Vedmedyk [2.9K]

Answer:

hemoglobin will bind more oxygen when the partial pressure is low than when the partial pressure is high.

Explanation:

Binding of hemoglobin to oxygen is regulated by several factors. However, the partial pressure of oxygen is the most important factor that determines how much oxygen will bind to hemoglobin. When the partial pressure of O2 is high, hemoglobin binds with large amounts of O2. On the other hand, when the partial pressure of O2 is low, hemoglobin is only partially saturated.

Therefore, the greater the partial pressure of oxygen, the more O2 will bind to hemoglobin until saturation is reached. This is why a lot of O2 binds to hemoglobin in pulmonary capillaries where the partial pressure of oxygen is high.

At this time the client is still too anxious to be capable of coping with the reasons for handwashing. Continued handwashing does not reveal an understanding of the underlying problem, nor is it a sign of progress. Telling the client not to worry denies the client's feelings and may close off communication.</span>
