of inspired oxygen (FIO2) delivered to the patient.
