The primary effect of chronic fevers on the body's respiratory functioning is seen in:
 
  1. Increased oxygen requirements that exceed the body's ability to satisfy its needs
  2. Increased respiratory rates that tax the body's reserves of stored energy
  3. Breakdown of muscle mass, causing ineffective intercostal muscle function
  4. The presence of a sense of general malaise that stresses the immune system

Question 2

Pregnancy affects a woman's oxygenation needs primarily because of:
 
  1. The increased metabolic demands required to support the fetus
  2. The increased tendency to develop anemia as a result of low iron reserves
  3. The decreased ability to engage in the physical exercise required to promote cir-culation
  4. The decreased lung capacity resulting from the pressure of the uterus on the dia-phragm

Answer to Question 1

ANS: 3
When fever persists, the metabolic rate remains high and the body begins to break down protein stores, resulting in muscle wasting and decreased muscle mass. Respiratory muscles such as the diaphragm and intercostal muscles are also wasted. Although the remaining options are not in-correct, they do not represent the primary effect.

Answer to Question 2

ANS: 1
Increased metabolic demands, such as pregnancy or fever and infection, affect a client's oxy-gen-carrying capacity (of the blood). The remaining options can affect respiratory function but are not the primary cause of increased oxygenation requirements.
