Answer:
The correct option is : a. The phrenic nerve from the cervical plexus
Explanation:
The diaphragm is a thin skeletal muscle which separates the thoracic cavity and the abdominal cavity.
The phrenic nerve is a nerve present in the thoracic region, that passes down between the heart and the lung and reaches the diaphragm.
The phrenic nerve innervates the diaphragm from the C3–C5 of cervical plexus.
Pregnancy has no effect on blood flow. receiving a blood transfusion increases blood flow greatly.
<h3>What is blood transfusion?</h3>
Intravenously putting blood components into a person's circulation is known as a blood transfusion. For a number of medical disorders, transfusions are performed to replenish lost blood components.
Patients who have sustained major injuries in vehicle accidents or natural disasters are treated with blood transfusions. Blood transfusions are frequently given to people who have a condition like leukemia or kidney disease, both of which can induce anemia.
Through a little tube inserted into a vein in your arm, donated blood is given to you as part of a standard medical operation known as a blood transfusion. Blood lost during surgery or an accident can be replaced with the aid of this potentially life-saving technique.

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.
