A nurse is explaining the process of respiration to a client. Which information should be given?

Question

1. "Moving air in and out of the lungs is really called ventilation."
2. The smooth muscle in the alveoli helps to pull air into the lungs.
3. Exchange of oxygen and carbon dioxide occurs across a thin capillary membrane.
4. Respiration is not effective without perfusion.
5. Your basic respiratory drive is determined by your brain.

Answer 1

Correct Answer: 1,3,4,5
Rationale 1: Ventilation is the process of moving air into and out of the lungs.
Rationale 2: There is no smooth muscle in the alveoli.
Rationale 3: The blood stays in capillaries. A thin membrane separates airway from capillary.
Rationale 4: Perfusion is the blood flow through the lungs. Without this blood flow, the oxygen–carbon dioxide exchange does not take place.
Rationale 5: The rate is determined by neurons in the brainstem and can be affected by a number of factors.
