Which is a function of the respiratory system?

Oxygen diffuses across the alveolar membrane into the blood.

The alveoli have cilia that help remove foreign particles.

The diaphragm controls respiration.

The bronchioles contain macrophages that phagocytize inhaled bacteria.

Answer and Explanation

The Correct Answer is A

A. Oxygen diffuses across the alveolar membrane into the blood: This is the primary function of the respiratory system, ensuring oxygenation of blood.
B. The alveoli have cilia that help remove foreign particles: Cilia are present in the respiratory tract, but not in the alveoli.
C. The diaphragm controls respiration: The diaphragm assists with breathing but does not "control" respiration, which is regulated by the brainstem.
D. The bronchioles contain macrophages that phagocytize inhaled bacteria: Macrophages are found in alveoli, not the bronchioles.

Correct Answer is D

Explanation

A) Took five quick "huffs" and then coughed vigorously. Huff coughing is a technique used to clear secretions, but it is not the correct method for using an incentive spirometer.
B) Exhaled deeply and then inhaled quickly and forcefully three times. Rapid inhalation and exhalation do not promote effective lung expansion or alveolar recruitment.
C) Took five deep breaths slowly every 4 hours. This frequency is insufficient to prevent atelectasis and postoperative lung complications.
D) Took 10 slow, deep breaths every hour. Taking 10 slow, deep breaths every hour encourages full lung expansion and prevents complications such as atelectasis.

A. Loop the client's tubes carefully to prevent kinking. B. Clamp the tube when the client is ambulating. C. Place the client flat to avoid leaks in the tubing. D. Keep the collection device below the client's chest level.

Correct Answer is D

Explanation

A. Loop the client's tubes carefully to prevent kinking: Tubes should not be unnecessarily looped, as this may cause obstruction or tension.
B. Clamp the tube when the client is ambulating: Clamping increases the risk of tension pneumothorax and should be avoided unless prescribed for specific procedures.
C. Place the client flat to avoid leaks in the tubing: This position may compromise lung expansion; semi-Fowler’s or Fowler’s position is preferred.
D. Keep the collection device below the client’s chest level: This position uses gravity to prevent backflow of fluid or air into the pleural space.
