A client asks the nurse what ventilation is. What is the most appropriate response by the nurse?
Correct answer
A
Rationale
The correct answer is A. Ventilation is the process of moving air into and out of the lungs, involving inhalation and exhalation. This response is accurate as it specifically defines ventilation in the context of respiratory function. Option B is incorrect because ventilation involves both inhaling and exhaling, not just taking a single breath in. Option C is incorrect as it refers to perfusion rather than ventilation. Option D is incorrect because it describes gas exchange, which is a component of respiration but not the same as ventilation.
