b. Name some examples of each and how they might affect the physiology of the respiratory system.
Students' answers should include the following:
a. Discussion of air resistance and lung compliance should include the airway diameter, flow rate of the air, resistance related to rate of breaths, and stiffness of the lung tissue in relation to mucus, foreign material, edema, and spasms.
b. Included in this discussion should be the amount of surfactant present, why there is more or less of surfactant, edema, atelectasis, fibrosis, air flow speed and rate, and the width or narrowing of airways and why they are that way.

The client who regularly uses a metered-dose inhaler four times a day tells the nurse that it is difficult to tell when the canister is empty. What instruction should the nurse give this client?
1. Place the canister in a bowl of water. If the canister floats, it is not empty. 2. When you get a new canister, divide the number of puffs that is listed on the label by four. That will tell you how many days the canister will last. 3. You can tell that the canister is empty when you can no longer smell the medication when you activate the plunger. 4. When you feel like you are no longer getting maximum effect from the medication, your canister is empty.
