Answer:

The semilunar valves open during the ejection phase due to the pressure on the left ventricle being higher than the pressure in the aorta and pulmonary artery.

Explanation:

During the ejection phase occurring in the ventricular systole, the pressure in the left ventricle increases and overpasses the pressure in the aorta and pulmonary artery. At this point the semilunar valves open, allowing the blood to flow from the ventricle into the arteries.

labwork [276]

Capecitabine has been prescribed for a client with breast cancer and the test that will be done periodically is Complete Blood Count.

<h3>What is complete blood count?</h3>

A complete blood count (CBC) is a blood test used to assess your general health and find a number of illnesses, such as leukemia, anemia, and infections.

A complete blood count test evaluates several elements and characteristics of your blood, such as:

A red blood cell carries oxygen.

Virus-fighting white blood cells

The oxygen-carrying protein in red blood cells is called hemoglobin.

Hematocrit, which is the ratio of red blood cells to plasma, the liquid component of your blood

The blood clotting factor platelets

A complete blood count that reveals abnormal increases or declines in cell counts may point to an underlying medical problem that necessitates additional testing.

The nurse is using continuous central venous oximetry (scvo2) to monitor the blood oxygen saturation of a patient in shock. what

bagirrra123 [75]

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.
