The home health nurse recommends that a patient with respiratory problems install a carbon monoxide detector in the home. What is the rationale for the nurse's action?
 
  a. Carbon monoxide detectors are required by law in the home.
  b. Carbon monoxide tightly binds to hemoglobin, causing hypoxia.
  c. Carbon monoxide signals the cerebral cortex to cease ventilations.
  d. Carbon monoxide combines with oxygen in the body and produces a deadly toxin.

Question 2

The patient is breathing normally. Which process does the nurse consider is working properly when the patient inspires?
 
  a. Stimulation of chemical receptors in the aorta
  b. Reduction of arterial oxygen saturation levels
  c. Requirement of elastic recoil lung properties
  d. Enhancement of accessory muscle usage

Answer to Question 1

ANS: B
Carbon monoxide binds tightly to hemoglobin; therefore, oxygen is not able to bind to hemoglobin and be transported to tissues, causing hypoxia. A carbon monoxide detector is not required by law, does not signal the cerebral cortex to cease ventilations, and does not combine with oxygen but with hemoglobin to produce a toxin.

Answer to Question 2

ANS: A
Inspiration is an active process, stimulated by chemical receptors in the aorta. Reduced arterial oxygen saturation levels indicate hypoxemia, an abnormal finding. Expiration is a passive process that depends on the elastic recoil properties of the lungs, requiring little or no muscle work. Prolonged use of the accessory muscles does not promote effective ventilation and causes fatigue.
