Explanation
Answer: c. Continuous positive airway pressure (CPAP) mask
Explanation: CPAP mask provides positive pressure throughout the respiratory cycle, including expiration, and is effective in delivering the necessary PEEP in clients with ARDS.
Incorrect choices: a. Non-rebreather mask does not provide positive pressure and is not the appropriate choice for delivering PEEP.
b. Venturi mask is not designed to provide PEEP.
d. Bag-valve-mask device is typically used for manual ventilation and resuscitation, not for delivering continuous positive pressure.
