Answer:
Correct answer is c. It is the final electron acceptor in the aerobic respiration.
Explanation:
Oxygen is a substrate of the aerobic respiration, but it is not the only one. Glucose is also a substrate.
Oxygen is used in the cells to be the final electron acceptor, this means that receives the electrons from NADH and FADH2. That is why, when there is no oxygen available for aerobic respiration, the NADH and FADH2 cannot be oxidized and therefore remain in their reduced form. As a consequence, they cannot be re-utilized during different cellular processes that are NAD+ and FAD dependant, such as glycolysis, pyruvate oxidation and cellular respiration. This means that the ATP synthesis stops.
Oxygen itself does not transport any electrones, this are transported by the cytochrome complex in the mitochondrial membrane. But oxygen is key in receiving those electrones, therefore a very important piece of the electron transport across the mitochondria.
The correct option is (c) 70%.
The nurse would document 70% blood oxygen saturation as normal for the patient.
What is Venous oxygen saturation?
- The amount of oxygen in the blood that returns to the right side of the heart after perfusing the entire body is known as venous oxygen saturation (SvO2).
- An abnormal SvO2 results from insufficient systemic oxygenation when the oxygen supply is insufficient to meet the metabolic demands of the tissues.
- To assess the severity of tissue hypoperfusion situations and the mixed venous blood oxygen saturation levels, continuous central venous oximetry (ScvO2) monitoring may be performed.
- As blood returns to the heart and pulmonary system to be re-oxygenated, a central catheter is inserted into the superior vena cava (SVC), and a sensor on the catheter monitors the oxygen saturation of the blood in the SVC. 70% is the average ScvO2 value.

I understand that the question you are looking for is "The nurse is using continuous central venous oximetry (ScvO2) to monitor the blood oxygen saturation of a patient in shock. What value would the nurse document as normal for the patient?
(a)60%
(b)50%
(c)70%
(d)40%"
Im not sure if this is a true or false question but if so its true
