A client is experiencing atelectasis. The nurse anticipates that this client will have an alteration in:
 
  1. Ventilation.
  2. Alveolar gas exchange.
  3. Transportation of oxygen and carbon dioxide.
  4. Systemic diffusion.

Question 2

A client who was a victim of a house fire is coughing. The nurse realizes that the purpose of the cough is to:
 
  1. Improve oxygenation.
  2. Remove irritants from the nasal passages.
  3. Remove irritants from the trachea or bronchi.
  4. Close the glottis.

Answer to Question 1

Correct Answer: 1
Rationale 1: Atelectasis affects lung compliance, which is a condition that needs to be present for adequate ventilation.
Rationale 2: Alveolar gas exchange is the diffusion of oxygen from the alveoli and into the pulmonary blood vessels, and occurs after ventilation.
Rationale 3: Transportation of oxygen and carbon dioxide occurs in the blood.
Rationale 4: Systemic diffusion of oxygen and carbon dioxide occurs between the capillaries and the tissues and cells.

Answer to Question 2

Correct Answer: 3
Rationale 1: Coughing does not improve oxygenation.
Rationale 2: Sneezing removes irritants from the nasal passages.
Rationale 3: The trachea and bronchi are lined with mucosal epithelium. These cells produce a thin layer of mucus that traps pathogens and microscopic particulate matter. These foreign particles are then swept upward toward the larynx and throat by cilia. The cough reflex is triggered by irritants in the larynx, trachea, or bronchi.
Rationale 4: Swallowing closes the glottis.
