Final answer:
The elderly woman's risk factors for developing hypoxia include anemia, impaired cardiac function, shortness of breath, and pneumonia, all contributing to poor oxygenation levels.
Step-by-step explanation:
The risk factors for the elderly woman developing hypoxia in the context of her present clinical condition include: A. Anemia - which can reduce the oxygen-carrying capacity of the blood, D.
Impaired cardiac function - as a history of heart failure can lead to inadequate circulation and oxygen delivery, E. Shortness of breath - making it hard for her to maintain adequate oxygen levels, especially during activity, and F. Pneumonia - which affects gas exchange in the lungs due to the presence of fluid in alveoli and can worsen hypoxia. These factors contribute to the risk of developing hypoxia due to compromised lung function and oxygen transport.
