A patient is receiving 35% oxygen via a Venturi mask. To ensure the correct amount of oxygen delivery, which action by the nurse is most important?
a. Teach the patient to keep mask on at all times.
b. Keep the air entrainment ports clean and unobstructed.
c. Give a high enough flow rate to keep the bag from collapsing.
d. Drain moisture condensation from the oxygen tubing every hour.
ANS: B
The air entrainment ports regulate the oxygen percentage delivered to the patient, so they must be unobstructed. A high oxygen flow rate is needed when giving oxygen by partial rebreather or non-rebreather masks. Draining oxygen tubing is necessary when caring for a patient receiving mechanical ventilation. The mask is uncomfortable and can be removed when the patient eats.
