A patient's blood oxygen level is measured to be 78%. The nurse realizes that if this level continues, which of the following metabolic processes will occur?
1. anaerobic metabolism
2. aerobic metabolism
3. catabolism
4. anabolism
1
Rationale: Anaerobic metabolism is partially a compensatory mechanism that allows energy production to proceed whenever energy demands exceed the oxygen supply, such as during exercise. Anaerobic metabolism, however, is intended only to be temporary and cannot sustain life indefinitely. Aerobic metabolism occurs in the presence of oxygen. Catabolism is the process by which complex nutrients and body tissues are broken down into more basic elements such as glucose, fatty acids, and amino acids for the purpose of liberating energy necessary to maintain bodily functions. Anabolism is the process of cell synthesis which builds body tissues.
