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%"
THE answer is E
Explanation: Cellulose is the major part of plant cell walls.
A person with acute hypoxemia may have hyperventilate and develop respiratory alkalosis.
<h3>
What is hypoxemia?</h3>
Low blood oxygen levels are referred to as hypoxemia, while the more generic word hypoxia refers to an unusually low oxygen level in any tissue, organ, or physiological system. Hypoxia can be brought on by hypoxemia (hypoxemic hypoxia), but it can also happen due to other factors including anemia.
Hypoxemia is typically defined in terms of a lower partial pressure of oxygen (mm Hg) in arterial blood, but it can also refer to a lower oxygen content (ml oxygen per dl blood) or a lower percentage of hemoglobin (the oxygen-binding protein within red blood cells) being saturated with oxygen, either alone or in combination.
Thus, rather of focusing on hypoxemia, the oxygen content of blood is occasionally used as a gauge of tissue delivery.
