A patient has a hemoglobin level of 8.6 mg/dL. The nurse realizes that which of the following oxygenation components will be affected in this patient?
1. oxygen delivery
2. pulmonary gas exchange
3. oxygen consumption
4. diffusion of oxygen
1
Rationale: The concept of oxygenation involves three physiologic components for the intake, delivery, and use of oxygen for energy: pulmonary gas exchange, oxygen delivery, and oxygen consumption. Adequacy of oxygenation depends on the integration of these physiologic components. Pulmonary gas exchange involves the intake of oxygen from the external environment into the internal environment and is carried out by the processes of ventilation, diffusion, and perfusion. Oxygen delivery is the process of transportation of oxygen to cells and is dependent on cardiac output, hemoglobin saturation with oxygen, and the partial pressure of oxygen in arterial blood. Oxygen consumption involves the use of oxygen at the cellular level to generate energy for cells to use to perform their specific functions.
